The biggest change from the 1300 was the retrograde step to rear-wheel drive and live rear axle (still with coil springs), in the interest of simplicity and low production costs. The interior was also cheaper, with wood confined to a dashboard consisting of a simple plank with holes drilled for the quite basic instrumentation but the interior was a cut above most other small cars at a time when black plastic was commonplace. Triumph developed a Toledo "TS" two-door in 1973. It featured a 1500 cc twin-carburettor engine, but never entered production.
