Video: BMW teases the sonic capabilities of the much-anticipated M3/M4 successor’s engine

BMW’s YouTube channel has just posted a teaser for the sound produced by the 3.0L twin-turbocharged inline-six expected to see duty in the incoming BMW M3 and M4 coupe.

Rumored to produce around 450hp and 405 lb-ft of torque, both cars are said to sprint to 62 mph in just 4.2 seconds for a top speed limited to 155 mph.

The BMW M3 and M4 coupe are expected to debut later this week in concept form at this year’s Pebble Beach Concours d’Elegance, with production models following at the next Detroit Auto Show.

Check out the teaser after the jump.
