After a thorough revamping last year, Lexus' flagship SUV, the LX 570, rejoins the battle against industry giants such as the Land Rover Range Rover, Audi Q7 and Cadillac Escalade. A weak economy may hurt the entire segment this year, but with its powerful 5.7-liter engine mated to a six-speed transmission, an advanced suspension system and a sterling reputation for quality and reliability, the LX 570 stands ready to lure those few prospective buyers still shopping the full-size luxury SUV market. Those also looking for Lexus luxury with the option to traverse heavy terrain will find a solution in the LX 570.
