The redesigned Lexus GX promises more luxury and power than the long-running model it replaces. The three-row GX shares the GA-F platform with the Lexus LX, giving it a strong foundation, and it is larger in every key dimension. It uses a 349-hp, 3.4-liter turbocharged V6 engine with a 10-speed automatic transmission and full-time four-wheel drive. EPA estimate of 17 mpg combined is not impressive. The focus is still on towing and off-road capability. A new Overtrail trim level gives the GX heightened off-road abilities, with large 33-inch tires and a rear locking differential. Interior space is said to have increased. Lexus Safety System+ 3.0 is standard on the GX, and it includes a comprehensive suite of active safety systems.
