Whilst retaining the front-wheel drive of the Triumph 1300, the body featured a restyled nose, a lengthened tail, twin headlights, horizontally mounted rear light clusters and a larger boot.

The size of the Standard SC engine was increased to 1,493 cc (91.1 cu in) with a single SU carburettor and had a power output of 61 bhp (45 kW; 62 PS).

[2] In 1972 the power output was increased to 65 bhp (48 kW; 66 PS) with an uprated carburettor and inlet manifold.

It retained the same 1493 cc engine (now with twin SU carburettors) mated to the rear wheel drive drivetrain from the recently introduced Triumph Dolomite.

The 1500TC can be identified by the "1500TC" bootlid badge and the black centres on the wheel trims, which were blue on the 1500.
