Fiat’s new TwinAir engine has scooped the 2011 International Engine of the Year competition, winning the major gong for engine of the year, plus three other awards including the Best New Engine 2011, Best Green Engine 2011 and Best Engine of less than 1,000 cc. The twin cylinder 875 cc engine is currently only available in a turbocharged 85 bhp configuration in the Fiat 500 and will soon also be available in the Chrysler Ypsilon, but non-turbo 65 bhp, turbo 105 bhp and 80 bhp turbo bi-fuel versions are all due this year. The TwinAir’s most distinguishing technological feature is the electro-hydraulic valve control, and a balancing countershaft to reduce vibration. Interestingly, nine of the twelve awards went to turbocharged engines.
