Description
The Ferrari 308 GTB Quattrovalvole, introduced in 1982, was the updated version of the 308 GTB, designed to restore much of the performance lost in the preceding fuel-injected models. The “Quattrovalvole” name, meaning “four valves” in Italian, referred to the new cylinder head design that featured four valves per cylinder instead of two. This significant mechanical upgrade improved airflow, combustion efficiency, and overall power output, bringing the 308 back into line with the performance expectations of a Ferrari sports car.
The mid-mounted 2,926 cc V8 retained Bosch K-Jetronic fuel injection but now produced around 240 horsepower in European specification and approximately 230 horsepower in U.S. versions, thanks to the 32-valve layout and higher compression. Power was sent to the rear wheels via a five-speed manual gearbox with Ferrari’s iconic open-gated shifter, and the car remained faithful to the 308’s established formula of a transversely mounted V8, fully independent suspension, and ventilated disc brakes at all four corners.
Stylistically, the 308 GTB Quattrovalvole looked almost identical to the earlier GTSi and GTBi models, with the same Pininfarina-penned wedge shape, pop-up headlights, and distinctive side air intakes. Subtle changes included a new black louver panel between the pop-up headlights, body-colored front and rear spoilers, and slightly different badging. European models retained the slim bumpers, while U.S. versions continued with the larger impact-absorbing units and side marker lights required by federal regulations.
The interior remained focused on the driving experience, with leather-trimmed sports seats, a compact three-spoke steering wheel, and clear, driver-oriented instrumentation. Equipment levels were modest by modern standards but appropriate for a pure sports car, and the low-slung driving position combined with excellent visibility made the GTB QV engaging both on twisty roads and long-distance journeys.
Performance was once again a strong selling point, with the European GTB Quattrovalvole capable of 0 to 100 km/h in around 6 seconds and a top speed approaching 250 km/h. Handling was sharp and well-balanced thanks to the mid-engine configuration, precise steering, and well-tuned suspension, characteristics that made the car as rewarding on a mountain pass as it was stable at high speed.
The 308 GTB Quattrovalvole remained in production until 1985, when it was replaced by the closely related Ferrari 328 GTB. Today, it is often regarded as the most refined and best-developed version of the carburetor-era-styled 308, offering improved performance and reliability while retaining the purity of the original design. For many enthusiasts, it strikes the perfect balance between classic Ferrari looks, usable power, and everyday drivability.
