MG MG C Roadster

About the MG MG C Roadster

The MGC was a 2912 cc, straight-6 version of the MGB sold from 1967 and produced through to August 1969 with some sales running on into 1970. The car was given the model code ADO52. It was intended as a replacement for the Austin-Healey 3000 which would have been ADO51 but in that form never got beyond the design proposal stage. The first engine to be considered was an Australian-designed six-cylinder version of the BMC B-Series but the production versions used a 7 main bearing development of the Morris Engines designed C-Series that was also to be used for the new Austin 3-litre 4-door saloon. In the twin SU carburettor form used in the MGC the engine produced 145 bhp (108 kW) at 5250 rpm.The body shell needed considerable revision around the engine bay and to the floor pan, but externally the only differences were a distinctive bonnet bulge to accommodate the relocated radiator and a teardrop for carburettor clearance. It had different brakes from the MGB, 15 inch wheels, a lower geared rack and pinion and special torsion bar suspension with telescopic dampers. Like the MGB, it was available as a coupé (GT) and roadster. An overdrive gearbox or three-speed automatic gearbox were available as options. The car was capable of 120 mph (193 km/h) and a 0–60 mph time of 10.0 seconds.
