89 MPG combined. While technically accurate according to the EPA, that figure only hints at what the 2017 Tesla Model X AWD – P90D offers. This isn’t about saving money on gas; it’s about high-performance electric driving in a family-friendly vehicle with falcon-wing doors. The buyer of a P90D prioritizes rapid acceleration, advanced technology, and a commitment to electric power, accepting the energy consumption that comes with it. The 89 MPG figure is more representative of this electric commitment than of a traditional combustion engine vehicle’s efficiency.

City and highway performance

The EPA estimates the 2017 Tesla Model X P90D at 89 MPG in the city and 90 MPG on the highway. While seemingly similar, these numbers don’t fully explain how an electric vehicle like the Model X behaves in different driving conditions. In city driving, the Model X benefits from regenerative braking, which captures kinetic energy and recharges the battery. This is why the city MPG mirrors the combined figure. On the highway, where there’s less regenerative braking, the Model X relies more on sustained power delivery which slightly impacts its efficiency. However, the difference is minimal, showing the electric powertrain’s efficiency, even at higher speeds. The aerodynamic profile also helps highway efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Tesla Model X P90D at $850. This is based on driving 15,000 miles per year, using a national average electricity cost. This can vary depending on local electricity rates and driving habits. Charging during off-peak hours can reduce energy costs. The $850 figure is a benchmark, highlighting potential savings compared to gasoline-powered SUVs, where fuel costs can easily reach two or three times that amount. While electricity rates fluctuate, the overall expense is frequently lower than gasoline.

Real-world expectations

While the EPA provides a baseline, real-world energy consumption can vary. Driving style, temperature, and climate control all influence the Model X P90D’s range and efficiency. Aggressive acceleration and “Ludicrous Mode” will deplete the battery faster than conservative driving. Cold weather can also reduce battery performance. Air conditioning or heating will draw power and reduce range. To ensure the best performance, plan routes, preconditioning the battery and using Tesla Supercharger stations.

How it compares

Comparing the 2017 Tesla Model X P90D to gasoline-powered SUVs shows its strengths, even if MPG comparisons are skewed. A 2017 BMW X5 xDrive50i, for example, gets around 17 MPG combined. A comparable Mercedes-Benz GLE 550e plug-in hybrid achieves around 21 MPG combined when running on gasoline, despite being a hybrid. The Model X P90D’s 89 MPG equivalent is competitive in “fuel” cost and environmental impact. What appeals to the Tesla buyer is the shift away from gasoline. Potential buyers might also be interested in all Tesla fuel economy data or other MODEL MPG across all years.

Tips to maximize efficiency

Adopt a smooth driving style. Avoid sudden acceleration and braking, anticipate traffic flow, and maintain a consistent speed. This will maximize regenerative braking and extend range.

Precondition the battery before departures, especially in cold weather. Use the Tesla app to remotely heat or cool the cabin while the vehicle is still plugged in. This reduces the energy drain on the battery.

Monitor tire pressure regularly. Underinflated tires create more rolling resistance, which increases energy consumption. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and maintain it.

Use the Tesla energy app to monitor your usage. This tool provides real-time feedback on your energy consumption and offers insights into how different driving behaviors and vehicle settings impact range.

Plan road trips carefully to take advantage of the Tesla Supercharger network. Locate charging stops along your route, factoring in charging times and distances between stations. This minimizes range anxiety.
