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.
With this newest details, we've updated our M3/M4 features list:
• Lighter than current M3 (targeting E46 M3 weight (
source))
• More powerful than current M3 (approximately same HP (
confirmation?), but around 100 lb-ft more torque (in range of 395 lb-ft) (
source)
• Faster than current M3
• More efficient than current M3
• Powered by "S55" inline 6 cylinder multi turbo engine (
