Hersham and Walton Motors (HWM) was a racing car constructor. It is best known for its involvement in Formula One from 1951 to 1955. HWM owners George Abecassis and John Heath started a racing team in 1946 with an Alta-engined car and called it an HWM, after their garage, based in Walton-on-Thames, England.
Besides Formula One, the team was also involved in sports car racing, and also used Jaguar engines. John Heath was killed on the 1956 Mille Miglia in Italy. Abecassis discontinued the team soon after.
Hersham and Walton Motors continues to this day as an Audi and Aston Martin dealership.
