by Brian Byrne The new BMW M5 has 507bhp of power, 520Nm of torque, and a 0-100 km/h time of 4.7 seconds
It is powered by a 5-litre V10 engine and features a seven-speed sequential gearbox.
The new engine delivers two levels of power output. Each time it is started it is in 400bhp mode. This is to suit normal urban traffic conditions where 507bhp is of no use and not required. By operating the MDrive button on the steering wheel the power is increased to 507bhp.
