The GX is kind of an odd vehicle in the Lexus lineup. Essentially based on the Toyota 4Runner, this three-row midsize luxury SUV has what it takes to tackle challenging trails with confidence. Under the hood—and behind that polarizing front grille—is an indestructible 4.6-litre V8 engine that provides 301 horsepower, although fuel economy is pretty disappointing. Comfort is superb and the interior offers generous space.
