The system controls the amount of air going into the engine by controlling when air is allowed into the engine and how much the inlet valve opens. The system works by inserting a "tappet" between the cam shaft and the valve and the engine management system can control the amount of oil that is allowed into the "tappet" thus changing the effective opening profile of the inlet valve.
The system can also change the overlap of the inlet and exhaust valves as well as changing the amount of lift and this allows the engine to maintain a steady pressure in the inlet manifold which is used to increase the amount of torque the engine produces while maintaining the efficiency of the engine. The system is said to increase torque by 20% while reducing emissions by a similar amount.
All this technology is supposed to increase the fun factor giving better and more positive throttle response. All engines will be equipped with Start&Stop system and are Euro5 rated.
The range will have 1.7L turbocharged engine the 1750 TBi - 235 PS (173 kW; 232 hp) with an exclusive Quadrifoglio Verde configuration after the launch.
