The Powerdrive was a three-wheeled microcar with a rear-mounted 322 cc (20 cu in) Anzani two cylinder, two stroke 16.5 metric horsepower (12 kW) engine.The car was designed by David Gottleib, whose Powerdrive company had previously worked with the Allard Motor Company on the development of the abortive Allard Clipper. Like the Clipper, the Powerdrive was devised to exploit the lower tax rate then applicable in the UK to three wheeled vehicles weighing less than 8 long cwt (410 kg).
