Fiat Powertrain Technologies will unveil its next-generation engine at the 2010 Geneva Motor Show. The TWIN-AIR engine features Fiat's electro-hydraulic valve management MultiAir system combined with special fluid dynamics optimised for the best fuel efficiency. This two-cylinder turbocharged 1.2-litre 8V motor range will deliver between 48kW (65 PS) and 77kW (105 PS) and is said to release up to just 95 g/km in CO2 emissions. Maximum torque is available at very low revs per minute.

Because it is so compact in size, approximately 23% shorter and 10% lighter compared to a 4-cylinder of equal performance and displacement, extra applications being considered for it include hybrid technology or a methane fuel feed.

The first car to get the TWIN-AIR engine will be the Fiat 500.  Available in July, the TWIN-AIR 500 produces 63 kW (85 PS) consumes 15% less fuel and has 25% more performance than the 1.2-liter 8v which achieves in the combined cycle 5.1 L/100 km (55 mpg imp / 46 mpg US).  Compared to the 1.4 16-valve which achieves 6.3 L/100 km (45 mpg imp / 37 mpg US) fuel consumption drops 30%.

Look for more precise figures to be released in Geneva.
