One of the most well-respected Ferraris to ever roll out of Maranello was the Dino 246, an irony when one considers the car's position in its parent brand's model lineup. An entry level vehicle with only half the cylinders of its famous big brothers, the Dino wasn't even branded as a Ferrari—it wore no prancing horse motifs and had a yellow 'Dino' badge on its nose in place of the familiar, upright rectangle. It was drop-dead gorgeous, though, and it drove with athletic grace. It inspired a new class of mid-engined Ferrari sports cars that often out-handled their more expensive (and more expansive) siblings. When the Ferrari 308 was launched in October of 1975 to replace the Dino 246, it had to meet exceptionally high expectations.
After seeing that even a V6 engine wasn't likely to tarnish the brand's sparkling reputation, Ferrari repealed the bottom-feeder 'Dino' nameplate for the V8-powered 308. With a proper badge on its nose and a triumphant horse dancing on its tail, the 308's rich bloodline was flaunted with pride. This was, of course, only appropriate for a car that looked, sounded, and went like Italy's finest.
The 308 experienced a long production run, and during that time the car was slowly strangled by evolving emissions regulations that stunted its performance. Additionally, weight was added to the car very early in its production when the fiberglass bodies were replaced by steel units. Luckily, though, Ferrari has never been a company to sit back and watch as one of their cars suffers growing pains. The home of the Prancing Horse countered the aging 308's shrinking muscles and growing gut with a midlife crisis to rival the most lavish hair transplants and tummy tucks in the form of the revised Quattrovalvole model.
In 1982, when it was clear that the 308 was growing tired, Ferrari revitalized the car with the introduction of the 308 Quattrovalvole. Translated into English, the Quattrovalvole name means 'four valves.' The new nomenclature referred to a redesigned head featuring four valves per cylinder, a first for Ferrari. The updated mill still displaced 2,962cc, and was mounted transversely behind the cockpit. The compression ratio was increased from 8.8:1 to 9.2:1 (though U.S. versions made due with an 8.6:1 ratio).
The use of Bosh K-Jetronic fuel injection was continued. When first adopted by the 308 in late 1980, the fuel injected engines produced less power than their carbureted predecessors. The power of the old carbureted models was restored with the Quattrovalvole, though. The revised engines produced 240bhp at 7,000 rpm (230bhp at 6,800rpm for U.S. versions), and enabled 0-60 times of 6.1 seconds and top speeds of 155mph.
Two body styles were offered to Quattrovalvole customers, the 308 GTBi and the 308 GTSi. The former was a coupe, while the latter came with a removable roof panel. The 308 design was penned by Pininfarina, and the Quattrovalvole models had several styling features unique to them. New side mirrors and horizontal vents across the width of the 'hood' (front lid) were included, along with a subtly reworked front grille and bumper treatment incorporating driving lights. Beginning in 1984, body panels for the Quattrovalvoles were coated to prevent corrosion.
Ferrari produced the 308 Quattrovalvole until 1985, when the 308 model range was succeeded by the 328. The 308 models in general make exceptional 'starter' Ferraris for enthusiasts who seek to experience the thrills of exotic car ownership for the price of a new Camry. Though Quattrovalvole values are on the upper end of the 308 cost spectrum, they offer an unbeatable pedigree-to-price ratio.
