The Ferrari 308 GTB got an open-top version in 1977 at the Frankfurt Salon. Called 308 GTS, the car remained into production until 1980 with 3219 produced, around 50% more than the concurrent 308 GTB model.

The 308 GTS joined the Ferrari model range at the 1977 Frankfurt Salon. Visually it was very similar to its 308 GTB berlinetta stable mate, apart from the black finished solid removable glass-fiber roof panel, and the satin black finished hinged opening louvre panels over the rear quarter windows. They were hinged to permit cleaning of the rear quarter glass, and the one on the left side also gave access to the fuel filler cap, and both were lockable.

The "S" in the model title stood for "Spider", although as with the Dino 246 GTS, the spider title was a degree of artistic license, as it was in fact a targa top, with a roof panel that could be stowed behind the seats for open air motoring. As on the 308 GTB, a luggage compartment was provided in the tail of the car behind the engine bay, accessed by lifting the entire engine bay cover, which revealed a zip top luggage compartment at the rear.

As with the 308 GTB berlinetta an optional deep front spoiler was available, as was the sports exhaust system, and high compression piston plus high lift camshaft package. A further option was 16" wheels fitted with Pirelli P7 low profile tyres.

Like the berlinetta version, the GTS model was powered by a 3,0 liter V8 engine in a 90 degree configuration that developed 255bhp for European market models, and 240bhp for US market examples which were fitted with power sapping emission control equipment.
