When BMW's X5 entered the SUV fray in 2000, it hit all the targets. It was roomy, comfortable and provided a `BMW' driving experience. For 2007, the competition is now Porsche's Cayenne Turbo and Audi's Q7. Fresheningup the existing model wasn't an option. BMW had to start from scratch.

The new X5 is 7.4 inches longer, 2.3 inches wider and two inches higher, riding on a wheelbase that's 4.5 inches longer. The greater dimensions are put to good use, with more shoulder- and leg-room for front and rear occupants and a usable increase in cargo volume. The new chassis is not only 15 percent stiffer than the old model, it is reportedly stiffer than BMW's successful roll-cage-equipped racing cars from the '80s.
