The Type S : the model in the sale. This model benefitted from an evolution of the MT4 chassis. It had the same front axle but the chassis was widened to lower the centre of gravity. The real innovation was the redesigned engine. It was still a twin overhead cam 4-cylinder unit but was lighter, more compact and very powerful. The engine was built in different sizes : 750 cc, 1100 cc (the S 273 in the sale), 1500 cc and 2000 cc. In the car on offer, chassis n°1187, the engine has a cast iron block and aluminium cylinder head with two twin-bodied Weber DC03 carburettors, and magnesium oil sump. The number 273 corresponds to the unit cylinder size of the four-cylinder 1100cc engine. Producing 95 bhp, this aluminium barchetta of 480 kg was capable of 200 km/h.
There is another O.S.C.A Type S with a Tipo S 273 engine stamped n° 1137 that wears the identity of chassis 1187. We believe this to be a genuine O.S.C.A Type S chassis with the wrong identity. This barchetta was exhibited at Rétromobile in February 2001 and Pebble Beach in August 2008.
