Earning an EPA rating of 89 MPG combined, the 2016 Tesla Model X AWD – P90D wasn’t bought for its fuel efficiency, but this rating shows that this luxury SUV delivers blistering acceleration and exceptional practicality without burning any gas. This is a vehicle purchased by those prioritizing cutting-edge technology, performance, and lower fuel costs, not those focused on saving money at the gas pump.

City and highway performance

The Model X P90D demonstrates noticeable consistency across different driving environments, earning an EPA estimated 89 MPG in the city and 90 MPG on the highway. This near-identical performance comes from the inherent characteristics of electric powertrains, which operate with high efficiency in stop-and-go situations due to regenerative braking and minimal idling losses. Highway driving sees a slight dip in efficiency for most EVs, but the Model X P90D’s aerodynamic design and optimized motor management reduce this effect, maintaining excellent numbers regardless of setting.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Tesla Model X P90D at $850. This figure is based on driving 15,000 miles per year and using the national average electricity price at the time of testing. Electricity rates vary across the country and charging habits differ between owners, but this figure provides a valuable benchmark for comparing the operating costs of the Model X P90D against gasoline-powered vehicles. Individual charging costs can be reduced by using off-peak charging hours or solar panel installations.

Real-world expectations

The EPA ratings provide a standardized comparison, but real-world range and MPGe can vary depending on several factors. Aggressive driving, frequent use of “Ludicrous Mode,” carrying heavy loads, and extreme weather conditions can negatively impact efficiency. Conscientious driving habits, optimized tire pressures, and preconditioning the battery pack can help achieve or even exceed the EPA estimates. Battery degradation over time will gradually reduce the vehicle’s maximum range and efficiency too. Owners who meticulously track their energy consumption and adapt their driving habits will likely see the best results.

How it compares

The electric vehicle landscape has changed dramatically since 2016, but the Model X P90D still holds its own. Newer Tesla models and competitors offer improved range, but few can match the P90D’s blend of performance and practicality in its price range. The gasoline-powered Porsche Cayenne, a similarly sized performance SUV, typically achieves combined fuel economy in the low 20s MPG range. Even hybrid SUVs like the Lexus RX 450h, which boasts a combined 31 MPG, pale in comparison to the Model X P90D’s electric efficiency. Buyers looking at all Tesla fuel economy data know what they are getting.

Tips to maximize efficiency

Use regenerative braking modes. The Model X P90D offers adjustable regenerative braking settings. Selecting the highest regeneration level allows the vehicle to capture more energy during deceleration, extending your range, especially in city driving. Anticipate traffic conditions and lift off the accelerator early to maximize regenerative braking and minimize the need for friction brakes.

Precondition the battery before driving. Preconditioning warms or cools the battery pack while the vehicle is plugged in, which optimizes battery temperature for efficient operation. This is beneficial in extreme temperatures because it reduces the energy required to regulate battery temperature during driving. Scheduled departures via the Tesla app make preconditioning easy.

Maintain proper tire inflation. Properly inflated tires reduce rolling resistance, which can significantly improve efficiency. Check your tire pressures regularly, ideally, when the tires are cold, and inflate them to the recommended pressure listed on the doorjamb sticker. Underinflated tires not only decrease fuel economy but also increase tire wear.

Limit the use of accessories. High-power accessories like the air conditioner and heater consume significant amounts of energy. Use them carefully, especially in cold weather, which can substantially reduce range. Consider using seat heaters and the heated steering wheel instead of using the cabin heat to conserve energy.
