General description

The MGA is a sports car that was produced by MG from 1955 to 1962. Announced on 26 September 1955[3] the car was officially launched at the Frankfurt Motor Show. A total of 101,081 units were sold through the end of production in July 1962, the vast majority of which were exported. Only 5869 cars were sold on the home market, the lowest percentage of any British car.[citation needed] It was replaced by the MGB.

A high-performance Twin-Cam model was added for 1958. It used a high-compression (9.9:1 later 8.3:1) DOHC aluminium cylinder head version of the B-Series engine producing 108 hp (81 kW; 109 PS). Due to detonation problems, a 100 bhp (75 kW; 101 PS) low-compression version was introduced later.[6] Four-wheel disc brakes by Dunlop were fitted, along with Dunlop peg drive knock-off steel wheels similar to wheels used on racing Jaguars, unique to the Twin-Cam and "DeLuxe" MGA 1600 and 1600 MkII roadsters. These wheels and chassis upgrades were used on a small number of the "DeLuxe" models built after Twin-Cam production came to a halt.[7] Aside from the wheels, the only outside identifier was a "Twin-Cam" logo near the vent aside the bonnet. A careful look at the rear wheel vents would also reveal another feature unique to Twin-Cam and DeLuxe: those four-wheel Dunlop disc brakes mentioned above. 

An open car was tested by The Motor magazine in 1958 and was found to have a top speed of 113 mph (182 km/h), acceleration from 0–60 mph (97 km/h) in 9.1 seconds and a fuel consumption of 27.6 miles per imperial gallon (10.2 L/100 km; 23.0 mpg‑US) was recorded. The test car cost £1,283 including taxes of £428
