For the first time an M5 features a turbocharged power unit – a high-revving 4.4-litre (4395cc) V8. Developing 560hp from 5750-7000rpm, it is the most potent series-production engine ever to emerge from BMW’s high-performance M division. Incorporating the company’s M TwinPower Turbo technology, twin-scroll turbochargers, high-precision direct fuel injection, VALVETRONIC variable valve control and a cross-bank exhaust manifold, it guarantees the legendary BMW M-car thrust with seamless lag-free delivery from little more than tickover speed – thanks to 680Nm of torque from only 1500rpm.
Compared with the previous V10-engined M5, maximum power is up by around 10 per cent and peak torque by more than 30 per cent. As a result, the latest M5 can accelerate from 0-62mph in just 4.4 seconds, and 0-124mph in only 13 seconds. The voluntarily limited top speed is 155mph. With BMW’s seven-speed M Double Clutch Transmission Drivelogic and Efficient Dynamics technology, including engine Auto Start-Stop and Brake Energy Regeneration, the M5’s fuel consumption has been reduced by more than 30 per cent to 28.5mpg, while CO2 emissions tumble to 232g/km.
The new M5 Saloon will be available in the UK in November 2011, priced at £73,040 on-the-road.
