At an EPA-rated 22 mpg city, 32 highway with the automatic transmission and four-cylinder, the 2011 Volkswagen CC has some pretty impressive fuel economy numbers for such a large car. However as soon as you step up to the V-6 engine (which includes 4Motion all-wheel drive), the CC gets a lackluster 17/25.
The CC four-cylinder isn't class-leading, but it's mileage is about the same as four-cylinder models of other engaging sedans such as the Mazda6 and Nissan Altima.
Next year Volkswagen will introduce a new Passat, which will be considerably greener, as most of the lineup will be powered by a TDI diesel four-cylinder allowing a highway rating of more than 40 mpg.
For such a large sedan, the Volkswagen CC is a reasonably green choice—provided you get it in four-cylinder form.
