Cars

The Triumph TR6 is one of the most popular British cars. Introduced in 1968, it is the direct successor to the TR5/250, which left a taste of too little for testers and customers alike. the restyling of Karmann, will prolong it until 1976, year of its replacement by the TR7.

The TRs are powered by an in-line 6-cylinder engine, which is completely different from the previous 4-cylinder engine. 74.7 mm bore and 95 mm stroke, i.e. 2498 cm3, and a Lucas indirect fuel injection, still relatively uncommon at the time for a power of 150 hp at 5500 rpm.

Placed in the TR4’s chassis, the unit is still relatively light and remains under 1100 kg when empty. In fact, this engine transforms the roadster into a “200 km/h” car, while at the same time gaining a lot of pleasure thanks to the smoothness and the suggestive sound of the English in-line 6.

On the transmission side, we find the usual 4-speed gearbox with its usual qualities and the classic overdrive on the last 3 gears remains an option. Acceleration is close to that of a Porsche 911 E: less than 17 seconds in the 400-meter standing start and less than 31 seconds in the 1000-meter race.

The 100 km/h is reached in just under 9 seconds. Overall performance is therefore significantly improved, albeit at the expense of fuel consumption.

This car is one of the rare versions of the 1st CC series, the 356th built: the car is of American origin and conforms to its original delivery as attested by the accompanying British Heritage. It was re-imported by an Englishman with a passion for the brand in 2009, who completely restored and improved it to make a particularly high-performance, reliable car. The restoration was the subject of articles in the English Triumph club magazine. First, the engine was completely rebuilt, the Stromberg carburetors and American low-compression cylinder head replaced by a Fast Road cylinder head and modified camshaft, SU HS6 carburetors, an aluminum manifold taken from a Triumph 2500 saloon, and a 2×3-in-1 stainless-steel exhaust with double exhaust line. In addition, an electronic ignition system has been fitted and the lower engine has been fitted with new, reinforced pistons, all balanced with the crankshaft and nitrided. The result is an engine that develops 160hp at 5500 rpm, revs up with disconcerting ease, and boasts excellent torque for this 2.5-liter 6-cylinder. More powerful and, above all, more reliable than the European engine equipped with the delicate Lucas injection system. Suspension has been upgraded with new springs and adjustable Koni shock absorbers at the front and adjustable telescopic Gaz shock absorbers at the rear. These modifications considerably improve the car’s handling and comfort. The brakes have been overhauled with the installation of aluminum shoes and higher-performance brake pads. The bodywork, of course, has not been forgotten, and has been completely redone and repainted in its original color. The vinyl hood has also been replaced by a canvas one.

All in all, a reliable car that’s particularly pleasant to drive, thanks to the engine’s liveliness and the use of overdrive in the last 3 gears.

The current owner has owned the car for 11 years and covered 33,000 km. during this period (3,000 km per year).
During this time, all maintenance work was carried out, including replacement of the clutch (2017), alternator (2016), radiator (2016), rear axle and drive shafts (2016), Hi Torque starter, Vredestein Classic tires, electric fuel pump and circuit breakers, rebuilding of steering and front axle ball joints (2022) and all conventional components.
