105 MPG combined might seem like the headline for a compact hybrid, but that’s the figure achieved by the 2021 Tesla Model X Long Range Plus, a powerful, all-wheel-drive, seven-passenger SUV that can also launch from 0-60 mph in under five seconds. The Model X doesn’t apologize for its size or its mission. Instead, it delivers groundbreaking performance and unparalleled practicality, all while using electrons instead of gasoline. Its buyers prioritize innovation, technology, and a commitment to sustainability, accepting any compromises in charging infrastructure as part of the change.

City and highway performance

The Model X Long Range Plus shows impressive efficiency in both city and highway driving conditions. The EPA estimates 109 MPG in the city and 101 MPG on the highway. This difference, though relatively small, reflects the regenerative braking system’s effectiveness in stop-and-go traffic, recouping energy that would otherwise be lost as heat. On the open highway, the Model X benefits from its aerodynamic design and efficient powertrain, maintaining triple-digit MPG figures even at higher speeds. However, keep in mind that aggressive acceleration and headwinds will reduce these numbers.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Tesla Model X Long Range Plus at $700. This figure is based on driving 15,000 miles per year, using a national average cost of electricity. It’s a good comparative figure, meaning the EPA uses the same methodology for every vehicle to easily compare against gasoline counterparts. While individual electricity costs will vary based on location, time of use, and charging habits, the $700 figure provides a valuable benchmark. Home charging, particularly during off-peak hours, can even reduce this cost significantly below the EPA estimate. For its performance and size, this annual cost represents a considerable saving compared to similar gasoline-powered SUVs.

Real-world expectations

While the EPA estimates provide a useful starting point, real-world fuel economy for the Model X Long Range Plus can vary based on several factors. Driving style, climate, and terrain all play a role. Expect reduced efficiency in colder temperatures, as more energy is used to heat the cabin and battery pack. Frequent use of “Ludicrous” acceleration will also dramatically decrease range. Conversely, driving conservatively and using regenerative braking effectively can help you achieve or even exceed the EPA estimates. Remember that charging habits and access to superchargers on long journeys will also impact the overall ownership experience.

How it compares

The Model X Long Range Plus exists in a class of one, offering a unique combination of performance, passenger capacity, and all-electric operation. Comparing it to gasoline-powered, three-row SUVs reveals a stark contrast. For example, the Acura MDX SH-AWD achieves around 21 MPG combined, while the Volvo XC90 T6 AWD returns about 22 MPG. Even hybrid SUVs like the Toyota Highlander Hybrid LE manage only around 36 MPG combined. While these vehicles don’t demand buying a home charging station, the Model X’s dramatic advantage in fuel costs provides a good reason for those switching to electric vehicle technology. This is especially true for those who frequently shuttle passengers, travel long distances, and value cutting-edge technology.

Tips to maximize efficiency

Precondition your Tesla while it’s still plugged in, especially during cold weather. This warms the battery and cabin using grid power, preserving range for driving. Scheduling your charging to occur during off-peak hours can also drastically reduce your electricity bill.

Use regenerative braking effectively. Anticipate traffic flow and lift off the accelerator early, allowing the motor to slow the car while feeding energy back into the battery. The “one-pedal driving” mode maximizes this effect, making the Model X highly efficient in urban environments.

Minimize unnecessary cargo and drag. Removing roof racks and keeping your tires properly inflated will reduce aerodynamic drag and rolling resistance, improving overall efficiency. Even small changes can add up to noticeable improvements over time.

Plan your routes strategically, especially on long journeys. Use Tesla’s navigation system, which factors in elevation changes, traffic conditions, and Supercharger locations to optimize your energy consumption and minimize charging stops. Knowing where you can replenish helps mitigate range anxiety and ensures a smooth trip.
