Fiat MultiAir Turbo 1.4L Wins Best New Engine of 2010 Award

Fiat MultiAir

In brief: The judging panel for the International Engine of the Year Awards has selected the 1.4L MultiAir Turbo from Fiat as the Best New Engine of 2010.

The word

The MultiAir employs an interesting electrohydraulic system which independently controls each cylinder's inlet air charge. There are five main modes of inlet valve timing and lift and the MultiAir enables infinitely variable control for individual valves as conditions require.

The system allows for increased power and torque while also lowering fuel consumption and emissions through higher efficiency. Fiat says that, compared to a traditional gasoline engine of the same displacement, the MultiAir gives up to 10% more power and 15% more torque while improving fuel economy by up to 10% and reducing emissions by 10% (CO2), 40% (particulate matter, PM), and 60% (NOx).

Fiat will begin using the MultiAir in several vehicles and will use the technology in other engine families within its lineup, including an upcoming 2-cylinder turbo.

And so ...

Toyota won the Green Engine of the Year Award for the Prius' 1.8L Atkinson-cycle engine.
