Take one racing-tuned Ford Mustang, add a dollop of environmentally sensitive pretense and what do you get? If you said Steve McGreen, give yourself a slap. If you said the BioConcept Mustang GT RTD you were obviously looking over our shoulder. Ford's bringing the biodiesel-powered racer to the Frankfurt show next week. Under the hood, there's a 2.0-liter, 280-horsepower oil burner producing 369 foot pounds of torque. The plastic body shell was derived from natural plant fibers, in partnership with Germany's aerospace center, and top speed is in range of 152 mph. And it's not just a green trailer queen. The Mustang BioConcept has apparently already withstood the Nürburgring 24-hour endurance race, with former DTM driver Thomas von Löwis at the wheel. [Auto Motor und Sport via Motor Authority]
