Ilmor is a British independent high-performance motor racing engineering company. It was founded by Mario Illien and Paul Morgan in November 1983. With manufacturing based in Brixworth, Northamptonshire, and maintenance offices in Plymouth, Michigan, the company supplies engines and consultancy to the IndyCar Series and MotoGP.

The company originally developed IndyCar engines under the Chevrolet banner. In the 1990s, the company built a partnership with Mercedes-Benz to power F1 cars for both the Sauber and McLaren teams. After the death of Paul Morgan in a vintage aeroplane crash in 2001, Mercedes increased its stake until it owned the entire company, and renamed it Mercedes-Benz High Performance Engines Ltd. In 2005, Mario Illien concluded a deal to purchase the Special Projects part of the company in partnership with Roger Penske, which worked in partnership with Honda Performance Development for IndyCar engines between 2003 and 2011.^[1] This new company, which is independent of Mercedes, is once again known as Ilmor Engineering Ltd. They developed the Ilmor X3 for the 2007 MotoGP World Motorcycle Championship, entering one race before withdrawing and effectively shutting down the race team, due to funding problems.

Racing remains the core part of the business today and Ilmor acts as a consultant for motorsport clients from all forms of racing. However, the business is now using its racing expertise to diversify into other areas such as OEM automotive, defence, marine and energy efficient engine applications.
