GT6 MK II (GT6+)
Triumph realized that they needed to find an answer to the problem, if only to keep their reputation in the USA. Their response came with the 1969 model year, with the introduction of the GT6 MK2, known in the States as the GT6+. The rear suspension was significantly re-engineered using reversed lower wishbones and rotoflex driveshaft couplings, taming the handling and turning the Triumph into an MGB-beater. The Vitesse was also modified, but the Spitfire had to wait until 1970 for any improvements to be made.
There were other changes for the MK2: the front bumper was raised (in common with the Spitfire Mk.3) to conform to new crash regulations, necessitating a revised front end, and side vents were added to the front wings and rear pillars. Under the bonnet, the engine was uprated to develop 104 bhp (78 kW) with a new cylinder head, camshaft, and manifolds. Performance improved to 107 mph (172 km/h), but perhaps more noteworthy the 0 to 60 mph (97 km/h) time dropped to 10 seconds. The fuel economy was also improved to 25 mpg (11 L/100 km; 21 mpg) average. The interior was also updated with a new dashboard and better ventilation, a 2-speed heater fan and a black headlining. Overdrive remained a popular option for the manual transmission.
