The Frankfurt Motor Show is a strange place for the unveiling of a biofuel powered American muscle car but that in fact will be the case when Germany’s FourMotor presents its new BioConcept Mustang GT RTD at next week’s show. Though labelled a concept, the car has been raced in the Nürburgring 24-hour endurance race by former DTM driver Thomas von Löwis and is scheduled to continue competing long after the Frankfurt show closes its doors.
Powering the car is a 280hp (206kW) 2.0L four-banger developing maximum torque of 500Nm on pure bio-diesel, which is enough for it to reach a top speed of 245km/h. The car’s chassis is based on a Ford Mustang but the panels have been replaced with a new plastic shell derived from natural plant fibers developed in co-operation with Germany’s center for air and space travel.
Also on display will be a bio-diesel Volkswagen Beetle that was tested doing speeds of up to 230km/h around the Nürburgring.
