Triumph TR3A (1957–1962)
​
In September of 1957 the TR3 was updated, and this revised model was commonly referred to as the Triumph "TR3A". The cars were still badged as TR3s, and the "TR3A" name was not used officially, as is evident from contemporary sales brochures. Changes included a new full-width front grille, exterior door handles, and a lockable boot handle. The previously optional full tool kit became standard equipment. The "TR3A" carried over the standard front disc brakes introduced on later TR3s. The car was known for its superior braking ability, making it an autocross favorite.​

Other changes were made to the car i​n 1959, including raised stampings under the bonnet and boot hinges and under the door handles, as well as a redesigned rear floor section. In addition, the windscreen was attached with bolts rather than the Dzus fasteners used on the early "A" models. This year new options included a 2138 cc engine, and 60-spoke wire wheels.
Although the facelifted TR3 is often referred to as the TR3A, it is badged as "Triumph TR3"
​
The "TR3A" was built between 1957 and 1962. Total production was 58,236 cars, making it the third best-selling TR in its own right. The TR3A was so successful that the original panel press tooling wore out and had to be replaced. It is estimated that only 9,500 of the original 58,000 built survive today.
​
The "TR3A" is often seen in vintage and production racing today. Despite being nearly 70 years old, it is still competitive in Sports Car Club of America (SCCA) E-production class.​​​
