Diesel joins Porsche Panamera lineup

Porsche has put forward some eye-catching fuel-economy figures for the Panamera diesel--although we may never see the car in the United States. Set to go on sale across Europe in August, the four-door is claimed to return a combined city/highway driving fuel economy of 36.2 mpg in standard guise under European testing procedures. When fitted with optional low-rolling-resistance tires, the fuel economy climbs to 37.3 mpg on the European test--a figure that gives the Panamera diesel a theoretical range of 800 miles on its 21-gallon fuel tank.

I know, production cars are usually a letdown compared to the concept, but the A7 didn’t actually have any of those massively mad bits concept cars boast – 24″ wheels, sliding doors, glass everything – it just looked good. Somehow it seems much more lumpy now we get to see the production model.
