2010 Porsche Panamera – Click above for high-res image gallery

As far as high-end sports cars go, the Porsche lineup is pretty fuel efficient. Light weight and six-cylinder engines usually do the trick, but those attributes don't exactly describe the new Panamera. The large, four-door Porsche comes standard with a bare minimum of 400 horsepower, and while it isn't a Biggest Loser candidate, it won't balance the scales of justice with a GT3 on the opposing dish, either.

Inside Line is reporting that the impressive size and power of the Panamera won't lead to a gas guzzler tax, citing an email from Porsche Cars North America spokesman Gary Fong that reportedly tabs fuel economy for the 4.8-liter, 400-horsepower Panamera S and 4S models at an impressive 16 mpg city and 24 mpg highway. The 500 pony Panamera Turbo will reportedly still have a respectable 15/23 rating. For comparison's sake, Maserati's rival Quattroporte GT S achieves just 12 mpg/18 highway, and it is down 66 horses on the Porsche.

Fuel economy numbers for the Panamera are surprisingly handsome, beating even some sport coupes in the $100,000+ range. Reasons for the car's remarkable fuel economy numbers include its dual clutch transmission and the inclusion of start/stop technology. The Environmental Protection Agency hasn't yet published the official fuel economy numbers for the range, so we'll just have to sit tight for now with these preliminary figures.
