This is Amazing!
Excellent explanation guys 👌
Finally! A Front Wheel Drive Mercedes Benz! Well, most of the time :-)
Very nice presentation
You definitely won't mistake this for an active torque splitting diff like that found on the now-departed Lancer Evolution or Audi S4 (with sport diff).
However this system is more intricate than the Focus RS 'revoknuckle' and GM's HiPer strut to try to rid the torque-steer in high-powered FWD-based vehicles. As a side benefit the standard AWD does help immensely for those who live in the snow-belt (you try driving a RWD M3 or C63 in 5in of snow).
I like this new improvement.
Mercedes
Love my a45 amg
Good video
nice car crossover
1:20 looks so cool
Nice
Whats the name of the background music? :)
l love Mercedes its the "Best or nothing".
One of my friends owns a A45 AMG he said that the turbo is fairly laggy an that they only really shine in corners
What about old Mercedes 4matic systems like a 2003 model
Lol he said "sheer driving pleasure", the BMW slogan
Ha, ha, renault-nissan collaboration is to be seen on mercedes :) koleos, qashqai and dacia duster have the same system. Indeed new design and cutting edge technology :)
good jop
There was a time manufacturers used to design it's own components, due to cost constrains not sure if this 4matic system isn't actually outsourced and only somewhat tuned by Mercedes-AMG.
Haldex, Borg-Warner, and Aisin make most of the AWD systems (and transmissions) these days
This is very impressive and I'm glad that as a species humans have developed such excellent engineering marvels. But it's much more effective to put an electric motor on each wheel and control them all with software. Batteries are the main problem at the moment, but we'll get there soon.
meh, electric cars are boring and not practical at all
Amazing!!!! No one can beat german's machanic,they made the best of the best,this is why theire cars are the best un the world
Unfortunately you are totally wrong. This transmission has an inherent and well documented failure - loud crunch when engaging reverse. Poor design. Sorry
This is one of those cars that are actually safer and better handling, predictable with ESP off -- most of the time, at least.
If ESP is on, and I've been driving a grey A45 for almost a year now, the car is just to heavy in the front, and almost always understeer to da dangerous level, really (also making you look like a ridiculously bad driver).
If you're a more experienced driver, you turn ESP off so it won't intervene. ESP actually, in most cars (except for for "sport mode", or equivalent, on RWD only cars) should be turned off if you're more experienced, since then the car will be more predictable and - in the right hands - actually safer. I know and seen AWD drive cars get into some accidents because of understeer caused by ESP intervention trying to brake the front wheels (even rear wheels, depending on how said AWD and ESP system works) on slippery conditions and making the car slide foreword.
Even then: at high speeds, the A45 is still prone to understeer a fair bit.
hi, how do I tell if a cla250 is a fwd or 4matic except looking at the badge?
Look under the rear of the car to see if there's a diff.
Is it same as Audi Quattro principle ???
wish you could set it to rear wheel drive only :( much more fun
R o n n o c Who would’ve thought that 5 years later this would be available... The new A45 has drift mode so you can set all power to the rear wheels.
@@staticjet Oh wow.. Go drive an evo with a proper centre diff and yaw diff which was doin this 20 years ago!
A bit late but buy yourself the 2022rs3 you can choose rwd 😉
@@LB83. hahaha woweee. Well at least the new RS3/A45 have drift mode now lol ended up getting myself a WRX STI in the mean time 😛
2:15 rear end is deprived of power? Probably makes for a very weird situation if you are a more experienced driver hoping to use the rear wheels to get you out of trouble...?
DJ BIS and the constant change in traction/behavior must be something to get used to as well.
If you're a more experienced driver, you turn ESP off so it won't intervene.

If you are a more experienced driver and you're reaching the edge of adhesion on the road then you are an idiot!!!
My only LOVE----- MERCEDES
🤢
and why is my CLA45 got the clunking sounds from the rear differential? as if i bring a tons of watermelon inside my trunk!
yup common issue....bad design...my last Mercedes tbh
Change your rear diff fluid every 10-20k miles it’s so easy to do
TOD - Torque on demand.
Same as Haldex
0:58 What it is? please answer somebody
the drive shaft always connected to the rear to take up to 50% of the torque to rear, but the drive shaft is disconnected to the rear wheel with clutch plates. when press those plates together, it can connect the rear axial to the drive shaft to make rear wheel turn. In this case it is a basic connect and disconnect like a light switch. For the power that send to the rear, that will depending on how the gearbox do. because it has to connect to the front all the time, the transfer power to the rear seems to be leeching to the front through simple gears. That is why it cannot detach the front to make it rwd. The other way to do it is to put the same system to the front axial as the rear and become a transfer case so that the car can send more power to rear. However, this way will require a much better and stronger gear in the back (cost and space for smallcar usually cannot allow that) and therefore like the focus RS would only allow 60% to the rear since the rear gears are cheaper and flimsier. For rwd bias awd, u can check the A4.

Every info I have seen says the 4matic delivers up to 50% of engine power to the rear wheels when activated but this video says 100% of power can be delivered to rear wheels? Hmmmmm? Anyone know which is correct?
3Vimages it should be 50 % . Centre differential will lock front and rear wheels if full lock achieved it will be only maximum 50 % unless front wheels are under braking. 100 % of the power to transmit to rear on FWD based 4x4 is not possible.
New E63 is available in 4MATIC
This is FWD with Hang On Rear Axle not more then that
I did not understand any thing in this video but I know to go Mercedes only if you have lots of money, if a person of average income saves money to buy one of these then after 50-60k miles these cars can make him/her homeless
Is it possible to disactivate the 4matic for more fuel efficiency
2:31 .....
Tes drive yuk....
appena arriva lo stipendio me la compro......VaFF@@@u@o...........forse
the most safety car will be 4matic front wheel drive
Get a Subaru, Subaru delivers these all almost last 30 years already.
Subaru are just the toyotas on the boring version
So there's no difference...
well yeah but a m5 will get wrecked by a E63 AMG S-Model the damn thing goes 0-100 in 3.4!!! Thats lambe fast! In a family friendly car!!!!
IF U WANT PERFECT ADVERTISING MERCEDES IS BEST! IF U WANT REAL AWD BEST AWD WITHOUT ADVERTISING IS SUBARU !!
Drive an Evo X in snow and after that tell me what you think of this pseudo all wheel drive.
You left out the small details; The A45 & CLA45 weigh a scant 1550kg & will both easily crack 25mpg combined.
A Evo X weighs a hefty 1630kg despite being much less luxurious and a Evo X will struggle even 18mpg combined.
Sure these Mercedes MFA (FWD-based) platform cars will not hold a candle on a rally course or Auto-X, but are massively better commuters, blend right into a corporate parking lot & great occasional sporty drivers.
To each their own I'd say.
Trades46 I own an evo x MR, it is pig rich from factory, with boltons and tuning it gets better, I want to make a good track street hybrid car, not 100% dedicated track, but a trackable street car.
And I saw an Aussie comparison where the evo x used less fuel in a test compared to a Golf R that has direct injection, it was a surprize to me.
Trades46 The problem is that these "official" mpg ratings are produced under minimal load, it has nothing to do with reality, so when you hammer it no 300 hp car will produce anything close to 10 mpg, and they are advertized at 30+ mpg, that is at low load only, and we all know people don`t buy strong cars to go economically and slow, for that we have small engines and eco cars.

Sensible drivers will only hammer their cars on track-day or Auto-X. Sure you can occasionally punch it on freeway when Cops aren't looking, but it's rare enough that I can safely say most "performance machines" are only driven at the limit 10% of the time.
(If not so, I question your driving style & the validity of your license).
Let me put it this way; a STI & Evo would are better cars 10% of the time you're hammering them at the less-than-legal limit, but the Mercedes-AMG are better (more comfortable, luxurious etc.) when you drive them on the regular roads, 90% of the time.
And when you're NOT trying to get yourself a speeding ticket, then a 25MPG combined vs. a 18MPG combined would mean paying a visit to your local gas station each week vs. every 2 days.
I don't need a calculator to know how much petrol you'd save annually yet still have equal level of occasional fun.
Trades46 I have an economy car as a daily driver, when I use the evo for the go fast stuff, if the mercedes had the evo x awd system and a good transmission, I would buy that as a track toy, but since they don`t make cars hardcore anymore I will stick with the few that are left.
you forgot tones of understeer
On track, maybe. On public roads there is no such thing
JeromeDH92 isn't a corner on a track the same as a corner on the road?
TigR 5hark hahaha don't give up your day job.
TigR 5hark Your put downs are just like your jokes SHIT..!!!!
TigR 5hark guys just saying that a 4wd car that only oversteers on lift off its as fun as a fwd car .. almost all fwd hot hatches do this
Hahahaha, IN YOUR DREAMS!!! LOL
This transmission is not built to Mercedes-Benz quality standards! 48,000 miles on my CLA 45 transmission goes into limp mode. Update firmware! Will not complete adaptation no trans! At your motor car being told it needs a transmission! Control module is Warren teed up to 80,000 miles not even tested by the dealership! Code P0921 was given
Oh my, that's shocking. Did the dealer cover any fix cost? what happened to the car now. I am looking at the GLA45 now and seems like it has the similar issue with the Trans
Audi quattro
Aaaaaa! you said SHEER DRIVING PLEASURE?????
They still fucked up with the transmission clunk
let him... he needs to finish school first :)
AMG63 ? a C 63 is rwd
this AWD seems like an afterthought; an adaptation of a FWD... video is also misleading because only 50% of the power can be sent to the rear wheels in the A45/CLA45 AMG. I think they fudged around at 1:00 with the idea of "100% of that 50% can be sent to the rear differential by the rear electronic clutch"... not sure what they are trying to say but for sure this system can't function at a 100% rear torque split. Fancy presentation with big words... but at the end of the day just a traverse 4-pot set up with unequal front axles. Nowhere near a "perfected" AWD system. The 4-matic system is nowhere near the world-class AWDs from Audi and Subaru. It really irks me when everything sounds more believable with a video and a movie voice.
Its not misleading my friend. Its depend on the type and segment of car. For the A45 in the normal controlling conditions(cornering, acceleration or deceleration) it split up to 50/50. Check at 2:08 it send the 100% torque to the rear axle by applying brake at front axle during the lost of traction at front axle, that way they send 100% torque to rear wheel axle. Mercedes made this version for daily use sports car with good fuel economy, by keep it as a FWD in normal situation. It seems very reliable AWD system, because they use proportional valve instead of servo motor to control the plates
Abhir Malhotra The way how you communicate looks like you belong to a third world nation. Did you read my comment properly. Whats the different info that you are sharing rather than repeating same of mine
You are not the only one who spent money on your education. There are lots of people who are doing same thing. You spent on your self, there is nothing you have done for society that you are bragging about. By spending 30-40k on your study is not a big deal and there are tons of people spend more than you.
j dutt 30-40k?? lol. and why is it about society all of a sudden and not about my grammar or the country where i come from? lol
This AWD System is based off of the HALDEX ALL WHEEL DRIVE SYSTEM.
Even though m5 BEATES AMG 63 4MATIC
blah blah blah
Junk
copied from 4motion of small audis and vw
Wtf? Mercedes presented 4MATIC in 1986, VW used 4motion as name in 1999 and Audi have a quattro.
2bach The principle of operation is the same as VW 4motion. Copied from VW
2bach
And VW had produced it s own 4wd long before 4motion named syncro so...
he is right, this is basicly a mercedes version of haldex 4wd system and no it is not only a vw system, it is a pathen, volvo, ford, saab and vw all use the same haldex. This is because the cla is fwd based, any other 4matic benz have a different 4wd, more genuine and that is because the engine is not transversely mounted like in the cla, so in sum, almost every fwd based car has a very simular 4wd system to this.
piece of shit, 37k miles and the transfer box is gone. Need a whole NEW TRANSMISSION.
Absolutely shocking. How is it running now?
Copied from VW 4Motion
Same garbage as haldex !
Over engineered and completely unnecessary to spin a wheel!
👍🏻👍🏻👍🏻👍🏻
+bryan916 Then buy the same beautiful A class without 4matic. Sorted.
JUNK More problems
bullshit system its more like front will drive my cousin has CLA45 the feed back is weird rather get used SL then this shit
Mercedes? At high speeds the torque is sended to the front wheel drive? WTF! Quattro from Audi is way better, the torque is sended 40% front and 60% to the rear side
slow over priced.piece of crap.
