It had a small six-cylinder (1271cc) engine with a single overhead cam, and hydraulic brakes. The engine was modified in 1932 to make it shorter and it was moved forwards on the chassis. For 1935 the engine grew to 1378 cc. The car could initially be ordered from Wolseley as an enclosed saloon with steel or fabric body or open two-seater. From 1931 it was available without the saloon body, and was used as the basis for a number of sporting specials. In 1932 the factory added two- and four-seat coupés to the range. For its final year of production the range was rationalised to a standard saloon and coupé.
A three-speed gearbox was fitted to the earliest cars, but this was upgraded to a four-speed in 1932 and fitted with synchromesh from 1933. A freewheel mechanism could be ordered in 1934.
The engine was also used in the MG F-type and MG L-type Magnas, and MG K-type and MG N-type Magnettes.
Two sporting versions were made called Hornet Specials. The 1932-34 version of which 2307 were made had twin carburettors and higher compression and was supplied as a chassis to various specialist coachbuilders including Swallow and Cunard. For 1935 it had a 1604 cc engine but only 148 were made.
Wolseley Hornets are still in use today, as both road cars and racing cars. The Seber Family; John, Tony, Rodney, and David Seber, are one notable group to have raced the Wolsely Hornet; having relative success at amateur level and being enthusiasts for over 35 years. John Seber has rebuilt/restored over 40 Wolseley Hornets in his lifetime, with cars being sold to countries as far as Japan.
At launch the car came with a UK retail price of £175 and could be seen as a competitively priced small saloon with unusually brisk performance; but during the 1930s it gained in overall weight and lost the well judged weight distribution that gave the early Hornets much of their market-place appeal.
