Back in September we brought you video of the latest BMW M5 test mule undergoing testing at the Nürburgring. Aside from the fact it’s always good to see a new M5 on the way the sound from the car in last month’s video was, well, quite disappointing, really. Never mind, though, as this new clip from Car magazine shows that BMW has started to put things right. The twin turbo 4.4 litre V8 is sounding much nicer now!
Reportedly, the M5’s V8 will be good for 578hp, a slight 22hp increase on the 555hp found in the X5 M’s 4.4 litre heart of gold.
It’s understood we’ll see an M5 concept at Geneva next March, with the production ready model on show at Frankfurt in September 2011.
