Tyrrell Racing
In 1991, Ilmor entered Formula One as the engine supplier to the Leyton House team (formerly March). In 1992, Leyton House changed its name back to March and continued using Ilmor engines. Ilmor also delivered engines to Tyrrell Racing in that year. Powered by an Ilmor V10, March scored 3 points, and Tyrrell 8 points.
