BMW M5 Concept

The M5 concept to debut at the Shanghai motor show later this month will have a twin-turbocharged 4.4-liter V8 engine, from other M models following the shift in most of its models from twin-scroll turbos to two separate turbos.It will be the first time the M5 has not had a naturally aspirated engine since its launch in 1984. However, the fifth generation of the iconic four-door powerhouse will have substantially more power and torque. The previous model was a five-litre V10 with 373kW of power and 520Nm of torque, while the coming model has 417kW and 691Nm.That more than matches its main sedan rival the Mecrcedes-Benz E63 AMG 8-cylinder engine with 386kW and 630Nm. While no official acceleration figures have been released, it is believed it will be 0.2 seconds faster to 100km/h than the V10 M5, which at about 4.5 seconds would equal the Mercedes-Benz E63 AMG.
Despite all this raw power, BMW claims fuel economy increase of 25 per cent thanks to "EfficientDynamics" features such as brake-energy recuperation, an alternator that disengages under acceleration and an automatic stop/start function.
The new engine is also set to appear in the second-generation M6 coupe and convertible, and possibly a four-door GranCoupe to rival the new Mercedes CLS63 AMG. BMW Group Australia spokesman Piers Scott says the M5 will arrive here early next year.the V8 twin-turbo is part of a "general shift towards turbocharged engines in the BMW line-up".BMW TwinPower Turbo technology means superb power delivery from fewer cylinders,This particular V8 is a characteristically high-revving engine typical of BMW M and like the V10, has a sound that is more than capable of making the hairs on your neck stand on end."Another significant change to the new M5 is the introduction of a dual-clutch gearbox replacing the old model's sequential manual transmission. Scott says the transmission will be well received.expect both performance and flexibility from a transmission,
This double-clutch transmission ensures fast, seamless gear-changes to compliment the enormous power of the engine yet can offer a smooth and subtle driving experience for the daily commute."
