The Triumph 2000 was a mid-sized rear wheel drive automobile produced in Coventry by the Triumph Motor Company between 1963 and 1977.

Using the six cylinder engine first seen in the Standard Vanguard at the end of 1960^[3] and 4 speed manual gearbox (overdrive and 3 speed automatic were options), the monocoque body had independent suspension all round using coil springs. The servo assisted brakes were disc at the front and drums at the rear. Triumph's 2000 competed with the contemporary Rover P6 2000, which initially was offered only with a four-cylinder engine.

Many of these cars are still on the road, supported by owners clubs and specialist parts suppliers. Prices vary depending on year and model with the mk1 2.5PI estate being the most valuable. A roadworthy 2000 will cost around £7-800 with mint examples fetching upwards of £3500. A mk1 PI recently sold for £11,000. The 2000 and derivatives are also popular with modifiers due to their common parts and engines shared between other Triumph models such as the TR6, GT6, and Vitesse, this has been re-enforced by recent magazine articles showcasing modified Triumphs.

Triumph 2000 Mark I; "Barb"

The "Mark I" was built between 1963 and 1969; It came in saloon and estate forms. The estate, launched in 1965 with body shell partly built by Carbodies, was in the Mark I version the same length as the saloon. Various minor improvements were made during the period of which the most noteworthy, probably, was a significant upgrade in October 1966 to the "previously rather ineffective" ventilation, with eyeball vents added in the centre of the facia and the heater controls repositioned beneath them.^[4] A substantial facelift styled by Michelotti came in 1969, updating the car for the 1970s, and was signalled as the introduction of the Triumph 2000 Mk II.

In 1968 the 2.5 PI (petrol injection) Mark I was launched, fitted with a Lucas Automotive mechanical fuel injection system. Performance was very good, but the PI models (along with the TR6 models) gained a reputation for unreliability and poor fuel economy. In Australia these models suffered badly because of the summer heat. The electric fuel pump commonly overheated causing fuel to vaporise and render the engine inoperable until the pump cooled down. The overheating of the pump was a combination very high pressure fuel loads (over 110 psi) and a pump that was adapted from what was originally a windscreen wiper motor. As such, it did not cope well with sustained pressures in moderate to high ambient temperatures. Because of the launch late in the Mark I's life, there are relatively few PIs in the original shape.

Triumph 2000 Mark II; "Innsbruck"

In October 1969,^[2] the Mark II range was launched, aping the look of the then-upcoming Triumph Stag grand tourer. There were entry-level 2000 models, which were the most plentiful, but the remainder of the range consisted of 2500, 2500 TC and 2500 PI models. Apart from the PI (petrol injection) models, all Triumph 2000 and 2500s had twin Stromberg or SU carburettors, hence the twin carburettor configurations of these cars were designated with the prefix "TC". In June 1975 the 2500S model, with 14 inch (356 mm) wheels and anti-roll bar, was added: it replaced the 2.5PI which had quietly disappeared from the show rooms two months earlier.^[5] This marked the end of fuel injected engines for the car, but improved acceleration was claimed for the twin carburettor 2500S and its slightly less expensive 2500TC sibling.^[5] These new versions featured an extensive list of other, mostly minor, improvements, of which the most significant were probably those affecting the ride and handling: these resulted from suspension changes and the associated fitting of an 'anti-sway' bar.^[5]

The Estate in the Mark II version was 5 inches (125 mm) shorter than the MkII saloon, this is because the rear bodywork of the car was carried over unchanged from the MkI version.

The Mark II, the last big Triumph car, ceased production in 1977, supplanted by BL's corporate executive car, the Rover SD1: Six cylinder 2300 and 2600 versions of the new Rover would nonetheless be powered by engines derived from the Triumph 2000. A few Triumph 2000s were still being registered in New Zealand as late as 1979.^{[citation needed]} Sir Robert Muldoon, New Zealand's then-Prime Minister, privately owned a 2500S and had been known to drive to work in it.
