designer =The Triumph 10/20 was a
car manufactured from 1923 to 1926 by theTriumph Motor Company .This was the first Triumph
automobile and was named the 10/20 for theRoyal Automobile Club 's taxation class of 10horsepower rating and its actual output of 20brake horsepower . The design was principally by Arthur Alderson assisted by Alan Lea and Arthur Sykes who were employed byLea-Francis and Triumph paid them a royalty on every car made. It was powered by a 1,393 cc (1.4L) 4 cylinder side valve engine designed byHarry Ricardo and fitted with a single updraught Zenithcarburettor . The engine produced convert|23.5|bhp at 3000 rpm giving the car a top speed of convert|52|mi/h|km/h|abbr=on and economy of mpg (Imperial)|40. The four speed gearbox was mounted centrally and coupled to the engine by a short drive shaft.At launch it came with a 2 seat, steel panelled, open tourer with provision for a third passenger in a dickey seat not made by Triumph but bought in from the Regent Carriage Company of London. This was soon joined by a Sports model with aluminium body panels and long wings and in 1924 by a fabric covered 4 seat
Weymann saloon which featured a single door on the driver's side and two doors on the other side. It had a convert|102|in|mm|0|sing=onwheelbase which made it the largest (by convert|20|in|mm|0|sing=on) of the "light cars " of its era. It was the first British production car to be fitted with hydraulic brakes but at first on the rear wheels only. Approximately 2500 of this model and the parallel 13/35 and 15/50 models were made. The price was £430-460 which was expensive when for example, a Wolseley 10 cost £250.References
