Ilmor realized that this provided scope for a completely new pure-bred racing engine – it would need to retain pushrods, but could be designed specifically for the requirements of the Indianapolis 500, and in strict secrecy schemed a completely new V8 engine which was approximately more powerful than the Cosworth XB and Ilmor 265D opposition. Team Penske's cars were by far the fastest at the 1994 Indianapolis 500, and Al Unser Jr. won the race, with Emerson Fittipaldi also figuring strongly until an accident on lap 184. The loophole was closed for 1995, and Penske, a year behind on development for Indy, failed to qualify their 265D-powered cars for that year's 500.
