MG MGC GT
The MGC, produced from 1967 to 1969, was MG's attempt to create a more powerful grand touring version of the MGB by fitting a 2.9-litre six-cylinder engine. While conceived as a replacement for the Austin-Healey 3000, the MGC was critically panned on launch for its nose-heavy handling and underwhelming performance relative to expectations. However, time has been kinder to the car, and the MGC GT is now appreciated as a refined and capable long-distance touring car.
The 2,912cc inline-six engine, designated the BMC C-Series, produced 145 horsepower with twin SU carburetors. The engine was heavier than the MGB's four-cylinder, significantly affecting the car's weight distribution. The front suspension was redesigned with torsion bars replacing the MGB's coil springs to accommodate the longer engine, but the result was a nose-heavy car that lacked the MGB's agility.
The GT coupe body, with its distinctive bonnet bulge to clear the taller engine, provided genuine grand touring utility. The hatchback rear offered practical luggage space, and the fixed roof provided better weather protection and structural rigidity than the roadster. With overdrive engaged, the MGC GT could cruise at high speeds with the engine barely above idle, its long-legged gearing making it a relaxing motorway companion.
At the time of its launch, the MGC was judged against the Austin-Healey 3000 it was intended to replace, and found wanting. The Healey was more characterful, faster in a straight line, and better balanced. Journalists were disappointed, and the poor reviews severely damaged sales. Only 4,542 GTs and 4,457 roadsters were produced before the model was discontinued.
In the decades since, the MGC has been reassessed more favorably. Owners have found that modifications to the front suspension can significantly improve handling, and the smooth, torquey six-cylinder engine is genuinely pleasant for long-distance touring. The car's relative rarity — far fewer were made than the ubiquitous MGB — has added to its appeal.
The MGC GT now occupies a unique niche, offering the MGB's practicality and charm with the refinement and power of a six-cylinder engine, at prices that represent excellent value compared to other classic British GTs. It is a car that rewards sympathetic ownership and understanding of its strengths as a tourer rather than a sports car.
Rust is the major concern — check sills, floor pans, front wings, and the bonnet bulge area. The C-Series engine is robust but heavier than the B-Series four; check mounting points for stress. Torsion bar front suspension is unique to the MGC; check for wear and correct adjustment. Overdrive is essential for motorway use; check operation in all gears. Wire wheel cars are more valuable than disc wheel versions. Many MGCs have been converted to V8 or other engine specifications; original six-cylinder cars are increasingly valued.
Produced at Abingdon from 1967 to 1969 alongside the MGB. Total MGC production was approximately 9,000 units across GT and Roadster body styles. The car was intended to replace the Austin-Healey 3000 but failed commercially. The C-Series engine was shared with the Austin-Healey 3000 and Austin 3-Litre.
