On Fuel Economy

For a rather large, performance-focused SUV, the 2014 Porsche Cayenne isn't as bad as you might expect. In fact, with either the Diesel or Hybrid options, it could be called downright responsible.

Base Cayenne V-6 models with the standard manual transmission rate at 15 mpg city and 22 mpg highway. The optional eight-speed automatic improves the score to 16/23 mpg, for a combined rating of 19 mpg.

The Cayenne Diesel gets almost 30 mpg on the highway, and most of the Cayenne lineup isn't as irresponsibly thirsty as you might think.

The Cayenne Diesel factors in at an excellent EPA-rated 19 mpg city, 29 highway Meanwhile, the Cayenne V-6 and S Hybrid (20 mpg city, 24 highway) models are quite impressive considering their stunning, quick acceleration.

With the Cayenne S you get an extra 100 horsepower, yet still rates at 16 mpg city, 22 mpg highway, and 18 mpg combined. The Turbo's massive 500 horsepower output is only marginally thirstier.

The new 2014 Porsche Cayenne Turbo S returns the same mileage as the Cayenne Turbo: 15 mpg city, 22 highway.
