The Ferrari 308 GTB (and similar 208 and later 328) were mid-engined sports cars that made up the lower end of the company's range. The 308 replaced the 246 Dino in 1975 and was updated as the 328 in 1985. The 348 replaced the 328 five years later.

The 308 GT models are the most-common historical Ferrari model, with over 12,000 produced. Although it is a common car, and is priced at accessible levels today, the 308 and 328 GTB/GTS models are embraced by Ferrari fans and critics today. In 2004, Sports Car International named this car number five on the list of Top Sports Cars of the 1970s.

308 GTB

The Pininfarina-styled 308 GTB was introduced at the Paris Motor Show in 1975 as a supplement to the odd Bertone-shaped Dino 308 GT4 and a replacement for the 246 Dino. Unlike the plain 2+2 GT4, the GTB was a 2-seater with aggressive lines, and has been called one of the most beautiful of all Ferraris. The targa topped 308GTS was made famous on the Magnum P.I. television show.

The 308GT4 shared much with the original 206 Dino, and the 308GTB is mechanically identical to the GT4. Both sit on the same tube-frame platform, with a 92 in wheelbase, and 4-wheel double wishbone independent suspension. The V8 engine is a DOHC design, with four Weber 40DCNF carburetors. European versions produced 255 hp (190 kW) at 7,700 rpm, but American versions were down to 240 hp (178 kW) at 6,600 rpm thanks to emissions control devices.

One notable aspect of the 1975 308 GTB was its fiberglass bodywork. Although still built by Carrozzeria Scaglietti, the 308's shell was entirely made of fiberglass. This lasted through June, 1977, when the 308 was switched back to steel.

GTBi and Quattrovalvole

Bosch Digiplex fuel injection was added for the other 1981 GTBi, dropping power to 214 hp (160 kW) but decreasing emissions. Two years later, the 4-valve Quattrovalvole model pushed output back up to 240 hp (179 kW).

In 1980 Bosch K-Jetronic mechanical fuel injection was added on the 308 GTBi and GTSi; emissions decreased, at the price of a power drop to 214 PS (157 kW; 211 bhp) on European models and to 205 PS (151 kW; 202 bhp) on federalized models. The Bosch fuel injection system was coupled to a Marelli MED 803A Digiplex electronic ignition system, incorporating a coil, distributor and ignition module for each bank of cylinders.[6] Outside the car was identical to the 308 GTB/GTS, save for metric sized wheels of a slightly different design, fitted with Michelin TRX radial tyres—Michelin XWX on 16-inch wheels were optional. Inside the clock and oil temperature gauge were moved to the center console; there were also a new black steering wheel with three perforated spokes, and seats of a different pattern. 494 GTBi and 1743 GTSi were produced before the model was succeeded by the 308 Quattrovalvole in 1982.[6][7]

208 GTB

From 1980 through 1985, a low-displacement 208 GTB and 208 GTS was produced. The engine was re-bored to 68.8 mm (giving an undersquare design) for a total of 1991cc displacement. This same trick had previously been performed on the 208 GT4 2+2, resulting in the smallest V8 engine ever produced.

In 1980 Ferrari introduced a two-liter 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. It was regarded as the slowest Ferrari ever made but was surpassed by 208 GT4 Bertone by American magazine Motor Trend In 1980.

The engine was de-bored to 68.8 mm (giving it an undersquare design) for a total displacement of 1,990.64 cc (121 cu in),[10] resulting in one of the smallest V8 engines ever produced. Fed through four Weber 34 DCNF carburetors, the V8 produced 155 PS (114 kW; 153 bhp) at 6800 rpm.[11] 160 208 GTS and 140 208 GTB cars were produced in 1980 and 1981.

328 GTB

1985 saw the engine displacement bumped up to 3.2 L (3185 cc) for the 328 GTB/GTS. This version raised output to 270 hp (201 kW) and top speed to 160 mph (257 km/h). 7,400 328 Ferraris were produced by the time the model was replaced in 1989 by the new 348, bringing the total for the 308/328 generation to nearly 20,000.
