The 2018 Range Rover Discovery comes with a standard 3.0-liter V6 engine that works together with an eight-speed automatic transmission to deliver up to 254 horsepower at 3,750 rpm and 443 pound-feet of torque between 1,750 and 2,250 rpm. Those numbers are impressive when you consider the size of the chassis this engine is tasked with moving.

The 2018 Mercedes-Benz GLS SUV comes with a similar-sized 3.0-liter V6 engine that provides a total of 362 horsepower between 5,500 rpm and 6,000 rpm as well as 369 pound-feet of torque between 1,700 and 4,000 rpm. While the higher horsepower may seem impressive, you'll want to take a close look at the high rpm range required to reach this number. For example, 5,500 rpm isn't a running condition you're likely to encounter, so you're more likely to experience more similar power and performance between these two vehicles than the officially listed numbers indicate.

Fuel Economy

One good way to measure a vehicle's overall performance is to consider how many miles each vehicle gets per gallon of fuel. The 2018 Range Rover Discovery produces an estimated combined fuel economy of 23 mpg, which ultimately breaks down to approximately 21 mpg in the city and 26 mpg on the open highway. When you compare this fuel economy rating to the 2018 Mercedes-Benz GLS SUV and its 17 mpg on city streets and 22 mpg on highways, it becomes clearer that the Range Rover Discovery runs more efficiently under the hood.

Luxury & Convenience

In many cases, luxury vehicles are on fairly equal ground when it comes to onboard technologies, and that point is true for the two SUVs in this comparison as well. One major difference, however, may make or break one option over the other for certain buyers. Both vehicles offer everything you'd expect to find such as Bluetooth connectivity and hands-free calling, streaming media playback, and a suite of sensors that allows the vehicle to take over and prevent collisions in an emergency.

The 2018 Range Rover Discovery, however, includes a feature you would almost expect to be standard in any luxury SUV that the Mercedes-Benz GLS SUV is lacking. If you're looking for a vehicle that provides rear-seat video entertainment, the only one of these two vehicles that offers this option is the 2018 Range Rover Discovery.

At first glance, the 2018 Mercedes-Benz GLS SUV may seem like the better vehicle when you compare these two SUVs. Upon closer inspection, however, the 2018 Range Rover Discovery stands out as a better overall vehicle and is an ideal choice for people looking for a great new family SUV.
