- Vitesse 6 / 1600
- May 1962 – September 1966. 1,596cc straight six, 70bhp, about 84bhp from 1965. 31,261 built — 22,814 saloons, 8,447 convertibles. 679 convertibles went to America badged Sports 6.
- Vitesse 2-litre
- September 1966 – September 1968. 1,998cc, 95bhp. 10,830 built — 7,328 saloons, 3,502 convertibles.

- The Mk2 rear suspension
-
Early cars: Herald swing axle on a transverse leaf spring, about 15 degrees of camber change. Mk2, 1968: reversed lower wishbones and Rotoflex rubber couplings, double-jointed driveshafts, relocated trailing arms — camber change down to about 5 degrees. Nothing crosses between the two.
- Brakes
-
Front discs standard on every Vitesse, where the Herald had them optional until the 12/50. Rear drums are larger than the Herald’s.
- Gearbox
-
1600 and early 2-litre: no synchromesh on first. Mk2: all-synchromesh. Overdrive standard, where the Herald had it optional.
- Chassis
- Substantially redesigned and strengthened over the Herald’s, especially around the differential mountings. Not a Herald chassis.
- Shared with the Herald
- The separate-chassis concept, most body panels, the forward-hinging one-piece front end, the front suspension layout and the rack and pinion steering.
- Not shared
- Engine — four versus six. The strengthened chassis. The four-headlamp front panel. Standard front discs. Larger rear drums. Standard overdrive. And the entire Mk2 rear end.
- Sister car
- The GT6 Mk2 got the same Rotoflex fix at the same time, and the GT6 uses the Vitesse’s 2-litre six.
