VIDEO: Mazda P2 diesel in-car

Mazda and The RACER Channel take you for a first look inside the manufacturer's new SkyActiv diesel P2 racecar while testing at Palm Beach International Raceway with SpeedSource Engineering owner/driver Sylvain Tremblay at the controls of the four-cylinder bi-turbo prototype. Chassis vibration has its fun with the audio at times, but the unaffected engine sounds can be heard as well.
