16 MPG combined is what you’ll get with the V8-powered Land Rover Defender 110. Nobody considering this specific version of Land Rover’s iconic off-roader is primarily focused on fuel efficiency. They want the sound, the power, and the drama of a supercharged five-liter V8 inside the Defender’s strong frame. They accept the fuel consumption as part of the experience.

City and highway performance

The EPA estimates of 14 MPG city and 19 MPG highway match the reality of driving a heavy, boxy vehicle with a thirsty engine. Stop-and-go traffic makes the Defender even less efficient. Highway driving is a little better, but still suffers because of the vehicle’s shape. The eight-speed automatic transmission is generally smooth and responsive, but can only do so much to reduce fuel consumption at higher speeds. The Defender’s weight also increases fuel consumption, requiring more energy to accelerate and maintain speed. More information on all Land fuel economy data can be found on our site.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,600 for the 2023 Land Rover Defender 110 5.0L 8-cyl. This is based on 15,000 miles of driving per year, using national average fuel prices. Individual spending will vary based on driving habits, local fuel costs, and city versus highway driving. However, $3,600 is a reminder of the ongoing cost of a V8-powered Defender. It rivals the down payment on a more economical car. Owners should include this cost in their budget along with insurance, maintenance, and other expenses.

Real-world expectations

The EPA estimates provide a baseline, but real-world fuel economy for the Defender 110 V8 is often lower, especially if you drive it hard. Aggressive acceleration, off-road driving, and idling will all hurt fuel consumption. Owners who tow or carry heavy loads should expect a significant decrease in MPG. Careful driving, gentle acceleration, and highway miles can help get the numbers closer to the EPA estimates, but requires effort. Few owners will do this, as they are likely enjoying all 518 horsepower.

How it compares

The Defender 110 V8’s fuel economy is very different from its competitors. The Lexus GX 460 has similar off-road capability, but only gets 16 MPG combined, showing the inefficiency of body-on-frame SUVs. The V6-powered Jeep Grand Cherokee gets 19 MPG combined, which is a good improvement and attracts a different buyer. Even within the Land Rover family, the Defender 110 with the P300 four-cylinder engine gets a better 20 MPG combined. These other engines offer similar capability in most driving, but are less appealing to those wanting a V8. ROVER MPG across all years can be found here. Owners must balance fuel economy with the engine and other features they want.

Tips to maximize efficiency

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Maintaining the recommended tire pressure, found on the sticker inside the driver’s side door, can improve MPG.

Avoid aggressive acceleration and braking. The Defender 110 V8’s supercharger is tempting, but flooring it consumes a lot of fuel. Smooth acceleration and anticipating traffic can cut fuel waste. Try coasting and avoid braking to keep your speed.

Minimize idling. Letting the engine idle consumes fuel without going anywhere. If you’re waiting or stopped for more than a minute, turn off the engine. Modern vehicles restart quickly, making this an easy way to save fuel.

Consider a less aggressive tire for on-road driving. The Defender often has tires for off-road grip, which can increase rolling resistance and hurt fuel economy on pavement. If you mostly drive on the road, a tire with a less aggressive tread can improve MPG.
