Background
The Triumph TR6 was what passed for a British supercar, back in the day. We might’ve become accustomed to family hatchbacks that boast 350bhp and rising but the announcement Triumph were building a two-seater convertible with a 2.5-litre straight-six engine that developed 150bhp was greeted with glee in the 1960s - and more than a little incredulity.
Launched in 1968, it is a simple, straightforward car. A ladder chassis supports the pretty body, a four-speed gearbox feeds power to the rear axle, and a disc/drum set-up stops the car very effectively. Fifteen-inch wheels were fitted with the then-new Michelin XAS tyre, a pairing that endowed the TR6 with class-beating handling. A rear anti-roll bar and a limited slip differential were optional extras.
Flashes of genius surfaced with fully independent rear suspension plus overdrive on the top three gears for the early cars and the top two for the later models, both of which helped quell revs at higher speeds and made the TR6 a relaxed long-distance cruiser.
A steel hardtop insulates the two occupants from the worst of the weather but it’s so heavy taking it on and off is really a two-person job, which kind of ruins any spontaneity.
But, if you’re looking for a raucous, hard-charging convertible sportscar that’s easy to maintain you might just have found your dream car; with a 0-60mph time of just over eight seconds and a top speed of 120mph, the TR6 is fast enough for almost all of us, while the later fuel-injected engine offers a greater degree of drivability and reliability than almost anything else in its class.
It went out of production in 1976, at which point Triumph had built more than 90,000.
