Tui
Alan McCall was a respected mechanic at McLaren when he produced the Tui F3 car in 1970, Tui is the name of a small bird from McCall’s native New Zealand. In 1971 a Formula B car was built which acted as base for the 1972 F2 car which Dave Morgan and John Watson showed had some promise. McCall then became involved in building the tub for the Tecno F1 project. The Tui was then converted to run in the North American F Atlantic but without great success and after this Tui were not seen again.
1970
The Tui AM1 consisted of an aluminium monocoque with outboard suspension, the Broadspeed engine acted as a stressed member. Many of the parts used were ex-McLaren including the wheels, uprights and windscreen.
Wheelbase: 84.5 ins.
Track front: 54 ins. Rear: 56 ins.
Bet Hawthorne showed the car had potential but like many of the smaller teams with no budgets getting hold of a decent engine was a problem. The best finish for the AM1 was a fourth in a Lombank round at Brands Hatch.

1964
The pictures of the 1964 Abarth F3 indicate that the chassis was the same as that used for the F2 design, in addition track and wheelbase dimensions were virtually identical. It was a conventional spaceframe design with wishbone-based outboard suspension front and rear. Front track was 1320mm, rear 1330mm, wheelbase 2300mm and the chassis weighed 400kg. The engine was a 982cc Fiat-based unit with a four-speed gearbox, a Weber 40DCD carburetor was used and power was quoted as 88bhp at 7900rpm.
For whatever reason, perhaps the F3 engine wasn’t up to the job, the Abarth never raced.
