Bentley Azure

Least efficient compact
EPA City/Highway: 9/15

The Azure is the esteemed grandfather of the Bentley family, decidedly stuck in tradition yet universally admired and respected. It dates back to 1995 - before Volkswagen ownership - and commands the marque's second-highest price ($329,990) after the new Brooklands coupe.

With a colossal 645 pound-feet of torque on tap at only 1,800 rpm, the equally ancient 6.75 liter V-8 thrusts the three-ton convertible with alarming ease. It's no wonder there's a 25.3 gallon tank on board.
