HAVE DIESEL WILL RACE (AND LEARN)

Mazda's factory SkyActiv diesel race program switched to the Prototype class in 2014, teaching the SpeedSource team valuable engineering lessons for 2015.

FORMULA SAE STUDENT ENGINEERS, TAKE HEED: You're not alone in seeking technical solutions, facing setbacks, and often tiptoeing through the minefield of successful racecar development. There are pros in the same situation. Just ask Sylvain Tremblay, whose SpeedSource race team recently completed its first season in the Prototype class of the new TUDOR United Sports Car Championship Grand Am Series.

“As the only diesel car running in Prototype, using a production-based engine and a new fuel, we're exploring new territory one race at a time,” said Tremblay, a veteran engineer and skilled race driver whose Florida-based engineering company has built and campaigned Mazda's U.S. “works” cars since the rotary-engine era.
