Hot Laps with Bill Auberlen at Sonoma Raceway | 4K 

Part of the full day at M Track Days includes some time with a professional driver (BMW M Motorsport) and at Sonoma, we got treated to Bill Auberlen--no stranger to our channel. He picked up participants at the skid pad for 1.75 laps around the NASCAR configuration in the M3 Comp xDrive and was an absolute beast in this car.
