About the 5 Series 5.0 M5 (507 Hp) RWD

507 hp from a 5.0-liter V10 that revved to 8,250 rpm. BMW put a Formula 1-inspired engine in a luxury sedan and dared you to use it. The S85 screamed at high RPM with an intensity that no sedan engine has matched before or since. The seven-speed SMG was divisive — brilliant when it worked, frustrating when it didn't. Rod bearing anxiety became a rite of ownership. But none of that matters at 7,000 rpm in third gear, when the V10 is doing something that makes you forget everything else about this car, good and bad.
