Under the Hood

For 2006, the 4.7-liter V-8 produces 263 hp and 323 pounds-feet of torque. Those numbers are down slightly from the 2005 model's 270 hp and 330 pounds-feet of torque due to new SAE testing procedures. Actual power remains the same. The engine uses a five-speed-automatic transmission, and the GX can tow up to 6,500 pounds when equipped with the optional towing package.

Full-time four-wheel drive includes a center differential that splits power 50/50 between the front and rear wheels. A Low-range mode is present.
