The MGA is a sports car that was produced by MG from 1955 to 1962.

The MGA replaced the MG TF 1500 Midget and represented a complete styling break from MG's earlier sports cars. Announced on 26 September 1955[3] the car was officially launched at the Frankfurt Motor Show. A total of 101,081 units were marketed through the end of production in July 1962, the vast majority of which were exported. 5869 cars were sold on the home market, and the MGA was replaced by the MGB.


Design
The MGA design dates back to 1951, when MG designer Syd Enever created a streamlined body for George Philips' TD Le Mans car. The new bodywork traded the MG TF's articulated fenders and running board for ponton styling, with a single styled envelope fully enclosing the width and uninterrupted length of a car.

The TF featured a high driver seating position. A new chassis was designed with the side members further apart and the floor attached to the bottom rather than the top of the frame sections. A prototype was built and shown to the BMC chairman Leonard Lord. He turned down the idea of producing the new car as he had just signed a deal with Donald Healey to produce Austin-Healey cars two weeks before. Falling sales of the traditional MG models caused a change of heart, and the car, initially to be called the UA-series, was brought back. 

As it was so different from the older MG models it was called the MGA, the "first of a new line" to quote the contemporary advertising. There was also a new engine available, therefore the car did not have the originally intended XPAG unit but was fitted with the BMC B-series engine allowing a lower bonnet line. The MGA convertible had no exterior door handles, however the coupe had door handles.

It was a body-on-frame design and used the straight-4 "B series" engine from the MG Magnette saloon driving the rear wheels through a four-speed gearbox. Suspension was independent with coil springs and wishbones at the front and a rigid axle with semi-elliptic springs at the rear. Steering was by rack and pinion. The car was available with either wire-spoked or steel-disc road wheels.
