120 MPG combined is a staggering figure for the 2023 Tesla Model S, a vehicle that prioritizes performance and technology over traditional notions of fuel efficiency. This isn’t your average hypermiler; it’s a high-performance electric sedan capable of fast acceleration and long-range cruising. Buyers drawn to the Model S are typically motivated by its modern technology, minimalist design, and its ability to bypass gasoline stations altogether. The impressive MPG equivalent (MPGe) is simply a welcome bonus.

City and highway performance

The EPA rates the 2023 Tesla Model S at 124 MPGe in the city and 115 MPGe on the highway. These figures reflect the efficient nature of electric powertrains, which excel in stop-and-go traffic, using regenerative braking to recapture energy that would otherwise be lost as heat. Highway driving also benefits from the Model S’s aerodynamic design and efficient electric motors, though higher speeds do necessitate more energy consumption to overcome air resistance. Expect these numbers to fluctuate in the real world, depending on driving style, ambient temperature, and the use of features like climate control.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Tesla Model S at precisely $650. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and assumes the national average electricity price. For many Model S owners, this represents a significant saving compared to similarly sized and performing gasoline-powered vehicles. Of course, actual electricity costs will vary depending on location, time of use, and charging habits, but the inherent price advantage of electricity over gasoline generally holds.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPGe for the 2023 Tesla Model S can vary. Fast acceleration and high-speed driving will deplete the battery more quickly, reducing overall efficiency. Conversely, gentle acceleration, consistent speeds, and strategic use of regenerative braking can extend range and improve MPGe. Factors such as cold weather, which can reduce battery performance, and loading the vehicle with passengers and cargo can also impact efficiency. Owners can monitor their energy consumption through the Tesla’s energy app, which provides real-time data and insights into driving habits.

How it compares

Comparing the 2023 Tesla Model S to traditional gasoline-powered vehicles highlights its efficiency advantage. A similarly sized and performing luxury sedan, like a BMW M5, achieves around 17 MPG combined. Even hybrid vehicles struggle to match the Model S’s overall efficiency. The Lexus ES 300h, a popular hybrid sedan, achieves 44 MPG combined. Examining MODEL MPG across all years reveals the Model S consistently leads its class in efficiency. The Porsche Taycan, another high-performance electric sedan, achieves around 79 MPGe combined, further solidifying the Model S’s edge in electric efficiency. Understanding all Tesla fuel economy data proves that the company strives for class-leading results.

Tips to maximize efficiency

Optimize regenerative braking settings within the Tesla’s menu. Selecting the “Standard” or “High” regeneration mode will slow the car more aggressively when lifting off the accelerator, converting kinetic energy back into electricity and extending your range. Get comfortable with one-pedal driving, using only the accelerator for most acceleration and deceleration.

Precondition the battery while the car is plugged in, particularly during cold weather. Using the Tesla app, you can warm the battery pack to its optimal operating temperature before driving, conserving energy that would otherwise be used to heat the battery during your trip. Similarly, preheating or precooling the cabin while plugged in will reduce the load on the climate control system once you’re on the road.

Monitor tire pressure regularly and keep tires properly inflated. Underinflated tires increase rolling resistance, which requires more energy to maintain speed. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure and check it frequently, especially as temperatures fluctuate.

Minimize aerodynamic drag by removing unnecessary roof racks or cargo carriers when not in use. Even subtle changes to the vehicle’s profile can impact its aerodynamic efficiency, especially at higher speeds.

Plan your routes strategically, using the Tesla’s navigation system to identify charging locations and optimize your driving speed. The Tesla navigation system takes into account elevation changes, traffic conditions, and other factors to calculate the most efficient route, helping you maximize range and minimize energy consumption.
