It would be absolutely awesome if you would do a video about the Class 1 DTM cars as theses were one of the last uninfluenced ones by BoP.
And they were fast asf almost lmh/lmdh pace and quicker than lmp2
Or better yet, GT500. Those cars are even faster than DTMs, are also not regulated by BoP (though I dunno if they still have the success ballast), and still exist today.
The history of the DTM as a series and the development of the cars
Loved those DTM cars bespoke carbon bodies so light so much downforce race more like single seaters but also expensive in the end why the started using GT3 cars now in DTM sadly don’t like them as much
@@epitosu6461they do have success ballast based on point standings (*2 for GT500, *3 for GT300)
I'd love a video similar to this comparing the GT3 and GTE, what makes them different and what makes the GTE faster and why the cars can't compete in both
Great suggestion.
On the other hand, Super GT's (the Japanese racing series, not the UA-camr) GT300 class can match and, often, post faster times than GTE.
It is (or now used to be) that GTEs had way more developed aero, but current GT3 gen is, almost has, caught up to that. They also featured a better suspension as far as I know.
i just commented the same thing even before reading your comment 😅
@@TheGamingHungaryyeah GTE underbody aero was more efficient too. They had less drag than GT3 cars aswell. But I also rememner hearing the tires they used was of a higher grade with more grip🤔
M4 also has 4 seats like the 911, and the New Mustang is a 2+2, RCF is a 2+2 as well, plus the GTR although it’s showing it’s age
296 GT3 is my favorite right now. It used to be the 488, but the 296 seems to have improved on it in virtually every way. I really like how they handle and I find they are very balanced overall.
I love that smiling front grill of 488 gte/gt3, such a good looker.
The 296 race car is so Sexy especially in the way it is fabricated.
GT3 really has come a long way since 2006. Especially when you take Porsche's first GT3 car, which was just their cup car, and compare it with their current GT3 car. its a completely different animal.
I'm a Porsche fanatic with their GT3R but I believe the best all around GT3 car till today is still the Mercedes AMG GT3. Seems approachable to the less experienced, reliable, robust, fast, easily repairable and one helluva looker too.
I have never especially liked the Merc but having been to last weekend’s DTM race I gotta say it’s also the best sounding car in the series by a fair margin!
@@wiegraf9009 sounds like an angry machine yes
@@christianb.4385 To me it actually sounded a bit more musical than the angry roars and buzzes of the other cars. Had a clear note to it.
@@wiegraf9009well it uses the 6.2 NA V8 which is one of the best sounding road car engines
Yeah you can always tell when their are feilds of em in GT3 championships around the world. The AMG evo I think is still the META irl as you said it's more approachable. The 296 maybe the better race car as of now. But the AMG evo seems to be way more accessible.
I'd say before the AMG evo the metal may have been the 488, and before that the R8 LMS ultra before 2015 globally anyway.
Don’t see it as often but I love the look of the 720S GT3
Watch GTWORLDCHEU Race
How come we don't see it much? Is it just really expensive or not that fast?
@@bonifacelukosi9580Pretty much
I love how so many of the things mentioned that make a good GT3 car, the BMW M4 contradicts:
Big frontal area
Taller center of gravity
4 seater base car
Asymmetric thermal distribution (both turbos and whole exhaust system on the passenger side of the car)
Pretty effective car nonetheless!
BoP
Only due to BOP without BOP front Engined car would be slower than Mid and Rear one
@@fqeagles21 no GT3 cars are designed to run without BOP, BOP is the whole point of the ruleset
@@Milano322 I know that’s why the M4 could be competitive,without it not a chance
I'm so excited for the Mustang next year 😎
My favorite is actually the M4 GT3. Wasn’t convinced at the launch early last year - but it turned out to be very competitive.
Thanks! I found a difficulty while build mine. It's such a great help🙏🙏
My favourite GT3 is the Honda NSX. I wish it was ran by more teams in Europe.
Great video but I feel you missed one other key component which is factory support. Mercedes and Audi for the last few years have heavily dominated grids in terms on number of cars and I think a big reason for that is factory support.
Audi? Dominating? The last few years?
Are you smoking crack?
Audi dropped to two cars in 2021 in imsa because they were pulling back support. They had no logistical support in 2022/2023 leading to WRT going to BMW. 2024 will have them kill their program (their words).
Thats 3 years of no support and very little cars in the north american market. The image is the same in europe.
corvette c5, c6, c7 has always been my favorite. The GOATs. he he
close second is the AMG, Z4, Bentley and any other FMR Car. with a big angry V8.
Great video! I just found your channel and instantly subscribed after this one. Thank you. I hope to see a good performance from BMW in GT3 soon...
Thanks for the sub!
Great video!! It would be interesting to continue with this as a small series. I would love to learn more about GT3 in this manner. Maybe you can make a video about how to get to work in a GT3 project, from a manufacturer.
I am often very oblivious, even naive, with the finances and economics of everything. I apreciated this. It was very insightful. My favourite gt3 car is the 911 because of the sound. Thanks for the video!
Solid points about what customers want.
I miss the Z4 GT3, it was a beast. feast for the senses
One of the best sounding GT cars for shure, you could make out the sound between a whole group of cars on track.
Nice, I was hoping for something like this. Always wondered just how much a GT3 is able to tow the line of being a GT racer instead of a silhouette prototype.
Great Video mate!
Great video! Very insightful.
Excelent video !
Quality as always
Nice video. Would love. Know more about exactly who the customer is, and the business / logistics side of things.
Always fun talking about race cars right!?! R8 LMS GT3R and 720 are my favorites. 296 and NSX are great as well. As much as I love lotus I’m glad they didn’t try to build an Evora GT3. It probably would have went even worse than the GTE version 😅
I loved the old Nissan GT3, also ghe Jaguar with Emil Frey back in the Blancpain era. Strange cars with nice look
It's nice to hear an engineer from motorsports actually describe these sort of things. I've always wondered the same thing.
That silver Audi R8 and the end is pretty nice!! But some of those Porsches are mental.!!
my favorite class of racing car in ACC and Forza Motorsport!
Are you able to explain the rules and regulations of GT3 in another video?
Great video! I’m by no means a fan of this brand, but did you omit the Aston Martin Vantage GT3 by choice or…?
Callaway Corvette 😍
Nice and easy to digest information about GT3! Can you cover similar GT3 class in Japan, dubbed "JAF GT" and Mother Chassis? Kinda curious how they compete in other GT3 championships
JAF GT300s (and MCs) are nothing like GT3s lmao.
@@kartaltoth684 I know2. But it's nice to know racing cars that can compete with GT3 spec cars
I remember looking up close at the first gen GTR Nismo (2014-15). It was surprisingly similiar to the road car from the interior layout, suspension setup and engine design/placement. Now, GT3 cars are extremely complex (especially aero) and aren't a good representation of their road counterparts anymore. They're faster and the racing is better but its a shame they're more expensive and almost too difficult to work on for amatuer teams.
Ferrari 296 street version is probably faster than GT3 un traction and straightline
Want more stuff like this
@bsport what is the eligibility to enter? Minimum production number?
It would be awesome if you do the analysis for GT500 at superGT, they have more aero i think than GT3, and more HP, perhaps different packaging? Or only tuned more? Thanks, you're awesome man
GT500 are totally different. They are not related to their road car equivalents at all. They shared regulations with DTM until it collapsed (again) and these are silhouette prototypes with bespoke racing chassis and turbocharged i4s (previously NA V8s) dressed under body vaguely similar to the road car.
Could you do one of these on the gt500 cars in super gt? Fastest touring cars it seems - almost formula like. What makes them different from GT3/GT300?
Thank you!
It would be awesome if you can do same about lmp3 car. my dream is to build lmp3 car styled racecar at my garage
Can anyone tell a little bit about the pneumatic jacks that these cars have built in them? I'm also curious how much that system weighs, and is it used in all racing catagories? Or only in endurance?
It's quite a standard system in racing. You weld in 3 or 4 tubes into the body, fix the pneumatic cylinders and connect them to the external connector.
When the car comes in, you connect the pressure bottle to the car and the jacks go down.
If you release the bottle, the jacks go back in.
@@BSport320 Thanks for the reply. It also seems it weighs just about a kg and a half for each corner. Less than I expected.
ua-cam.com/video/I8ofkIzft-s/v-deo.html Good information here. It’s V8 Supercars but the systems are similar worldwide.
The AMGs are NA but they are still doing very good and achieving many wins in Big events, could it be that its a really torky one?
Nice video, helps explain why there's more to a good GT car than just good/bad BoP. Which would you say are the best and worst overall GT3s currently racing? Non-expert opinion but the AMG GT seems like the most complete package these past few years (used to be the R8).
this is really hard to tell for us as non participants because there a lot that factors that we don't know about or information is hard to come by. Like costs, support and quirks of the cars. stuff like AMG not having auto engine ignition once it drops from the jacks so it often loses like second or two in the pits(commentators on paul ricard race mention it few times). How hard or easy it is to work on cars, how hard it is to set up maybe it is great car for pro team and pain for others. I always try to keep all that in mind and the fact that thing are changing from year to year, like the fact that audi is no longer supported, it had nothing to do with cars performance.
Then you have to take into account stuff like that certain cars have cups like super trofeo, Porsche whichs makes them ideal packages for teams coming from those etc
@@MarkoLomovic Yeah, it's true that there are a lot of factors beyond pure speed. BoP means teams have to focus on a lot of these details which can make a difference. Support is an interesting factor, WRT leaving Audi for BMW seemed like a big turning point in GTWC, the R8 is still competitive but has taken a small step backward. Can't wait for Spa this weekend!
@@aojracing4885 it is not that WRT left audi and more with the fact that audi left GT for F1. if I remember correctly they had to scramble fast to find new partnership because they want to have stable platform for foreseeable future. it is better to get new car right away and start learning and improving then have another season with car that is not going to be supported any longer.
by 2026 we will have hurracan replacement, new AMG, Ferrari is going to get developed further etc while audi is just gone.
Support is interesting factor and not only in equipment and cars but also in data, knowledge and training etc
You can imagine that what for example audi learns from all the teams can be shared around. Even small stuff like car operations.
Can you do lmp or hyper car ?
What parts of a GT3 are actually shared with a road car? Thank you.
Not an expert but it depends, it's said that only ~40-60% of road car parts are shared with the GT3 model, generally the chassis engine/block and drivetrain layout. As explained in the video, there were cars like the Z4 GT3 and Bentley Contentinental GT that shared very little with the road car and cars like the R8 LMS and 911 GT3R being an example of how manufacturers marketing their road cars as very similar to other race version.
I know the engine on the Ferrari 296 GT3 is the same as the road car and also the same thats in the 499p hypercar.
296. Like the awesome technology
can you do how to build a lmh/lmdh car next pls?
my favourite gt3 car? All of them!
Gt3 is how racing should be!
If people are honest who really wants single seater or middle managers company car racing.
It makes me laugh when you see that VW Group Coolant Tank on everything they make 😂
It's simply a very good design for all their requirements. It's a spherical shape, which allows smallest volume, lowest weight and reliability.
Maybe expansion bottle design is good stuff for a future video.
you're talking about GT3 but you showed the Corvette that is actually a GTE, why don't you do a video about the differences between GT3 and GTE? (even if next year GTE will disappear from racing in WEC)
Keep in mind, the IMSA C8.R is currently running in GTD Pro (basically professional GT3). Not entirely wrong, but yeah, a different picture works better.
Do you have a link to the documents showing what has to be kept from the original car? And the real differences between GTE and GT3 regs?
All I know is that GTE cars are built for racing and have more aero freedom than GT3 cars. As for GT3 I think the chassis has to come from the road car
@@m3lgar582 but Ferrari offer a kit that can change a 488 GTE to GT3 spec and vice versa. So it's not that fundamental.
@@Scotracer1987 Thats true. But only applies for Ferrari and Aston Martin that run the same cars Vantage and 488 in both categories (although not for Ferrari anymore). The exception is Porsche and Corvette. And even for next year Corvette aren't converting there C8.R into a GT3 and just making a new car entirely based on the Z06 of course putting there GTE experience into there new GT3 car
After this vid, I'm now wondering which GT3 car is the most common and which one is the most rare.
I assume Merc and Porsche are the most common because they provide the best support and their cars are thoroughly tested on tracks that host crown jewel races like the 24hrs of nurburgring and 12hrs of Sebring
As for rarest its probably either the Bentley Continental or the Corvette C7 for reasons such as complexity, lack of support or an outdated car.
Ive heard merc is pretty good with the handling and throttle too, also bothe Merc and porsche do look like they have great pace
Mercedes and Audi are easily the most common. Audi is probably more common in Europe compared to Mercedes but they have no factory support in America so no one runs them there.
There are a lot of old GT3s that haven't been used in ages, so it's basically impossible to determine what the rarest GT3 is. My guess would be the Emil Frey Jaguar G3 because there were only 2 of them ever built, but it's not an FIA homologated car which means it's technically not even a GT3.
My favourite is still the Nissan GTR gt3, but they do not seem to be competitive anymore.
The GT-R is still competitive in Super GT and Super Taikyu. Unfortunately, it's rarely used outside of Japan anymore.
@@albert_gyorgy yeah man so sad
@@JoshuaC923 It's sad indeed, but not unexpected. The R35 is 15 years old and even the GT3 version is more than 12 years old by now. It did get a lot of upgrades, but that doesn't make the base any newer. I do have a slight hope though, since they might update the GT3 after the road car's facelift.
@@albert_gyorgy agreed, fingers crossed!
6:45 what's this air lift sistem? Does the car have integral air jacks to ease tire changes?
Yes exactly that. Each car has 3-4 air jacks integrated in the car, so they can quickly lift it during pit stop. They use an external pressure bottle which has a connector somewhere at the car.
@@BSport320 Cool
kinda weird how literally no one made a video on corvette’s gte win this year at le mans
Wow what was that c7 corvette?
M4 🔥
I'd say Lambo, even though I'm not a fan, but only because of the V10. Otherwise AMR Vantage, just don't like the look of the AMG GT.
With Audi now sadly closing down much of it's GT3 Programmm, do you think that potentially instead of the Audi R8 as a GT3 basis it would have been possible for Audi to use the RS7 instead?
I think the RS7 wouldn't be a good basis. It's basically the same issue as what the BMW M6, Bentley Continental had (with Bentley using the Audi platform).
So it's much too big, heavy and the engine is in the wrong position.
Also the RS7 body creates far too much lift, which would have to be compensated by bigger wings, resulting in higher drag
What do You mean by "symetric engine" at 5:07?
I mean intake and exhausts are symmetric.
So either an exhaust either side and intake in the middle.
Or hot stuff in the centre and an intake either side.
Asymmetric would be an inline engine with intake on one side and exhaust on the other.
@@BSport320
Thanks, now its clear!
Agree on that!
Corvette Racing!
Can you make the a video about Super GT? Probably the fastest touring car now
I believe they are in fact the fastest prototype/silouette around. With the retirement of the LMP1s, being faster than the LMHs they are at the top.
@@lw8249 as mentioned GT500s are Silhouettes pretending to be GTs (not Touring cars). Pace wise they were faster than LMH last year though I'd expect this year to be equal with CNF losing 500s about a second and LMHs BoP no longer being based around Glick's pathetic attempt of a car.
How is the MB a low frontal area - just a bluff lump! 😀
Low frontal area
Bentley continental GT incoming 😎
Huracan gt3 looks awsome.
talk about exige gt3?
How about the 1995 Mclaren f1 gtr-bmw?🤔💪🔥🤑
Do they absolutely need to be rwd? Or would we see something like a civic in the future?
They must be RWD
you would have a really hard time building fwd car to the GT3 level. fwd are hardly limited in perfomance, touring class is the best you got
@@maximborodyuk3773 this is of course not mentioning Ratel would throw you out for suggesting that. The upcoming Mustang already annoyed him to no end and he would've stopped it on it's tracks had he learned of it in time. He doesn't want "cheap" cars like the Mustang.
And on the topic of the Civic, Honda is building a GT500 spec to replace the NSX. While not FWD it will be a comical thing as GT500s were faster than Hypercars last year around Fuji by a margin.
@@kartaltoth684 you making shit up as you talk lol
It doesnt matter what he personally wants and I don't think person of his position would be thinking in this categories. There is a regulations and cars being built by them.
There is BMW M4 GT3 (and other models previously) that is exactly in the same class with Mustang (comparing road going versions). And they're in GT3 class for years.
Also, all GT3 cars priced more or less similarly, comparing their road going counterparts are kinda dumb.
Mine is the Dodge Camry.
my fav is Bentley.. :)
The BMW M4 GT3 is a great car ??
1:52
Audi R8 ❤️
Ford Mustang V8 GT3💪
my fav is the mclaren 720s
Turbo engines are also better at higher elevations.
500 hp is the sweet spot
Of course Bentley. The best sounding GT3 that existed
Will hybrid GT3 cars ever be a thing?
Probably the cost of maintaining the hybrid components is the barrier, more so for privateers.
@@pmayo7894 I don't think the hybrid system needs to he maintained all that much. I believe it's more just the sheer cost of the hybrid system, it would make the cars much more expensive and the drivers would need to learn how to use it. That means higher costs for privateers and less sales for the manufacturers. So it wouldn't really be beneficial for anyone.
Eventually... Populism will make it the only option to have any ICE racing.
Do you think we'll start seeing GT3 cars with 4-cylinder engines soon?
Current gen 4 cly engines are topping out at 2- 2.4 liters. With the 500 HP reference we are talking of 200/250 hp/litre, ain't gonna be cheap make it reliable for endurance
Only if it's a hybrid.
I don't think that v10s have issues with torque against new turbo charged engines. over past years that was pretty much proven at this point.
Doesn't BMW have an M4 GT3?

Is it possible for Subaru to make a GT3 car based on their Super GT 300 car?
@@albert_gyorgy - I'll need to correct: the BRZ GT300 is a JAF-GT300-spec car not Mother Chassis. It's easy to tell since the latter always use a GTA-branded Nissan V8.
@@pmayo7894 I'm sorry for spreading misinformation
@@albert_gyorgy - don't worry, not a lot people understandably has a hard time differentiating a JAF-GT300 car from one made under the Mother Chassis specs. The prior comment should help them short-term.
@@pmayo7894 I was wondering and I even searched it up and an article mentioned it as a mother chassis car (or I misunderstood something).
@@albert_gyorgy - three specs are available for GT300: the FIA GT3, JAF-GT300 (which the Subaru uses), and Mother Chassis (the ones where they always use the Nissan V8s). The BRZ uses the EJ20, so it's a JAF-GT300 car.

"how to build a GT3 car"
*shows a GTE car on the thumbnail
Not entirely wrong given that Corvette had to mod (tone down) it in order to compete in basically GT3 (GTD Pro) in IMSA.
Bmw is the only brand that has 2 different models racing in gt3 what u talkin bout? Both the m4 comp and the z4 is in there
i love the fact that the ferrari has sold every gt3 car that was planed to build this 2 years
The C8.R in the thumbnail is a GTE car. Not a great start.
deutscher accent in ersten 10 sekunden gespotted 👀👀
Then Nissan GTR was banned by FIA because its AWD right
No.
Regulations mandate that the GT-R be converted to rear-wheel drive in order to compete. Same with the Honda/Acura NSX (it also has to ditch the hybrid system). The main issue is that the GT-R is already uncompetitive in almost all racing series execpt Japan's Super GT and Super Taikyu.
Mustang GT3 is not going to be competitive imho. Hope I'm wrong it'll sound cool
Why?
@@agontprevarator5214 Huge frontal area/drag like the Bentley.
Well that's what I've thought of BMW, but keep in mind the BOP - they are way stronger this year. Still, AMG will win...
@@justinerickson7237 Well the Bentley won Bathurst, so it was somewhat competitive I'd say.
Useless vid, author doesn`t know that power=torque*revs, so having 500hp you have the similar torque on wheels, no matter what you have on flywheel, transmission ratio will equalise it
