The Air Navigation and Engineering Company (ANEC) was a British aircraft manufacturer based in Addlestone, Surrey, from 1919 to 1927, evolving from the Blériot & SPAD Manufacturing Company Limited. ANEC produced several aircraft designs, but also ventured into car manufacturing with the Blériot-Whippet cyclecar, starting production around 1920. Designed by Herbert Jones and W.D. Marchant, early Whippets featured a 1-litre air-cooled Blackburne V-twin engine and an unusual Zenith-Gradua variable belt transmission, which was later replaced by a conventional gearbox and chain drive. The company stopped production in 1927.
