CECIL Kimber and his MG marque – the initials stand for Morris Garages, where Kimber worked – gave the world not just fast, affordable and reliable sports cars, but a new formula for making them. Lotus, Porsche and the AC Cobra are just a few examples of performance legends built on the back of proven, mass-produced models.
Early MGs were giant-killers in circuit racing and speed records, but by the early 1950s their upright, “square-rigger” styling was a major sales handicap. Jaguar’s XK120 (1948) and the later Austin Healey 100/4 and Triumph TR2 (both 1953) had reset the template.
As ever, MG turned to its racing experience. In 1951, motorsport photographer and successful MG TC racer George Phillips commissioned Syd Enever, who worked in MG’s experimental department, to design a streamlined body for the 1951 Le Mans sports car race. Based on a new TD chassis and running gear, the EX172 pointed the way for MG’s future. However, development of a streamlined successor to the TD was stalled by BMC management’s preoccupation with the Austin Healey.
After a short succession of EX prototypes, in June 1955 a trio of factory-entered EX182 prototypes arrived at Le Mans. Outwardly similar to the earlier 172, a widened chassis now allowed the occupants to be positioned much lower. Beneath the bonnet sat BMC’s fresh B-series 1.5-litre four-cylinder engine, launched in the 1953 MG Magnette sedan.
The MGA, launched in September 1955, was effectively a productionised EX182. Beneath the all-new body was a well-measured recipe of new and existing parts, including steering and front suspension partly pilfered from the recently defunct Y-series sedan.
Despite some initial resistance to the suddenly modern styling, the MGA sold up a storm. The lion’s share of production went to the US, where its timing played perfectly into the post-war sports car boom.
Performance was adequate-and-a-bit – the initial output of 54kW was quickly upped to 61kW – and road-testers were impressed with the MGA’s steering and its forgiving, long-wheelbase handling and ride.
Instant popularity in racing prompted MG to produce the Twin Cam in 1958. It was exotic, fast and fragile; just 2111 were built. Its biggerbore block and (front) disc brakes were adopted by the (sohc) MGA 1600 in 1959, followed in 1961 by a refined, swansong MkII (pictured).
Some 101,081 MGA roadsters and coupes were built from 1955-62, most being the early 1.5-litre models. It had been the biggest-selling model in MG’s history, but its successor, the MGB, would outsell it almost four times over. What could possibly go wrong?
MGAs were drawn to B-movies.

MGAs were assembled in Australia from kits by BMC in Zetland, Sydney. Local content varied, but went right up to Oz-made 1622cc engines

The 1489cc pushrod B-series engine with twin SU carbs initially made 54kW @ 5500rpm (soon 61kW @ 5600). In 1958 it was joined by an alloy-head Twin Cam variant, bored to 1588cc and making 80kW @ 6700rpm.
A pushrod version went into the MGA 1600 in 1958, later enlarged to 1622cc (69kW) for the 1600 Mk2. All drove the rear wheels through a four-speed gearbox. m in e ed
MGA’s widened chassis created lower, more spacious seating for two. The original spring-spoked steering wheel (not the solid one pictured) eased road vibrations.
Full gauges, rheostat panel switch and map reading light were pleasant bonuses on the steel-faced dash. “Rubber-filled leather trim” on dash top was a safety measure”. Roadsters lacked exterior door handles; you reached under the sieve-like soft-top and pulled a cable inside the door trim.

The wide-spaced ladder chassis retained the T-series’ 2388mm wheelbase. A pressed-steel, structural body frame sat atop; the roadster and coupe bodies were in steel with aluminium doors, bonnet and boot. Front suspension was independent by coils and kingpins, rear by leaf-sprung live axle and rack-and-pinion. Twin Cam (1958) introduced disc brakes to the ‘1600’ range.
