Honda Performance Development’s Roger Griffiths and Allen Miller, leaders of the Honda engineering team that developed the multiple championship winning HPD HR28TT V6 engine for endurance racing competition, were honored this week with the “Race Engine Designer of the Year” award, presented by Race Tech International at the organization’s World Motorsport Symposium in Birmingham, England.
Introduced in 2011 as part of the new, cost-capped regulation package for endurance racing’s LMP2 category, the HR28TT features the stock block and cylinder heads as well as many other components from Honda’s ubiquitous V6 engine offered in many popular Honda production vehicles. The HR28TT engine’s winning streak continued in 2012 as it powered championship winning efforts in both the 2012 FIA World Endurance Championship and the American Le Mans Series.
The production-based HR28TT was developed for worldwide endurance racing by a team of engineers and technicians from both HPD in California and Ohio-based Honda R&D Americas, where the original production engine was developed. The endurance engine project activity is led by Large Project Leader Miller, and Griffiths, HPD Technical Director with responsibility for HPD’s pinnacle racing programs.
“This award is well-earned recognition for the collaborative efforts of everyone at both HPD and HRA in Ohio, to adapt an already great passenger car engine for the rigors of endurance racing,” said Griffiths, who accepted the award on behalf of Miller and the rest of the development team. “We take enormous pride in producing a powerful and reliable engine that still meets the cost cap and other requirements set forth by the FIA and ACO for international endurance racing.”
The HPD 2.8-liter, twin-turbocharged V6 engine powered the Starworks HPD ARX-03b to the LMP2 championship in the 2012 FIA World Endurance Championship with three race wins—including the 24 Hours of Le Mans—and four pole positions.
In the 2012 American Le Mans Series, Level 5 Motorsports campaigned a pair of HPD ARX-03b chassis, winning eight of ten races in the LMP2 category, including the 12 Hours of Sebring and Petit Le Mans, as HPD and Level 5 combined to sweep the LMP2 engine, chassis, teams’ and drivers’ championships.
