Why luxury cars ususally have low gas mileage?

[mathilda555]

However, many of the newer luxury cars are getting better mileage. For example, some BMWs and Audis are getting in the high 20mpg range. I know someone who has a Beamer and it gets about 28 highway (of course it needs twin turbos, direct injection and all that fun stuff to get all 28 mpgs).
