The Blériot-Whippet was a British 4 wheeled cyclecar made from 1920 to 1927 by the Air Navigation and Engineering Company based in Addlestone, Surrey.

The most unusual feature of the car was its infinitely variable belt transmission using expanding pulleys to a design called the Zenith-Gradua.

Power came from a 1 Litre, Blackburne air-cooled, V-twin, engine producing 14 bhp (10 kW) at 2000 rpm[1] and mounted with cylinders one behind the other.

[3] Two seat open bodies were standard made of plywood covered in leather cloth and came in tourer and sports versions.
