2007 Honda Indy V-8 Engine:
- Honda's engine for the 2007 IRL IndyCar Series is designated the HI7R Series Indy V-8. This engine is a development of the two-time IRL Manufacturers' Championship winning design created in partnership with Ilmor Engineering.
- For the 2007 season, a 3.5-liter engine (213.6 cubic inches of displacement) will provide a longer service life between rebuilds, reducing the cost of racing for IndyCar teams. In addition, it will provide increased mid-range torque for the varied IndyCar Series schedule.
- Honda won its first Honda IndyCar Series Racing title in 2004, winning 14 of 16 events. Kanaan was the drivers' champion with three wins, followed by teammate Wheldon, also with three victories. Rahal Letterman Racing's Buddy Rice was third in the championship with three wins, including the Indianapolis 500. Fernandez Racing owner/driver Adrian Fernandez was another three-time race winner, and teammate Kosuke Matsuura was both Indianapolis 500 and IndyCar Series Rookie of the Year.
- The 2007 engine will be used by all teams in the 2007 IndyCar Series, with technical support provided by both Honda Performance Development and Ilmor Engineering, Inc.
