When it comes to fast automobiles, one needs to sacrifice certain amount of practicability to gain those extra horses under the hood. Of course, there are exceptions, especially from European automakers such as Audi and Mercedes-Benz, and Jaguar is about to enter the family-friendly sports wagons segment. The 2014 XFR-S Sportbrake is in essence a station wagon version of their XFR-S, the fastest sedan in the world. Equipped with V8 5.0-liter supercharged engine that pumps out 510 horsepower, the power is more than adequate for zooming around the car park of malls and picking up your kids. Stand still to 60mph is reached in mere 4.6 seconds, a perfect sleeper for having fun in the streets.
