The GX 470 is Lexus' third SUV and is bracketed in size and price by the entry-level RX 330 and premium LX 470. Thanks to its luxurious cabin and excellent road manners, this is a fine luxury SUV and certainly one of the best available. As with most Lexus vehicles, the GX 470 shares a platform with a Toyota product. In this case, the cousin happens to be the 4Runner. That Lexus chose the 4Runner to base its GX on is your first clue about this vehicle's intended mission. This is a traditional body-on-frame truck design, not a car-based unibody, thereby implying that the Lexus GX 470 can be quite accommodating in its ventures off the beaten path. The implication is backed up by a full-time four-wheel-drive system, generous suspension travel and a host of electronic aids. Luxury accoutrements haven't been forgotten, however. Standard features include leather seating, genuine bird's eye maple wood trim, power-heated front seats, automatic climate control, a moonroof, rain-sensing wipers, one-touch up-down side windows and a power tilt-and-telescope steering wheel with integrated audio and cruise control buttons. The standard audio system has an in-dash six-disc CD changer and 11 speakers. It is hard to find fault with the Lexus GX 470. The only available engine is a 4.7-liter V8 that makes 263 horsepower and 323 pound-feet of torque. It's connected to a five-speed automatic that applies continuous power to all four wheels. Should a tire start to slip, the GX 470 automatically redirects torque to the wheels with the most grip. A number of features, such as a two-speed transfer case and a hill descent feature, ensure that the Lexus GX can take on off-road trails without much difficulty. Properly equipped, the GX can tow up to 6,500 pounds. The Lexus GX 470 comes standard with four-wheel antilock disc brakes with BrakeAssist and Electronic Brakeforce Distribution (EBD). It also has traction control, a stability control system and a tire-pressure monitoring system. Front side-impact and front and rear head curtain airbags are standard.
