Lets hope. The S63 is nice, but not legendary. Will be tough for the F8X engine to be legendary. It will have to be better than Toyota's 2JZ.

It's legendary in the sense that it is, until now, the best V8 turbo engine ever made.
And I have no clue what you mean with 2JZ, but you just stop it right there!

Actually, the 2JZ is maybe the best engine Toyota has ever made:

But that's just a small history lesson, so let's stick to the M3, shall we?

2014 BMW M3 / M4 to Gain About 100lb-ft More Torque While Targeting E46 M3 Weight

Zafiro · Oct 5, 2012

Same power as current M3? really?

I would happily prefer the same HP or even less and 300lbs lighter.

I prefer more power and lighter body. Why chose?
The competition is very tight today so BMW need to make something to stand out for years like the current M3.

Sunny · Oct 5, 2012

^Well, the current M3 has the least power among it's competitors and yet that didn't stop it from being the best of the class. It takes more than just a headline grabbing max HP number to really "stand out".

Weight is king when you are wanting to build an exceptional handling car, but this doesn't necessarily make it a better car overall because of this fact. It all depends on what you as the individual are wanting your car for and it's up to the manufacturer to balance these things to hopefully suit everyone.

Differnce is though, that the competition is much stiffer today. Next A4 and C-class is going to be better than ever. Look at the new Cadillac, it matches the new 3-series in many areas and this is an american car (no offense). BMW can work on both power and weight and improve it, why focus only at one thing.

The key consideration when it comes to rationalising the M3's power is how high the engine will rev. Sure, it'll make dollops of torque but if max power is produced at 6000-6500 RPM - that's just about 2000 rpm shy of the S65's max power RPM.

Engine Type Torque (Nm) RPM Power (kW)
S65 @ Max Nm.....400 3950 165.46
S65 @ Max RPM..352 8400 309.64
S55 @ X RPM......535 5500 308.14
S55 @ X RPM......498 6000 312.90
S55 @ X RPM......463 6500 315.15
S55 @ X RPM......440 7000 322.54

Basing the assertion as per F30Post that the "S55" makes 100 lb-ft of torque more than the S65 this would give a peak torque output of 535 Nm.
Assuming that the S55 shows a similar drop off in torque as the S63Tu = approx 7% after, say, 5500 rpm (we can safely assume the S55 will sustain this torque peak to this RPM) then the max power can be calculated.
If the 7% drop-off is a best case scenario then if the S55 revs to 6500 rpm the power output can be expected to be 315 kW based on the reported increase in torque.

Yes, no one is denying competition is tough, but I am just pointing out the irony of you using E9x M3 to make a case for the need for more power - when in reality, it is a perfectly good example of why you don't need to be the most powerful car in the class to be the best in class.

Yes M3 E92 did well so did M3 E46 but the times are tougher now. Personally I think the new M3 is getting more than 420hp.

Next M3 may be lighter than expected, with lots more torque

Horsepower in the F80 M3 and F82 M4 is said to be close to that of the E90/E92, which was rated at 414 hp. This contrasts with previous reports that had horsepower pegged closer to 450. It should also be noted that BMW has been known to underrate the horsepower values for its engines. That said, the new turbocharged straight-six will supposedly develop 100 more pound-feet of torque over the current generation, too. The 4.0-liter S65 V8 found in the E90/E92 M3 developed 295 lb-ft, putting the new engine's torque in the 395 lb-ft neighborhood. We can live with that.

An equally interesting development regards the proposed weight of the new Ultimate Driving Machine. Apparently BMW is targeting the curb weight of the E46 M3. That older-generation Bimmer clocked in at about 3,400 pounds, while the E90/E92 M3 had grown to over 3,700 pounds. The 300-pound weight savings should come as welcome news to M3 purists, critical of the progressive weight gains from generation to generation.

For those interested in the aesthetic of the next performance-Bimmer, the F80/F82 update of the M3 is claimed to feature a more aggressive look, highlighted by a power bulge hood and larger fenders. That styling direction should not come as much of a surprise, as the more aggressive appearance is customary to the M3 by now and matches what we've seen in spy shots.

According to source, the F80 M3 sedan will debut first and come to market in early 2014. It will be followed by the M4 coupe, though exact timing was not revealed.
