I think you must have mean S65 there, yeah? I am pretty sure that the S63 is a lot heavier than an S54 (and by extension, S65) due to all the turbo infrastructure.

Still, that hardly leaves "a little suspension" as the only difference between an M3 and a 3 series. The improvements made to the car to go from 3 to M3 are numerous and significant. I'd suggest a little research - it will be enlightening. |

I do kind of care because I love seeing ///Motorsport tech in street cars, but in the end, I have to admit that you're right. I would be fine even if the next M3 is a hybrid with a CVT as long at it is fast, light and handles. You have to ask youself what is most important -- performance or something else. |

no turbo mambo jumbo
M3 should always be N/A. throttle response of FI cars will always be inferior. i say go back to I6, 9k rpm and 380hp in lighter, say 3100lb chassis. all else is garbage. |

BUT ... Why are you so sure that the M3 is not getting an V6 and an N54/55 based I6 instead? Have you better inside informations? Why do you think that the M-GmbH is not able to change their mind ... its 100% clear that in the begining the N54/55 based I6 was the absolut favored engine choise ... but at that time cost reduction is the overall/only thinking that was possible ... but if you take a look at cars like the upcoming M3 EVO and M3 CSL, it looks like the M Spirit is back again ... and an unique engine design was one off the M roots ... and an V6 derivate of the S63 and an S65 BiTurbo are the only engines that could fullfil this sprit.

Get ready for tri-turbo V6.
These news, and yesterday's track day makes me feel so good about my M3.

Jesus. If they bi-turbo the S65, as it's already a very efficient engine... ![]() I'm not getting my hopes up, though.

That's no surprise though, because S54 is very heavy. And this is kind of a tricky marketing on BMW side. Without mentioning that S54 was very heavy for it's size, they make it sound like they made a very light V8.

M3 I6
I'd have to go with a twin turbo version of the next gen turbo I6. Put this in a lighter chassis, which they will since the CFRP will be more readily available for body panel switches going from F3x to the M3. I can't even imagine a V6- absolute BMW sacrilege.
Luxury goodies won't be going anywhere since so many want them. Ad long as the brunt of them are optional, what's the issue? Weight has creeped upwards for safety and features and size. I believe we are witnessing the plateau and next the reduction as lightweight technologies improve and costs associated with them decrease. Also, for an M-specific engine, they could bore it out a bit for more displacement. We know the mass produced engines will be in 0.5L cylinders, but M could and should be able to modify that for their purposes. Let's just hope the feeling full hydraulic steering rack makes it into the next M3....

For me, it does not stand to reason that BMW will develop a brand new engine configuration for an M3/X3M/M4/X4M/Z4M when they did not go that route for the M5/X5M/M6/X6M. I acknowledge that sometimes things don't fall into place nicely and you have to invest more money to get results. The S65 and S85 were born from that type of need. But in the end, they've made the N63 work as the basis for an engine to power the latest generation of large M vehicles, and I have not heard a single compelling piece of information that leads me to believe that they cannot make the N54/N55 work as the basis for an engine to power the upcoming medium-sized M vehicles.

The S63 or S65-turbo solutions have this same disadvantage. Either one will mean gaining engine weight vs. the current setup. An N54 or N55, on the other hand, weighs less than an S65. |

Rumor: BMW Testing Four Engine Configurations for Next F30/F32 M3
How is everyone? The F3X M3 is going to be a V6 turbo motor! Not only because BMW have themselves announced this but by comparing how the S65 was previously engineered to be very much alike the V10 which has now been discontinued…. V8/V10 engines that have high revving natural aspiration.
The new F10 M5 engine has a reverse port flow bi-turbo engine. It has taken time to engineer this because a twin-power turbo X5M/X6M engine cannot be attached by motor mounts to a coupe without cutting a hole in the hood. The F10 M5's engine not only has less width and length: dropping 2 cylinders and direct injection. The height has also decreased dramatically compared to two snails sticking out of the top via revised bi-turbo engine. ![]() Inside the new engine compartment expect to see a lot more plumbing, two functional front bumper intakes to feed more air into the Bi-turbo V6. I wouldn’t count on having a hood air inlet towards the windscreen. Speculation about hood intakes only being advantageous above 110km/h. Expect the same power…. 375 rwhp available with a true M-power button with 100hp on tap. ![]() |
