Black asked BRM development engineer and test driver Ken Richardson to assess the 20TS.

[8] The TR2 has a 1,991 cc (121.5 cu in) Standard wet liner inline-four engine from the Vanguard, fitted with twin H4 type SU Carburettors and tuned to increase its output to 90 bhp (67 kW).

[2][4] The body is mounted on a separate chassis with coil-sprung independent suspension at the front and a leaf-sprung live axle at the rear.

[9] Employing a production TR2 with optional streamlining equipment (Under-shield (Part #502122), Rear-wing spats, Metal cockpit cover),[10] Triumph attained a speed of 124.889 mph on the closed Jabbeke motorway in Belgium in May 1953.

The publicity derived from these accomplishments led the factory to establish a Competition Department under the leadership of Ken Richardson, supporting both works and customer cars.

[9] Between 1954 and 1955, the TR2 was campaigned in the Mille Miglia, the Ulster TT at Dundrod, the Grand Prix of Macao, Lockbourne Races (USA), the Alpine, Monte Carlo, RAC, Thousand Island (Canada), Liege-Rome-Liege, Nigeria 24-Hour, 3rd ADAG Gruenewaldfahrt, Circuit of Ireland, Soleil-Cannes, RSAC, and Tulip rallies, among others, earning numerous Outright, Team, and Class awards including the coveted Coupe des Alpes.

[11] In 1955, a Triumph works team of three TR2s modified with disc brakes, larger carburettors, and Jabbeke windscreens were entered in the 24 Hours of Le Mans.

[9] Doug Whiteford won the 1955 Moomba TT at the Albert Park Circuit in Victoria, Australia driving a Triumph TR2.

[13] Pardon created a fixed head coupé body with a glass backlite and a large transparent Perspex panel in the roof.

The increased amount of side glass, and the clear roof panel made the interior prone to becoming uncomfortably warm.

Additionally, the steering wheel is moved closer to the car's centreline, and the floor is lowered, both by 2 cm (0.8 in).
