Devon Motorworks was an American car brand based in Los Angeles, California founded in 2008 by entrepreneur Scott Devon. Devon's initial production vehicle, the Devon GTX supercar, was scheduled to begin production in early 2010, however, the economic downturn shelved production.

Devon Motorworks made news for being the single bidder for Chrysler's Dodge Viper platform, originally intended to provide the basis for the Devon GTX. The bid was, however, rejected by Chrysler for being below the US$10.0 million reserve and with the fourth-generation Viper upon which the GTX was derived being discontinued, Devon Motorworks was closed.

The initial product, Devon GTX, was unveiled in 2009 Pebble Beach Concours d’Elegance. The vehicle was conceived by Swedish designer Daniel Paulin and Devon Motor Works Founder Scott Devon, who shared a vision for an American supercar that combined classic and contemporary design cues.

The distinguishing features of the Devon GTX included an aircraft-quality carbon fiber body, “up and forward” articulating doors, two-tone wheel surrounds, minimal front/rear overhangs, dual center exhaust ports, and carbon fiber racing seats.

Two GTX cars were completed before production ceased, with one selling for $220,000 at a Barrett-Jackson auction in 2012.
