The Lexus LX is a big, modern, full-size luxury SUV that hasn’t sacrificed its off-road toughness. Based on the new Toyota Land Cruiser, which is no longer offered in North America, the LX600 is powered by a 409-hp twin-turbo V-6 with a 10-speed automatic transmission and four-wheel drive. Rivals such as the BMW X7 and Cadillac Escalade offer a grander experience with a more adult-friendly third row, but the LX600 has other virtues. Instead of cold and corporate, it’s made for people who don’t mind getting sand between their toes. The LX600 is the epitome of glide, with a supple ride, adjustable air suspension, and comfy seats. But its stout body-on-frame construction and Land Cruiser DNA make it a luxury SUV that’s happy to go where the dirt is.
