Official - The New V8 Power Unit For The Bmw M3

[FrenchBoy]

From BMW marketing site:

•First eight-cylinder for the BMW M3 sports car.
•Supreme performance ensured by 309 kW/420 hp from 4.0 litres.
•Maximum torque of 400 Newton-metres (295 lb-ft) at 3, 900 rpm,
85 per cent of maximum torque over a speed range of 6,500 rpm.
•Unique thrust and muscle ensured by consistent implementation of the M high-speed engine concept, maximum engine speed 8,300 rpm.
•Consistent lightweight construction of engine and ancillary units,
new V8 power unit one of the lightest eight-cylinders in the world,
lighter than the straight-six power unit in the former model.
•Variable camshaft control, low-pressure double-VANOS for an
optimum charge cycle, system offering full power and performance even with normal engine oil pressure.
•Eight individual throttle butterflies for spontaneous engine response.
•Consistent and reliable oil supply with longitudinal and lateral acceleration up to 1.4 g ensured by two oil pumps and wet sump oil lubrication optimised for supreme dynamic behaviour.
•Exhaust system optimising cylinder charge, optimised for weight and function by means of internal high-pressure remoulding, exhaust emissions fulfil EU4 and LEV 2 standards.
•Upgraded MSS60 engine control unit for optimum coordination of all engine functions with the various control systems in the car.
•Ion flow technology recognising and distinguishing engine knocking phenomena as well as misfiring and miscombustion by measurement of ion flow in the combustion chambers.
•Brake Energy Regeneration with intelligent alternator control.

Wow, the new V8 is 33lbs lighter than the previous 3.2 M3 engine.

[Markus03]

Disappointing specs - thought the torque would be much better than the 335 and more available at lower rpms! Yeah, i know it's supposed to be a high-revving engine, but off the line from a standstill, the guy with more torque is gonna get the inital surge.

I know the M3 will make up in the handling and ride department, but for now, I'm a little disppointed...

I agree, the fact that stock m3 and 335 torque numbers are very similiar and a proceeded 335 can gain as much as 70+ torque for under $1300 makes this such a disappointment... Tuning this thing is gonna cost a fortune and will performance really be enhanced much more....I think the 335 will definately hurt the m3's market...

Admittedly, the torque is a little low, but I'd rather have the 8300 rpm ceiling and give up 10-15 lbs. of thrust. All of us knew that the torque numbers would in the low 300s. The 335 may achieve it's torque a little lower, but in the real world the M won't be giving anything up. The 335 only has 5 more ft. lbs. and personally I don't care that it does it @ less than 2k.

[jjraiser]

I agree with all of you that the torque should better than the 335, but don't forget about gearing. I assume BMW will see the disparity too and gear the M3 in a way to capitalize on the high-revving 8. Besides, it's all about going faster easier and that is through well planned gears, not forced induction if you can help it. I can't believe how light it is!!!!!! Great for handling. I wonder if The M3 will have a slightly rear-biased weight distro????

Thanks for the BMW pdf file on the engine. The ink is still drying on my copy now!

[ynotony]

Big deal, so the torque isn't max until 4000rpm. If you are driving aggressively would you ever let the revs drop below 4000rpm? If you do you're doing something terribly wrong. especially with another 4300 to go.

A little more torque would have been nice though. Heres hoping to an official weight announcement. the engine is already like 10kg lighter than the 335i.

[-JLT-]

i too am quite disappointed w/ the low torque numbers. i know the E92 M3 will still be quick but i think i'll miss the thrust of high torque

[swamp2]

Guys, relax, dont fret about the torque, like ynotony said you should not be driving a car like this (when driving aggressive) below 2k rpm. This sucker is going to be fast! Look at the M5 - low torque, high hp, high redline - keeps up with exotics costing twice as much!! M3 will be the same story. Look at F1, sure the new M3 is not F1 weight, but with the RIGHT gearing the concept for speed is: high hp, high redline, broad torque curve, modest torque. 335i is going to be schooled so hard...

The 335 will never can rev to 8400 rpm.

The key to acceleration is short gearing combined with high rpm. This new M3 will have rear axle ratio of at least 3.62 or 3.73, or maybe even 3.91. It is about torque multiplication.

And then the wide torque band, at least 85% of max torque available over a range of 6500 rpm!!!!!!!!

I hope so man...I really do

[M3onTwomps]

Guess the low torque upsets the drag-racing, fast and the furious crowd.

Also, you don't want the 335i to rev any higher.....the torque curve for the N54 drops off aggressively with the RPMs.

No, it upsets the lazy grocery getters that want to drive aroud town in one gear and never have to shift.

I might be the only one that thinks this, but I think that this constant comparison between the 335i and the E92 M3 is really a little bit childish. Both cars are great in their own regard. With the New M3, you will get a NA factory tuned high revving monster with a harsher ride and a throaty exhaust roar that will completely dstroy the 335 non tuned

With the 335i, you get a civilized engine for people that want a -great- commuter car with the extra adrenaline rush for those long drives.

I understand the need for the M3 to beat the 335i by a significant amount, but what one needs to realize is that out the door, it already does. With the same torque figures and approximately 100 more HP and a construction that should only be marginally more heavy than the 335i, there is no doubt in my mind that the true car enthusiasts car will be the M3.

Also, comparisons between the Porsche and the RS4 and the Z06 are just as pointless. Why is there a need to prove who has bigger engines? It ultimately comes down to if -you- enjoyed your purchase, comparing only diminishes the joy- sure there will always be faster cars out there, but not cars with the whole package, not cars with the driving feel of a BMW. because in all respects I do believe the M3 will be a -great- drive.

the M3 has never dissapointed before, it won't now.

Bad statement. People that drag are part of the "fast and furious" crowd? Might want to re-think that.

yep and your point?
is there something wrong with wnating a car that has fast 1/4 mile time?
i guess u want a car that run at 14sec and only do well on the track

not me...lol

Word!

Are you guys crazy!? You're freaking out about 5 lb/ft of torque! Whoptie! The technical acheivements on this engine are amazing! I can't wait to drive one!

[carnuts3]

All this talk is pointless. The bottom line is that I guesstimate that this car will conservatively do 0-60 in the mid-4's, and the quarter mile in the mid-12's. What's wrong with these numbers??
