There’s no need to go on and on about the fact that the Lexus GX is nothing more than a Toyota 4Runner in fancy clothes. Obviously, there are luxury features throughout the vehicle’s interior – otherwise it wouldn’t be a Lexus at all, would it? The engine, however, does not come from the 4Runner. It’s a 4.6L V8 paired with a 6-speed automatic transmission. The Ultra Premium option includes a more sophisticated AWD system.
