BMW M4 GT3 - In Depth Analysis

[@dylansmit3883]

The press release had the measurements of the M6 and M4 GT3 side by side. It's only slightly narrower than the old tank, but it's bigger in every other area. Crazy to think the midsize BMW is that large now.

[@devandrasimanjuntak1646]

honestly, this is a trend with almost every car in the market. It’s a very easy and cheap way to make a car more comfortable.

[@BSport320]

Yes, it's a general "side effect" but the M4 F82 was 60kg lighter than the previous one and this G82 is 200kg heavier than the F82. BMW has a weight issue not only with this model.

[@ivanbastos4963]

@@devandrasimanjuntak1646 Exatcly. That's why in rally, for example, the old C4 was replaced by the new C3, which are now basically the same size, while the new C4 is much bigger than before

[@G82_M]

Having owned a CS and now a G82 you wouldn’t think the G82 had a weigh issue. It’s so much faster, handles so much better and it hides its weight so well both on the road and on the track. It’s insane how much better it is.

Glad you like them!

[@GreasePanMan]

Absolutely crazy that the M4 is only 2 inches shorter than the M8

[@enzolibardi2679]

at the release of the m4 i found the front really hideous but now that im getting used to see it i think this new m4 gt3 gonna be a beast and i cant wait to see it on track

[@ivanbastos4963]

Unlike you, i still think it's an horrendous looking car

[@ApeRiderr]

@@ivanbastos4963 I think it looks good in every other way but the front end does not match the flow of the rest of the car.

[@johndeerman2105]

Excellent research and analysis. Thank you. ✌🙋🏻‍♂️

[@BSport320]

My pleasure!

[@Jarlefinken]

Great analysis of the car as always:). Hope to see more of these videos. Will be interesting to see this car on track, and hear the sound from the straight 6 as well. That is the most fascinating thing about the GT3 class I think, all the different engine and exhaust configurations makes it great to watch live.

[@BSport320]

Thank you very much!

[@ka-gt]

Everytime I am reminded, that the M6 GT3 will be gone I almost shed a tear. Its Sound while braking and downshifting warms my heart.

[@tydawidowski6245]

Awesome stuff I’m watching the M4 GT3 in it’s first race currently. Also people forget the M3 GT2 which was an amazing car and my personal favourite race car!!

[@lawrencepll76]

I think it will be a very strong endurance package like how BMW has usually done. Hopefully, it will have a lower running cost than the M6, so more teams can actually afford to run it. Speaking of new GT3 cars, I am quite impressed by how Audi's new R8 GT3 has a rear wing mounting, to improve rear wing's downforce. I am very fascinated to know if other manufacturers will copy them!

[@adityasingh-hf4zc]

Please don't stop making videos such as these, they are by far the best and the most informative ones out there that I've ever seen, so please please please don't stop making them. And ofc thank you, you're 🔥🔥🔥

[@mohammednawfalal-damluji686]

That's an intersting video 👍 As a fan of BMW and GT3 racing, I'm also excited to see a new competitor in the class. As a fan of the brand, I think I'm among the few who don't care if BMW doesn't introduce a proper sportscar platform, as they built their sporty reputation through sport saloons and through touring car racing, but in the case of GT3, it's showing that they did some extra work compared to other brands when preparing their platform to bring it as close as possible to the rest of the competing field, performance-wise, and despite that, the M6 GT3 wasn't the most versatile platform out there. It got close to win championships, but almost always, there was another car that was performing better. From what I can gather, based on some info that I either read or heard from different sources, is that among the problems of the M6 GT3 was its tyre consumption, which caused the car to lose grip and pace rather quickly compared to other platforms. Another thing is that the car's aerodynamic setup was most useful in high speed corners, which is why the car was at its best on the Nurburgring, as mentioned by a racing driver (I can't remember the name). I do hope that this new M4 will be more popular, succssful and competitive compared to the M6 with less compromises, because after all, it's still not a dedicated sportscsr platform. Finally, I have some questions: Among the interesting info on the video is the side exhaust system located on the front. Do you think it would be better if they ran the exhaust pipe under the right door to equalize the turbulence extraction, or would that introduce a greater compromise? And how bad this difference in turbulence release will affect the performance? Thanks 🙂

[@BSport320]

That is a really interesting thought! If they could manage to run the exhaust further to the back in the highest possible position, they could reach a much better extraction from the wheel arches (similar to DTM class 1 cars) which could benefit front downforce. The problem with that would be that in GT3 you have to stick to the stock body and positioning the exhaust in the middle of the door wouldn't be possible. If they would just run the exhaust underneath the right door to the back, it wouldn't change a lot because the obstruction of the vertical pipe behind the front wheel would be the same.

[@carfan8838]

You can watch the BTCC... BMW race their 330i's there and are very much successful

[@mohammednawfalal-damluji686]

@@carfan8838 Hi. I'm not exactly able to interpret your post on how it relates to what I said, but I have to say that BTCC is almost my most favourite racing series! I love touring car racing, and I've been following the series for quite some time now, and I'm a fan of Colin Turkington. Unfortunately, due to many commitments, I was unable to follow the series this year, but I'll try to see if I can catch up with what's left of this year's season.

[@carfan8838]

@@mohammednawfalal-damluji686 Oh, I might have misunderstood as you mentioned touring cars in the comment, my bad. As for the m6 which you mentioned above...I would say it was pretty successful, it doesn't have as much titles as the R8 or the amg, but then it also doesn't have much entries, it does really well in the 24hr races though. That being said, I too also hope that the m4 brings much more success than the m6. As for the comment you made on the dedicated sportscar platform, well from what I have observed BMW's gt3/GTE cars seem to be quite huge, the m4 is also quite a big car, so I would say bmw also needs to work a bit on it....

[@kunalmore5212]

Well in all honesty dedicated sports car chassis or not they do perform! Yesterday was the first free practice session of the 2022 DTM season and SVL set a blistering time at the Portemao circuit of 1:40. That just shows the M4 GT3 is here to win!

[@marijn17s]

Such a great car in my opinion, and the fact that my favourite team drives it makes it even better (ROWE Racing)

“Much smaller M4” Dude, the M4 is bigger than M6 and longer wheelbase than M8. It’s a monster. Love that it runs a turbo straight 6.

[@apexvisiontv]

Solid video. M4 is going to be successful just like it’s older family members 🔥🔥🔥

[@purplex360]

I hope that the front end of the future m4 takes some cues from the m4 gt3, where it actually looks decent

[@pheasant139]

Question: since inline 6 engines are generally longer than V8s placed longitudinally, would this switch from V8 to I6 shift the center of gravity to the front a little bit? If so, how would it affect the overall balance of the car? Is it possible to have a front-mid engine layout with an inline 6?

[@Xayuap]

it is possible, harder if transverse also, but possible alike

[@dylansmit3883]

It would. The I6 is inferior to a V8 when it comes to packaging, weight distribution and center of gravity. It's why BMW switched to a V8 with the E46 GTR in the first place. And it's why they bailed out of the DTM Class 1 era before it began (they weren't allowed to cut the firewall and move the engine back to better fight the V6 Audi, Opel, Alfa and Mercedes). The return to an I6 is a pretty weird move on their part after two decades of V8s. But I guess BMW feels they can compensate somehow.

[@pheasant139]

@@dylansmit3883 I know right! I was also wondering why. It is weird indeed...I'm not an engineer (just a high school student here), but I think if they were to package it like a front-mid layout, it would push the cabin even further back and create an extremely long front...

[@dylansmit3883]

@@pheasant139 They wouldn't be allowed to modify the engine bay to that degree anyway I think. The firewall needs to stay intact just like it did in DTM back in 1992. So that engine isn't really going anywhere.

[@BSport320]

Yes, the I6 is slightly longer and would shift the weight distribution forward but it's also 40kg lighter than the previous V8, so that could actually improve weight distribution. They can balance the car with the rear components (rear oil system, AC system etc.) if needed.

[@DJDiarrhea]

My god that grill is a travesty. BMW isn't making it easy to root for them. Seems like the car is well thought out though, exept maybe for the exhaust packaging. Can't wait to see it race

[@hersencell6880]

They just need to homologate the e46 m3 gtr for the fun of it.

[@davegelink]

My favourite is still the Z4 GT3 but the M4 is at least better than the M6 ;)

[@danielquimby9170]

If you watch the NEW ICON BMW video it seems to have a rear mount radiator. The larger opening on the rear quarter panel might be for brake cooling and the radiator.

[@BSport320]

That radiator is the rear oil cooler for the transaxle gearbox. You are right, the side intakes could be for that too but as far as I saw it their ducting only goes to the rear brakes. That video gives great insights!

[@spacecalander]

Amazing car, would love one for the street. First buy in Iracing.

[@AKK5I]

Hi not sure if you still read these comments, but you say the Z4 GT3 suffered from low top speeds as a result of rear wing drag and a smaller defuser. However the Bop adjustments made this car actually quite formidable because of its top speed, being able to overtake the 911 GT3 of the same year but not quite to the same level of a R8 LMS. Why might this be do you think?

[@BSport320]

BoP adjustments are never perfect, so you can change the car's characteristics quite a lot. If a car originally has very good top speed, over regulated BoP can make it the slowest of the field.

[@AKK5I]

[@BPF80MCar-vi1pg]

I would figure they would use a air to oil or water charge cooler like I've got in my F80

[@sebo8872]

It appears to me like it could have been easier to modify the M8 GTE for this purpose. I think they did just that with the M6.

[@dylansmit3883]

The aero rules between GTE and GT3 are so different it made Porsche switch the 911 to a mid-engine layout. I doubt converting the M8 would have been that easy.

[@mohammednawfalal-damluji686]

Although I think that GTE and GT3 have many similarities, it seems that it's not that easy or cost effective to modify a GT3 into a GTE or vise versa without the car being built up from the ground up to accommodate both regulations. Also, for reasons that I still don't know, a GTE car is significantly more expensive than a GT3 car. Until the new Aston Martin Vantage GT3/E was introduced in 2018, the Ferrari 488 GT3/E was the only platform that was built to comply with both regulations, as both Aston Martin and Porsche used (Porsche still does) different platforms. I assume you heard about the proposal of updating GT3 platform to the GT Plus concept for the new DTM championship, with some upgrades such as higher power and removing some driving aids such as ABS, but the concept didn't go through. I remember reading an article about that topic, where an individual from the Lamborghini backed team Grasser Racing mentioned that it wasn't that easy to update GT3 cars to the GT Plus concept, as that required changing many parts and testing them, which would drive up the cost in an unfavorable way. As for the M6, it was converted from a GT3 into a GTLM, and it had some waivers, if I'm not mistaken, and the car, while it won some races, wasn't as strong as the rest of the field that it competed against (Corvette C7-R, Ford GT LM, Porsche 911 RSR, and the Ferrari 488 GTE).

[@corsamode]

@@mohammednawfalal-damluji686 Slightly off topic here, but since you're talking about GTLM & GT3, I'm really curious to see if the GT3 cars can keep up with the detuned C8.R next year.

[@mohammednawfalal-damluji686]

@@dylansmit3883 I tried to search on how different the aero rules between GTE and GT3, but I couldn't find that much. There are differences, but I wouldn't call it so different, because after all, both classes are based on production cars, and there are more similarities than there are differences with the current iteration of both classes. As for Porsche, the reason they decided to go mid-engine with the 911 RSR was to fit the larger rear diffusor, since the regulations of LM GTE in 2017 allowed for larger aero bits. Also, the regulations of LM GTE allowed a car manufacturer to change the engine's position, considering that particular car meets a certain production limit.

[@mohammednawfalal-damluji686]

@@corsamode If I'm not mistaken, Chevrolet announced that they won't do a GTD version of the C8, but at the same time, I don't see them leaving IMSA WSC, especially with the current domination the Corvettes are having in the last couple of years, and currently. So, it's possible that they will reconsider (if they didn't already, I don't know about that) introducing a revised C8-R that will comply with GT3 regulations. I'm also looking forward to see how IMSA will integrate GT3 as a replacement for GTLM. Since GTD is a slightly detuned GT3, it looks like GTD will be split into a PRO and AM classes, with PRO being the replacement of GTLM, while the current GTD will be open for AM or PRO-AM, or something similar.

[@damncritics]

Are those air intakes on the sides of the headlights? If so, what do they do?

[@BSport320]

LED headlights need cooling but I think these side extensions of the lights are no intakes. It looks like they just continue the design into the wide body.

I think the good old BMW was lost along the way. Now it's so influenced by their OEM completion or their lust for Profits that the management lost its passion for performance cars. It seems that accountants run the company now instead of passionate petrolheads. And it seems that the latter don't have the slightest influence on the direction of the company. Now they try to sell cars by deceiving their audience trying to do all things at once instead of innovating and building on their heritage. The car is big, heavy, inneficient cooling and aero. At least the grills looks better than the roadcar. I think it's really funny that the grills on the road at look larger than the fricking racecar. Sadly it's just a marketing scheme so that they can sell more cars. I pitty those engineers having do deal with Management everytime they try to do something right...
