S55 3.0L inline 6 engine

A member of F30POST has recently discovered a BMW VIN which brings important details about the next-generation M3 and M4 Coupe.

Both cars are expected to get an S55 3.0-liter inline-six engine developing 415 hp (310 kW), which would be just about the same as the current M3 with its 3.0-liter inline-six multi-turbo S55 pumping out 414 hp (309 kW). However, torque figure will be increased by about 100 lb-ft (135 Nm), reaching somewhere around 395 lb-ft (535 Nm).

The new M3 is expected to go on a diet to lower its curb weight to 3,415 lbs (1,549 kg), making it considerably lighter than the M3 E90 (3,726 lbs) and the M3 E92 (3,704 lbs).

The next-generation BMW M3 will be launched late this year or in early 2014, before going on sale in June 2014, while the M4 Coupe won't be out until late 2014.

"the current M3 with its 3.0-liter inline-six multi-turbo S55 " WRONG. The current M3 has a naturally aspirated V8.

"which would be just about the same as the current M3 with its 3.0-liter inline-six..." So the current M3 has six cilinders?

I prefer the current V8 model with the ESS supercharger with 625 HP... and no fake sounds in the cabin, it's a original soundtrack :)

I dont see fake sounds as a big deal, if you dont like it you just unplugg the wire, but during those winter days when all windows are up you might want a little louder music from the engine, dont you think?

so when them two comes out then M3 is equal RS4 and M4 is equal RS5 and still current M3 is compact size, Market Segment: Near-Luxury, Performance, where RS5 is sub-compact size and Market Segment: Luxury, Performance... so based on them photos the all new M4 going to be more Luxury so it will take more weight on board but at same time loses weight with having smaler but not weaker engine... so will see how it will work out then...

Ok....I'm confused.... In this article they still mention M3 and M4 cars.... I thought the M3 is changing name as the M4....now what the hell is really going on? Didn't BMW say their sports cars are getting equal numbers? Meaning the M3 will be known as the M4??? Can someone explain?

M3 is sedan based on the 3 series and the M4 is coupe based on the 4 series coupe. M3 name still lives, only not in coupe form, thats M4.

Is the horsepower war really over? I think not. The RS4/RS5 are more powerful, and the C63 even more so. I have a hard time believing that the new M3/M4 will only be 1hp more that before despite being lighter. Speaking of which, the engine 'S55' sounds like an 'M-developed' improved version based on the N55 (single turbo). I hope therefore it has atleast two turbos and a slightly higher displacement to make it unique. A 3.3L I6TT would be great. And at least 450hp.

Horsepower war is over, its not all about horsepower, its about making the car brilliant as a whole thing, and when it comes to driving thats were the M cars are the best, and I have no doubts that the new M3/M4 will yet again be the best car in class.

I agree with Ratt, it's over. Now it's more with driving dynamics and precision tuning. The current M3 does not have mega horsepower, but it still drives better than its competitors on the track. So with a lighter body, I'm sure the new M3 will be better.

@alamak @Ratt I see your point, the current M3 is better than it's competition . I just don't believe the horsepower war is over but I agree it should be. Lowering the weight will make for better performance than making a bloated car with lots of horsepowers under the bonnet.

Whilst I'm pretty sure this will be impressive, I'm afraid we won't be hearing the beautiful growl of a straight-6 n/a anytime in the future :(
