At the 2011 International Engine awards, Fiat's little 875cc TwinAir engine won three categories and took home the overall 2011 International Engine of the Year award. BMW took four categories with four different engines, while Audi, Ferrari, and Volkswagen each made good showings.
Fiat's engine ekes 85 horsepower from two cylinders using a turbocharger, and only produces 95 grams per kilometer of CO2. Fiat uses the engine in its 500 model, but U.S. versions of that car are likely to get the 1.4-liter Multiair engine.
