Background
First introduced in 1962, the Michelotti - styled Triumph Vitesse became a staple of Standard-Triumph’s lineup throughout the 1960s, and went through numerous engine, chassis and minor styling changes throughout its nine-year tenure.
Marketed as an inline-six, performance-focused derivative of the Triumph Herald saloon, the Vitesse was available in both convertible and saloon form. Initially powered by a 1.6-litre (1596cc) version of the inline-six used in the Standard Vanguard Six, the engine had reduced-diameter bores, twin Soles semi-downdraught carburettors and a four-speed gearbox with synchromesh on all but first gear, and optional overdrive on fourth.
In September 1966, the Triumph Vitesse 2-Litre was introduced, with an enlarged 2-litre engine in line with that of the Triumph GT6 coupé. Power was increased to 95bhp, along with the fitment of a stronger clutch, an all-synchromesh gearbox, larger front brakes and a stronger differential, though criticisms remained about the Vitesse’s swing-axle rear suspension system, which struggled to cope with the power of the original 1.6-litre engine, let alone the larger 2.0-litre offering.
In a last-ditch attempt to combat these issues, and to upgrade the Vitesse range as a whole, the MK2 model was introduced in October of 1968. Featuring the same engine found in the earlier 2-Litre model, the rear suspension setup retained its swing-axle setup, but was fitted with new lower wishbones and Rotoflex half-shaft couplings, which went a long way towards taming the wayward handling of the Vitesse.
Elsewhere, the engine was once again tweaked to squeeze out more power from the 2.0-litre inline-six, with a new peak power figure of 104bhp, new Stromberg 150 CDS carburettors, and a minor exterior redesign saw a new grille, Rostyle wheel trims, and numerous other styling revisions.
Unfortunately, it proved too little, too late for the Vitesse, eventually being phased out during 1971, to pave the way for the new Triumph Dolomite to take its place.
