The 2015 Tesla Model S AWD P90D gets a combined fuel economy of 93 MPG, a remarkable achievement for a high-performance, all-wheel-drive sedan designed for fast acceleration and comfortable luxury. It’s about enjoying supercar-level performance without the fuel consumption guilt. The P90D buyer wants instant torque and advanced technology, accepting charging limitations for early adoption and a thrilling driving experience.

City and highway performance

The EPA estimates the Model S P90D at 89 MPG in the city and 98 MPG on the highway. These are impressive numbers, but understanding electric vehicle (EV) operation is important. City driving, with frequent stops and regenerative braking, typically gets efficiency closer to the EPA estimate. Highway driving, especially at higher speeds, needs more energy to overcome aerodynamic drag, and range can decrease more significantly. The P90D has a large battery, so the difference in city versus highway driving is small.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Tesla Model S AWD P90D at $800. This is based on driving 15,000 miles per year and using the national average electricity price at the time of calculation. Actual electricity expenses will vary depending on your local utility rates, driving habits, and charging patterns. Charging at home during off-peak hours can lower your costs compared to using public charging networks.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG for the P90D will fluctuate. Aggressive driving, using “Ludicrous Mode” often, and heavy loads will all reduce efficiency. Ambient temperature also matters because battery performance is affected by extreme temperatures. Most owners report figures close to the EPA estimates under normal driving. EV “fuel economy” depends highly on driving style.

How it compares

The 93 MPG combined rating of the 2015 Tesla Model S P90D beats gasoline-powered performance sedans. A 2015 BMW M5 gets just 17 MPG combined, and a 2015 Mercedes-AMG E63 S manages only 18 MPG. Even hybrid vehicles in the same price range struggle; a 2015 Porsche Panamera S E-Hybrid achieves 50 MPG combined using both electric and gasoline power. The P90D is efficient while delivering comparable performance and luxury, showcasing the advantages of electric propulsion for drivers wanting both speed and lower fuel costs.

Tips to maximize efficiency

Regenerative braking is important. The P90D’s regenerative braking system captures energy when you slow down, sending it back to the battery to extend your range. Using “Low” or “Standard” regen settings, especially in city driving, will improve your overall efficiency.

Optimize your charging habits. Charge your P90D at home during off-peak hours to get lower electricity rates. Avoid frequently charging to 100% unless needed for a long trip because keeping a charge level between 20% and 80% is generally better for long-term battery health and efficiency.

Precondition the cabin. Use the Tesla app to preheat or precool the cabin while the car is plugged in. This reduces the energy drain on the battery when you start driving, particularly in very hot or cold weather. The energy used is drawn from the charger and not your vehicle’s battery.

Minimize aerodynamic drag. The P90D is already aerodynamic, but you can improve efficiency by ensuring your tires are properly inflated and avoiding roof racks or cargo carriers. High speeds always reduce fuel economy, so avoid excessive speeding when possible.

Plan your routes strategically. If you’re taking a long trip, use the Tesla navigation system to plan your route and find Supercharger locations. The navigation system optimizes your driving for maximum range and provides accurate arrival time and charging estimates.
