The Jaguar S-Type is a saloon car that was produced by Jaguar Cars in the United Kingdom from 1963 to 1968. The S-Type was introduced as a replacement for the Mark 2, and was based on a shortened version of the Mark X platform. It shared its engines with the Mark X, until 1967 when it received new V8 engines.
The S-Type was available with 3.4 litre (3409 cc), 3.8 litre (3781 cc) and 4.2 litre (4235 cc) versions of Jaguar's straight-six engine, as well as new V8 engines of either 4.2 litres (4230 cc) or 5.3 litres (5343 cc). All except the last used twin SU carburettors; US models were fitted with Strombergs until 1971 when they switched to Rochester Quadrajets due to emissions regulations.. A Borg Warner Type 35 automatic transmission was standard equipment except on early 3.4 models which had an overdrive manual gearbox option; all others had three-speed automatics from 1965 onwards.. From October 1966 an optional Borg Warner Model 8 four-speed manual became available with all but the 5.3 engine..
The suspension system used independent front suspension with coil springs and live rear axle also using coil springs – initially at least – although some later cars replaced the rear leaf springs with air Suspension units.. Dunlop disc brakes were used on all wheels..
Production ceased in 1968, following poor sales caused by its exterior design which many considered conservative and old fashioned compared to contemporary rivals such as the Rover P6 and Ford Zephyr MkIV.. A total of 24,149 cars were built during the five year production run..
