Geneva Preview: Fiat Twin-Air Engine

Article by Christian Andrei, on August 26, 2010

Fiat Powertrain Technologies will introduce its next-generation engine -- the TWIN-AIR engine -- at the upcoming Geneva Motor Show. The engine features Fiat's electro-hydraulic valve management MultiAir system, which when coupled with special fluid dynamics, results to the best fuel efficiency.

This two-cylinder turbocharged 1.2-litre 8V motor range is able to deliver between 48kW (65 PS) and 77kW (105 PS).

CO2 emissions are low, at only 95 g/km in. Furthermore, maximum torque is available at very low revs per minute.

Its compact size means that it is about 23% shorter and 10% lighter compared to a 4-cylinder of equal performance and displacement.

The carmaker is considering extra applications for it to include hybrid technology or a methane fuel feed. The Fiat 500 will be the first car to get the TWIN-AIR engine.

The TWIN-AIR 500, which will be available starting July, 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). When compared to the 1.4 16-valve, which achieves 6.3 L/100 km (45 mpg imp / 37 mpg US), fuel consumption drops 30%.
