Porsche 356B Carrera GTL-Abarth


Porsche commissioned a small number of lightweight 356B racecars from Abarth, the Turin-based racing specialist.
The restyled bodywork was made from aluminium and sleeker and more aerodynamic than the standard 356. The interior was stripped out to save weight, too.
The GTL was powered by an uprated 1600 engine with double overhead cams. Three versions were offered, producing 115bhp, 128bhp and 135bhp – the power differences were mainly down to the exhaust system.
Just 21 examples were built and sold to wealthy customers.
