The new V8 Power Unit for the BMW M3.
Description in Brief.
? 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 (445 lbs. total weight).
? 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.

Sounds very exciting. Too bad we will not yet see a 10000rpm M3. I think they could have done that. Just for the fun of seeing the big 10 number on the rev cluster, even if the engine revs only to around 8300rpm.

My Ride: '05 545i - scheduled for ED pickup in Munich on 7/22!

My favorite part is the 2 oil pumps good for 1.4 g of lateral acceleration!

damn ... so little torque
So interesting is the power/torque chart, it's the ideal output ratio for me.
The linear climb of the typical NA engine but also with an almost flat torque line from 3500-7000rpm giving full torque delivery (400 NM) and even at 8500rpm the engine delivers mindblowing torque (almost the same peak value of the last M3) but near the redline here.

The same as in the Porsche GT3. But that weighs way less but in a way the M3 will balance this with proper gear ratios in the 7 speed gearbox. Just as in the M5, the ratios will act as a "torque multiplier".

i suppose im just spoiled by 700nm (soon to be 850nm)
