97 MPG combined. That’s the headline for the 2020 Tesla Model S Performance with 21-inch wheels, a figure that might seem absurd for a vehicle capable of launching to 60 mph in under three seconds. This is a Tesla, and that MPG equivalent, more accurately, MPGe, reflects its electric powertrain and the priorities of its buyers. These aren’t your typical fuel-sipping hatchback owners. They’re performance enthusiasts, tech aficionados, and early adopters who value blistering acceleration and cutting-edge technology as much as, if not more than, outright efficiency. They accept the nuances of electric vehicle ownership because the Model S Performance delivers a driving experience simply unavailable elsewhere.

City and highway performance

The EPA estimates the 2020 Tesla Model S Performance at 98 MPGe in the city and 96 MPGe on the highway. While electric vehicles often excel in city driving due to regenerative braking, the Model S Performance maintains impressive efficiency at highway speeds. This is partly due to Tesla’s focus on aerodynamic efficiency and the instant torque delivery that minimizes energy waste during acceleration. The relatively minor difference between city and highway MPGe figures suggests the Model S Performance’s drivetrain operates efficiently across a wide range of driving conditions. Still, aggressive driving and excessive use of the car’s prodigious power will naturally reduce real-world efficiency, even in an electric vehicle.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Tesla Model S Performance is $800. This figure is based on driving 15,000 miles per year and using national average electricity prices. It’s a useful benchmark for comparing running costs to gasoline-powered vehicles, though your actual cost will vary significantly depending on your electricity rates, driving habits, and charging patterns. Those who can charge primarily at home during off-peak hours will likely pay considerably less than the EPA estimate. $800 per year to fuel a vehicle with supercar-rivaling performance is undeniably attractive.

Real-world expectations

While the EPA figures provide a standardized comparison, real-world MPGe for any electric vehicle depends on numerous factors. Ambient temperature plays a critical role, as cold weather can significantly reduce battery range and efficiency. Driving style is also important. Consistent use of the Model S Performance’s launch mode will undoubtedly lower your MPGe. Frequent highway driving at high speeds will impact efficiency due to increased aerodynamic drag. Expect a slight reduction compared to the EPA estimates if you regularly face extreme temperatures or have a lead foot. For more information, you can compare MODEL MPG across all years.

How it compares

Compared to other high-performance vehicles, the 2020 Tesla Model S Performance stands in a league of its own. Consider the Porsche Taycan Turbo S, another high-performance EV. While the Taycan delivers a similar driving experience, its EPA-estimated combined MPGe is around 69. Gasoline-powered alternatives like the BMW M5 Competition achieve around 17 MPG combined, highlighting the efficiency advantage of the Tesla. Even hybrid performance cars struggle to match the Model S Performance’s efficiency. The Acura NSX, for example, manages only 21 MPG combined. Choosing the Model S Performance is a decisive statement about priorities, placing emission-free performance above traditional metrics.

Tips to maximize efficiency

Use regenerative braking aggressively. The Model S Performance offers adjustable regenerative braking settings. Selecting the highest setting allows for significant energy recapture when decelerating, effectively extending your range. Anticipate traffic flow and lift off the accelerator early to maximize this effect, turning kinetic energy back into battery charge.

Precondition the battery before driving, especially in cold weather. Use the Tesla app to warm the battery while the car is still plugged in. This minimizes the energy draw required to heat the battery during your drive and improves overall efficiency.

Optimize tire pressure. Ensure your tires are inflated to the recommended pressure listed on the doorjamb sticker. Underinflated tires increase rolling resistance, reducing efficiency and range. Regular tire pressure checks are particularly important for high-performance vehicles.

Minimize aerodynamic drag. Remove roof racks or carriers when not in use, as they significantly increase drag and reduce highway efficiency. Consider the impact of added weight as well. Carrying unnecessary cargo will reduce efficiency, though the effect is less pronounced than in a gasoline car.

Consider aftermarket wheels with less rolling resistance. While the 21-inch wheels look fantastic, they can hurt efficiency. Swapping to lighter wheels that are aerodynamically optimized for efficiency can improve range. You can check all Tesla fuel economy data for the standard wheel size of the Model S.
