Panther 6
This strange car is considered a supercar due to its power, price, and unusual technical solutions like having six wheels instead of the usual 4. The Panther 6 was a roadster powered by a monstrous 8.2-liter V8 engine from the Cadillac Eldorado. The enormous engine was placed behind the cabin and powered the rear wheels while four wheels in the front managed the steering. To achieve proper ride height and save space in the front where the double suspension assembly is, designers installed smaller diameter wheels compared to much bigger ones on the back (via PCC).
The Panther 6 was an extravagant convertible supercar with a leather interior, climate control, power windows and doors, and even a TV and phone. The designers claimed it was capable of achieving a top speed of 200 mph (320 km/h), but automobile experts were skeptical, and Panther never allowed independent testing. Only two cars left the factory in England.
