The 2019 Tesla Model X 100D earns an EPA-estimated 87 MPG combined and redefines efficiency for a large, all-wheel-drive SUV. This seven-passenger tech showcase can launch to 60 mph in under five seconds while emitting zero tailpipe emissions. This MPG figure is a key reason why affluent families interested in lower fuel costs flock to the Model X, accepting its premium price for guilt-free performance and a glimpse into the future of driving.

City and highway performance

The Model X 100D’s electric powertrain performs well in both city and highway driving, earning an impressive EPA rating of 86 MPG in the city and 89 MPG on the highway. This minimal difference shows the efficiency of electric motors, which don’t lose efficiency at low speeds like internal combustion engines. Regenerative braking, which recovers energy during deceleration, is especially effective in stop-and-go city traffic and helps create the high city MPG rating. The slight dip in highway MPG is typical for electric vehicles, as aerodynamic drag increases at higher speeds, but the Model X’s sleek design and efficient motors still allow for excellent long-distance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Tesla Model X 100D at just $850. This calculation is based on driving 15,000 miles per year and using the national average electricity prices at the time of calculation. This low figure highlights the significant savings potential of electric vehicles compared to gasoline-powered vehicles, especially for drivers who log a lot of miles.

Of course, your actual electricity costs may vary based on your local utility rates, driving habits, and charging patterns. Even with higher electricity prices, the Model X 100D will likely offer fuel savings compared to a comparable luxury SUV.

Real-world expectations

While the EPA provides a standardized measure of efficiency, real-world MPG for the Model X 100D can vary. For instance, aggressive driving, frequent use of “Ludicrous” mode, carrying heavy loads, and extreme weather conditions can all reduce efficiency.

On the other hand, gentle acceleration, strategic use of regenerative braking, and preconditioning the battery while plugged in can help you achieve or exceed the EPA estimates. Owners who pay attention to their driving habits and charging practices often report energy consumption close to the official figures, validating the Model X 100D’s efficiency.

How it compares

The 2019 Tesla Model X 100D has excellent fuel economy compared to other luxury SUVs. For example, a gasoline-powered alternative like the BMW X5 xDrive40i achieves around 23 MPG combined. Even the hybrid Lexus RX 450h only manages around 30 MPG combined. The Model X’s all-electric powertrain offers efficiency that these vehicles cannot match.

For buyers prioritizing fuel economy and environmental responsibility, the Model X 100D’s superior figures are often a deciding factor and justify its higher initial cost. Anyone wanting to see all Tesla fuel economy data can compare these numbers themselves.

Tips to maximize efficiency

Take advantage of regenerative braking. The Model X offers adjustable regenerative braking settings, experiment to find the level that best suits your driving style. Using regen will recapture energy during deceleration, extending your range and minimizing energy consumption. Become familiar with one-pedal driving, which allows you to control the vehicle’s speed almost entirely with the accelerator pedal, maximizing the use of regenerative braking.

Precondition the battery. In cold weather, preconditioning the battery while the vehicle is plugged in can improve range. This warms the battery pack using grid power instead of drawing energy from the battery itself. In hot weather, pre-cooling the cabin while plugged in helps reduce the energy needed to maintain a comfortable temperature while driving.

Optimize driving speed on the highway. Aerodynamic drag increases exponentially with speed. Reducing your cruising speed by even a few miles per hour can affect energy consumption. Use the Tesla’s trip planner to estimate energy consumption and plan charging stops for longer road trips.

Monitor tire pressure regularly. Properly inflated tires reduce rolling resistance and improve efficiency. Check your tire pressure regularly and maintain the pressure specified in the owner’s manual. Consider using low-rolling-resistance tires when it’s time for replacement to enhance efficiency. Research MODEL MPG across all years to see how tire choice can affect efficiency over the long run.

Minimize unnecessary weight. Carrying unnecessary cargo increases energy consumption. Remove any items from the vehicle that you don’t need to carry regularly. Even small weight reductions can add up and improve efficiency.
