Background
The MG MGA is the car that ushered the company into the latter half of the 20th century, being worlds away from the MG TD it replaced. Lower, and therefore more stable, the MGA arose from the need to create a more streamlined racing car for a privateer racer to enter into the 1951 Le Mans 24-hour race.
This - plus the fact that three prototype MGAs were raced at Le Mans in 1955, with two of them finishing in the top 20 - means the diminutive MGA has a considerable competition pedigree.
The very earliest cars were fitted with the 1489cc engine from the MG Magnette engine. These, with just 68bhp, had sprightly performance but no better, a state of affairs that was quickly remedied with a 4bhp upgrade shortly thereafter. This small, but important, change gave the newly revitalised MGA convertible and coupe a top speed of almost 100mph, and a 0-60mph time of around 16 seconds.
Nor is the MGA about power because its independent suspension and rack and pinion steering paved the way for the introduction of the Twin-Cam in 1958, a model that had genuine sporting credentials courtesy of a high-compression DOHC engine. With 108bhp at its disposal, along with four-wheel disc brakes from Dunlop and peg-drive knock-off steel wheels from the same manufacturer, the MGA was now a serious competition weapon.
As with so many serious competition weapons, this high state of tune led to problems in everyday use, so a low-compression engine with 100bhp was introduced. However, even a 113mph top speed and a 0-60mph time of 9.1 seconds wasn’t enough to save the temperamental Twin-Cam and production ended in 1960.
The standard MGA gained a 1588cc engine with 80bhp and front-wheel disc brakes in 1959. The top speed rose to almost 100mph, and it proved to be extremely popular with more than 30,000 being built in three years.
Nineteen sixty-one saw the bore increase to 1622cc, which gave a genuine 90bhp. Slight bodywork changes were also wrought, including a recessed front grille and Morris Mini tail lamps. With a top speed of 105mph and a 0-60mph time of just under 13 seconds, more than 8,000 MKII roadsters and 521 coupes were built.
