Turbocharging is one of the best ways to make horsepower and torque without a negative impact on fuel economy. Our list of the most fuel-efficient turbocharged vehicles of 2012 is dominated by European manufacturers. With little surprise, the top spots go to the Volkswagen and Audi TDI turbo-diesels. The roomy Volkswagen Passat TDI leads the list at 31 city / 43 highway / 35 combined miles per gallon (MPG). You’ll find just one entry each for the American and Japanese manufacturers, with the Chevrolet Cruze ECO and Nissan Juke landing in the top ten. The spunky Fiat 500 Abarth earns a spot in the top ten, as well. On the other side of the coin, the Bugatti Veyron earns the Thirstiest Turbo of 2012 award with ratings of 8 city / 15 highway / 10 combined (not that it matters to the typical Veyron owner).
