105 MPGe combined is a notable figure. Understanding what it truly represents in the 2020 Tesla Model X Long Range Plus requires appreciating the vehicle’s unique mission. This maximizing efficiency in a large, all-electric SUV designed for family transport, long-distance comfort, and performance. The Model X appeals to buyers who prioritize technology, lower fuel costs, and effortless torque over traditional metrics like miles per gallon. These buyers accept that the ‘fuel’ economy is dependent on their local electricity rates and charging habits.

City and highway performance

The EPA estimates provide a nuanced picture of the Model X Long Range Plus’s electric efficiency. The slightly higher city rating of 108 MPGe reflects the regenerative braking system’s effectiveness in stop-and-go situations. The system captures kinetic energy during deceleration, converting it back into electricity to recharge the battery. This reduces energy consumption compared to highway driving, where constant speed demands a steadier power draw. The highway rating of 101 MPGe is still impressive for a vehicle of this size and weight, indicating efficient aerodynamics and powertrain management at higher speeds.

Annual fuel cost

The EPA estimates the annual ‘fuel’ cost for the 2020 Tesla Model X Long Range Plus at $700. This figure is calculated based on 15,000 miles of driving per year, with a specific ratio of city and highway miles, applied against the national average electricity rates. Of course, your actual cost may vary depending on where you live. If you charge primarily during off-peak hours or have solar panels, your annual cost could be lower. If you rely solely on public charging networks during peak hours, your costs would go above the EPA estimate.

Real-world expectations

EPA estimates provide a useful baseline, but real-world MPGe can vary based on several factors. Aggressive driving, frequent hard acceleration, and carrying heavy loads will all decrease efficiency. Cold weather can reduce battery range, as the battery needs to expend energy to maintain its optimal operating temperature. Driving conservatively, preconditioning the cabin while plugged in, and using the vehicle’s energy-saving features will help you achieve figures closer to, or even exceeding, the EPA estimates. Factors like tire pressure and overall vehicle maintenance also play a role.

How it compares

Direct comparisons to gasoline SUVs are almost irrelevant, as the Model X exists in a different way of thinking about cars. Within the electric SUV segment, some context is useful. For maximum range, the Tesla Model Y Long Range, with its MPGe of 122, offers a similar experience in a smaller package. Consider the Audi e-tron, which offers a more conventional luxury SUV experience at a cost of 78 MPGe combined. To get something truly different with more towing capabilities, look at the Rivian R1S, which offers 73 MPGe. Buyers choose the Model X Long Range Plus not because it’s the most efficient electric SUV, but because it offers a combination of space, performance, technology, and brand appeal, all while reducing their dependence on fossil fuels.

Tips to maximize efficiency

Take advantage of Tesla’s regenerative braking settings. Experiment with “Standard” and “Low” settings to find what works best for your driving style. Maximizing regenerative braking means reducing your use of the friction brakes, extending their lifespan while replenishing the battery.

Plan your routes carefully, especially on long trips. Use Tesla’s navigation system, which factors in elevation changes and charging locations. Pre-planning enables you to optimize your speed and minimize unnecessary energy consumption. Also consider the MODEL MPG across all years when considering different Tesla offerings.

Precondition the cabin while the vehicle is plugged in. This heats or cools the interior using grid power instead of drawing energy from the battery while you’re on the road. This is helpful during extreme temperatures, when HVAC systems use the most energy.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which forces the motor to work harder and reduces efficiency. Maintaining the recommended tire pressure can improve your MPGe and extend tire life.

Avoid aggressive acceleration and high speeds. Rapid acceleration consumes a significant amount of energy, and aerodynamic drag increases exponentially with speed. Driving smoothly and maintaining a moderate pace will improve your overall efficiency.
