Covini C6Wheels

Ferruccio Corvini developed the C6Wheels. He chose 6 wheels for guaranteed vehicle control in case of a front tire deflation. Of course, the list of reasons why to select six wheels continues. Four front disc brakes, although a smaller single area, ensure a greater braking surface, low risk of aquaplaning due to the two foremost wheels, which wipe the water of the ones behind them, ensuring a better road-holding and also comfort is a consequence of more evenly distributed reaction forces in the suspension. Two additional springs and dampers provide a better handling for the vehicle. The model features an 8-cylinder, 4-valves, naturally aspirated engine with a 4.200 cc capacity that is capable of delivering 380 PS and 450 Nm of torque. It uses a rear wheel drive transaxle and it has steel tubular with carbon fiber reinforcements and structural parts chassis. It can reach a top speed of 300 km/h.

The original idea was conceived by Ferruccio Covini in '74 and made provision for 10 inches front wheels because there where no low profile tyres at the time. The project was ditched in favour of the Soleado prototype, deemed more important, and lay dormant until the 80s when hydro-pneumatic suspension for the four front wheels where devised to optimise weight distribution under various loading conditions. High development costs and other contingencies forced the project to be delayed again. Its use of new ABS technologies and airbags in the 90s pointed in the direction of new research into active and passive safety. This aspect encouraged backing from companies for its development..

Why six wheels?

-in case of a front tyre deflation, the vehicle control is guaranteed by the other wheel next to it.
-four front disc brakes, although a smaller single area, ensure a greater braking surface; this
means less overheating and a higher brake effort
-low risk of aquaplaning, due to the two foremost wheels, which wipe the water for the ones
behind them, ensuring a better roadholding
-comfort is a consequence of more evenly distributed reaction forces in the supension: the
reaction in case of a pot hole is divided between the four front wheels and the shudder in the
chassis is limited.
-reduced unsprung weight in the wheels improves the grip. Directional stability is improved: a
change of angle due to slack in the steering mechanism (in stuctures like silentblocks) is
compensated by the second set of wheels.
-two additional springs and dampers provide a better handling for the vehicle.
