GDI Engine – Direct Injection
Direct injection guarantees improved engine performance because of the cooling effect of the injected fuel inside the cylinder and the fact that the fuel is injected directly into the chamber rather than passing through the intake valves. Direct fuel injection also delivers a compression ratio of 12.2:1. This is higher than that of Ferrari engines with indirect fuel injection.The exhaust system consists of two metal matrix catalysers (one per cylinder bank), one central pre-silencer and two rear silencers. The aim was to reduce back pressure whilst still respecting current noise limits. There are by-pass valves on the rear silencers and these are electro-hydraulically commanded by the engine control unit.
The gearbox has always been an important and distinctive component for Ferrari cars,transmission is dual clutch with seven gears,the dual clutch permits independent control of the odd and even gears and their pre-selection.In this way the gear change occurs in close-to-zero times and without wheel torque interruption,dual clutch transmission (DCT) increases driving comfort and performance under sporty driving conditions, with seven speeds, reverse, electro-hydraulic operation and no torque converter.
