|July 1980 Road & Track|
Another 6 wheel experiment from the seventies, this time by Roy Lane, who converted the March 771 race car into a 4 wheel drive hill climb race car. He had fitted the two axle gearbox from the aborted March 761 F1 project. Apparently it worked well in wet conditions but in the dry broke gears and had traction and handling issues. The 4wd system also took a lot of horsepower. It was thought that a differential was needed between the rear axles to allow them to operate independently. The car was soon converted back to 4 wheels. Car history here.
