first Indy car victory. He also won the pole position for the 1987 Indianapolis 500. A year later, Rick Mears won the 1988 Indianapolis 500, the engine's first win at Indianapolis. The engine went on to have a stellar record in CART. From 1987 to 1991, the "Chevy-A" engine won 64 of 78 races. In 1992, the 265-A engine was followed up by the 265-B engine. The "Chevy-B" was fielded singly by Penske Racing (Rick Mears and Emerson Fittipaldi) in 1992 and won four CART series races. All other Ilmor teams remained with the venerable "Chevy-A" for 1992. Bobby Rahal, driving a "Chevy-A" won the 1992 CART championship, the fifth consecutive (and final) for the 265-A. Al Unser Jr. won the 1992 Indianapolis 500 driving a "Chevy-A", also the fifth consecutive (and final) Indy 500 win for the 265-A. Emerson Fittipaldi drove a "Chevy-B" to 4th place in points, but both he and Mears dropped out of that year's Indy 500 due to crashes. It was at this time that Ilmor was receiving new competition from Cosworth, which had just introduced their new powerplant, the Ford-Cosworth XB. For the 1993 season, the 265-C engine was introduced, intended to replace both the 265-A and the 265-B. The "Chevy-C" was used widespread, and produced continued success for Ilmor. Some backmarker teams continued to utilize the "A" and "B" engines during the 1993 season, but neither the "A" nor the "B" would win another Indy car race. Chevrolet dropped its badging support after the 1993 season. For the 1994 season, two new engines were introduced. The 265-D engine replaced the 265-C, although some of the smaller teams still ran the "C" throughout 1994. Without badging support, the engines were referred to simply as the "Ilmor-C" and the "Ilmor-D". The other engine introduced in 1994 was the top-secret 265-E (see below), which was actually a 3.43 liter pushrod engine, used by Penske Racing at the 1994 Indianapolis 500. For 1995, Mercedes-Benz became the badging manufacturer for the Ilmor Indy car engines. The engine continued to be a strong contender on the CART circuit. In 1996, the open wheel "split" began between CART and the IRL. Ilmor primarily was a provider for CART-based teams, and did not provide engines for any full-time IRL teams. At the 1996 Indy 500, the "Ilmor Mercedes-Benz D" was used by Galles Racing, and finished second, the powerplant's one and
