The Lexus GX 470 is positioned between the automaker's car-based RX 330 and the premium-luxury LX 470. Equipped with full-time four-wheel drive, the GX 470 promises the luxury appointments and workmanship of a Lexus sedan.

Roll-sensing side curtain-type airbags became available during 2004, and a rear backup camera was offered with the optional navigation system. A Kinetic Dynamic Suspension System also became available. With KDSS, hydraulic control acts upon the stabilizer bars to reduce roll stiffness in response to changing conditions.

For 2005, the GX 470 added a new Sport Package that incorporated KDSS, smoked front and rear lenses, a dark graphite finish on the 17-inch alloy wheels and black bird's-eye maple wood trim inside. That same year, all optional navigation systems added Bluetooth wireless capability.

The V-8 engine gained variable valve timing for 2005, bumping it up 35 horsepower to 270. The 2006 GX 470 remains largely unchanged, with new exterior colors and some interior refinements. Power ratings have dropped slightly due to new testing standards by the Society of Automotive Engineers, though performance is the same.
