93 MPGe combined is a remarkable figure for the 2018 Tesla Model X 75D, and it’s important to understand what it represents. This isn’t a gasoline statistic; it’s a miles-per-gallon equivalent, reflecting how efficiently the Model X’s electric motor works compared to a gasoline vehicle. Consider that the Model X is a large, seven-passenger crossover with all-wheel drive, packing a heavy battery pack. This rating shows Tesla’s engineering and the inherent efficiency of electric power.

City and highway performance

The EPA rates the 2018 Tesla Model X 75D at 91 MPGe in the city and 95 MPGe on the highway. This near-identical performance in both environments reflects how electric motors work. Unlike internal combustion engines, electric motors provide instant torque and operate efficiently across a wide range of speeds. In city driving, the Model X benefits from regenerative braking, which captures kinetic energy during deceleration and returns it to the battery, boosting efficiency. On the highway, the Model X’s aerodynamic design and single-speed transmission contribute to its impressive rating. These numbers demonstrate that efficiency isn’t compromised, whether you are commuting through stop-and-go traffic or cruising down the open road. For buyers who prioritize consistent, predictable efficiency, the Model X delivers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Tesla Model X 75D to be $800. This figure is based on driving 15,000 miles per year and using the national average electricity price. Of course, your actual cost will vary depending on your local electricity rates and your driving habits. However, $800 is a good value, especially when compared to gasoline-powered SUVs of similar size and capability. Over the lifespan of the vehicle, you can potentially save thousands of dollars on fuel alone, making the slightly higher initial purchase price of a Model X more palatable. The figure also does not take into account government incentives related to buying electric vehicles.

Real-world expectations

While the EPA ratings provide a standardized benchmark, real-world range and efficiency can fluctuate based on several factors. Driving style, weather conditions, and terrain all play a role. Aggressive acceleration and high speeds consume more energy, while cold weather can reduce battery performance. However, most Model X owners report that the EPA estimates are reasonably accurate under normal driving conditions. Intelligent energy management and the ability to monitor energy consumption in real time via the car’s display screen helps to keep the numbers consistent. Mindful drivers will be rewarded with predictable and reliable efficiency.

How it compares

The 2018 Tesla Model X 75D stands apart from its gasoline-powered rivals in terms of fuel economy. Consider the BMW X5 xDrive40i, which achieves around 22 MPG combined, or the Volvo XC90 T6 AWD showing roughly 23 MPG combined. Those are large differences. The Model X buyer isn’t cross-shopping these vehicles. They are sold on the electric ecosystem and the substantial reduction in running costs it provides. For those considering a practical SUV with an eye on the environment and a desire minimize trips to the gas station, the Model X is in a class of its own.

Tips to maximize efficiency

Use regenerative braking. This feature captures energy during deceleration and sends it back to the battery, extending your range. Experiment with “Standard” and “Low” settings to find what fits your driving style. The “Low” setting allows for more traditional “coasting” and is a good option for drivers who find one-pedal-driving difficult to master.

Precondition the cabin while the vehicle is plugged in. Heating or cooling the interior while connected to the grid reduces the energy demand on the battery once you start driving. Program your departure time in the Tesla app, and the car will automatically precondition the cabin for optimal efficiency.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which reduces efficiency. Check your tire pressure regularly and inflate them to the recommended level. Pay close attention to this as temperatures change throughout the year.

Minimize aerodynamic drag. Remove unnecessary items from the roof rack and avoid driving at excessively high speeds. At higher speeds, aerodynamic drag increases exponentially, consuming more energy.

Plan your routes strategically. When possible, choose routes that minimize elevation changes and stop-and-go traffic. Use the Tesla navigation system to identify charging locations along your route and estimate arrival times with consideration of energy consumption.
