A prototype vehicle running Ford’s 3.5-liter EcoBoost V6 has claimed victory at the 12 Hours of Sebring last weekend. Considered to be one of the most demanding racetracks in the US, Scott Pruett, Memo Rojas, and Marino Franchitti took the Roush Yates-prepped Riley-Ford to victory lane.

Three Prototypes compete with the Ford 3.5-liter EcoBoost: The No. 01 and No. 02 race cars of Ganassi, and the No. 60 car of Michael Shank Racing. The No. 02 Comfort Revolution/Big Machine Records Riley-Ford finished sixth at Sebring after spending a considerable time out front. Also making the top-10 was the No. 60 Need for Speed Riley-Ford, which finished in ninth.

Before tackling the 12 Hours of Sebring, Michael Shank Racing also teamed up with Ford Racing and its 3.5-liter EcoBoost to break a series of closed-course speed records at the Daytona International Speedway that stood since 1987. Together, they set a new record of 222.971 mph (358.837 km/h) around the high-banked oval.
