I got the same shit on a Volvo. Nothing like just driving normally and then it starts beeping and flashing and slams on the brakes with no one in front of you.
Now about the Mercedes safety in real-life. I got nearly killed by Mercedes emergency braking system. While driving through a curve, fully loaded, the sensor indicated something (a rain drop, autumn leaf idk) and started braking with full force in the middle of the curve. Great experience, had to do my best to stay on the road.
I turn all the crap off! Lane assist and collision alert! I frickin hate it when 'it' thinks!!!!!! I'm the bloody driver, let me drive! This shit is because drivers will drive tired or drunk or drugged or on the phone or reading a map and people have died cos they not paying attention! So us professional professionals have to suffer! It like race cars, drivers love a raw car, start putting computers on it to help, drivers hate it!
@@terrystratford1235 That's why I love 90s cars and trucks, too old means harder to find parts, too new means too many unstable computers. 90s are just right.
Happened to me it kicked in when raining and the car passed me on the m1 with fog lights on just took a noise dive drive a man truck now no problems yet!!!
Very good answer. They could also show that the tyres are in similar condition, and do the tests with the trucks swapped from one lane to the other, just to cancel out differences in the tarmac- who knows if one of the lanes is covered in bits of rubbed-off rubber from a previous test?
Retired at 68 lady trucker here. I watched a UA-cam vid a few months ago showing a school bus dropping kids off at a stop on a busy, fast flowing highway. One young boy ran around the front of the bus, straight into the path of an artic/18 wheeler travelling around 40+ mph. Cant recall the make of the truck but couldn’t believe how the driver brought it to an almost instant stop before hitting that kid. The whole truck and trailer reared up. Alert driver and new fangled braking systems saved that kids life and a families lifetime grief 🙏
Reducing braking distances for safety is good, but there is one thing to keep always in mind: when moving loads of tons, short braking distances could be not so much safer. You're traveling at 80 km/h with a load of what, 5 tons, you brake for an emergency and you stop in 41 meters. The load will do the same? 5 tons at 80kn/h have an immense kinetic energy and the only things that counteract it are the fixing systems of the cargo, if not done properly an emergency braking so powerful like that could end in a catastrophic and potentially fatal accident by cargo displacement.
@@mb-fs1yo Agreed,a couple of years back my Iveco spec truck had both sets of keys stolen,the dealership sent an enormous Scania tilt and slide to load it on.When it was loaded I can remember actually thinking,to my self, f**k that! There is 11.5 tons of truck with probably a ton of two of tools,jack's,spec adapters etc. On board with quite a high centre of gravity now sitting 5 foot off the floor on a relatively shiny surface being held by just 3 not entirely suitably sized ratchet straps,if he corners too quickly it's coming off or if he brakes hard it's coming through his cab,the bulkhead being just some small box section and a mesh.Despite his assurance,bragging of how he regularly loads 2 giant tractors at once etc. the inevitable happened,the single rear strap broke and my truck shunted forwards,the 600kg solid block of steel counterweight welded across the front chassis pulverised his deck winch and half pulled it out of its chassis mountings,fortunately for him it did stop my truck because it was the only thing between it and the back of his mesh bulkhead and tissue paper cab,lucky bastard!
Thats incedible... bringing 40T to a stop in just twice the length of its self... as a driver you may never have to put that brake pedal all the way to the floor in your whole life but if you do... its nice to know its gonna do the job.
Interesting thought: One vehicle that I used to drive, an 11/1979 build tandem tray top with a single axle trailer on behind, the brakes were such on that truck, that, even with 4 tonne more than what should have been on the truck, it would outperform some cars in braking at traffic lights. To the point that I was even abused by a copper for causing the copper to have to take evasive action to avoid running into the trailer! Copper tried the overweight trick on me... But, how could I have stopped quicker than you if I am overweight??? This was at a gross weight of 32.5 tonne, over 4 axles. Eventually, the brake shoes got down to the rivets, and the shoes were replaced. With the new shoes, the braking capacity went out the window, and had to allow an extra 10 metres at 60 km/h. As for the torque / horsepower argument... it also comes down to gearing. One other truck that was a joy to drive was an old Scania, 6/1977 build, 296 b.h.p., 1070 Nm of torque. Pulled out of a yard in the hills, gross weight of 34.5 tonne. Company truck follows me out of the yard, he is 42.5 tonne, 460 horsepower Cummins in a Sterling prime mover. Now, on paper, the company truck has the better horsepower to weight ratio, and should get away from me. Company truck is electronically limited to 100 km/h, mine is gearbound to 88 km/h. Went up the first hill, got away from him, over the top, my practice is to ride the exhaust brakes and change up through the gears to hit the bottom of the hill doing 84 km/h / 2100 r.p.m., then hold that speed for the start of the next hill, which is a 2 km, 6% grade. Company truck got away from me on the downhill and flat, but, I went past him with a 10 km/h speed difference at about the 1.6 km mark on the next climb... how is this so??? It all comes down to the gearing!!! To further reinforce this point... A 112 Scania, 305 h.p., 3.89 diff ratio, used to tow a triaxle cement tanker out of Geelong to Adelaide. He would be loaded to 42.5 tonne at Geelong, and would use 350 odd litres of fuel for the trip back to Adelaide. So, on the last Mermaids weighbridge, his gross weight would be 42.2 tonnes. Going up the dipper, he would be in 4th gear at 15 km/h. The last load that was done with this truck as a prime mover was a load of railway sleepers out of Tailem Bend. At the Mermaids weighbridge: Steer: 5.40 tonne, tandem drive: 17.20 tonne, triaxle trailer: 20.70 tonne - Gross: 43.30 tonnes. (Yes, the knuckles got rapped / spanked by the Mermaid!) Going up the dipper, held 7th gear, 1400 r.p.m., 25 km/h.. This is in a 111 Scania, 296 h.p., 4.86 diff ratio.
The new brake sensors on the new mercs can be scary if you on a bend and a twig sticking out it locks your brakes I get it all the time,I say bring back the old trucks better to drive than new ones
First of all: Brakes don't lock on newer vehicles. It's a benefit of driving a newer vehicles, meaning you'll have better control in braking situations. Secondly, no. You're just being nostalgic, and are being stubborn towards new tech.
@@timderks5960 Doesn't change the fact that sudden hard braking is going to upset the stability of a 40+ Ton truck going through a corner, regardless if the brakes lock or not. Ever heard of weight transfer?
@@Cozzy-Wozzy No, you're right, it doesn't change that very specific fact that you picked for a very specific reason. It does however make a massive difference how the truck responds to this stability change. The old truck is guaranteed to lock up all wheels, which combined with the stability change will absolutely guarantee that it starts sliding when cornering. On a new truck, this risk is massively reduced. Also, weight transfer has absolutely nothing to do with this, but yes, I've heard of it, many times.
@@timderks5960 Its really not a very specific situation, and it does happen, multiple guys have complained that it detects small sticks, bushes. And very small miniscule stuff like rubber from blown tires etc. darting out from ditches and what not, and I've even seen in a few videos for American trucks with the system where it automatically brakes because it see's a bridge over the road.
Very impressive video! but my heart goes out to all your Truck Drivers in the comment section - Sorry to hear you have bad experiences with whatever truck you're driving, but do note that your sacrifices, hard work and continued dedication to making sure that shelves are stocked with all the stuff we, the consumers want, is highly appreciated and couldn't be done without you! I have a brother currently taking his truck drivers license, please accept my apologies on behalf of my ignorant fellow citizens, who hates you for being on the road and 'slowing things down', they don't realize what important role you really play in the greater scheme of things, and for that, I am sorry! Keep up the hard work! love you guys! Keep on Trucking! PS: Sorry for the wall of text.
The same as on the other trailer, as it’s stated in the video. Both weighing in at about 38,5 tons. Why should they have set this up? Isn’t it logical for a truck that is about 30 years older to have a longer braking distance (old abs, old disc or even drum brakes). The same evolution happend also to normal passenger cars.
@@fideramirez8611 Do I have to repeat myself? Why should they lie??? There is no logical reason for them to lie. It’s just normal that modern trucks to have a shorter braking distance than a 30 year old one. Like I said, a Golf 2 also has a longer braking distance than a Golf 7 eventhough it is lighter.
New vehicles are too over-engineered...even to the rims! Too computerised and too many electronics that go bad often...so yeah, the 90s one will live on...
Because that is not a requirement for the development of a truck. What company uses the same vehicles for 30 years? No serious one does. And the manufacturer doesn’t care about the used vehicle market. They want go sell the best new product. Also, government regulations and people striving for comfort hardly gave them any choice other then overcomplicate the whole truck.
@@starstencahl8985 so let's go back for times when quality and brand were more important than quantity. 1960's, 70' 80'... Somehow then the trucks ran without repairs for 20-30 years. Leyland, Man, Volvo, Scania, Mercedes, Om, Saurer, Fiat and on US Mack, Peterbilt , Ford and many others produce trucks that break down little and drive long. All these companies were not serious then? But the economists said they wouldn't make money this way. On the one hand, they talk about ecology, and on the other side, they produce items that will last for ~5 years they cost more and produce more waste.. This is just lie. Additionally, people today are getting lazier and dumber. And these old trucks still go and works on many places and earn their living ...
@@jmfjcas6014 Yeah, I'm completely on your side with that. But that is sadly what the market demands nowadays and manufacturers have little to say about how they want to build their vehicles, if they want to stay competitive
It's nice to know you get something for all that high tech engineering designed to be impossible to maintain self-sufficiently. I'd still take the old truck, look a bit further ahead for hazards and take my chances.
@@Fishmans Yes, take my chances. It's not the dead cyclist or motorist who has to live with it afterwards, it's the driver who survived, a dubious advantage. Besides, if you're driving such that you cannot stop in the available distance, then you're doing it wrong, point blank. Also, the highway code is written with older vehicles in mind, so it's not like longer braking distances haven't been planned for. P.S. Don't forget to adjust your damned brakes. They do wear down.
Fixing brakes old one. 300$ , just put something from replacement. 100$ for fix. Fixing brakes in new one. 3 000 $ Ordering parts from china 3 months. Repair shop fees 2 000$ , truck wont move until you place 1 and only part from producer.
Truck drivers sometimes think that they are driving a small vehicle, they forget that it requires more distance to brake, that's why so many accidents, specially here in Mexico where I live.
41m is only a couple of meters more then a car which would be around 37-38m. and that with 38.5t of load. people think that these things cant brake when they can brake almost as fast as cars at that speed
@@sgxbot I am talking about Mexico... There are almost no new trucks, most of them are ten or more years old, and they get almost no maintenance. They are only repaired when they break down... That's why it's so dangerous.
To all the people saying switch trailer, switch drivers, switch gender, switch planets for variance of gravitational anomalies. I am certain the company didn't just wing the video in 1 minute and 12 seconds and that was all the effort put into it. They wanted to make a statement about safety and how future technology has improved it. They made their point, there didn't have to be a 45 minute in depth video. I think we can all believe technology on trucks has improved. They just gave us a simple example. I mean if this is a conspiracy then who cares, more than likely when it counts the roads are icy anyways.
@@kstudios8706 the old one only half braked. older trucks dont have the safety systems newer ones do so fully locked brakes are actually fully locked and could stop way sooner then a newer truck but more violently and alot higher risk
Wszystko fajnie, tylko że "stara" ciężarówka to model który w produkcji znajdował się od 1989 roku. Bardziej uczciwie byłoby porównać z pierwszą generacją Actrosa, która do produkcji weszła w 1996 roku, a więc w 1997 była modelem nowoczesnym, a nie konstrukcją ośmioletnią.
Sidenote... The modern one with the ABS started slipping and it kinda got out of the straight line. The Older model with drumbrakes... Remained stable....and in a straight line... I know which one id choose... The old Model all day every day. The romance of trucking is oldschool... The Modern thing is automated to big boredom. Sooo #Dekra do a real honest test which one is actually safer... You will be amazed to see the Older model is safer.
People killed in traffic accidents in Germany: 1997: 8549 2017: 3180 Death per 100.000 vehicles: 1997: 16.9 2017: 5.5 I definitely see why you would say that the older truck is safer...
I would drive that old SK any day, all day...... OK, the Actros is a very nice modern truck and the SK's stopping distance is longer but I prefer to actually "feel" the truck I'm driving rather than sit on top of a big computer...........
I don‘t get why people think this is a set up. Why are you surprised that a older truck without modern abs and esp and with older disc or even drum brakes has a longer braking distance than a modern one? They chose a closed trailer because that was the one they had at hand. It is clearly stated in the video that they both weigh in the same. Again, why should the have set this up. The DEKRA is an wourldwide operating audit company which is also allowed to take the mandatory technical exam for passenger cars in Germany.
These tests are always Manipulated to suit the Desired outcome . Of course the New tech is Better that I’m not disputing , but what is the Condition of the Brakes on the Old model?
@@bertiewooster3326 Exactly Too many variables , what about the Condition of the tyres ? The weight of the Trailer ? Driver reaction? Quite a few things to consider
...obviously someone doesn't know the trucks length, the difference is only 16m, but the length of a standard truck is nearly 19m so how come the older truck is so much ahead, I think the lenght difference should be about 23-24m if you judge by the Video...
spent a year driving a 2018 actros after 2 year driving a 96 daf cf. its incredible the difference. i had a car pull out on me in milton keynes in the merc, dented quarter panel to the car, broken number plate on the truck, had it of been the daf i expect there would have been a fatality
Who else with even basic vehicle knowledge noticed the guy in the older truck wasn't even trying to stop fast older trucks don't have abs so have a quicker skidding stop but that puts more wear and tear on the truck thats why they aded abs to save people money since the truck in this video didn't drag even a single tire but the new truck did either the breaks are faulty and don't work so the vid isn't a good even comparison or they did it on purpose to pretend newer trucks are better at stopping also the kind of tire has a huge impact on how fast a vehicle can stop so of course they left that out
This probably has more to do with disc vs drum brakes and condition of the braking system on the older truck. Put all new brake linings, drums, slack adjusters, s-cams, and then do the test
Why? If they wanted to cheat the test, they would cheat it in a different way. And if you want to suspect them in cheating, you'd find other reasons to do so.
It explains nothing! We don’t hear any details why there is such a difference: Is it the truck or the trailer brakes? Is it the size of the brake disks, material of pads? This video says nothing!
Disc brakes on the unit all round, trailers have abs and ebc and other 3 letter acronyms! Tyres are better! Also newer hgv and trailers are lighter, so the pay load can be increased!
@@demil3618 kind of! Older units may have disc braking on the steer wheel, but drum brakes on the lift and drive axles! As for trailers, a brand new, skelly (containers) car transporter or fridge, especially double Deckers are really heavy empty! Possibly upto 15 ton! An empty flatbed probably only 10 ton!
@@demil3618 let's not forget tyres also! Now you can chose for fuel or grip! But the tyres now whatever you have are soooooooòoo much better than old radials!!
@@3DPeter true. Just a very simple example of real life situation for an ordinary person to see, without overloading it with a lot of math and engineering standing behind it.
i would asume improvements in the anti lock system. keeping the tire at the optimal slip point where you have max brake performance and not just increasing brake pressure until lockup and then releasing it a bit to get the tire rolling again as it used to be.
Just curious about this test as the trailer brakes also has a huge impact in fact the brakes of the trailer caries the load of what's within it the trucks brakes allows for both to come to a controlled stop ... Why is it two different trailers ?
Because the brakes on the old truck is just much worse and doesnt brake as hard, thats why there isnt any smoke, not hard to understand, the old truck just performaned bad due to its inferior technology in brakes and braking system. They are trying to show the difference in the new vs old technology and brakes and brakes should behave the same even if they arent new as long as they isnt completly worn out.
@@freevideos051 I highly doubt they are worn out, were do people get that impression, you do know what worn out means right? Theres a difference in worn and worn out and in most of the cases the brakes should function the same worn or new, if they are worn OUT I can understand it, but they are probably not, just accept already that modern tech is better then 90s tech.
At the end Newer is beter, safer breaking at least. But this test is not fair because of human factor. Old one braking late.Which makes huge difference at result.
There’s a difference between a 20 year old truck and a 20 year old truck with 20 year old brake pads. Truck break technology hasn’t changed much in 20 years, the only difference is ABS really
it has gotten a lot better. back then the abs would lock up and unlock the tire multiple times per second. today the tires dont even lock up anymore when above 5 kmh or something like that.
@@sgxbot That most likely has more to do to with high speed electronics than anything else: when ABS works its magic, huge, HUGE currents flow through the electrical system as it tries to regulate braking power as good as possible. Besides a possible 'arm system for impact' (deploy airbags), this is the sole reason the audiosystem in a car can stop working when doing an emergency stop (did such a stop on purpose once on an empty motorway, doing 80 km/h (had just sped up coming from the slip road, and the sound system immediately stopped working as soon as I fully braked). Electronics have improved so significantly in speed, efficiency and such that the computers are now far faster and (thus) far more able to keep the wheels from temporarily locking up. If the same ABS system would be fitted on the newer truck, it would have the same outcome as on the old truck.
@@weeardguy that actually has not much to do with the faster electronics because its the sensors that are required to detect the amount of slippage etc that hasnt been around back then.
I wonder, why does the new truck have a closed box? Why they didnt show the cargo in the trailer? Is it because its an empty box? Put flat beds on both and i will believe it! For now its just fake for me!
It don't matter if there's a load or not. With a load you have more pressure on the tires, without the truck has less pressure, but also less weight. The brakes are made for the loaded truck, and the truck adjusts the brake force depending on the actual load. This has nothing to do with a passenger car.
@@simonm1447 More weight will mean longer braking distance. Just because you have more weight on the tires, and therefore more grip, it is NOT equivalent to simply having less weight.
@@reinbeers5322 I know it sounds strange, but an empty truck will really don't stop with a shorter brake distance than a fully loaded one. Brakes of semi trucks and their trailers are designed for full load, they can absorb the heat of an emergency braking maneuver. With a fully loaded trailer you have much more friction on the road, so the brakes can work with 100%, if the truck is empty they can't and work with less braking power. Modern trucks with air suspension calculate this with the acceleration (how fast it accelerates if it's leveled, they have a tilt sensor in the truck), older ones have a simple device which measures the suspension travel of the leaf springs. shannonlawgroup.com/calculating-stopping-distance-semi-trucks/ BTW, I had a education at Daimler when we picked up our new truck, and they told the same
Having driven both generations of this truck the test is very valid, whining about showing the inside of the curtain, and swapping trailers.......anyone who has driven both generations will attest how much better the braking is in the newer trucks. Dekra is one of the few independent organisations I actually trust. Rather suspect a lot of these comments are coming from wannabe truck drivers from ETS2 !!!!
Because this trailer didn't exist around the time of the old trailer (thus it's impossible to pair these because it wil make it unfair due to the combination of old and new).
I think the purpouse of this test is to show how stupid the regulations about speedlimits on german overland streets are. They were founded when those old trucks were around, and were never updated to justify the advancements. Back then 60km/h was alright, but now 70 or 80 would be alright too.
Would like to see sale test with same semi for braking performance of loaded semi and really diff on tractor. Must be less huge even bot changing the evolution
Did you put new brake pads and rotors on each truck, why didn’t both use similar trailers to make the experiment more accurate, where both truck the same class?
The purpose was to versus old and new, not old+new vs new+new. I think they wanted to show how stupid current speedlimits are on german roads are, because they were made back when trucks needed 20-30m more braking distance.
OMG, all those dumb comments. "If they would use the same trailer, and the same tires, and the same brakes and and and and.... the same components, so the old truck is equiped with all new tech it would have the same distance, duh". Again: The point is to test 2 vehicles of two different eras with their current technology and not new vs old with all new parts.
Having driven numerous different Merc Actros's I have to say they model in this video has terrible brakes. DPD use them, and apparently use genuine Merc brake pads, (I asked a mechanic whilst working there). You press the pedal and initially it feels good, but then feel like its not going to stop. The older Actros (Euro 5) the brakes felt great. I wouldn't like to drive that old banger of a truck in this video though, having just watched it trying to stop.

@handige rakkers Ofc.Cars and trucks are difrent
Weight maybe..
Reducing braking distances for safety is good, but there is one thing to keep always in mind:
when moving loads of tons, short braking distances could be not so much safer.
You're traveling at 80 km/h with a load of what, 5 tons, you brake for an emergency and you stop in 41 meters.
The load will do the same? 5 tons at 80kn/h have an immense kinetic energy and the only things that counteract it are the fixing systems of the cargo, if not done properly an emergency braking so powerful like that could end in a catastrophic and potentially fatal accident by cargo displacement.
Fixing the load properly is mandatory and it's controlled by the police. The load has to withstand a emergency brake with full power.
And everybody is super responsible and don’t use questionable equipment, that’s why you never see broken or torn tie downs along the road. Oh, wait.
@@mb-fs1yo Agreed,a couple of years back my Iveco spec truck had both sets of keys stolen,the dealership sent an enormous Scania tilt and slide to load it on.When it was loaded I can remember actually thinking,to my self, f**k that!

In Finland they did test with 76 T timber truck and stopped it in 49 m.

0:26 The SK truck braked later than the new one here as you can see, NOT FAIR! ofc a little different but it could make something
Agree.
The old one probably have drum brakes on all axles too. Switch with disc ones and it would fair the same as the new one
Not 16 meters later though.
and the question of what is under the tarpaulin
@@WEMBLEYNE disc brakes arent always the best ones...drum brakes can be better sometimes.
Fantastic to see how technology improves safety, especially when needed in emergency situation. Great video!
Sk, 141, Turbostar and F89....most beautiful european trucks ever
Interesting thought: One vehicle that I used to drive, an 11/1979 build tandem tray top with a single axle trailer on behind, the brakes were such on that truck, that, even with 4 tonne more than what should have been on the truck, it would outperform some cars in braking at traffic lights. To the point that I was even abused by a copper for causing the copper to have to take evasive action to avoid running into the trailer! Copper tried the overweight trick on me... But, how could I have stopped quicker than you if I am overweight??? This was at a gross weight of 32.5 tonne, over 4 axles. Eventually, the brake shoes got down to the rivets, and the shoes were replaced. With the new shoes, the braking capacity went out the window, and had to allow an extra 10 metres at 60 km/h.
As for the torque / horsepower argument... it also comes down to gearing. One other truck that was a joy to drive was an old Scania, 6/1977 build, 296 b.h.p., 1070 Nm of torque. Pulled out of a yard in the hills, gross weight of 34.5 tonne. Company truck follows me out of the yard, he is 42.5 tonne, 460 horsepower Cummins in a Sterling prime mover. Now, on paper, the company truck has the better horsepower to weight ratio, and should get away from me. Company truck is electronically limited to 100 km/h, mine is gearbound to 88 km/h. Went up the first hill, got away from him, over the top, my practice is to ride the exhaust brakes and change up through the gears to hit the bottom of the hill doing 84 km/h / 2100 r.p.m., then hold that speed for the start of the next hill, which is a 2 km, 6% grade. Company truck got away from me on the downhill and flat, but, I went past him with a 10 km/h speed difference at about the 1.6 km mark on the next climb... how is this so??? It all comes down to the gearing!!!
To further reinforce this point... A 112 Scania, 305 h.p., 3.89 diff ratio, used to tow a triaxle cement tanker out of Geelong to Adelaide. He would be loaded to 42.5 tonne at Geelong, and would use 350 odd litres of fuel for the trip back to Adelaide. So, on the last Mermaids weighbridge, his gross weight would be 42.2 tonnes. Going up the dipper, he would be in 4th gear at 15 km/h. The last load that was done with this truck as a prime mover was a load of railway sleepers out of Tailem Bend. At the Mermaids weighbridge: Steer: 5.40 tonne, tandem drive: 17.20 tonne, triaxle trailer: 20.70 tonne - Gross: 43.30 tonnes. (Yes, the knuckles got rapped / spanked by the Mermaid!) Going up the dipper, held 7th gear, 1400 r.p.m., 25 km/h.. This is in a 111 Scania, 296 h.p., 4.86 diff ratio.
Bloke in the SK Merc didn't press the pedal hard enough. Not one wheel locked; not even a puff of smoke. Bollocks test.
quite schewpid innit
TBH smoke in new one was from breakes not wheels.
If you hold brake to lock wheels... you take longer to stop cose rubber turns into fluid.

The new brake sensors on the new mercs can be scary if you on a bend and a twig sticking out it locks your brakes I get it all the time,I say bring back the old trucks better to drive than new ones
My antos 2643 only beeps usually, very rarely starts braking
First of all: Brakes don't lock on newer vehicles. It's a benefit of driving a newer vehicles, meaning you'll have better control in braking situations. Secondly, no. You're just being nostalgic, and are being stubborn towards new tech.
@@timderks5960 Doesn't change the fact that sudden hard braking is going to upset the stability of a 40+ Ton truck going through a corner, regardless if the brakes lock or not. Ever heard of weight transfer?
@@Cozzy-Wozzy No, you're right, it doesn't change that very specific fact that you picked for a very specific reason. It does however make a massive difference how the truck responds to this stability change. The old truck is guaranteed to lock up all wheels, which combined with the stability change will absolutely guarantee that it starts sliding when cornering. On a new truck, this risk is massively reduced.
Also, weight transfer has absolutely nothing to do with this, but yes, I've heard of it, many times.
@@timderks5960 Its really not a very specific situation, and it does happen, multiple guys have complained that it detects small sticks, bushes. And very small miniscule stuff like rubber from blown tires etc. darting out from ditches and what not, and I've even seen in a few videos for American trucks with the system where it automatically brakes because it see's a bridge over the road.

Show the contents of the second trailer...
My thought exactly.
Stay where you are!
The same as on the other trailer, as it’s stated in the video. Both weighing in at about 38,5 tons. Why should they have set this up? Isn’t it logical for a truck that is about 30 years older to have a longer braking distance (old abs, old disc or even drum brakes). The same evolution happend also to normal passenger cars.
They could be lying and using an empty box, why don’t they use the same trailers?
@@fideramirez8611 Do I have to repeat myself? Why should they lie??? There is no logical reason for them to lie. It’s just normal that modern trucks to have a shorter braking distance than a 30 year old one. Like I said, a Golf 2 also has a longer braking distance than a Golf 7 eventhough it is lighter.
This means the older drivers were supreme drivers in true sense.
Salute🙏
No, it means that there used to be more accidents, that's it.
Old is gold.
Old school trucking for live
..And now show me this "modern truck" in thirty years later. I'm sure, after next thirty years only this SK will still to ready to drive.
New vehicles are too over-engineered...even to the rims!
Too computerised and too many electronics that go bad often...so yeah, the 90s one will live on...
Because that is not a requirement for the development of a truck. What company uses the same vehicles for 30 years? No serious one does. And the manufacturer doesn’t care about the used vehicle market. They want go sell the best new product.
Also, government regulations and people striving for comfort hardly gave them any choice other then overcomplicate the whole truck.
@@starstencahl8985 so let's go back for times when quality and brand were more important than quantity. 1960's, 70' 80'... Somehow then the trucks ran without repairs for 20-30 years. Leyland, Man, Volvo, Scania, Mercedes, Om, Saurer, Fiat and on US Mack, Peterbilt , Ford and many others produce trucks that break down little and drive long. All these companies were not serious then? But the economists said they wouldn't make money this way. On the one hand, they talk about ecology, and on the other side, they produce items that will last for ~5 years they cost more and produce more waste.. This is just lie. Additionally, people today are getting lazier and dumber. And these old trucks still go and works on many places and earn their living ...
@@jmfjcas6014 Yeah, I'm completely on your side with that. But that is sadly what the market demands nowadays and manufacturers have little to say about how they want to build their vehicles, if they want to stay competitive

It's nice to know you get something for all that high tech engineering designed to be impossible to maintain self-sufficiently. I'd still take the old truck, look a bit further ahead for hazards and take my chances.
@@Fishmans Yes, take my chances. It's not the dead cyclist or motorist who has to live with it afterwards, it's the driver who survived, a dubious advantage. Besides, if you're driving such that you cannot stop in the available distance, then you're doing it wrong, point blank. Also, the highway code is written with older vehicles in mind, so it's not like longer braking distances haven't been planned for.
P.S. Don't forget to adjust your damned brakes. They do wear down.
Would of been a better comparison if both tractor units used the same trailer
no because the trailers also improved over time and they belong into the test of new technology vs old
Plot twist: the old truck still has its original tires

Truck drivers sometimes think that they are driving a small vehicle, they forget that it requires more distance to brake, that's why so many accidents, specially here in Mexico where I live.
41m is only a couple of meters more then a car which would be around 37-38m. and that with 38.5t of load. people think that these things cant brake when they can brake almost as fast as cars at that speed
@@sgxbot I am talking about Mexico... There are almost no new trucks, most of them are ten or more years old, and they get almost no maintenance. They are only repaired when they break down... That's why it's so dangerous.
I still prefer the old one
To all the people saying switch trailer, switch drivers, switch gender, switch planets for variance of gravitational anomalies.
I am certain the company didn't just wing the video in 1 minute and 12 seconds and that was all the effort put into it.
They wanted to make a statement about safety and how future technology has improved it. They made their point, there didn't
have to be a 45 minute in depth video. I think we can all believe technology on trucks has improved. They just gave us a simple example.
I mean if this is a conspiracy then who cares, more than likely when it counts the roads are icy anyways.

Next to the brakes the tires are very important, too. New tires on the old merc and again!
@@kstudios8706 the old one only half braked. older trucks dont have the safety systems newer ones do so fully locked brakes are actually fully locked and could stop way sooner then a newer truck but more violently and alot higher risk
Wszystko fajnie, tylko że "stara" ciężarówka to model który w produkcji znajdował się od 1989 roku. Bardziej uczciwie byłoby porównać z pierwszą generacją Actrosa, która do produkcji weszła w 1996 roku, a więc w 1997 była modelem nowoczesnym, a nie konstrukcją ośmioletnią.
Sidenote... The modern one with the ABS started slipping and it kinda got out of the straight line. The Older model with drumbrakes... Remained stable....and in a straight line...
I know which one id choose... The old Model all day every day. The romance of trucking is oldschool... The Modern thing is automated to big boredom.

Oh, I'm sure you will *feel* when you will collide with an obstacle at 43km\h, while the new truck will scratch a bumper.
I don‘t get why people think this is a set up. Why are you surprised that a older truck without modern abs and esp and with older disc or even drum brakes has a longer braking distance than a modern one? They chose a closed trailer because that was the one they had at hand. It is clearly stated in the video that they both weigh in the same. Again, why should the have set this up. The DEKRA is an wourldwide operating audit company which is also allowed to take the mandatory technical exam for passenger cars in Germany.
These tests are always Manipulated to suit the Desired outcome .
Of course the New tech is Better that I’m not disputing , but what is the Condition of the Brakes on the Old model?
Yep the driver was told your bonus depends on you letting the newer truck win......ok boss no problem.
@@bertiewooster3326
Exactly Too many variables , what about the Condition of the tyres ? The weight of the Trailer ? Driver reaction? Quite a few things to consider
...obviously someone doesn't know the trucks length, the difference is only 16m, but the length of a standard truck is nearly 19m so how come the older truck is so much ahead, I think the lenght difference should be about 23-24m if you judge by the Video...

Nope, 13. 6 trailer, with 2 to 3 metres of cab.

Yet, these trucks are still killing machines.
Imagine the brake screeching on the old one
The old design is still better
yup
Who else with even basic vehicle knowledge noticed the guy in the older truck wasn't even trying to stop fast older trucks don't have abs so have a quicker skidding stop but that puts more wear and tear on the truck thats why they aded abs to save people money since the truck in this video didn't drag even a single tire but the new truck did either the breaks are faulty and don't work so the vid isn't a good even comparison or they did it on purpose to pretend newer trucks are better at stopping also the kind of tire has a huge impact on how fast a vehicle can stop so of course they left that out
Der Unterschied zwischen Trommel und Scheibenbremse.
Aber es geht nichts über den SK.
Allein schon der V8 Sound. Einfach Ein Traum.
This probably has more to do with disc vs drum brakes and condition of the braking system on the older truck. Put all new brake linings, drums, slack adjusters, s-cams, and then do the test
Why? The idea of the test is to provide a visualization of the myth than modern trucks are worse than the older ones.
They should show us the weights on new truck too.
Why? If they wanted to cheat the test, they would cheat it in a different way. And if you want to suspect them in cheating, you'd find other reasons to do so.

Yeah but what's inside the other trailer...... why would it be covered
I like the brevity of this video, but they didn't say anything about *_how_* this much-improved braking distance was achieved.
i would asume improvements in the anti lock system. keeping the tire at the optimal slip point where you have max brake performance and not just increasing brake pressure until lockup and then releasing it a bit to get the tire rolling again as it used to be.
@@sgxbot I think so too. Brakepads itself are probably at their prime for years (if not: decades) already and can't be improved anymore.

Just curious about this test as the trailer brakes also has a huge impact in fact the brakes of the trailer caries the load of what's within it the trucks brakes allows for both to come to a controlled stop ...

41 meters to full stop a loaded truck, just AWESOME
The new truck had smoke from the braking wheels ect. the old one did not, seems odd. how old were the brake pads on the old truck?
looks sus to me, like the old one wasn't braking as hard as it could
Because the brakes on the old truck is just much worse and doesnt brake as hard, thats why there isnt any smoke, not hard to understand, the old truck just performaned bad due to its inferior technology in brakes and braking system. They are trying to show the difference in the new vs old technology and brakes and brakes should behave the same even if they arent new as long as they isnt completly worn out.

@@freevideos051 I highly doubt they are worn out, were do people get that impression, you do know what worn out means right?

Wtf i don't know 😭😭😭😭😭😭😭
I noticed that the Difference should be 20m approximately
There’s a difference between a 20 year old truck and a 20 year old truck with 20 year old brake pads. Truck break technology hasn’t changed much in 20 years, the only difference is ABS really
it has gotten a lot better. back then the abs would lock up and unlock the tire multiple times per second. today the tires dont even lock up anymore when above 5 kmh or something like that.
@@sgxbot That most likely has more to do to with high speed electronics than anything else: when ABS works its magic, huge, HUGE currents flow through the electrical system as it tries to regulate braking power as good as possible. Besides a possible 'arm system for impact' (deploy airbags), this is the sole reason the audiosystem in a car can stop working when doing an emergency stop (did such a stop on purpose once on an empty motorway, doing 80 km/h (had just sped up coming from the slip road, and the sound system immediately stopped working as soon as I fully braked).
Electronics have improved so significantly in speed, efficiency and such that the computers are now far faster and (thus) far more able to keep the wheels from temporarily locking up. If the same ABS system would be fitted on the newer truck, it would have the same outcome as on the old truck.
@@weeardguy that actually has not much to do with the faster electronics because its the sensors that are required to detect the amount of slippage etc that hasnt been around back then.
I wonder, why does the new truck have a closed box? Why they didnt show the cargo in the trailer?
Is it because its an empty box?
Put flat beds on both and i will believe it!
For now its just fake for me!
Dont look fake. The new truck brakes harder by the look.
you are nit picking, its really stupid to belive that 20 years older truck will have the same brake power as a new model
It don't matter if there's a load or not. With a load you have more pressure on the tires, without the truck has less pressure, but also less weight. The brakes are made for the loaded truck, and the truck adjusts the brake force depending on the actual load.
This has nothing to do with a passenger car.
@@simonm1447 More weight will mean longer braking distance.
Just because you have more weight on the tires, and therefore more grip, it is NOT equivalent to simply having less weight.
@@reinbeers5322 I know it sounds strange, but an empty truck will really don't stop with a shorter brake distance than a fully loaded one. Brakes of semi trucks and their trailers are designed for full load, they can absorb the heat of an emergency braking maneuver. With a fully loaded trailer you have much more friction on the road, so the brakes can work with 100%, if the truck is empty they can't and work with less braking power. Modern trucks with air suspension calculate this with the acceleration (how fast it accelerates if it's leveled, they have a tilt sensor in the truck), older ones have a simple device which measures the suspension travel of the leaf springs.
shannonlawgroup.com/calculating-stopping-distance-semi-trucks/
BTW, I had a education at Daimler when we picked up our new truck, and they told the same
Having driven both generations of this truck the test is very valid, whining about showing the inside of the curtain, and swapping trailers.......anyone who has driven both generations will attest how much better the braking is in the newer trucks. Dekra is one of the few independent organisations I actually trust.
Rather suspect a lot of these comments are coming from wannabe truck drivers from ETS2 !!!!
The driver in the old truck should have pump and release the brake multiple times, then it would have stopped more efficiently
Why would he do that if the wheels never locked up?
nice brake test video :)
volvo be like: cute ... i can do it within 10 meters
Makes me think why they haven't got the same trailer
Because this trailer didn't exist around the time of the old trailer (thus it's impossible to pair these because it wil make it unfair due to the combination of old and new).
I think the purpouse of this test is to show how stupid the regulations about speedlimits on german overland streets are. They were founded when those old trucks were around, and were never updated to justify the advancements. Back then 60km/h was alright, but now 70 or 80 would be alright too.
I take SK, thanks!
people still whine how everything was better in the 80s and 90s
Lots of things were better in the 80s and 90s!!!! Truck brakes are clearly not one of them!!!
Would like to see sale test with same semi for braking performance of loaded semi and really diff on tractor.
Must be less huge even bot changing the evolution
How would they compare empty? Would a modern truck and fully loaded trailer need much more distance to stop than if it was unladen?
Did you put new brake pads and rotors on each truck, why didn’t both use similar trailers to make the experiment more accurate, where both truck the same class?
The purpose was to versus old and new, not old+new vs new+new. I think they wanted to show how stupid current speedlimits are on german roads are, because they were made back when trucks needed 20-30m more braking distance.
I love the older model nevertheless.
OMG, all those dumb comments. "If they would use the same trailer, and the same tires, and the same brakes and and and and.... the same components, so the old truck is equiped with all new tech it would have the same distance, duh". Again: The point is to test 2 vehicles of two different eras with their current technology and not new vs old with all new parts.
Having driven numerous different Merc Actros's I have to say they model in this video has terrible brakes. DPD use them, and apparently use genuine Merc brake pads, (I asked a mechanic whilst working there). You press the pedal and initially it feels good, but then feel like its not going to stop. The older Actros (Euro 5) the brakes felt great. I wouldn't like to drive that old banger of a truck in this video though, having just watched it trying to stop.

What tyres were they using, had they both been recently serviced etc. Useless "experiment" unless you include all the details.
This is why the highway code is balls
The older model uses drum brakes, instead of newer model using disc brakes
The new trailer started breaking before, and the loading is diferent besides the old truck with those brakes wouldn't be steet legal.
I don't think this test is valid.
Why not testing with the same trailer on both semis??
this is vehicle
Because the title say old vs new and not old+new vs new+new. Why would you test it with a new trailer if you want to show the difference of 2 eras?
@@florichi thats a good point.
SK is best ❤️
yes
We want the test with new brakes for both of the truks.......
What about same material linings, same driver in cockpit?
In fact we didn´t see the concrete blocks behind new truck. The trailer could be empty. So it could be fake. Which means very bad job from DEKRA.
Race between old man and his son
Were the brakes properly adjusted on the older model? Did both trucks have disk brakes or only the newer one?
@juncukk, why? Did my comment make too much sense? I drove my first truck in 1975 on Ft. Benning, GA, and obtained my Commercial Drivers License in 1991, medically retired in 2018 and have driven a truck of some sort in three different countries so excuse me if I seem too knowledgeable.
My step dad works for dekra as a vehicle inspection service to see if its road worthy/legal
Hamis teszt,valótlan összehasonlìtàs.Hol vannak a guminyomok,a füst?És a 20 éves Merci miért menne 80km/h val,abban az időben lassabban normàlisan közlekedtek
Surprise - Surprise. A 20 years younger lorry breakes better than the old one. Really, what a surprise....
I dont think the driver with the cement block is too keen on hard breaking, those block tend to keep moving and cruch em cab. There are such things as an object in motion stays in motion with the same speed and in the same direction.
he braked hard. you could even see the abs work on the old truck. it just couldnt brake harder with the old system
1:02 who else thought the truck would jump out of the screen and hit you so you got out of the way
