Meanwhile,
back in 1959 and the introduction of the Herald, any number of new models, projects and
prototypes were being considered by Standard-Triumph. One of these was an engine project
-- a six-cylinder engine derived from the SC/Herald engine (the engine that ultimately was
to power the 2000 and TR6 models). By 1960, Triumph engineers had shoehorned a 2-litre
version of this six into a modified Herald Coupé. The concept caught on, at least within
the Triumph organization. No one expected sales to be exceptional, and the cost to bring
the car to production was fairly low, so the car looked to be profitable. Major changes
from the original Herald involved new front styling from Michelotti and a reworked,
sturdier chassis frame ( later adapted on Heralds as mentioned above ). When the Vitesse
was launched in 1962, it featured a 1600cc engine rather than the 2000cc engine of the
first prototype, and the car was offered only in Saloon and Convertible versions. Lagging
sales of the Herald Coupé were to blame for the lack of a Coupé in the Vitesse range. In
1965, the substitution of Stromberg sidedraft carburetors and manifold from the 2000 for
the original Solex setup resulted in a significant gain of horsepower, acceleration and
fuel economy.
By
1966, the Vitesse had been significantly upgraded in the face of increased competition,
primarily in sharing a 95hp, 2- litre motor and other components introduced in the new GT6
, all-synchromesh transmission (developed originally for factory Spitfire rallye cars),
sturdier axles and differential, larger front disc brakes, and the 4.5" wide wheels
used on Courier, GT6 and 2000 models.
By this time, though, the limitations
of the swing-axle rear suspension were noted more and more both in the Vitesse and GT6.
Although the now-familiar swing-spring fix had been around since the beginning of the
Herald line in 1959, it was not applied until 1971, and then only to the Spitfire.
Instead, a double- jointed half axle setup was designed, utilizing the same transverse
spring but adding a lower wishbone and rotoflex couplings and relocating the trailing arm
and shock absorbers (now lever type on the Vitesse). The Vitesse 2-litre Mk. 2, introduced
in late 1968, incorporated this change along with a further increase in horsepower, gained
from a different camshaft and use of the "full-width" cylinder head. (The GT6
Mk.2 -- or GT6+ in North America -- also shared these improvements.) As good as the car
now was, though, it was perhaps a bit late in coming. Sales tapered off steadily; the last
Vitesse was built in May 1971, only weeks before Dolomite production began.
