97 MPG combined. That’s the official EPA figure for the 2019 Tesla Model S Performance with 21-inch wheels, and while it might seem like a typo when discussing a vehicle known for its fast acceleration, it’s due to the efficiency of electric powertrains. This isn’t your typical fuel economy story; it’s a look at how a specific type of buyer prioritizes performance without completely sacrificing lower fuel costs.

City and highway performance

The Model S Performance’s EPA ratings are remarkably consistent across different driving environments, achieving 98 MPG in the city and 96 MPG on the highway. This near-identical performance is a direct result of the electric motor’s characteristics. Unlike internal combustion engines that suffer efficiency losses at lower speeds and during stop-and-go traffic, the electric motor operates efficiently across a wide power band. Regenerative braking in city driving further enhances efficiency, recapturing kinetic energy and returning it to the battery. On the highway, the Model S maintains a steady state of efficiency, though aerodynamic drag does become a more significant factor at higher speeds. The important difference is that this efficiency always exists alongside instantaneous torque and supercar-rivaling acceleration. This car isn’t bought for its economy; it offers economy in spite of its performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Tesla Model S Performance (21in Wheels) at precisely $800. This calculation is based on driving 15,000 miles per year, factoring in a national average electricity cost. It’s important to understand this is an *estimate*. Your actual costs will vary based on your local electricity rates, driving habits, and how frequently you use Superchargers versus home charging. However, the $800 figure provides a valuable benchmark for comparing the Model S Performance to gasoline-powered vehicles in its performance class. This figure is also highly dependent on whether the owner is charging at home, or at Supercharger networks. Those with home charging capability and off-peak electricity rates will likely pay far less than $800 per year.

Real-world expectations

While the EPA numbers provide a standardized comparison, real-world range and efficiency for the Model S Performance are influenced by several factors. Aggressive acceleration, high speeds, and cold weather can all significantly reduce the car’s range compared to the EPA estimates. Conversely, gentle acceleration, moderate speeds, and warmer temperatures can extend the range. Owners who prioritize hypermiling techniques might even exceed the official EPA figures.

It’s more useful to think of the 97 MPG figure as a baseline, and then adjust your expectations based on your individual driving style and environmental conditions. Also important is degradation of the high-voltage battery over time and mileage; the battery’s ability to hold a charge deteriorates over time. Be sure to consult all Tesla fuel economy data before making any purchase decisions.

How it compares

Compared to other high-performance vehicles, the 2019 Tesla Model S Performance (21in Wheels) is in a league of its own in terms of efficiency. A comparable gasoline-powered sedan in terms of performance, like the BMW M5 Competition, achieves only around 17 MPG combined. Even a hybrid performance sedan like the Porsche Panamera 4 E-Hybrid manages only around 22 MPG combined when running on gasoline alone. The fully electric powertrain of the Model S Performance provides a massive advantage in terms of energy consumption. For buyers who desire both blistering acceleration and less gas, the Model S Performance is a great choice, whereas typical buyers of similar performing cars like the Mercedes-AMG E63 S (19 MPG combined) are far less mindful of fuel consumption. The ability to check MODEL MPG across all years is an invaluable tool for prospective buyers.

Tips to maximize efficiency

One of the easiest ways to extend your Model S Performance’s range is to pre-condition the battery. While plugged in, use the Tesla app to warm up or cool down the cabin before driving. This will minimize the amount of energy the car needs to use from the battery to maintain a comfortable temperature while driving, particularly in extreme weather conditions.

Regenerative braking is a crucial feature for maximizing efficiency in the Model S. Choose the “Standard” regenerative braking setting to maximize energy capture during deceleration. This setting allows for “one-pedal driving,” where lifting off the accelerator slows the car down significantly, reducing the need to use the brake pedal and converting kinetic energy back into battery power.

Aerodynamic drag increases exponentially with speed, so maintaining moderate speeds on the highway can significantly improve your range. Consider using the car’s adaptive cruise control to maintain a consistent speed and avoid unnecessary acceleration and braking. Even small reductions in speed can lead to noticeable improvements in efficiency.

Keep tires properly inflated. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces efficiency and range. Conversely, overinflated tires can cause a harsher ride, worse handling, and may degrade the life of the tire.
