91 MPG combined. That’s not a typo; it’s the EPA rating for the 2023 Tesla Model X Plaid with 22-inch wheels. More specifically, it’s 91 MPGe, or miles per gallon equivalent, a measure of how efficiently an electric vehicle uses energy compared to a gasoline-powered car. To understand what this number truly means, you have to understand the Model X Plaid. This isn’t a budget-conscious commuter car; it’s a performance-oriented, family-hauling rocket ship. Drivers who choose the Model X Plaid aren’t primarily driven by fuel savings. They are drawn to the thrust of its tri-motor powertrain, the spaciousness and unique Falcon Wing doors, and the cutting-edge technology synonymous with Tesla. For this buyer, 91 MPGe is a welcome bonus, not the primary reason for purchase.

City and highway performance

The EPA breaks down the Model X Plaid’s efficiency further, estimating 94 MPGe in the city and 88 MPGe on the highway. The slightly elevated city MPGe figure reflects the regenerative braking system, which recaptures energy during stop-and-go driving. This technology allows the Model X Plaid to recoup some of the energy that would otherwise be lost as heat in a conventional braking system. On the highway, where there’s less opportunity for regenerative braking, the MPGe decreases slightly, because maintaining high speeds demands more consistent power delivery from the battery.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Tesla Model X Plaid (with 22-inch wheels) at $850. This calculation is based on driving 15,000 miles per year, using a national average electricity cost. Your actual charging costs will vary depending on your local electricity rates, driving habits, and the percentage of charging done at home versus at more expensive public charging stations. If you have solar panels, your fueling costs could be virtually zero.

Real-world expectations

While the EPA ratings provide a standardized benchmark, real-world energy consumption can vary based on several factors. Aggressive driving, frequent use of “Ludicrous” mode, carrying heavy loads, and using climate control extensively can all decrease the Model X Plaid’s efficiency. Conversely, driving conservatively, preconditioning the cabin while plugged in, and minimizing unnecessary weight can help you achieve numbers closer to the EPA estimates. Many owners find the Tesla energy graph helpful to monitor their driving habits and energy consumption in real time.

How it compares

Compared to other high-performance SUVs, the Model X Plaid is in a league of its own when it comes to efficiency. A BMW X5 M, for example, manages only 15 MPG combined. A Mercedes-AMG GLE 63 S Coupe isn’t much better at 17 MPG combined. Even hybrid SUVs like the Lexus RX 450h (30 MPG combined) and Lincoln Aviator Grand Touring (56 MPGe combined) can’t approach the Model X Plaid’s efficiency. The Audi e-tron, an EV, offers a combined MPGe of 78. While not a direct competitor, the Rivian R1S achieves a combined MPGe of 73. The Model X Plaid driver is paying for both performance and class-leading efficiency. For all Tesla fuel economy data, check out our brand hub.

Tips to maximize efficiency

Take advantage of regenerative braking. Select the “Standard” setting for maximum regeneration when you lift off the accelerator. This allows the vehicle to slow down more aggressively and recapture more energy, reducing your reliance on the friction brakes and increasing efficiency.

Precondition the battery and cabin. Use the Tesla app to preheat or precool the cabin while the vehicle is plugged in. This reduces the energy demand on the battery once you start driving, especially in extreme temperatures. Preconditioning the battery improves range and performance in cold weather, while preconditioning the cabin allows the climate control system to efficiently reach your ideal temperature.

Avoid aggressive acceleration. While the Plaid’s instant torque is intoxicating, resist the urge to floor it at every opportunity. Smooth, gradual acceleration is far more energy-efficient than repeatedly engaging “Ludicrous” mode. The Model X may be incredibly fun to drive, but it’s worth resisting the urge to fully unleash the car’s power.

Maintain proper tire pressure. Ensure your tires are inflated to the recommended pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, which reduces efficiency. Regularly check your tire pressure, especially during temperature changes. This small step is a fairly simple way to conserve energy.

Use the Tesla Trip Planner strategically. The built-in navigation system is essential for planning road trips. It can optimize your route to include Supercharger stops and estimate your arrival time while taking into account real-time traffic, elevation changes, weather, and your driving style. Proper trip planning is especially important given that factors like speed and temperature can heavily affect mileage. Compare the ratings above to MODEL MPG across all years for a more holistic view.
