Background: It's called Project-34 and represents an unusual approach to race car design -- six wheels, four in the front and two in the rear. The vehicle was unveiled publicly on Sunday (21 September) at Ockham, England.
It has been designed by the Elf Team Tyrrell workshops under the direction of Derek Gardner and, it tests prove successful, could make its Grand Prix racing deut in 1976.
The four front wheels operate in tandem although each is independently suspended. Furthermore, they are designed so the nims do not extend beyond the body. The wheels are smaller than normal, and have involved development of a special tyre by the Goodyear Racing Division. Their overall diameter is 16 inches (40.640 cm) and they have a 7 inch (17.78 cm) tread.
Mr. Gardner argues that while overall effective tread area is increased, drag is minimised because all four small wheels are hidden behind the "bluff" sports car nose of the vehicle. He says the design fully utilises the "narrow track-reduced drag philosophy".
He admits the new steering arrangement will make for "heavier" steering, but he says Elf-Tyrrell cars have always had unusually light steering so that even if it is slightly heavier it will still be within acceptable limits.
Behind the engine, the car remains conventional, being constructed from many parts from existing models. Its engine is a 3-litre Cosworth-Ford V8.
Gardner says the new steering arrangement could accomplish the equivalent of adding between 40 and 50 horsepower to the engine.
He also points out that the four front wheel system has the safety advantage of permitting the driver to retain control even when faced with a blowout.
Mr. Gardner has been developing the three axle concept since 1969 when he approached Ken Tyrrell during development of the first Tyrrell Grand Prix car in 1970.
