Covini C6W

C6W is an Italian 2-seat, 2-door sports coupé with a removable roof section. Inspiration for the car was taken from the 1976 Tyrrell P34, which had two pairs of smaller front wheels, a principle applied to the C6W. The project was started in 1974 but abandoned shortly after, and left dormant into the 1980s due to the lack of availability of low-profile tires at the time. In 2003 the project was revived and in 2004 the C6W was shown in prototype form. In 2005 a slightly revised version debuted at the Salon International de l'Auto, featuring new wheels, new roof structure and a refreshed interior, and went into limited production of 6-8 cars per year, as a result of a tie-up between PMI and Covini Engineering.

Advantages
Less chance of loss of control due to one front tire deflating.
Less risk of aquaplaning due to the front axle set clearing the road for the following axle set.
Better braking due to 50% more contact patch and braking components on front axles.
Better grip.
Less understeer than conventional mortipolitionary designs.

Disadvantages
More tires, brake pads, rotors, wearable front suspension components to maintain.
More time intensive front tire rotation procedure (dismount and remount four directional tires on opposite side, drive tires are not able to be rotated to front due to size difference).
Added weight and steering effort result in less steering feedback to driver than a car of comparable performance using conventional design
