Detroit, Michigan – Ward’s Auto has announced the winners of its 10 Best Engines list, which includes the electric propulsion systems from the Nissan Leaf and Chevrolet Volt.

Ward’s editors named the top ten winners after evaluating 38 vehicles with new or significantly improved engines for the 2011 model year.

The winners, and the vehicles they are in, are:

– 3.0-litre TFSI supercharged V6 (Audi S4)

– 3.0-litre turbocharged I6 (BMW 335i)

– 1.6-litre turbocharged I4 (Mini Cooper S)

– 3.6-litre Pentastar V6 (Dodge Avenger)

– 5.0-litre V8 (Ford Mustang GT)

– 1.4-litre I4 with 111kW drive motor (Chevrolet Volt)

– 5.0-litre Tau V8 (Hyundai Genesis)

– 80kW AC synchronous electric motor (Nissan Leaf)

– 2.0-litre I4 turbodiesel (Volkswagen Jetta TDI)

– 3.0-litre turbocharged I6 (Volvo S60)

The engines were tested during routine daily commutes by Ward’s editors, who scored each engine on power, technology, observed fuel economy, and noise, vibration and harshness.

The 2011 list marks the largest turnover in the award’s 17-year history, with only the Volkswagen and Audi engines carried over directly from the 2010 list. All others are entirely new or heavily modified from the 2010 versions.

To be eligible for the competition, an engine must be available in a regular-production, U.S.-specific model in a vehicle priced no more than US$55,000. The awards will be presented in January at a ceremony during the North American International Auto Show in Detroit.
