3rd Place: Jaguar XKR Convertible
(EPA 15/23: Combined 19 mpg)
There's no more fabulous way of guzzling in sporty open-air style than from behind the wheel of the supercharged Jaguar XKR. Its gorgeous proportions broadcast to the world that you're one sexy beast--and the maniacal whine from its supercharger make sure the peasants all run for cover. Oh, and it masks the slurping sounds coming from the fuel tank.
2nd Place: Mercedes SL Convertible
(EPA 11/18 to 13/21: Combined 14-16 mpg)
The SL is the surprise of the bunch -- while it certainly looks rich, we wouldn't have thought it was a much of a guzzler as it is. With engines ranging in size from a 5.5-liter V-8 to a 6.0-liter V-12, we shouldn't be surprised.
Even the base SL is powerful enough to suck its tank dry at a shocking rate, but if you're looking for gross excess, it would have to be the V-12 cars (SL600 and SL65 AMG), both of which manage only 11 mpg in the city. Now that's fabulous excess.
1st Place: Bentley Azure
(EPA 9/15: Combined 12 mpg)
6.8 liters, eight cylinders, a couple of turbochargers and 6000 lb of luxury to move around? That's a recipe for conspicuous consumption, and the $330,990 Bentley delivers in spades. With the only single-digit city fuel economy here, there's no quicker way than to suck the oil wells dry.
Well, okay, the Bugatti Veyron might actually use more fuel, but since it's not a convertible, the peasants fighting for crumbs on the street won't be able to see your face as clearly.
