Ferrari 308 GTB Quattrovalvole
The transition from carburettor to fuel injection and the introduction of new anti-pollution laws all had a sizeable impact on the power of the 308 GTBi compared to its predecessor, the 308 GTB. Research to remedy this situation was quickly undertaken and soon showed that four valves per cylinder offered the optimal solution. This innovation saw the engine make up its lost horsepower and the car regain position as the reference point in its category.
