19 MPG combined is the reality for owners of the 2015 Land Rover Range Rover LWB 3.0L 6-cylinder. This simply isn’t a concern for the typical buyer. We’re talking about an extended-wheelbase Range Rover, a vehicle purchased for its commanding presence, unparalleled off-road ability (however seldom used), and the sheer luxury of being chauffeured in supreme comfort. Fuel economy plays a secondary role to these attributes.

City and highway performance

The EPA estimates for the 2015 Range Rover LWB with the 3.0L supercharged V6 are 17 MPG in the city and 23 MPG on the highway. That spread reflects the engine’s demands when hauling around a vehicle of this size (well over 5,000 pounds), stop-and-go driving naturally impacts fuel consumption. The highway figure is more respectable, and suggests that longer journeys, especially at a steady cruise, will yield better numbers. The eight-speed automatic transmission helps keep the engine in its optimal rev range, aiding efficiency when you aren’t demanding instant acceleration.

Annual fuel cost

According to the EPA, the annual fuel cost for this vehicle is $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for comparison, but your individual costs will vary depending on how much you drive, where you drive, and the price of fuel in your area. It’s unlikely to deter someone already prepared to invest in a long-wheelbase Range Rover, but it’s a figure to keep in mind when budgeting for overall ownership.

Real-world expectations

Manufacturer estimates rarely align perfectly with the real world and individual driving styles exert a large impact on fuel consumption. Aggressive acceleration, frequent hard braking, and neglecting recommended maintenance will all drag down your MPG. Expect the typical Range Rover LWB owner to achieve figures somewhat below the EPA estimates, particularly if their driving is predominantly in urban environments. Conversely, consistent highway driving in “comfort” mode may yield numbers that meet or slightly exceed the 23 MPG rating.

How it compares

Looking at the 2015 Range Rover’s competitive set, the fuel economy picture doesn’t drastically improve. For example, a similarly equipped Cadillac Escalade ESV managed only 17 MPG combined from its larger 6.2-liter V8. Even the Mercedes-Benz GL450 (at the time), with its turbocharged V6, only achieved 19 MPG combined. A BMW X5 xDrive35i from that year manages around 20 MPG combined, better but hardly transformative. Ultimately, buyers in this segment recognize they are purchasing a vehicle that prioritizes space, luxury, and capability over outright efficiency, but it’s still worth reviewing all Land fuel economy data. The ROVER MPG across all years shows you other options.

Tips to maximize efficiency

The Range Rover LWB’s supercharged V6 responds well to a smooth, deliberate driving style. Avoid sudden bursts of acceleration and maintain a steady speed whenever possible. Anticipating traffic flow and allowing the vehicle to coast, rather than braking harshly, can also conserve fuel.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which eats into your fuel economy. Check your tire pressure regularly and inflate them to the recommended levels found on the door jamb.

Regular maintenance is key to optimal fuel efficiency. Make sure your engine is properly tuned, and that filters (especially air filters) are clean. A well-maintained engine runs more efficiently and delivers better fuel economy.

Consider using the Range Rover’s “Eco” mode, if equipped. ECO mode tweaks the throttle response and transmission shift points to prioritize fuel efficiency. The trade-off is a slight reduction in performance, but it can make a noticeable difference in MPG.

Avoid carrying unnecessary weight in the vehicle. Extra weight puts a strain on the engine, leading to increased fuel consumption. Remove any items you don’t need, such as sporting equipment, tools, or other heavy objects. Also, remove any roof racks or cargo boxes when not in use, as they create aerodynamic drag.
