Two high-powered Ford concepts are flex-fuel capable

Ford is showing off at least two major high-powered concept cars at next weeks Detroit Auto Show, both based on stretched versions the Ford Mustang platform. The Ford Interceptor and Lincoln MKR both have engines with 400+hp engines, a 5.0L twin-cam V-8 in the Interceptor and a twin-turbo 3.5L V-6 in the MKR. The reason these two cars are here on this page is because both are flex-fuel capable, being able to run on any mix of gas or ethanol up to E85. Green machines, no?
