Triumph GT6 Classic Cars

A Cool British Classic: The Triumph GT6

A quintessentially 'British' sports coupe, the Triumph GT6 was only in production between 1966 and 1973. The GT version of the Spitfire 4 convertible, the GT6 had a fastback design that strongly resembled the Spitfire MkII. eBay offers a selection of Triumph GT6 models for sale.

Triumph GT6 collectability

The relatively small number of these sports coupe models produced means that they are always of interest to enthusiasts. With less than 41,000 units produced - in comparison to the Spitfire convertible which had a production run of 300,000 vehicles - the Triumph GT6 is rarer and therefore maintains its cachet and status.

What are the Triumph GT6 variant differences?

In its short production run, three Triumph GT6 variants were released, known as MkI, MkII, and MkIII:

  • 1966-1968: The debut Triumph GT6 MkI had a power bulge on the bonnet and the engine offered 95 bph with 117 lbs of torque at 3000 rpm. An optional, child-sized rear seat was available.
  • 1968-1970: Also known as the GT6+, the GT6 MkII corrected previous rear suspension issues with reversed lower fishbones and Rotoflex driveshaft couplings. The dashboard was updated and a two-speed heater was added.
  • 1970-1973: The final iteration of the GT6 saw significant bodyshell changes. The MkIII was released with a smoother front end, a cut-off rear end, and recessed handles. In the final year of production, the rear suspension was a swing-spring layout and seats were covered in cloth, not vinyl.
