The 2018 Land Rover Discovery and the 2018 Mercedes GLS are two solid options for luxury large SUV buyers. Both of these SUVs are hard to fault, because they excel in every department. They both offer powerful engines, sublime handling, refined and ultra-comfortable cabins, advanced technologies, and excellent practicality. A closer look at this comparison of the 2018 Land Rover Discovery and the 2018 Mercedes-Benz GLS will help determine which of the two best suits your needs and preferences.



The 2018 Land Rover Discovery is 600 to 850 pounds lighter than the 2018 Mercedes-Benz GLS, which contributes to better acceleration, handling, and fuel economy. In addition, it is 5.9 inches shorter than the Mercedes-Benz, making it easier to maneuver in tight spaces. For this reason, it may be a better choice for commuting in the city.

Also, the Land Rover Discovery's average track is 0.8 inches wider than that of the Mercedes-Benz GLS, giving it improved handling and stability. Also, with a 0.2-inch advantage in minimum ground clearance, it can negotiate rough terrain slightly better than its rival.

Fuel Economy

According to the results of EPA tests, the 2018 Land Rover Discovery Td6 has a fuel economy rating of 21/26 mpg (city/highway), while the GLS 450 delivers only 17/22 mpg. The Land Rover's advantage in fuel efficiency is partly the result of its lower aerodynamic coefficient of drag and electronically controlled shutters on its front grille. The shutters cut off airflow and reduce drag whenever the engine needs less cooling, making the SUV more fuel efficient on the highway. The Mercedes-Benz GLS does not come with active grille shutters.

Luxury & Convenience

The Land Rover Discovery comes standard with a dual-zone air-conditioning system that enables the driver and the front passenger to select two different temperatures, so that there is no need to compromise your temperature preferences. The Mercedes-Benz GLS also offers dual-zone air-conditioning but at an additional cost. Also, the Land Rover offers optional air-conditioned seats in the first and second rows to keep you and your passengers comfortable. The Mercedes-Benz does not offer air-conditioned second row seats.

If you opt for the Land Rover Discovery HSE or HSE luxury, you will have the option to get a heads-up display, which projects speed and navigation information in your line of sight. With this feature, you can stay informed without taking your eyes off the road. Heads-up display is not available on the Mercedes-Benz GLS.


The 2018 Land Rover Discovery comes with an available cross-path warning system to make backing safer. This system can help you avoid collision by using wide-angle radar to warn you of vehicles, pedestrians, or objects that are in or about to cross your path as you are reversing your vehicle. The Mercedes-Benz GLS does not offer a cross-path warning system.

Both the 2018 Land Rover Discovery and the 2018 Mercedes-Benz GLS are versatile SUVs that can perform well in almost any driving situation. If you want to know if the Land Rover Discovery is the right choice for you, feel free to stop by for a test drive.
