Penske Racing and Toyota Motor Sales U.S.A. announced Tuesday that Penske will join Indy Racing League competitor Kelley Racing in using the engines that will debut next season.
Penske, the winningest team in American open-wheel racing with 111 race wins and 11 championships, switched from the CART series to the IRL this season and is currently using Chevrolet engines.
Toyota, which is currently furnishing engines for the CART series, will also switch to the IRL next season.
