The Ferrari 308 GTB berlinetta and targa topped 308 GTS are V8 mid-engined, 2-seater sports cars manufactured by the Italian company Ferrari from 1975 to 1985. The 308 replaced the Dino 246 in 1975 and was updated as the 328 in 1985. The similar 208 GTB and GTS were equipped with a smaller 2-litre engine and sold mostly in Italy.
in 1980 Ferrari introduced a two-litre version of the 308, 208 GTB and 208 GTS. Though mainly for the domestic Italian market, where new cars with engines above 2-litres were subjected to a much higher value added tax, they were also listed in New Zealand. The 208 GTB/GTS replaced the 208 GT4 2+2.
The engine was de-bored to 68.8 mm (giving it an undersquare design) for a total displacement of 1,991 cc (121 cu in), resulting in one of the smallest V8 engines ever produced. Fed through four Weber 34 DCNF carburettors, the V8 produced 155 PS (114 kW; 153 bhp) at 6800 rpm. 160 208 GTS and 140 208 GTB cars were produced in 1980 and 1981
The Ferrari 308 GTB was launched at the Salon de l’Auto in Paris, just two years after the 308 GT4. The 308 GTB was a true Ferrari, and not as the 308 GT4 considered to be “just” a Dino.
Ferrari got the FIA group 4 homologation papers for the 308 GTB in November 1976. The following two years only a few privateers gave the 308 GTB exponation in competition.
