Acura is celebrating its 40th birthday by recreating its first race car, a Comptech Integra, which won back-to-back IMSA championships in the late '80s. Dubbed the Integra 40 Racer, it features a reworked 1.6-liter four-cylinder, a heavily revised chassis, and a stripped-down interior. The car was designed by Honda Racing Corporation USA and will make its debut at the Acura Grand Prix of Long Beach this year.
