Allison will appear on the No. 21 Ed Carpenter Racing Chevrolet driven by Josef Newgarden for the grand prix on the IMS road course and on the No. 20 Chevy driven by two-time Indianapolis 500 pole winner and team owner Ed Carpenter for the Indianapolis 500.
Allison's corporate lineage goes back to the founding of the Indianapolis Speedway Team Co. on Sept. 14, 1915. As a co-founder of IMS and part owner of several racing teams, James A. Allison, a prominent entrepreneur, innovator and businessman, established a precision machine shop and experimental firm near the fabled racetrack on Main Street in Speedway, Ind., called the Allison Experimental Co. to support his racing endeavors. As a race team owner, Allison won the 1919 Indianapolis 500 with driver Howdy Wilcox.
"We're thrilled to be involved with Ed Carpenter Racing and the historic 100th Running of the Indianapolis 500," said Lou Gilbert, director of North American marketing and global brand development for Allison Transmission. "In celebration of our shared heritage with the Indianapolis Motor Speedway and both of our recent centennial milestones, we're proud to support our hometown race team for a second consecutive year."
