BMW is teasing us with the sound of its motor for the upcoming M3 and M4, most likely, in this video simply titled, “BMW M is preparing something new.”
The 3.0-liter biturbo I-6 is expected to make up to 450 horsepower. We could see the motor in concept cars very soon, with Pebble Beach Concours d’Elegance and the Frankfurt Motor Show on the horizon.
Listen to the soundtrack in the short video, below.
