13/35 - 1924 to 1926, 13.35hp

1,873cc 4 cylinder side valve engine with 3 speed gearbox

This is the first British car to have hydraulic brakes (all following Triumph models retained hydraulic brakes). It was a development of the 10/20 with wider track and longer wheelbase. We have only recorded one 13/35 model, suggesting that Triumph did not put the 13/35 into production. 

2 body styles were planned :

4 door saloon – £495

5 seater tourer £ Unknown

Fifteen 1926-1930

Built to the same dimensions as the 13/35, but with a larger capacity engine, the Fifteen was the last of the larger conventional cars built by Triumph before they concentrated on smaller, sportier cars. As a development from the 13/35, this was the first British production car to be fitted with 4 wheel hydraulic brakes and came with an extra warning light on the rear.

We have recorded 110 and 3 survive with their original style bodywork.

5 body styles were available :-

2/3 seat tourer – £395

4/5 seat tourer – £395

5 seat coachbuilt saloon – £495

5 seat fabric saloon – £475
