Vehicle Description
In 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,[14][15] as is
evident from contemporary sales brochures.[16] 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 with its larger tyres (5.90-15 crossply or 165HR15
Pirelli Cinturato), making it an autocross favourite. 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.[17] 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.[citation

today. Despite being over 50 years old, it is still competitive in
Sports Car Club of America (SCCA) E-production class. In June 1977,
Road & Track magazine published an article titled "Driving
Impressions: TR3A & TR250" in its 30th anniversary issue. For the
"TR3A" it reported a 0-60 mph (97 km/h) time of 12.0 seconds, power
output of 100 bhp (75 kW) at 4800 rpm, observed kerb weight of
2,090 lb (950 kg) and fuel consumption of 28 miles per imperial
gallon (10 L/100 km; 23 mpg-US).[18] TR3B (1962)
