About Sylvain Tremblay
Born 1965. Sylvain Tremblay is a Canadian racing automobile driver.
Sylvain Tremblay (born 9 August 1965) is a Canadian racing driver and team owner who last competed in the United SportsCar Championship for SpeedSource. He founded the team in 1995, and primarily raced Mazda machinery in the Rolex Sports Car Series before running the factory Mazda Prototype from 2014 to 2017.
Career Born in Montreal, Tremblay began his racing career at the age of 16, primarily racing in SCCA-organized events in his early career. In 1995, Tremblay founded SpeedSource Race Engineering in South Florida to primarily field Mazda machinery in SCCA competitions and the Speedvision Cup. After finishing third in the GS class of the 1997 IMSA Speedvision Cup, Tremblay was third in the GT3 class of the 1999 24 Hours of Daytona for G & W Motorsports, as well as also finishing third in the GT class of the 12 Hours of Sebring for the same team later that year.
Following a part-time campaign in the BMG Motorola Cup the following year, Tremblay returned to the series full-time for 2001, racing for his SpeedSource team aboard a Porsche 911 GT3. In his first full season in the series, Tremblay won seven of the season's ten races to secure the GS title. Two more seasons in the series then ensued, in which he dabbled across three classes, before a title-winninig campaign in the ST class in 2004, driving a Mazda RX-8. During 2004, Tremblay also raced part-time in the Rolex Sports Car Series for his own team, fielding a Multimatic MDP1.
Remaining in the Grand-Am Cup to defend his title the following year, Tremblay scored five wins as he ended the year runner-up in points. Another season in the Grand-Am Cup then ensued, in which he finished fifth in points with two podiums to his name, a year in which he also returned to the Rolex Sports Car Series, scoring a GT class podium at Miami in his RX-8. Switching to the latter full-time for 2007, Tremblay won in Mexico, Miami and the second Daytona enduro to end the year sixth in the GT standings. Continuing in the series for 2008, Tremblay scored class wins at both Daytona enduros and Barber en route to a third-place points finish. A third full-time season in the series then ensued, in which Tremblay scored a lone win at Laguna Seca, a repeat pole at Daytona and three other podiums to take fifth in the GT standings.
In 2010, Tremblay had his most successful year in the series, as he won the 24 Hours of Daytona, the New Jersey enduro and took three other podiums to secure runner-up honors in the GT class. The following year, Tremblay scored a lone win in New Jersey and three other podiums to take third in points, and then following that up with a win at Barber and three podiums in 2012 to finish fourth in points. With the addition of the GX class in 2013, Tremblay and SpeedSource moved to the class, fielding a diesel-powered Mazda6, scoring four wins and standing on the podium in all but one race en route to a third-place points finish as Mazda clinched the Manufacturers' title.
Following the demise of the GX class and the merger between the Rolex Sports Car Series and the American Le Mans Series in 2014, SpeedSource joined the newly-created United SportsCar Championship, running a pair of works Mazda SKYACTIV-D LMP2 cars in the premier Prototype class. After a full season yielded 12th in points and a best result of seventh at Laguna Seca, Tremblay only drove the endurance rounds in 2015, with non-finishes at Daytona, Sebring and Petit Le Mans. Tremblay then primarily focused on the management of his team, which continued being Mazda's factory team in its DPi endeavours until mid-2017, when the program was stopped with immediate effect after Joest Racing was announced to be taking over for the following year. In December of that year, SpeedSource ceased operations and sold all of its equipment.
