16 MPG combined, that’s the figure for the 2024 Land Rover Defender 110 powered by the supercharged 5.0-liter V8. Let’s be clear: Nobody considering this specific Defender is prioritizing fuel efficiency. They want the aural drama, the effortless power, and the sheer presence that only a strong eight-cylinder engine can deliver, all wrapped in arguably the most stylish and capable off-road vehicle on the market. The fuel bill is simply the price of admission.

City and highway performance

The EPA estimates offer a glimpse into the Defender’s thirst. City driving, where stop-and-go traffic and frequent idling are the norm, yields a dismal 14 MPG. On the open highway, that figure creeps up to 19 MPG, still far from stellar but reflective of the engine’s ability to cruise at lower RPMs. A 5.0-liter V8 is never going to be frugal, and the Defender’s considerable weight and permanent four-wheel-drive system contribute to the less than impressive numbers. The eight-speed automatic transmission does its best to keep the engine in its sweet spot, but ultimately, physics prevail.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Land Rover Defender 110 5.0L V8 is $3,600. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. It’s crucial to understand that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium is recommended), and fluctuations in gasoline prices. Aggressive driving, frequent off-roading, and extended idling will certainly push that annual cost even higher.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can vary significantly. Owners report figures both above and below the official numbers, influenced by factors like driving style, terrain, and even tire pressure. If you regularly use launch control and enjoy the V8’s soundtrack, expect to be closer to 12-13 MPG in mixed driving. Conversely, careful highway driving, with an emphasis on maintaining a steady speed, could nudge you closer to the 20 MPG mark. The Defender’s onboard computer provides real-time and average fuel economy data, which can be a useful tool for monitoring your consumption.

How it compares

Competitors in this rarefied space offer a range of fuel economy figures. The Mercedes-Benz G550, another boxy off-roader with a powerful V8, delivers similar EPA ratings around 16 MPG combined. The V8-powered BMW X5 M also lands in the same ballpark. For those willing to sacrifice some off-road capability and V8 theatrics, the six-cylinder Land Rover Defender variants offer significantly better fuel economy, achieving around 19-20 MPG combined. If a more fuel-conscious Land Rover if of interest, you can review all Land fuel economy data. Ultimately, for the Defender 110 V8 buyer, the fuel economy trade-off is deemed worthwhile for the performance and character they desire. Buyers may also be interested in ROVER MPG across all years.

Tips to maximize efficiency

While the 5.0-liter V8 Defender will never be confused with a Prius, there are still ways to mitigate its fuel consumption. Start by ensuring your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications.

Avoid aggressive driving habits. Rapid acceleration and hard braking waste fuel unnecessarily. Anticipate traffic flow, maintain a steady speed, and allow for gradual deceleration whenever possible. The supercharged V8 delivers ample torque, so even gentle throttle inputs can provide sufficient acceleration.

Minimize idling time. Modern engines are designed to be more efficient when turned off than when idling. If you anticipate being stationary for more than a minute or two, switch off the engine. This is particularly important in city environments with frequent stop lights and traffic congestion.

Consider using the vehicle’s drive modes intelligently. While the “Dynamic” mode sharpens throttle response and maximizes performance, it also increases fuel consumption. Opt for the “Comfort” or “Eco” mode for everyday driving to prioritize fuel efficiency without sacrificing too much performance.
