In 1955,
MG threw away its traditional sportscar mould and began
producing an all new, sleek little roadster, the MGA. The MGA
was a breath of fresh air compared to all previous post-war MG
designs, which had really been restyled pre-war designs. The new
car featured a modern, low slung open roadster body, although
this was still mounted on a separate chassis and used detachable
side screens on the front doors, as was common practice on open
MG cars.
MG enthusiasts had been given a
hint of what was to come as early as 1951 when George Phillips
drove a re-bodied TD Midget in the Le Mans 24 hour endurance
race. The car had been built for him by MG following his
successes with his own TC, which had been fitted with a
lightweight two-seat race car style body.

It was a
road-going version of the Phillips car which had been proposed
to BMC in 1952 as a replacement for the TD Midget, but which had
been turned down because of the corporation's decision to build
the Austin-Healey 100. MG had gone as far as building a full
prototype of the MGA by using TD running gear, the 1250 XPAG
engine, a re-designed chassis, and the MGA bodywork.
When
it eventually became clear that the TF Midget was a bit of a
lame duck and that it would have to be replaced, the new MG
sports car was finally given the chance it deserved. The delay
in production had one advantage in that it allowed MG to refine
the design and install the much newer 1489cc four cylinder
B-series engine and its transmission from the Magnette saloon.
Traditional MG fans were surprised by the car’s modern looks to
start with but the MGA soon found plenty of eager buyers all
around the world, particularly in the all important US market.
The MGA used the new BMC B-Series engine, in twin carb, 1489cc
format which produced excellent performance (95mph) and plenty
of scope for developing as a competition car.
The MGA
sold well in this, its original "1500" form until 1959 when it
received a more powerful 1600cc engine, bringing even more
performance.
