Brief History:
The success of Guido Barbieri's 6CS/46 prompted renewed interest at the factory in sports car racing which was rivalling that of grand prix and with the prospect of the pre-war road races being run again there was a further incentive.  Ignoring the twin-cam 6 cylinder motor of the 6CM, it was decided to further develop the single-cam that had been created for the A6.  The starting point was to increase the bore to give a 2000 cc displacement and provide a new crankshaft, which had been achieved with the A6G 2000 Berlinetta, which was now put aside by Massimino in 1947 in favour of a two seater to be called the A6GCS.  The 'G' designated a crankcase of cast iron, the C for corsa or racing and the S for sports.  The frame was tubular, without welds, of the 'Mannesman' type, an independent front suspension and a return to a more orthodox rear suspension with rigid axle and longitudinal leaf springs. Fantuzzi made a body with cycle guards and a single headlight was used to conform with the international sports category regulations.  A second version, utilising an aerodynamic 'wrap-around' body, fenders connected to the body and a light-alloy engine was developed in 1948.  The A6GCS also competed against single-seater in the new Formula 2 category with great success - minus of course the road going gear and despite an overall weight disadvantage..  On occasion the engine was mounted on the 4CLT frame which in fact was done for Fangio at Agnouleme in 1950.  In 1952 two cars sold to Argentina were equipped with a dual ignition, dual overhead camshaft engine of the type used in the A6GCM single seater.
