92 MPG combined is an impressive figure for the 2016 Tesla Model X AWD – 90D. Achieving that rating in a seven-passenger, all-wheel-drive crossover that performs like a sports car is quite an accomplishment. Let’s look at what this number means.

City and highway performance

The Model X 90D’s official EPA figures show balanced performance. City driving achieves 90 MPG, while highway driving sees a slight increase to 94 MPG. This similarity reflects the electric powertrain’s efficiency. Unlike gasoline engines that often lose efficiency in stop-and-go city conditions, the Model X uses regenerative braking to recapture energy during deceleration, improving city MPG. The slightly better highway figure suggests the electric motor operates closer to its best efficiency at consistent speeds, although aerodynamic drag eventually becomes a factor at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Tesla Model X 90D at $850. This figure is based on driving 15,000 miles per year, with a percentage of city versus highway miles (typically 55% city, 45% highway) and using national average electricity prices. Actual costs will vary depending on electricity rates and charging habits. However, $850 is significantly less than the annual fuel expenses of comparable luxury SUVs, which often cost thousands of dollars, even with relatively efficient gasoline engines.

Real-world expectations

The EPA numbers provide a benchmark, but real-world driving conditions matter. Aggressive acceleration, frequent use of “Ludicrous Mode,” carrying heavy loads, and extreme weather (especially cold temperatures, which reduce battery efficiency) can decrease your mileage. However, careful driving, strategic use of regenerative braking, and pre-heating the cabin while plugged in can help you get closer to, or even exceed, the EPA estimates.

Battery degradation over time can also gradually reduce the vehicle’s range and efficiency, a factor that affects all Tesla fuel economy data.

How it compares

Compared to other vehicles, the 2016 Tesla Model X 90D stands apart. Traditional gasoline-powered luxury SUVs can’t approach these efficiency numbers. For example, the 2016 BMW X5 xDrive35i achieves only 20 MPG combined. Even hybrid SUVs like the Lexus RX 450h (30 MPG combined) fall short. This contrast is a large part of the Model X’s appeal, especially for buyers seeking a large and luxurious vehicle without the fuel consumption penalty. Owners of the Model X might also want to consult MODEL MPG across all years to compare different configurations of the vehicle.

Tips to maximize efficiency

One key to maximizing range in the Model X is to master regenerative braking. Anticipate stops and ease off the accelerator early, allowing the motor to recapture energy and reduce the need to use the friction brakes. This extends your range and reduces wear and tear on the brake pads.

Pre-heating or pre-cooling the cabin while the car is plugged in can conserve energy, especially in extreme temperatures. By drawing power from the grid instead of the battery, you avoid depleting the battery’s charge before you even start driving.

Moderate your driving style. The Model X’s instant torque is exciting, but frequent hard acceleration reduces range. Smooth, consistent acceleration and maintaining a steady speed will yield the best efficiency.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, improving overall efficiency. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels (found on a sticker inside the driver’s side door jamb).

Reduce unnecessary weight, as carrying extra cargo can decrease range. Remove any items you don’t need to lighten the load and improve efficiency. Minimizing weight is very helpful for long road trips.
