2015 BMW M3, M4 Leaked

BMW’s new M3 and M4 siblings just leaked ahead of their official debut.

As you probably already know, BMW is using a 3.0-liter turbocharged six-cylinder in place of the former 4.0-liter V8. The powerplant is said to make 420 hp and almost 369 lb-ft of torque between 2,000 and 5,000 rpm with a 7,500 rpm redline. A six-speed manual is still standard while a seven-speed dual-clutch is optional.

It also uses an Active M differential as an upgrade over the outgoing M3’s limited-slip unit. BMW is expected to officially debut the car tomorrow, so expect more details soon.
