This post is a follow up to a previous post about the Triumph TR2. The Triumph TR3 replaced the Triumph TR2 in October 1955. The Triumph TR3 was not a drastic change from the TR2. The same 4-cylinder 1,991cc engine was used; however, the engine power was increased from 90 horsepower to 95 horsepower by enlarging the inlet ports and the use of larger 1 3/4 inch SU carburetors.
On the outside, an matrix type grill was added along with some stainless steel beading along the fender/body shell joints.

The later Triumph TR3 cars were among the first cars to be fitted with disk brakes as standard equipment. The TR3 cars built between October 1955 and September 1956 had drum brakes, while the later cars up to the end of production in September 1957 had disk brakes.
The Appearance of TR3 is similar a TR2 Except for the Grill
The performance of the TR3 was not an improvement over the TR2., in fact a case can be made that the TR3 cars were slightly slower than the TR2.
As with the Triumph TR2, the TR3 was given a distinctive hood emblem. This emblem is shown below.

The Triumph TR3 was actively rallied and raced by the Triumph factory. The picture below shows five TR3s that were awarded “Alpine Coupes” for having unpenalized runs in the 1956 Alpine Rally. The three cars on the left side of the photo are the works team cars. The car on the left (SRW 991) was driven by Tommy Wisdom, the next car (SRW 991) was driven by Paddy Hopkirk, and the third works car (SRW 410) was driven by Maurice Gatsonides.

The TR3 was produced from October 1955 to September 1957 during which a total of 13,377 cars were manufactured. This was about 50% more than the number of TR2s that were produced. About 90% of the TR3s were produced for export, so they are out there, but it is not common to see a Triumph TR3 these days.
