Honda Performance Development, the racing arm of American Honda Motor Co., Inc., is continuing its commitment to customer LMP1 endurance sports-car racing with the 2014 introduction of an all-new, turbocharged V6 engine, to be followed in 2015 by a range of bespoke energy recovery options, for FIA World Endurance Championship competition.
After several successful seasons supplying the normally aspirated Honda LM-V8 engine to private teams in both the WEC and American Le Mans Series, HPD engineers and designers made the decision to offer their partner teams access to updated technology, which the company believes will be necessary to successfully compete on the world stage, under the ACO's new LMP1 energy-based power train regulations.
The new engine, to be designated the Honda HR22T, is based on the same architecture used in the Indianapolis 500-winning, 2.2-liter direct injection turbocharged V6 engine used in IZOD IndyCar Series competition since 2012, designed to be coupled with a new energy recovery system developed in concert with HPD technical partner Magneti Marelli.
"This is an exciting new program for HPD and our customer teams in the World Endurance Championship, as it brings manufacturer-level engine technology to privateer teams," said Steve Eriksen, HPD Vice President and COO. "A small-displacement, direct injection, turbocharged engine with a range of energy recovery options will provide private teams with the technical sophistication they need to compete under the challenging new LMP1 regulations."
A completely revised rules package being introduced for the WEC in 2014 opens the door for HPD to introduce this new powertrain system, specifically tailored to meet the needs of private teams engaged in top-level endurance sports-car racing competition.
Starting in 2014, rather than any set engine displacement or air inlet restrictor limits, the technical regulations for the series will specify a maximum fuel-flow rate into the engine, with or without energy recovery systems.
"The new rules say that if you are a private team, you can either run without energy recovery systems or choose to add the level of energy recovery that best suits your needs. This will allow our customers to choose the ERS solution that meets their needs – everything from no energy recovery up to the full eight Megajoule maximum," Eriksen said. "This new regulation direction that is more conscious of environmental technologies will encourage HPD to participate from the perspectives of both developing future technologies and nurturing engineers."
HPD's highly successful LMP2 program will likewise continue in 2013 with the cost-capped ARX-03b chassis and production-based Honda HR28TT twin-turbocharged direct injection V6 engine, the only engine in its class to feature such production-relevant technology.
The engine/chassis package remains eligible to compete in both the WEC and the newly combined United Sports Car Racing series in North America.
In addition to the new engine and its energy recovery system, HPD and chassis technical partner Wirth Research are also developing a coupe version of the successful ARX chassis series that will provide a fully integrated solution for the new V6 Honda powerplant and ERS.
Located in Santa Clarita, California, HPD is the technical operations center for high-performance Honda racing cars and engines. For more information, visit hpd.honda.com.
