With so many SUVs on the market, finding the right one can be a challenge. If you're torn between the 2018 Land Rover Discovery or the Mercedes GLS 450, here's a quick comparison between these two luxury SUVs to help you decide.



The Land Rover Discovery has a choice of two engines. A 3.0-liter turbocharged diesel engine produces 254 horsepower and 443 pound-feet of torque. It has a maximum speed of 130 miles per hour. Alternatively, the 3.0-liter V-6 gasoline engine delivers 340 horsepower and reaches a top speed of 133. Both are paired with an eight-speed automatic transmission.

The Mercedes GLS 450 has a 3.0-liter twin-turbo direct injection V-6 engine that delivers 362 horsepower and 369 pound-feet of torque. It comes with a nine-speed automatic transmission. The GLS accelerates faster going from 0-60 in 6.5 seconds compared to the Discovery's 8.1 seconds with the diesel engine and 7.1 with the gasoline engine.

Fuel Economy

The GLS's fuel efficiency is slightly better at 17 mpg/city and 22 mpg/highway compared to the Discovery's 16 mpg/city and 21 mpg/highway. The GLS boosts fuel economy further with its ECO Start/Stop system that automatically shuts off the engine when the car is stopped or idling. However, if you really want to save on fuel, opt for the Discovery's diesel engine that scores 21 mpg/city and 26 mpg/highway.

Luxury and Convenience

Both vehicles are premium full-size SUVs offering spaciousness, leather seats, wood accents, rear seat entertainment, and rear tinted windows.

The Discovery features a convenient refrigerated center console to keep drinks cold. The climate control panel opens to reveal an extra compartment that can be used to keep phones or wallets out of sight.

The GLS 450 comes standard with a sunroof, a feature that is optional on the Discovery. Available on the GLS is an intuitive touchpad controller on the center console with swipe-and-pinch functionality right at your fingertips. The GLS ranks at No. 2 on U.S. News' 8 Best Luxury Large SUVs.


Safety features on both vehicles include plenty of airbags, antilock brakes, stability control, brake assist, and driver attention assist. 

The Discovery has an optional heads-up display that projects speed and navigation information in front of the driver's line of sight so that you don't have to take your eyes off the road.  

The GLS features crosswind assist, anti-whiplash head restraints, and a handy "brake hold" feature. When on a hill or a traffic light, brake hold allows you to keep the brakes applied without having your foot on the pedal. 


Both vehicles are covered by a limited warranty of four years or 50,000 miles, whichever comes first. However, the Discovery's unlimited mileage corrosion warranty is for six years - two years longer than the GLS.


The Land Rover Discovery has three trim levels priced from $52,090 - $65,490. This means you can get the top of the range Discovery HSE Luxury trim for less than the Mercedes GLS 450 that's priced at $69,550.

Both the Discovery and the GLS are an excellent choice in SUVs. Deciding which one is for you may simply come down to brand preference or price. Visit Land Rover Buckhead to find out more about both vehicles.
