Introduced in 1946 following the cessation of hostilities, the Triumph Roadster - produced by the Standard Motor Company - was initially available in 1.8-litre guise (18TR) between ’46 and ’48, and latterly as a 2.0-litre model, internally referred to as the TRA, and known to enthusiasts as the 20TR.
Designed in the closing years of the Second World War, the Roadster was intended to take on the likes of Jaguar, with the sculpted, largely aluminium body penned by Frank Callaby, and assembled on the chassis over an Ash wood frame.
Interestingly, the body panels were formed using ex-RAF press tools, which had previously been employed to build the De Havilland Mosquito fighter-bomber during the war.
Allegedly, the Roadster was able to seat five - three across the bench seat and two in the rear ‘dickey seat’ though even with a column-mounted shifter, seating three up front was a tricky affair, whilst the two passengers in the rear were afforded little protection from the elements, other than a fold-up windscreen.
In 1948, the 2.0-litre TRA was introduced, utilising a 2088cc Vanguard engine, transmission and rear axle, and employing a three-speed (rather than the earlier four-speed) all-synchromesh transmission, though little in the way of visible changes occurred, thanks to the easily exchangeable nature of the Vanguard parts.
In total, only 2,000 2.0-litre examples were produced - largely hand-built - and production ceased in October 1949.
