New 4.0L V8 for the upcoming M3 - official
It's official. Go to worldcarfans.com for the full press release. Here is the summary:
-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.

Here are the HP and torque curves. Pretty flat torque curve above 3500 rpm, but the peak torque is not that impressive. Like the M5, the new M3 will depend on high engine speeds to accelerate.

i'll see how i feel about the new E92 M3 when the dealer calls me and then i'll decide.

what bothers me is that it's under 300lbs-ft of torque, the stock 335 has more peak torque! 420hp isn't bad, lightweight, 85% of its torque available after 2000rpm, 8300rpm redline, isn't bad at all.
but 295lb-ft of torque!?!?!?! WTF?!?! the powerband is decent, but still I agree with jtc55, it should have had at least 330lb-ft.
I may have to reconsider this one...

Low TQ, High Rev, and that tumor on the hood? Hmm...... I have some major reservations for this car. In the Northeast, where there's snow, I'll probably take a E92 335xi over this.

From a specific output standpoint the car is a mechanical wonder. 105hp/liter is a very lofty goal indeed in an NA car. However the torque number is disappointing to say the least. Once again this is a car that isn't going to win a lot of stoplight battles.

unless you drive it like you "stole it", it would be hard to keep the rpms boiling at every stop light. From a roll, you will need to use lower gears to keep the power band on, say bye bye to MPG.
any word on the SMG3 on the M3?
with 1 extra gear.. it would make the 295lb/t not so bad (like the M5)
