With a displacement of just 875cc Fiat’s twin-cylinder gasoline ‘TwinAir’ motor seemed an unlikely choice for the International Engine of the Year Award but the little engine that could has taken the top honours. The much coveted award is decided by a jury of 76 journalists and industry experts from 36 different countries and Fiat’s mini mill was highly praised. The Jury were sold on the TwinAir’s low emissions, high fuel economy and strong power output for its size. The TwinAir scooped four awards in total that included “Best New Engine 2011”, “Best Green Engine 2011”, “Best Sub 1-Litre Engine” and the “International Engine of the Year 2011” grand award.
Fiat’s two-cylinder champion uses turbocharging to develop 63kW of power and currently sees service in the Fiat 500 and 500C, with further applications planned. Fiat will also introduce two other versions of the motor, a naturally aspirated variant producing 48kW and a higher-performance turbocharged variant with 78kW.
This year’s awards event was held yesterday (May 18th) at the Engine Expo in Stuttgart, Germany. Other big winners included BMW with the carmaker taking out four awards. The honours included winning the “3-litre to 4-litre” category with the 4.0-litre V8 unit used in the M3, the “2.5-litre to 3-litre” division for its 3.0-litre DI Twin Turbo mill, the “1.8-litre to 2-litre” category for the 2.0-litre Twin Turbo diesel engine found in the 123d and X1, and lastly the “1.4-litre to 1.8-litre” category for the popular 1.6-litre four-cylinder turbo engine co-developed with PSA Peugeot Citroen, powering the Mini.
Second place overall in the overall competition went to Volkswagen’s 1.4-litre TSI Twincharger engine, while Audi won the “2-litre to 2.5-litre” category with its powerhouse 2.5-litre five-cylinder turbocharged engine from the TT RS and RS3.
Taking out the “Best Performance Engine” title was Ferrari’s 4.5-liter V8 engine used in the 458 Italia.
