When the FX was first introduced a number of years ago, it was the only performance utility vehicle on the market on the less expensive side of the Porsche Cayenne.
Later, the BMW X6 joined the party, but it costs more and offers even less space inside than the FX.
The Audi Q7 swings in the opposite direction, bringing rugged ability and family-friendly passenger space to the market, but it's arguably a much more tradtitional SUV.
It does, however, offer a TDI V-6 for extra torque and miserly fuel economy.
The Land Rover Range Rover Sport is also worth considering.
The Sport received a rather thorough redesign last year, with a new engine and fully refitted interior; it doesn't have a particularly roomy interior either, but the Land Rover's British heritage and hunkered-down boxier look stand as a polar-opposite styling alternative to the curvy, organic shapes in the FX.
And to add another possibility, the Acura ZDX takes the 'coupelike' idea a step further, with an especially low roofline and 'hidden' rear doors.
Finally, for those who want better mileage and a little more practicality, look at the brand-new 2012 Range Rover Evoque.
It's one of our favorites, especially for those who spend a lot of time in the city.
