Overview
1962
248 SP
This 2,458 cc barchetta was fitted with a single overhead camshaft V8 engine fed by four twin-choke Weber carburettors good for around 250 bhp. The tubular space-frame featured all-round independent suspension while the bodywork was very similar to the 246 SP’s. The 268 SP version was also fitted with a V8 engine the displacement of which, with the stroke increased to 71 mm, was upped to 2,650 cc.
