In 1966 Mario Zambarbieri built a series of racing cars in the Formula Baby Junior class in Milan. It had a Fiat 500 engine in it, so he probably was struggling to get some speed. To make things a bit faster, he mounted a prepped Fiat 850 engine in the chassis between 1966 and 1968, but mounted it the other way around as in the more normal 850s.

In those years the car naturally evolved:

  • In 1966, the first series of the MZ Formula 850, it had the chassis of the MZ Formula Baby Junior and an aluminum body.
  • The 1967 version got a new tubular steel frame with a fiberglass body and the power went to 68 hp.
  • In 1968 the car got a new fiberglass body and brakes derived from the Fiat 124. To make the car a little cheaper, the power dropped to 64 hp.

One of those cars (1968 model) recently was for sale; asking price £ 12,950. Very rare so the price is probably realistic. You will also get the build sheet and the original invoice.

I spot Pirelli Cinturato's on the car, CN53's. What great tires these were on a Fiat!
