Allard, better known for light sports cars, produced a pilot run of around twenty fibreglass-bodied three-wheeled Clipper microcars in 1953–54.

[7] The Clipper's lightweight body and small engine contributed to its weight of just 6 long cwt (300 kg), with a claimed fuel consumption of 70 mpg‑imp (4.0 L/100 km; 58 mpg‑US).

[9] After testing a prototype against two other UK three wheelers, a Bond and an AC Petite, an agreement was made with Encon Motors to manufacture the Clipper at their workshop in Fulham.

Production problems with the fibreglass body required new moulds to be made, which incurred additional costs which could not be agreed,[10] and the project was cancelled in 1954.

Cooling difficulties and driveshaft weakness made the Clipper very unreliable, to the extent that motoring writer Giles Chapman rated the car at No.
