Engine and Transmission

With an apparent turbo lag, the SUV moves quick enough for what it offers but the busy transmission depresses the powertrain, resulting in an overworked driving experience.

The GLS alongside its younger sibling, the GLEE, is one of the most economical SUV among its rivals with the most expensive rival i.e. Lincoln Navigator. The engine used by GLS 450 is the smallest compared to the Lincoln and Cadillac, while the GLE houses the same powertrain but with a reduced output.

Lincoln with the bigger engine provides more torque and power than GLS 450 and a poised handling but they are both almost on par with their fuel efficiency. Although both have almost same exterior dimensions, Mercedes is relatively lighter than Lincoln but the American is more spacious as compared to the German heavy duty. The Navigator is a better package as compared to the German SUV and is a better car to own.

Mercedes Benz GLS 450 vs Cadillac Escalade

Albeit housing a more powerful powertrain under its hood, the Escalade is no match to the prowess and interior quality of the Mercedes. The American also houses an extensive host of standard features but is more cramped in the third row seating area. With no match to the ride quality in comparison to the Silver Arrow, the Cadillac is an SUV to be forgotten when the GLS stands beside it.

Mercedes Benz GLS 450 vs Mercedes Benz GLE 400

There's a similar pattern in both the SUVs; the major differences are the price availability of these GL-Class heavy duties. The GLS is a much larger and spacious car while the GLE is a more affordable luxurious SUV. In terms of performance and handling, both the cars are great in their respective offering. If money is no issue, the GLS is your SUV. However you won't feel like you've missed out on much if you brush aside the GLS and soup up your GLE with optional features, effectively bridging the price gap closer to its elder brother.

The 2020 Mercedes Benz GLS 450 is a quite high-priced and large and luxurious SUV. It is not that mechanically strong than its competitors but provides one of the best interior and exterior features. Having said that, the GLE 400 is a better option to the GLS where you can equip your GLE 400 or better yet, purchase the AMG GLE 43 for the similar price of the lead SUV in this review; this will give you better performance alongside a host of opulent features and superior technology.
