Background
This is the model that changed MG’s output from tiny sporting 1930s throwbacks into sleek, desirable machines. The MGA established and defined the affordable British sports car.
More than 100,000 MGAs were sold between 1955 and 1962, all but 6000 of them overseas and most of those to America. The Jaguar XK 120 might have been first and it might have been faster, but they made just 12,000 of those. Add up every TR2, TR3 and TR3A sold over ten years and you only get to 83,000.
MG offered both a hard-top coupé and a roadster. The drop-top suffered no loss of stiffness from the lack of a steel roof because the MGA used a separate chassis underneath that swoopy body. Rack and pinion steering made it pleasure to point through the bends.
The engine – a 1500cc B-series with more urge than the old T-series XPAG unit – pushed the slippery shape to 97mph in an early road test, which was properly exciting for 1955. The engine grew to 1600cc in 1959 after the interesting but under-developed Twin-Cam was launched the year before, to a chorus of warranty claims.
The only other significant change to a fundamentally excellent design was the addition of front disc brakes when the 1600cc engine arrived. The run out models, the MGA Mk II and Mk II deluxe, gained another 40cc under the bonnet with a revised cylinder head and a taller back axle for 90bhp and better cruising ability.
How about this for a final piece of trivia? The last non-American car to enter a NASCAR race before Toyota appeared in 2007 was an MGA, back in 1963. Yee-haw!
