The company that is Racer X USA today began in 1985 and expanded to the Internet in 1999. The staff has more than 65 years of combined experience with both diesel and gas engines and power-trains, including rare high performance vehicles such as Boss 302 and 428 Cobra Jet Mustangs. The product development team at Racer X is staffed by certified automotive engineers. Racer X’s founder earned masters degrees in multiple engineering fields including automotive, aviation, hydraulic systems and structural design. Racer X’s founder and several other product development team staff members worked with James Mercer, special race vehicles project engineer for Ford Motor Company on the Ford GT 40 race cars that swept Le Mans in the 1960’s,   Also on the infamous 427 race engines and power-trains for Holman Moody’s Nascar racing divisions.  Graphics of the GT 40 have been featured on Ford and Motorcraft parts boxes, packaging and literature since the mid 1960’s.  A detuned production version of the GT 40 legal for street use was developed and sold to the public by select Ford dealers as the Ford GT through the 2010 model year.
