2012 BMW M5 Safety Car With Akrapovic Exhaust [Video]

BMW used this past weekend’s Indianapolis MotoGP to unveil its new F10 M5 safety car. The BMW was fitted with an Akrapovic titanium exhaust system that sounds amazing. Other goodies that set this  safety vehicle aside from all other standard M5’s include high performance coilovers, new front and rear spoilers, Recaro bucket seats and 20-inch rims.

The M5 has been entirely redesigned but the biggest change is the switch from a high-revving V10 to a 4.4-liter twin-turbocharged V8. The new engine will crank out 552 horsepower and 502 lb-ft of torque mated to either a six-speed manual or a seven-speed dual clutch transmission. The car is capable of achieving a 0-60 time of 4.4 seconds, not bad for a car weighs around 4,000 lbs. Pricing has not been announced but the M5 will probably sell for around $85,000.
