Lexus says the GX can conquer trails and almost any terrain. That's because this burly three-row midsize luxury SUV uses a body-on-frame architecture and features several driver-assist technologies for slippery and sloping surfaces like available four-wheel crawl control and multi-terrain select system. On paved roads, comfort and silence highlight the ride. What’s more, the GX can easily tow up to 6500 pounds thanks to a 301-horsepower V8 engine and trailer sway control system.
