I guess we'll just have to wait and see what the real thing looks like.

I'm pretty confident BMW will not let us down here. That said, I am still amazed that they let that cheap looking boomerang vent make it to the production 4 series, so who knows these days.

Prolly noob question here: what does an 8k rpm redline at 400hp/400lb.ft mean in terms of exhaust note?

Cautiously optimistic myself, but yes, the 4-series coupe shots worry me as well.

Still a six cylinder so my guess is that means it'll sound like one? I will miss the sound of the current V8 as well.

Why do car reviewers still post dyno graphs? They should be plotting the car's data log of longitudinal G and test conditions (elevation, ambient temperature etc). At least two gears and top gear if possible. That would give a very accurate picture of how the car behaves in real life.

Coming back on topic, I would be most interested to know the static compression ratio of the new engine, as that has a strong bearing on how much boost it can take before necessitating a change of parts. My wild ass guess is probably around 10.

Sucks that all the other competitive models such as the C63 and RS5 are keeping theirs... Ppl here like the downgrade to 6-cyl but absolutely NO ONE would have said no to a F82 M3/M4 V8!

It's true, but it's hard to find fault if they can pull more power and better fuel economy from the car without significant turbo lag.

But couldn't a more efficient V8 have been produced as well while remaining NA?

My guess here is economics. They're looking for more broadly applicable platforms. There is a ton of easy flexibility in FI just via ECU and plumbing games.

This is silly and I know, it but it still bothers me that the coupe is stuck with the (meaningless as far as I'm concerned) "M4" badge.

M3 and M5 are legendary. M4 to me carries no weight. Again purely psychological, but I can't get past it... Lol

The numbers and overall design do look solid though. If the price isn't ludicrous ill take a hard look (and just be pissed everytime I have to explain that no, it isn't an M3)

[FogCityM3]

Looks more promising. However, still have some concerns about the chassis feel and overall size. As will be based on series car (which many have argued and I would agree) doesn't feel as good dynamically as the E9x or E46, and given the cost-conscious focus of BMW (engine sharing), the issues they've had competitively with the M5, M6, and 3 series (losing comparos), it will take a lot to fill the E9x shoes. Not sure 440 turborcharged horses for a 150 lbs lighter car, with a weight to power ratio of around 8.0 lbs/hp with electric steering is going to be much of a "leap" performance wise or driving-dynamic wise. Probably a low 7:50s on Nurburgring (ever wonder why on industry days in April/May 2013 footage of the E90 M3 CRT still being driven around keeps popping up).

[MCHL]

traditional handbrake or electronic one?

[Nazarin]

I belive this car will be very intresting, special to see how ballance will be with those info we have so far: close to 8k RPM on engine 6l, 395 tourge, 415hp, less wight, all that to be so balance that we espect to be better then S65....
we will see..:d

I belive it will be, i can;t wait to see that car how will manage on the track

The only reason to do it is if the car is faster by letting the engine rev to ~8k. This would mean one of two things:

- The engine is still capable of making more power at that RPM.

- The engine's power peak comes before 8k RPM, but the decrease in power above that point is offset by targeting a higher RPM for the next gear change.

One thing we can be sure of is that BMW will not produce an engine that revs to nearly 8K RPM at the expense of performance.

A V8... really..?

Are you unaware that the current gen M3 is powered by a naturally aspirated V8?

[car7]

Many would say no to a normaly aspirated v8. My e92 m3 was just to slow. Bmw is about I6.

[bimmerjph]

This is good news!

Wouldn't that make this the highest revving turbo production car (or at least currently produced)? I don't think the new 911 turbo even goes this high.

Edit: 911 Turbo S tops out at 7.2k rpm.

Edit2: The McLaren MP4-12C goes to 8.5k, so nevermind that.

RS5 will be moving to turbo V6 with the B9...

Not seeing the correlation between those two sentences.

Your tag says you drive an M3, I hope you are aware that you're currently driving one of the most successful V8's in the German auto industry..

Beware people...
It's not a 8K redline, but a near-8K RPM redline! In marketing terminology, 7700 RPM is also near-8K redline...

Even if it would have 'only' 7700 RPM, that would still be an achievement, compared to the 7000 RPM redline of the current 3L turbo petrol BMW engine (N55), which the new M3 engine will be based upon.

+1. Everyone keeps talking 8k redline but the fact they said 'nearly' means its not 8k.
