Fiat’s world premiere in Geneva 2010: New twin-cylinder engine with Multiair Technology

Fiat displays at the Geneva Motor Show 2010 (4th is until 14 March) for the first time from autumn 2010, first offered exclusively in the Fiat 500 Twin-air engine, the harbinger of a new engine series. The equipped with a turbocharged two-cylinder gasoline engine making 63 kW and will emit less than 100 grams of CO2 per kilometer.

Developed by Fiat Powertrain Technologies (FPT), twin-cylinder gasoline engine with turbocharger has the Multiair technology, in which the intake camshaft is replaced by an electrohydraulic system. Thus, a fully variable, the respective loading condition of the engine allows optimally adapted valve timing.

The twin-Series Twin-Air, which will be the medium with outputs between 48 kW and 77 kW are available, waiting with up to 30% less consumption than a comparable four-cylinder. For the future, offered in the Fiat 500 variant, which develops 63 kW engine capacity of 900 cubic centimeters, Fiat expects to CO2 emissions of 95  g/km. An even more significant reduction in emissions (minus ten percent) will be achieved by future natural gas version of this engine.

The compact design of the new-cylinder, turns out the 23 percent shorter and ten percent lighter than a comparable four-cylinder, also enables the combination of alternative propulsion technologies. Thus, according to the Italian car manufacturer, the coupling with an electric motor or a system for recovering energy during braking, compared to a four-cylinder natural space requirements represented.


  1. This blog is great. How did you come up with the idea?

  2. This is the kind of reason why I’m highly unlikely to look anywhere other than Fiat for small cars. They’ve got such a good record regarding the environment.
