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.

Larger than the compact MKC, the MKX concept wears many of its smaller sibling's styling cues -- from the new split Lincoln grille to the lightly sculpted beltline to the upturned full-width taillights.

Fiat 500: With styling that makes it look like the spawn of a Volkswagen Beetle and a BMW Mini Cooper, the 500 does an Italian job on both competitors: It's cuter than a Beetle, and likely less expensive than a comparable Mini.
