The Triumph TR3 is a sports car produced between 1955 and 1962 by Standard-Triumph in England. The facelifted variant, popularly but unofficially known as the TR3A, entered production in 1957 and the final version, unofficially the TR3B, was produced in 1962.
The car was powered by a 1991 cc straight-4 OHV engine initially producing 95 bhp (71 kW; 96 PS), an increase of 5 hp over the TR2 thanks to the larger SU-H6 carburators fitted. This was later increased to 100 bhp at 5000 rpm[5]by the addition of a "high port" cylinder head and enlarged manifold. The four-speed manual gearbox could be supplemented by an overdrive unit on the top three ratios, electrically operated and controlled by a switch on the dash. In 1956 the front brakes were changed from drums to discs, the TR3 thus becoming the first series production car to be so fitted.
The suspension was by double A-arms, manganese bronze trunnion, coil springs and tube shocks at the front, optional anti-roll bar, and with worm and peg steering. Unlike MGs of the same period, the steering mechanism and linkage had considerable play and friction, which increased with wear.
The rear was conventional leaf springs, with solid axle and lever arm dampers, except that the (box) frame rails were slung under the axle. The wheels were 15-inches in diameter and 4.5 inches wide (increased from 4 inches after the first few TR2s), with 48-spoke wire wheels optional. Wire wheels were usually painted, either body colour or Argent (silver), but matt chrome and bright chrome were also available. The front disc or drum brakes and rear drums had no servo assistance.
The TR3's weight was significantly more than the Morgan Plus Four and the 356 Porsches, but not much more than the MGA and MGB. All except the Morgan, which shared the same engine, were substantially less powerful.
