Why it matters

The Q-type was a 746 cc racing Midget whose Zoller-supercharged engine produced over 110 bhp, an extraordinary output for its size. Only eight were built in 1934, and the registry notes the chassis could not exploit the engine's full potential.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Announced two months after the P-type entered production, the Q-type relied on the P engine's development, using a short-stroke 746 cc four with a counterbalanced crankshaft and a Zoller supercharger running over 25 psi of boost. Drive went through a preselector gearbox with a clutch designed to slip under excess torque to protect the rear axle. Guarantee plates were issued between 18 May and 20 September 1934, and it was sold as a catalogue car at £550.

Identification guide

How to tell an original from a replica or later conversion.

The Q-type's body closely resembles the pointed-tail K3. It has a 7 ft 10 in wheelbase, Bishop Cam steering, 18-inch Rudge-type wire wheels, a Zoller supercharger and a preselector gearbox with a deliberately slipping two-plate clutch.
