The Panther 6 was a British six-wheel convertible produced by Panther in 1977. The car is powered by a mid-mounted 8.2 L (500 cu in) Cadillac V8 engine with twin turbochargers paired to a three-speed automatic transmission. Only two cars were made (one in black, one in white), both of which are known to still exist.
The six-wheel configuration was inspired by the Tyrrell P34 racing car. The layout consists of one pair of larger rear wheels with Pirelli 265/50VR16 tyres, and two pairs of smaller steerable front wheels with Pirelli 205/40VR13 tyres. This concept of the Panther Six was considered an early masterpiece of a true supercar.
The specification included a detachable hard top and convertible soft top, electronic instruments, air conditioning, an automatic fire extinguisher, electric seats and windows, a telephone and a dashboard-mounted television set.
Claims for the top speed of this vehicle suggested it was capable of over 200 mph (322 km/h); however, these claims are unsubstantiated as neither were ever seriously test driven at the time.
