Background

The Toyota Indy V8 is an all-new engine designed from a "clean sheet of paper" for competition in the Indy Racing League (IRL) IndyCar Series beginning in 2003 although not closely resembled to Toyota RV8 series engines. The 3.5-liter, naturally aspirated power plant would make its' racing debut in the 2003 season-opening Toyota Indy 300 at Homestead-Miami Speedway in March. The Toyota Indy V8 was designed, built and developed by Toyota Racing Development (TRD), U.S.A. in its 47,000 square-foot Costa Mesa, Calif., facility. Dynamometer testing began in February 2002, and the engine was tested in a race car for the first time in July 2002.

Design of the Toyota Indy V8 draws heavily on experience gained with Toyota's successful CART racing engines. The high-rpm, turbocharged engines earned 21 victories and 23 pole positions from 1999 to 2002, including the CART FedEx Championship Series Driver's (Cristiano da Matta) and Manufacturer's Championships in 2002. The Toyota RV8F and its predecessor, the Toyota RV8E (used in competition in 2000) are the only American-designed and built engines to win in CART competition during the past 22 years.

Following the 2005 IndyCar Series, Team Penske and Target Chip Ganassi Racing announced they would switch to Honda engines, leaving Toyota with no championship contenders. As a result of this and their intent to re-allocate resources for NASCAR, Toyota announced they would leave the IndyCar Series prematurely during the off-season.

Championship Auto Racing Teams (CART) was a sanctioning body for American open-wheel car racing that operated from 1979 until dissolving after the 2003 season. CART was founded in 1979 by United States Auto Club (USAC) Championship Division team owners who disagreed with the direction and leadership of USAC, with the then-novel idea of team owners sanctioning and promoting their own series collectively instead of relying on a neutral body to do so. Through the 1980s, CART's Indy Car World Series became the pre-eminent open-wheel auto racing series in North America, featuring street circuits, road courses, and oval track racing. CART teams continued to compete at the USAC-sanctioned Indianapolis 500, which was effectively integrated into the series schedule.
