Latest BMW M4 Coupe F82 Spy Pics and Updated Info (Nearly 8000 RPM)

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.

The latest M3/ M4 details (updated) we have are:

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 (source, source)
Nearly 8k RPM redline (told to us by someone intimately involved in BMW M3/M4 development)
DCT and manual transmission options
Optional M Carbon Ceramic Brakes
Rumored Electric Power Steering (completely reworked for precision for M3/M4)
Prototype Tires (from prototype) - Michelin Pilot Super Sport: 255/35/19 (front), 275/35/19 (rear)
Front styling to feature elements from the M6 and 1M coupe, with Air Curtain technology

Kidney grilles feature double-slats with M3/M4 badge

M3 Introduced late 2013 - early 2014 (concept debuts earlier)
M3 European Delivery begins June 2014, at earliest
