The Triumph Vitesse is a compact six-cylinder car built by Standard-Triumph from 1962 -1971. The car was styled by Giovanni Michelotti, and was available in saloon and convertible variants. The Vitesse name was first used by Austin in their 1914–16 Austin 20 (hp) and 30 (hp) Vitesse models. This was followed in 1922 by G. N.(Godfrey & Nash) on their GN Vitesse Cycle-car, and then by Triumph on a car made from 1935-1938. After the last Triumph Vitesse was made in 1971, the Vitesse name remained unused until 1982. In 1982, Rover began to use the name on their SD1 until 1986. They also used it from 1984-1990 on the SD3 216, and on the Rover 800 from October 1988 - 1991, at which time it was rebodied as the R17 version. The R17 was produced until 1998 as the Rover Vitesse Sport. Vitesse 6 The Triumph Vitesse was introduced on May 25, 1962, reusing a name previously used by the pre-Second World War Triumph Motor Company from 1936–38, and was an in-line 6-cylinder performance version of the Triumph Herald small saloon. The Herald had been introduced in 1959 and was a 2-door car styled by the Italian designer Giovanni Michelotti. Within two years, Triumph began to give thought to a sports saloon based on the Herald and using their 6-cylinder engine. Michelotti was again approached for styling, and he came up with a car that used almost all body panels from the Herald, combined with a new front end with a slanted 4-headlamp design. Standard-Triumph fitted a 1596 cc version of their traditional straight-6 derived from the engine used in the Standard Vanguard Six, but with a smaller bore diameter of , compared with the bore on the Vanguard, equipped with twin Solex B32PIH semi-downdraught carburetors. These were soon replaced by B321H carburetors due to issues with accelerator pumps. A "seam" on the cylinder block between the third & fourth cylinders reveals the design beginnings of the 803 cc Standard SC engine block, first used in the Standard Eight of 1953. The gearbox was strengthened and upgraded to closer (more sporting) gear ratios, and also offered with optional Laycock De Normanville 'D-type' overdrive with a 20% higher ratio for the top gear (the equivalent change from 3rd to 4th in a standard transmission), giving for more relaxed and economical cruising. Models fitted with overdrive had a chrome badge with
