Honda unveils 3.5-liter prototype engine to be used in United SportsCar Championship
The new engine will debut at the 12 Hours of Sebring event

Honda Performance Development Thursday announced a new, 3.5-liter racing application for the versatile, production based Honda V6 engine found in a wide range of Honda/Acura passenger cars and light trucks and now raced in multiple categories worldwide.

The Honda HR35TT twin-turbocharged V6 is expected to make its United SportsCar Championship debut at the 2014 Mobil1 12 Hours of Sebring, mounted in a Riley Gen3 prototype chassis campaigned by Starworks Motorsport.

Previously, Starworks partnered with HPD to win the LMP2 class at the 24 Hours of Le Mans and World Endurance Championship in 2012, using HPD’s ARX-03b chassis and Honda HR28TT twin-turbocharged V6, which also is derived from Honda’s J35 series of engines.

Starworks becomes the second team to utilize Honda power for the new United SportsCar Championship. Extreme Speed Motorsports campaigns a pair of prototype class HPD ARX-03b Hondas, after a successful initial season with the same package in the 2013 American Le Mans Series.

“This is an exciting program for HPD and our customer teams in the United SportsCar Championship,” said Steve Eriksen, HPD Vice President and COO. “Adding Starworks, a team that achieved great success with us in 2012, in a prototype machine alongside the proven HPD-Honda combination run by Extreme Speed Motorsports provides HPD with a strong, balanced attack in the inaugural United SportsCar Championship.”

“It’s a fantastic feeling to be partnering with Honda once again,” said Starworks team owner Peter Baron. “No doubt we had amazing success with HPD in 2012, but unfortunately it was only a one-year program. We have had numerous conversations over the past two years about building a Daytona Prototype motor, and we’re thrilled to see it come to fruition. We absolutely love working with HPD and have been in collaboration to find a new opportunity to partner with them again. We will have our work cut out with the steep learning curve to get us to victory lane, but HPD brings determination and success to every program it touches. Although HPD already competes in the Prototype class, we feel this is huge step for the United SportsCar Championship series, and Starworks is thrilled to be part of it.”

Honda To Go Daytona Prototype Racing

Honda is joining the likes of Ford and Chevrolet in the manufacturer ranks of the Daytona Prototype (DP) class of the TUDOR United Sports Car Championship. The automaker has confirmed that its new  Honda Riley DP package, powered by a new twin-turbocharged version of its familiar 3.5-liter V-6, will be run by Starworks Motorsport at the Sebring 12 Hours this weekend.

Key components shared between the racing version of the engine and the production unit include the block and heads, crankshaft, direct injection fuel system, valve train components, drive-by-wire throttle, alternator, sensors, and fasteners. The engine even utilizes a stock Honda oil filter.

The automaker isn’t exiting the LMP2 class though, with Extreme Speed Motorsports set to continue fielding a pair of Honda-powered prototypes in the LMP2 class, which features fellow manufacturers Nissan and Mazda. This combination results in an impressive five-manufacturer lineup vying for Prototype honors in the TUDOR United SportsCar Championship this season.

"Adding a Daytona Prototype effort alongside the proven HPD-Honda chassis and engine combination in LMP2 provides Honda with a strong and balanced attack in the inaugural TUDOR Championship," Honda Performance Development boss Steve Eriksen said in a statement.  "This is a great opportunity for HPD and our customer teams in the TUDOR United SportsCar Championship."
