[2] The engine output was 140 bhp (100 kW) at 5,500 rpm,[3] giving the car a top speed of over 110 mph (180 km/h) when tested at Brooklands.

[4] One of the cars was entered in the 1935 Monte Carlo Rally driven by Donald Healey but was withdrawn after being written off[6] in a collision with a railway train on a level crossing in Denmark.

[4] Some spare engines and chassis were later assembled into complete cars by a London company called High Speed Motors (HSM).

A car as described above was displayed on Stand 135 at the Olympia Motor Show in October 1934 equipped with an Armstrong Siddeley-Wilson preselective gearbox.

Triumph had been moving progressively upmarket during the 1930s, and the 1938 Dolomites were very well equipped, with winding windows in the doors, automatic chassis lubrication, a leather-bound steering wheel adjustable for rake and reach, dual hydraulic brake circuits, twin trumpet horns, and spot lamps included in the price.

Head clearance was described as moderate but it was felt there was good width and leg room for two persons in the back seat and the doorways gave "reasonable entrance".

Interior fittings included three electric lights, two-way visors, a sliding roof, three ashtrays, an instrument board with large dial clock and speedometer, a telescopic spring steering wheel, wholly automatic chassis lubrication, a jacking system and a windscreen which could be wound out to give a direct view.

[9] At the front the equipment included a stabilizing bumper, two wind horns, two fog lights, two large headlamps and small side lamps on the wings.

[9] The steering and suspension were rated as "adequate", back passengers they said "travel with comfort", top speed was found to be about 75 miles an hour.Price as tested was £348.

In 1939, less than a month after Britain declared war on Germany, and before civilian automobile availability had been withdrawn by government in either country, the Autocar magazine featured a road test of the two-litre Dolomite Roadster coupe.

[2] The experience of producing hand beaten aluminium panels made the Coventry plant where the Dolomite was built a natural candidate for aircraft production as this was ramped up.
