Key production-based components utilized in the racing engine include block and heads, crankshaft, direct injection fuel system, valve train components, drive-by-wire throttle, alternator, sensors, fasteners, even a stock Honda oil filter.

Other variants of the same engine, the 2.8-liter HR28TT twin-turbo V6, compete in LMP2 prototype category, as well as Japan’s Autobacs SuperGT Championship, the One Lap of America competitive rally and the Pikes Peak International Hill Climb.

In the Daytona Prototype campaign, the Honda-Riley DP chassis car will be fielded by Starworks, while Extreme Speed Motorsports will continue to field a pair of HPD ARX-03b Hondas created to LMP2 specifications.
