Triumph TR 250 classic cars for sale

History of the Triumph TR 250

The Triumph TR 250 emerged in July 1967 as the successor to the much-loved Triumph TR4/TR4A, but it was tailored for the stricter emissions standards of the US market. Almost identical to the Europe-only TR5, the TR 250 swapped fuel injection for a pair of Zenith-Stromberg or SU carburettors to meet American regulations. Built in Coventry, its curvaceous body was penned by Italian designer Giovanni Michelotti, and distinguishing features included sculpted exhaust tips, wider side trims, a modified grille, and new badges. The TR 250 delivered British roadster dynamics packed in a body just 3.9 metres long and barely 1,060 kg, with the comfort and minimalism that marked the era.

Model history

The TR 250 is heavily based on the Triumph TR4A, continuing its chassis and suspension layout, but evolved with a 2.5-litre straight-six engine. Its predecessor, the TR4 (1961–1967), was famed for its independent rear suspension (IRS) and Italian styling. The TR 250 itself only lasted in production for about 15 months, being succeeded by the TR6 from 1968, which continued the straight-six engine tradition but with updated styling and improved handling. TR 250 production was strictly for North America, with all 8,484 examples exported, where they competed directly against homegrown convertibles and European rivals alike.

Highlights

Distinctive features of the TR 250 include the straight-six 2.5-litre engine, authentic rear-wheel drive dynamics, and unique carburettor setup distinguishing it from its TR5 sibling. Other trademarks are the robust 4-speed gearbox (usually with optional Laycock de Normanville overdrive), wood-trimmed dash, leather seats, and classic analog instruments. Externally, features like the surrey top (removable hard- and soft-roof sections), wire or Minilite alloy wheels, and chrome accents abound. Most cars arrived left-hand drive for the US, with matching commission numbers ("CD" prefix with "L" for LHD). Accessories such as full tonneau covers, period radios, and even factory air conditioning were available.

Special Editions and Collectible Models

The TR 250 itself was produced in just one standard configuration for the US market. However, originality can be found in rarities such as cars fitted with factory overdrive ('O' in commission number), factory hardtops, or rare colour schemes like Royal Blue, British Racing Green, or Signal Red. Cars with original accessories, such as the surrey top or period Blaupunkt radios, are particularly sought after by dedicated collectors.

Weak Spots and Common Issues

Typical issues for the TR 250 include minor oil leaks from the engine, a trait shared with many British cars of the 1960s. Pay close attention to the health of carburettors and the condition of the chassis for rust, especially in cars re-imported after spending decades abroad. The clutch can be heavy, and the overdrive system requires regular maintenance. The brake servo and rear drum brakes should be checked for wear. As there is no electronic assistance or airbag, the car's spartan setup means owners should inspect all mechanical and hydraulic systems regularly.

Engine and Performance, Transmission and Handling

The 2.5-litre six-cylinder provides a throaty soundtrack and a robust power curve, delivering 104–111 PS to the rear wheels. Thanks to the relatively light curb weight, the TR 250 accelerates from 0 to 100 km/h in about 10.6 seconds. The independent rear suspension, introduced with the TR4A, yields precise handling and authentic cornering feel by today's classic standards. The overdrive transmission (where fitted) allows up to seven forward gears, enhancing both performance and relaxed cruising at higher speeds. The rack-and-pinion steering is direct but unassisted, and the braking system, with front discs and rear drums, provides period-correct stopping power. Popular variants to note include TR 250s fitted with the Laycock overdrive and those sporting period correct wire wheels, as well as examples in original factory colours and configurations.

Interior, Comfort, Exterior and Design

Designed by Giovanni Michelotti, the TR 250 presents clean lines, chromed bumpers, and a distinctive grille. Interior appointments typically feature leather seats, a walnut-veneered dashboard, and large, analog gauges for all crucial functions. The seat position is deliberately low, giving a cockpit feel, and provides enough head- and legroom for even tall drivers. Classic accessories such as the surrey top (separable hard and soft sections), Persenning (full tonneau cover in mohair or canvas), and wood-rimmed steering wheels are often found. Original equipment might include Blaupunkt radios and tartan fabric details. Externally, chrome wire or Minilite wheels, badgework, and vivid paint schemes set off the British-Italian collaboration.

Other Information

The TR 250's minimal luggage space is due to a full-size spare kept in the boot. Many examples have been re-imported to Europe after originally being sold in the US, sometimes resulting in unique restoration details. With no electronics, no driver assistance, and a mechanical ignition system, this is classic driving in its purest analogue form.

Summary

The Triumph TR 250 stands out as a rare, US-market-only roadster, combining the best of British engineering and Italian design for a brief but memorable production run. Its robust six-cylinder engine, chassis dynamics, and timeless styling continue to attract enthusiasts seeking an undiluted classic roadster experience.
