Luxury SUVs have gained widespread popularity in the United States. However, until now, Audi has not had an offering in this segment of the market, leaving a gaping hole in its model lineup. But as the saying goes: arrive late, dress well. And Audi has done just that with its sensational Q7.

While the Q7 may be Audi's first-ever sport-utility, its strength and refinement suggest that Audi has been in this game for years, if not decades. As such, the Q7 represents a fresh and beautifully rendered newcomer to the luxury SUV segment. Like other Audis, the Q7 is a paragon of driving elegance and interior refinement.

Built upon the same solid architecture shared by the Volkswagen's impressive Touareg and Porsche's high-performance Cayenne, the Q7 is even nicer to drive than its two corporate cousins, thanks to a more compliant ride and Audi's decades of experience with all-wheel-drive systems, which Audi calls Quattro, or quattro. The Q7 is also the longest of the three, and thus is the only one to offer three-row seating. Audi also has equipped the Q7 with many luxury and convenience features not found on the Touareg and Cayenne, including a few not found on any other luxury SUV.

With a base price of less than $50,000, the Q7 is priced close to others in the luxury SUV segment, which also includes the Cadillac SRX, Lexus GX 470, and Mercedes-Benz M-Class. With all-wheel drive, a choice of powerful V6 and V8 engines and arguably the classiest interior in the segment, the Q7 deserves serious consideration when shopping for a luxury SUV.
