The current-generation GX has been around for a very long time, but Lexus has an update in store for 2022. It starts with a new entry-level model called Signature and a special edition featuring a number of black accents. Drivers will appreciate the Lexus navigation system with Remote Connect on a 10.3-inch touchscreen. All GX models use the same 4.6-litre V8 engine that generates 301 horsepower and 329 pound-feet of torque.
