Built with the body mounted upside down so it can roll while looking like it's backing up. The engine is concealed under the trunk, the V6 turbo and its piping having had to be removed. The seat Vin Diesel sat in during filming is the driver's seat, but the car is actually driven by a driver sitting in the back. The real steering wheel, accelerator and brake pedal are on the side of the car, behind Vin's seat!
