The overview
The new for 2020 GLS is a very functional three-row SUV that exudes luxury with its gorgeous interior. The standard 3.0-liter six-cylinder turbo provides plenty of smooth and effortless power. An even more powerful turbocharged V8 is available. The ride is very composed and handling is responsive for such a luxury coach. All of the seats are first-rate, and the interior can be configured for either six or seven passengers. Unlike most competitors, the third-row seat is relatively roomy. However, the infotainment system is overly distracting because many common tasks require a few steps. Using steering-wheel controls too easily ends up changing a display or audio selection. Standard safety features include forward collision warning and automatic emergency braking.

Behind the data
Latest source update: September 11, 2026
Vehicle summaries, specifications, pricing and ratings come from Consumer Reports vehicle records. Auto Guide groups these records by model and reported generation start year.
Available years are listed explicitly. Gaps do not imply that a model was discontinued. Prices are source estimates, not live offers. No first-hand road test by Auto Guide is claimed.
