The 308 GTB/GTS Quattrovalvole, with a removable targa roof, was presented at the 1982 Paris Salon and succeeded the 308 GTBi/GTSi. Its sweeping curves and aggressive lines designed by Leonardo Fioravanti has made the 308 one of the most recognizable and iconic cars produced by Ferrari.
The Quattrovalvole part of the model name referred to the four valves per cylinder heads on the engine, which provided increased power over the preceding model. Visually the new model was very similar to the outgoing one, but could be recognized by the addition of a slim louver panel in the front lid to aid radiator exhaust air exit, paired electrically operated door mirrors with a small enamel Ferrari badge on the shell.
The engine was capable of producing 255 bhp from its 3 liter, V8 carbureted engine. In 1980, a Bosch K-Jetronic fuel injection was installed due to new emission regulations.
Today the Rosso Corsa and the prancing stallion are known around the world. They ooze luxury, power, and wealth - but it wasn't always so. Ferrari's storied racing heritage dates to 1929 when Enzo Ferrari founded Scuderia Ferrari - 'Ferrari Stable' - to build race cars and sponsor drivers. After the war Enzo began building road cars but only as a concession to fund his beloved and expensive racing program.
The iconic Cavallino Rampante, or prancing horse, originated when he encountered an Italian Countess, the mother of a World War I flying ace. The pilot was known for painting horses on his plane's fuselage. The Countess suggested perhaps the horse might bring good luck on Ferrari's race cars. She may have been right - as decades of podium finishes on all manner of race tracks can attest.
The mid-engine, Pininfarina-designed 2.9L V8 308 GTS debuted in 1975 as successor to the Dino 246 GT/GTS. The tube-framed GTB/GTS and GT4 were mechanically similar; 5-speeds and an independent suspension with four wheel disc brakes. In 1980 the 308 GTSi was introduced. The big difference between the 'i' and its earlier Weber-carbed kin was a switch to Bosch fuel injection.
The current owner purchased this car in 1989 with just over 2,000 miles. Today it is authenticated as all-original and has under 12,000 miles on the clock.
For the initial 18 months of the 308 GTB's production, fiberglass was predominately used for the bodies, but later switched to all-metal. The fiberglass bodies were around 125 kg lighter.
The 308 was capable of producing 255 bhp from its 3 liter, V8, carburetor engine. In 1980, a Bosch K-Jetronic fuel injection system was installed due to new emission regulations. This caused the horsepower to drop to around 215 hp, thus making the 308 GTBi the slowest of the 308 series.
In 1981, Ferrari introduced 4 valve heads for the 3 liter V8's. This 308's now became known as 308 GTB/GTS Quattrovalvole. The engine now produced 240 BHP, and with the extra weight that was imposed due to using all-metal rather than fiberglass, the performance and handling was back to where it was when it began production.

The 308 was Ferrari's first two-seat V8 road car. Made available to the public in 1975, it was the long awaited successor to the incomparable Dino 246 GT. The 308 series was a new beginning for the company as the premier builder of exotic sports cars for road use. As such, the 308 was designed to epitomize the sports car in its era. It did so admirably, and remains perhaps the most influential enthusiast car in history. The 308 is the car against which every subsequent sports car has been measured, upon which every Ferrari V8 sports and racing car has been based, and the car that brought Ferrari from the pinnacle of elite car-culture recognition into the minds of the general public. 25 years later, the shape and sound of the 308 is still 'Ferrari' in the minds of many people.
Design The Ferrari 308 GTS provided Pininfarina wîth an opportunity to flex its design and styling muscle. The company responded by redefining the public's collective impression of what a Ferrari, and indeed what a sportscar, should look like. The task given Pininfarina was the creation of a two-seat mid-engined V8, and few can have expected the Turin designer to respond wîth such a tour de force.
The 308's shape bears a passing resemblance to Pininfarina's Dino 246 GT. Where the older car was the ultimate expression of curvaceous 1960's styling, the 308 hinted far more at the future. From its sharp nose incorporating a slim bumper and a deep air dam, to its retractable headlights and row of black louvres that vent air from the radiator, the line flows up the windshield and out around the flanks to reunite
with itself at the buttress C-pillars, ending in a very subtle rear lip spoiler. The design is so beautiful and effective that it has been a basis for exterior styling of every subsequent V8 Ferrari and an object of study for design students the world over.
GTS models had louvered panels over the whole of their rear quarter windows. Increased venting front and rear served to improve cooling wîth each evolution of the engine. By and large, however, the design of the 308 was so iconic and effective that it was virtually unchanged throughout its decade of production.
The heart of the 308 series was its three litre V8 engine. The 2926cc Ferrari V8 was something of a departure for the company, which had mostly relied on V12s. With the V8, Ferrari could offer much of the power of their legendary V12s while improving fuel economy and saving space. By placing the engine and transmission transversely Ferrari was able to reduce the length of their new sports cars and concentrate the mass within the wheelbase, a lesson of racing.
The transmission in the 308 was a five speed wîth reverse all synchromesh unit. Mounted transversely like the engine, the transmission received power through an unassisted single plate clutch. The gears sent power to the rear wheels through a limited slip differential and solid driveshafts wîth constant velocity joints.Source - Ferrari
