Half separate model and half offshoot of the C8 is the C12. This is similar to the C8 is most ways, but the mid-mounted engine is a 6.0-liter W12, the same one that has been found under the hoods of the Bentley Continental, Audi A8 and Volkswagen Phaeton, to name but a few. This produces 500 hp, and a bigger fuel tank is fitted for the thirstier engine. The appearance of the car remains the same, with the exception of the C12 Zagato, which is a different model altogether. A race version was even dreamed up, and two cars were built. These raced at the 24 Hours of Le Mans, as well as other endurance races.
