Frankfurt preview: 2014 Porsche Panamera Diesel

The Panamera Diesel can tow up to 5,700 pounds.

Porsche will travel to next week's Frankfurt Motor Show to unveil the diesel-powered variant of the facelifted Panamera sedan. Not sold in the United States, the Diesel-badged model represents about 15 percent of Panamera sales in Europe.

The Panamera Diesel is powered by a 3.0-liter turbocharged V6 engine that makes 300 horsepower - 50 more than the outgoing model - at 4,000 rpms and 479 lb-ft. of torque from 1,750 to 2,500 rpms. Power is sent to the rear wheels via an eight-speed automatic transmission, and Porsche's Torque Vectoring Plus system is fitted as standard.

When driven conservatively, the Panamera Diesel returns 36.7 mpg in a mixed European cycle.

The extra power helps the Panamera reach 62 mph from a stop in six seconds, almost a full second quicker than its predecessor. Top speed is limited at 161 mph and the car's towing capacity has been bumped to 5,700 pounds.

The 2014 Porsche Panamera Diesel will go on sale in Germany in January of next year with a base price of €85,300 (roughly $112,000). At the time of writing, Porsche is not planning adding the oil-burning sedan to its U.S. lineup.
