93 MPGe combined is a strong number for the 2017 Tesla Model X AWD, 75D. It’s a seven-passenger, all-wheel-drive crossover with Falcon Wing doors and advanced tech features. Buyers considering this vehicle are interested in electric vehicle (EV) technology and lower fuel costs.

City and highway performance

The 2017 Model X 75D achieves 95 MPGe on the highway and 91 MPGe in the city. This might seem unexpected, because EVs often perform well in city driving due to regenerative braking. The Model X’s aerodynamics improve efficiency for long freeway stretches. The Falcon Wing doors’ design could add weight, increasing energy consumption during city starts and stops. These numbers show that driving habits and environment affect real-world energy consumption, even with the Model X’s advanced powertrain.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Tesla Model X 75D at $800. This estimate is based on driving 15,000 miles per year in mixed city and highway conditions and using the national average electricity price. Costs will vary depending on location, as electricity prices change across the country. The figure could be significantly lower in areas with inexpensive electricity or access to free charging. Areas with high electricity rates will have higher yearly costs. Actual driving habits and charging patterns also affect electricity consumption. For example, aggressive driving lessens range, and using high-speed public chargers increases fueling expenses.

Real-world expectations

EPA estimates provide a baseline, but real-world MPGe for the Model X 75D can change. Temperature is important. Cold weather reduces battery performance and can decrease range by 20-30%. Driving style also affects it. Frequent hard acceleration and high-speed cruising use more battery power. Climate control use also affects range. Battery degradation over time will gradually reduce the car’s maximum range, which is a normal part of EV ownership.

How it compares

Comparisons to gasoline-powered SUVs aren’t useful, since Model X shoppers are interested in electric vehicles. The Audi e-tron SUV gets 78 MPGe combined, which is less than the Model X. It offers a traditional luxury SUV experience. The Jaguar I-PACE gets 76 MPGe combined, and it emphasizes sporty handling. But these EVs don’t have the Model X’s space and available seven-passenger seating. For buyers who want to see all Tesla fuel economy data, Tesla’s Model Y Long Range achieves 122 MPGe combined. This shows the compromises in vehicle design; the Model X prioritizes space over efficiency, while the Model Y prioritizes range and efficiency in a smaller package. For a look at MODEL MPG across all years, the Model X provides great efficiency.

Tips to maximize efficiency

Regenerative braking can make a big difference. The Model X lets you change the level of regenerative braking. Maximize this in city driving to capture energy when slowing down. Gently lifting off the accelerator instead of braking hard can increase range.

Precondition the battery. Before driving, especially in cold weather, precondition the battery and cabin using the Tesla app. This warms the battery when plugged in, reducing the energy needed from the battery when driving.

Tire pressure is important. Maintaining proper tire pressure reduces rolling resistance, improving efficiency. Check tire pressure regularly and inflate tires to the recommended levels, found on the doorjamb sticker.

Reduce drag. Remove roof racks or cargo carriers that create aerodynamic drag. These can affect energy consumption at highway speeds.

Plan your routes. Know the locations of charging stations along your route, especially on long trips. Use the Tesla navigation system, which includes charging stops in route planning and preconditions the battery for fast charging.
