"TR3A"
In 1957 the TR3 was updated with various changes including a full width radiator grille and this facelifted model was commonly referred to as the Triumph "TR3A". However the cars were not badged as such and the "TR3A" name was not used officially, as is evident from contemporary sales brochures. The "TR3A" was built between 1957 and 1962.
The "TR3A" was a minor update from the TR3. The updates included the new wide front grill, exterior door handles, lockable boot handle and came with a full tool kit as standard (this was an option on the TR3). The total production run of the "TR3A" was 58,236. This makes it the third best-selling TR after the TR6 and TR7. It is estimated that only 9,500 of the original 58,000 built survive in the world today.
The Triumph TR3 was the first production car to include standard disc brakes, which were continued on the "TR3A" facelift. The car was known for its superior braking ability, making it an autocross favourite.
The "TR3A" is often seen in Vintage and Production racing today. The "TR3A", despite being almost 50 years old, is still competitive in the E-Production class of SCCA (Sports Car Club of America).
In June 1977, the American Road & Track magazine published an article titled "Driving Impressions: TR3A & TR250" in its 30th anniversary issue. It published a 0–60 mph time of 12.0 seconds, power output of 100 bhp (75 kW) at 4800 rpm, observed curb weight of 2,090 lb (950 kg) and fuel consumption of 28 miles per imperial gallon (10 L/100 km; 23 mpg).
