The Ferrari 308 GTB Vetroresina was introduced in 1975 at the Paris Motor Show sporting a fiberglass body, therefore nicknamed the 308 Vetroresina (fiberglass). Before manufacture shifted to steel, just 808 vetroresina cars were produced.

From 1975 until 1985, the Italian automaker Ferrari produced the V8 mid-engined 308 GTB berlinetta and 308 GTS, two-seater sports cars. Ferrari commissioned Pininfarina to redesign the 308 in 1975, resulting in the 308 GTB Vetroresina, which would really replace the Dino 246.

Only roughly 800 of the 308 GTB Vetroresina were created during its brief two-year production run.

The Ferrari 308 GTB Vetroresina has a 2926cc naturally aspirated V8 engine, which can generate 210 ft lbs of torque at 5,000 rpm. It weighs about 1,100 kg (2,425 lbs), has a rear-wheel drive system, a limited slip differential, and a five-speed manual transmission.

It has a top speed of about 155 mph and can accelerate from 0 to 60 mph in about 6.2 seconds.

Leonardo Fioravanti designed the Ferrari 308 GTB Vetroresina. The 308 GTB was the final product, which was unveiled in 1975. The vehicle had two seats, sweeping curves, and a 512B-like appearance.

Between 1975 and 1985, Ferrari manufactured a number of iterations of the 308 GTB. The 308 replaced the Dino 246 GT and Dino 246 GTS in 1975.
