Alvis Car and Engineering Company Ltd is British manufacturing company that restarted car-making in Kenilworth UK - that originaly existed in Coventry, England from 1919 – 1967. In addition to automobiles designed for the civilian market, the company also produced racing cars, aircraft engines, armoured cars and other armoured fighting vehicles, the latter continuing long after civilian car production ceased.
The original company, T.G. John and Company Ltd., was founded in 1919 by Thomas George John (1880 – 1946). Its first products were stationary engines, carburetors and motorscooters. Following complaints from the Avro aircraft company whose logo bore similarities to the original winged green triangle, the more familiar inverted red triangle incorporating the word "Alvis" evolved. On December 14, 1921, the company officially changed its name to The Alvis Car and Engineering Company Ltd. Geoffrey de Freville (1883 – 1965) designed the first Alvis engine and is also responsible for the company name.
