Allison Transmission Holdings Inc. has announced a sponsorship of CFH Racing for the two Verizon IndyCar Series events at the Indianapolis Motor Speedway in May, including the Indianapolis 500.

Allison will appear on the No. 20 car, which will be driven by two-time defending Indianapolis 500 pole winner and three-time IndyCar race winner Ed Carpenter for the 99th running of the Indianapolis 500 on May 24. Allison also will appear on the No. 20 car driven by Luca Filippi for the Angie’s List Grand Prix of Indianapolis on May 9

“Joining with CFH Racing is a natural way for Allison to continue celebrating its 100th anniversary in 2015,” said Lou Gilbert, director of North American marketing and global brand development for Allison Transmission. “Our company’s heritage is strongly tied to both the Indianapolis Motor Speedway and the Indianapolis 500.”

Allison traces its corporate lineage back to the founding of the Indianapolis Speedway Team Co. on Sept. 14, 1915. As a co-founder of the Indianapolis Motor Speedway and part owner of several racing teams, James A. Allison, a prominent entrepreneur, innovator and businessman, established a precision machine shop and experimental firm on Main Street in Speedway called the Allison Experimental Co. to support his racing endeavors. As a race team owner, Allison won the 1919 Indianapolis 500 mile race with driver Howdy Wilcox.

“We’re honored that Allison Transmission chose to celebrate its centennial with CFH Racing,” said team co-owner and driver Ed Carpenter. “In addition to producing world-class products, they are great neighbors and supporters of the community. We are thrilled to be involved with Allison’s customers and employees over the next two months.”

On-track activity at the Indianapolis Motor Speedway will begin May 3.
