Reynard Motorsport
The 2.65 liter turbo V8 Ford-Cosworth XFE engine continued to be the exclusive power plant for the series. Bridgestone continued on as the exclusive series tire supplier as well. The two companies continued the marketing agreement that branded the series "Bridgestone Presents the Champ Car World Series Powered by Ford". All teams ran the Lola B02/00 chassis after the 2002 bankruptcy of Reynard Motorsport prevented further development of their Reynard 02I, causing it to become uncompetitive against the Lola.
