An 85 MPGe combined rating requires some adjustment when considering the 2019 Tesla Model X P100D. This isn’t a typical fuel economy rating, it’s the electric equivalent, showing how efficiently this high-performance SUV converts electricity into motion. The number appeals to a specific buyer who values fast acceleration, advanced technology, and a desire to reduce their environmental footprint, all within a distinctive package. These buyers willingly accept some quirks and compromises for the unique experience the Model X delivers.

City and highway performance

The EPA rates the 2019 Tesla Model X P100D at 83 MPGe in the city and 89 MPGe on the highway. That’s a small difference, showing that this vehicle’s efficiency isn’t greatly impacted by stop-and-go driving like a gasoline-powered car. Regenerative braking, a key feature of electric vehicles, recaptures energy when slowing down, sending it back to the battery. This is most effective in city driving, helping to narrow the gap between city and highway MPGe.

The highway figure, slightly higher, reflects more consistent speeds and less need for braking. Finally, the nearly identical ratings emphasize the Model X’s ability to maintain efficiency regardless of the driving environment.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Tesla Model X P100D at $900. This estimate is based on driving 15,000 miles per year and uses the national average electricity price at the time of calculation. It’s important data for potential buyers, offering a clear understanding of the running costs of electric vehicle ownership. This $900 figure, when compared to the thousands spent annually on gasoline for a similar performance SUV, supports the Model X, especially for those driving many miles. All Tesla fuel economy data shows these cost savings across models.

Real-world expectations

While the EPA estimates offer a useful baseline, real-world MPGe can change depending on several factors. Driving style is critical: fast acceleration and frequent use of the P100D’s power will reduce efficiency. Ambient temperature also matters, as extreme cold can affect battery performance. Using the climate control system, especially heating, can also draw significant power from the battery. However, most Model X owners find that the real-world MPGe stays close to the EPA estimates, especially with careful driving habits.

How it compares

When comparing, traditional performance SUVs don’t match the Model X P100D’s efficiency. The BMW X5 M achieves around 16 MPG combined. The Mercedes-AMG GLE 63 S Coupe is similar, around the low-to-mid teens. Even hybrid SUVs like the Lexus RX 450h, rated at 30 MPG combined, don’t approach the Tesla’s electric efficiency. For buyers considering the Model X, this comparison means lower fuel costs without losing performance. And if you broaden your search, you can also compare MODEL MPG across all years.

Tips to maximize efficiency

Preconditioning the cabin while the vehicle is plugged in can reduce energy consumption once driving. Use the Tesla app to set your desired temperature while the car is charging, using grid power for climate control instead of the battery.

Use regenerative braking. By lifting off the accelerator before stops, you’ll recapture energy and extend your range. Try the different regenerative braking settings to find the best level for your driving.

Reduce use of accessories. Features like seat heaters and defrosters can use significant power, mainly in cold weather. Use them only when necessary to improve efficiency.

Check your tire pressure regularly. Properly inflated tires reduce rolling resistance, improving efficiency. See the sticker on the driver’s side doorjamb for the recommended tire pressure.

Consider “Chill Mode” for everyday driving. This setting limits acceleration, preventing use of the P100D’s power and draining the battery. Reserve “Ludicrous Mode” for when needed.
