21 MPG combined is a figure that, for many vehicles, would raise an eyebrow in 2025. For the Range Rover Sport P460 PHEV, it’s a nuanced story. This is a remarkable achievement for a vehicle of its stature and capability, yet simultaneously an acknowledgment that the Sport’s primary mission extends far beyond economical fuel consumption. This is not a commuter car disguised as an SUV; it’s a capable, luxuriously appointed machine designed for individuals who demand performance, prestige, and often, the ability to venture far beyond paved roads. The P460 PHEV powertrain bridges the gap between traditional combustion power and electrification, offering a genuinely luxurious experience with a surprising dash of efficiency when driven judiciously, especially over shorter distances.

City and highway performance

Looking closer into the EPA ratings, the 2025 Land Rover Range Rover Sport P460 PHEV presents 21 MPG in city driving and 22 MPG on the highway. At first glance, these numbers seem counterintuitive for a PHEV. The expectation with plug-in hybrids is often significantly higher city MPG due to their electric-only range and regenerative braking capabilities. However, this Range Rover Sport, despite its advanced 3.0L 6-cylinder engine paired with an automatic (S8) transmission, is a substantial vehicle. Its opulent cabin, all-wheel-drive system, and strong chassis all contribute to a curb weight that demands considerable energy to move. The 21 MPG city figure reflects this inherent mass, even with the electric motor assisting. On the highway, where sustained speeds dominate and regenerative braking opportunities diminish, the larger internal combustion engine does most of the heavy lifting. The slight bump to 22 MPG highway indicates the effectiveness of the drivetrain at cruising speeds, but it’s still fundamentally a powerful six-cylinder engine motivating a luxurious, all-terrain capable vehicle rather than an economy specialist. The buyers of this vehicle prioritize effortless power delivery over microscopic fuel bills, and the P460 delivers a smooth, potent driving experience.

Annual fuel cost

The EPA’s estimated annual fuel cost for the 2025 Land Rover Range Rover Sport P460 PHEV 3.0L 6-cyl stands at $2,750. This figure is calculated based on an assumption of 15,000 miles driven annually, split between city and highway, and using national average fuel prices. It’s a useful benchmark, providing a standardized look at what owners might expect to spend on fuel over a year if they primarily rely on the gasoline engine. It’s crucial to understand that for a PHEV, this $2,750 cost largely represents what you’d pay if you rarely, if ever, plugged in the vehicle to charge its battery. The true advantage, and potential for significantly lower operating costs, comes from maximizing electric-only driving. For an owner with a short daily commute and regular access to charging, whether at home or work, a substantial portion of those 15,000 miles could be covered on electricity, drastically reducing the actual fuel expenditure. However, even if an owner drives extensively without charging, the $2,750 cost is perfectly acceptable for the demographic purchasing a vehicle of this caliber. It’s a small fraction of the overall ownership cost for a Range Rover Sport, with depreciation, insurance, and maintenance representing far larger financial considerations.

Real-world expectations

In the real world, the 2025 Range Rover Sport P460 PHEV’s 21 MPG combined rating often serves as a baseline, not a fixed outcome. Owners who consistently plug in and use the electric range for shorter trips can easily see significantly “better” fuel economy readings, sometimes far exceeding the EPA’s combined figure. For example, if a daily commute is within the electric-only range (which has not been officially released for the P460 but typically sits around 40-50 miles for modern Range Rover PHEVs), an owner might go weeks without visiting a gas station. Conversely, extended road trips, particularly at higher speeds and without opportunities to recharge, will see the fuel economy figures gravitate closer to, or even slightly below, the 21/22 MPG ratings as the strong 3.0L inline-six works harder. The benefit of this powertrain lies in its flexibility. It offers the silent, emissions-free experience of electric driving for daily errands, then transitions to powerful gasoline propulsion for longer journeys where charging isn’t feasible. The buyer of the P460 wants the option of electric driving, the lower fuel costs that come with it, and the sheer power of the engine when called upon. They accept that peak efficiency demands conscious plugging in, but they’re not necessarily buying the vehicle primarily for its fuel economy.

How it compares

Comparing the P460 PHEV’s 21 MPG combined to its immediate competitors puts its performance into sharper relief. A direct internal combustion rival, like the Range Rover Sport P400 with its mild-hybrid 3.0L engine, achieves around 22 MPG combined, highlighting the PHEV’s similar gasoline efficiency once the battery is depleted. Looking at other luxury PHEV SUVs, the BMW X5 xDrive50e offers a combined 39 MPG (when considering its total electric range and gasoline efficiency), which is notably higher than the P460’s gasoline-only combined figure, but it offers a different driving experience altogether. The Porsche Cayenne S E-Hybrid, with its focused performance, typically posts around 21 MPG combined on gasoline once its electric range is exhausted, positioning it very similarly to the Land Rover. Even more traditional gasoline-only luxury SUVs like the Mercedes-Benz GLE 450 achieve around 22 MPG combined. What this tells us is that while the P460 PHEV provides the option for significant electric-only driving, its gasoline efficiency alone is competitive within the segment of large, powerful luxury SUVs. The buyer isn’t cross-shopping a pure EV or a hyper-efficient compact SUV, they are evaluating the P460 against other high-end options that offer a blend of performance, luxury, and varying degrees of electrification. For them, the ability to select the 460-horsepower PHEV, with its potent acceleration and electric range, justifies its price and fuel economy over a purely gasoline-powered variant or even a slightly more efficient competitor that might compromise on capability or luxury.

Tips to maximize efficiency

To truly unlock the P460 PHEV’s efficiency potential, consistent charging is critical. Treat it like a part-time electric vehicle; plug it in whenever possible, whether overnight at home or during the day at work. This ensures you always start with a full battery, maximizing your electric-only range for daily commuting and errands.

Use the vehicle’s driving modes judiciously. The “EV” mode prioritizes electric propulsion, while “Hybrid” intelligently blends electric and gasoline power for optimal efficiency. On longer trips, “Save” mode can maintain battery charge for later use in urban areas, or even recharge the battery using the gasoline engine, albeit less efficiently.

Smooth driving inputs are key. Aggressive acceleration and braking consume more energy, regardless of whether you’re on electric or gasoline power. Gentle throttle application and planning stops ahead of time allow the regenerative braking system to recover more energy, replenishing the battery.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, which can have a noticeable impact on both electric range and gasoline fuel economy. Make it a habit to check them regularly, especially as temperatures fluctuate.

Shed unnecessary weight. While not always practical for a luxury SUV, removing any unused cargo from the vehicle can incrementally improve efficiency. Every pound the engine or electric motor has to move requires energy, so a lighter load is an easier load.
