The 2017 Tesla Model X 60D has a combined EPA rating of 93 MPGe, a figure that requires context. This isn’t a gasoline car achieving 93 miles per gallon; it’s an all-electric SUV, and that number reflects the equivalent energy efficiency compared to a gasoline vehicle. For Model X buyers, typically affluent, tech-savvy, and families interested in lower fuel costs, that triple-digit number is a strong signal, reinforcing their commitment to sustainable transportation while still enjoying the practicality of a large SUV with distinctive falcon-wing doors.

City and highway performance

Breaking down the combined figure, the Model X 60D achieves 91 MPGe in the city and 94 MPGe on the highway. The slightly higher highway rating isn’t a surprise considering the regenerative braking system. In urban environments, frequent deceleration captures kinetic energy and feeds it back into the battery, boosting efficiency. Open-road driving relies more on maintaining a constant speed and showcasing the aerodynamic efficiency of the Model X as an SUV. These figures demonstrate a real world efficiency that rivals smaller EV’s, which is impressive for Tesla’s larger SUV.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Tesla Model X 60D is $800. This calculation assumes 15,000 miles driven per year, using the national average electricity price. This low figure is a major draw for Model X owners, as it represents significant savings compared to conventional gasoline-powered SUVs. Electricity costs can fluctuate depending on your location and charging habits. Charging at home, especially during off-peak hours, will likely reduce your actual annual cost below this EPA estimate. The ability to “fuel up” overnight in their garage is an important benefit for many owners.

Real-world expectations

While the EPA provides a standardized rating, real-world energy consumption depends on several factors. Driving aggressively, using heating or air conditioning excessively, and consistently travelling at high speeds will all decrease the effective MPGe and range. Conversely, driving conservatively, preconditioning the cabin while plugged in, and maximizing regenerative braking will help achieve or surpass the EPA estimates. Terrain also plays a role, especially when tackling steep hills or driving through mountainous regions, and ambient temperature matters, since extreme cold can impact battery performance. Tesla owners often meticulously track their energy usage through the vehicle’s onboard computer to constantly improve efficiency. Checking MODEL MPG across all years can provide further insight.

How it compares

Compared to other luxury SUVs, the Model X 60D’s 93 MPGe is far ahead. A comparable gasoline-powered SUV, such as the 2017 BMW X5 xDrive35i, achieves around 20 MPG combined. Even hybrid SUVs struggle to match the Tesla’s efficiency. The Lexus RX 450h, for example, manages 30 MPG combined. Only plug-in hybrid SUVs like the Volvo XC90 T8, around 66 MPGe combined, come close, but they still rely on gasoline for longer trips, diminishing their overall efficiency. This comparison is critical for the Model X buyer, who is often willing to pay a premium upfront to drastically reduce their environmental footprint and long-term running costs. All all Tesla fuel economy data showcases the advantages of electric propulsion.

Tips to maximize efficiency

Take advantage of regenerative braking. The Model X offers adjustable regenerative braking settings. Experiment to find a level that suits your driving style, allowing you to decelerate smoothly and recapture energy whenever possible. Anticipating traffic flow and lifting off the accelerator early will maximize this effect.

Precondition the cabin while plugged in. Heating or cooling the interior while the vehicle is connected to a charger draws power from the grid, not the battery, preserving range, especially in extreme temperatures. This simple step can significantly improve efficiency, particularly on shorter trips.

Monitor your tire pressure. Underinflated tires increase rolling resistance and reduce efficiency. Maintain the recommended tire pressure to optimize fuel economy and handling. The dashboard display makes this easy.

Limit high-speed driving. Aerodynamic drag increases exponentially at higher speeds, significantly impacting energy consumption. Moderate your speed, especially on the highway, to conserve energy and enjoy the relaxing pace and the longer driving range.

Optimize your route. Plan your journeys to avoid congested areas and maximize smooth, consistent driving. Using the Tesla navigation system is ideal, as it factors in real-time traffic conditions and can even suggest energy-efficient routes, while also keeping in mind charging locations along the way.
