With 120 MPGe combined, the 2022 Tesla Model S is among the most efficient high-performance luxury sedans. To be clear, buyers likely want the Model S for its fast acceleration, modern technology, and as a statement about sustainable driving, but its great efficiency is part of the package and backs up the rationale for this expensive sedan.

City and highway performance

The EPA rates the 2022 Tesla Model S at 124 MPGe in the city and 115 MPGe on the highway. Electric vehicles usually perform slightly better in the city. Regenerative braking, which captures energy when slowing down, works much better in stop-and-go traffic than at steady highway speeds. These numbers allow for easy comparison, but keep in mind that weather, driving style, and terrain will greatly affect your actual results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Tesla Model S at $650. This is based on driving 15,000 miles per year and using national average electricity prices. Fluctuations in energy costs can affect that $650 price. Home charging, particularly with off-peak rates, can greatly reduce your expenses when compared to only using public charging stations.

Real-world expectations

While the EPA provides a standard for comparison, the real-world range and efficiency of a Tesla Model S can change a lot. Driving hard, often using “Ludicrous” mode, cold weather (which reduces battery capacity), and carrying heavy loads will all decrease your efficiency. On the other hand, eco-friendly driving, moderate temperatures, and fully using regenerative braking can help you more closely match, or even beat, the EPA estimates. Owners who install solar panels and charge their Model S with self-generated electricity can almost eliminate their “fuel” costs.

How it compares

The Model S is far more efficient than other high-performance luxury sedans. The Porsche Taycan Turbo S, a direct competitor in price and performance, is rated at just 69 MPGe combined. Even the more efficient Taycan 4S gets only 79 MPGe combined, according to the EPA. The Mercedes-Benz EQS 450+, another electric luxury sedan, achieves a combined rating of 97 MPGe, which is still much lower than the Model S. A gasoline-powered car, such as the BMW M5 Competition, gets just 17 MPG combined. This big difference in efficiency helps to justify the Model S’s high price for many buyers, especially those who want lower fuel costs or dislike frequent trips to gas stations.

Tips to maximize efficiency

Preconditioning the battery is critical in colder temperatures. Use the Tesla app to warm up the battery before you start driving. This will improve its efficiency and range.

Avoid quick acceleration and hard braking. Maintaining a steady speed and watching traffic will greatly reduce energy consumption.

Pay attention to your tire pressure. Proper inflation reduces rolling resistance and improves efficiency. Look at the sticker inside the driver’s side door for the recommended pressure. Regularly checking your tire pressure will help you keep good MPGe.

Effectively use regenerative braking. Try the different regeneration modes to find one that fits your style. Better regenerative braking allows you to recapture more energy to increase efficiency. Use One Pedal Driving mode when possible.

Reduce aerodynamic drag. Remove roof racks or cargo carriers when not in use, as they can greatly increase wind resistance. Limiting wind resistance will help retain optimal energy, but it will only benefit short trips.
