This isn't new I've seen this years ago, and the car is still pushing, I dought that it will ever become excepted.

Yeah they're from the 70s and the wikipedia page mentions other attempts of making similar cars. They had a F1 with 4 wheels at the back as well, 2 in the front. Pitstops would be a bit more work though.

I used to drive one of these when I was a kid. Only 6 wheeler I ever knew of.
