Nearly a month ago, we spotted the first non-black F82 M4 coupe prototype (in Silverstone) on the road (reposted below).
We've just spied a Silverstone F82 M4 testing on the Nurburgring, wearing M Carbon Ceramic Brakes. This prototype doesn't reveal any new physical details, but we do have a new technical detail to share.
We were recently told by a high-ranking BMW M official intimately familiar with M3/M4 development that the engine powering the M3/M4 will feature a nearly 8000 RPM redline. As we've reported all along, the M3/M4's S55 engine will be an inline 6 cylinder with mutiple turbos, outputting around 100 lb-ft more torque and approximately same horsepowers as the current M3 (S65) engine. For comparison, the current M3 engine redlines at 8400 RPM.
