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.
