Throughout its existence, BMW has made some pretty epic engines (and some not so epic), but their most powerful engine wasn’t actually put in a BMW car. It was the McLaren F1 that received BMW’s S70/2 6.1-liter V-12 back in the day, and for a long time, that was the brand’s most powerful engine. Until now, that is. Things have changed and we have the BMW M5 CS to thank for that.
The hardcore version of the super sedan comes with the familiar 4.4-liter, twin-turbo, V-8, but power output is now 627 horsepower – 10 more than before. Torque remains the same at 553 pound-feet (750 Nm). The bump in power may be small, but the M5 CS boasts a faster, 2.9-second time to 60 mph (97 km/h). The 0 to 124 mph (200 km/h) happens in 10.4 seconds and the top speed is electronically limited to 190 mph (305 km/h).
The BMW M5 CS will be lighter than the “normal” M5. US-spec cars boast a weight loss of 230 pounds (104 kg), while European cars are 70 pounds (32 kg) lighter.
