Fuel economy at a glance
These are the EPA's official ratings for the 2020 Tesla Model S Long Range. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 111 MPG |
| City MPG | 115 MPG |
| Highway MPG | 107 MPG |
| Annual fuel cost | $700 |
| Tailpipe CO₂ | — |

How the 2020 Tesla Model S Long Range compares
The 2020 Tesla Model S Long Range returns 111 combined MPG. Cars in the Large Cars class for the same model year average 29.8 MPG, which puts this car ahead of the class average by about 272%.
The most efficient car in the Large Cars class for the 2020 model year is the Tesla Model S Long Range Plus at 117 MPG. The bar chart below puts the Tesla Model S Long Range alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2020 model year (across all classes) returns 27.2 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2020 model year is on its own page.
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for electricity, which is $0.15/kilowatt-hour. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPGe and the reference electricity price stay constant, only the annual mileage changes. Charging at home rather than at a public DC fast charger usually lowers the real cost below the EPA's published figure.
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $350 |
| Average driver, 15,000 miles per year | $700 |
| Heavy driver, 25,000 miles per year | $1,167 |
Year-over-year MPG for the Tesla Model S Long Range
The EPA has rated the Tesla Model S Long Range across 3 model years, from 2019 Tesla Model S Long Range through 2021 Tesla Model S Long Range. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.
The 2019 Tesla Model S Long Range returned 111 MPG. The most recent 2021 Tesla Model S Long Range returns 120 MPG. That is an improvement of 9 MPG over 2 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.
| Year | Combined MPG | Open year page |
|---|---|---|
| 2021 | 120 MPG | 2021 Tesla Model S Long Range |
| 2020 | 111 MPG | this page |
| 2019 | 111 MPG | 2019 Tesla Model S Long Range |

Specifications
The 2020 Tesla Model S Long Range is a fully electric vehicle. It is powered by 193 and 205 kw ac 3-phase. The EPA rates its driving range at 373 miles.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

Common questions about the 2020 Tesla Model S Long Range
Quick answers to the questions people most often search for when looking up the 2020 Tesla Model S Long Range.
-
Is the 2020 Tesla Model S Long Range fuel efficient?
Yes. The 2020 Tesla Model S Long Range returns 111 combined MPG, which beats the average car in the Large Cars class for the same model year by about 272%. -
What MPG does the 2020 Tesla Model S Long Range get?
The EPA rates the 2020 Tesla Model S Long Range at 111 combined MPG, 115 MPG in city driving, and 107 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is. -
How much does it cost to fuel a 2020 Tesla Model S Long Range per year?
The EPA estimates an annual fuel cost of $700 for the 2020 Tesla Model S Long Range. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade. -
Does the 2020 Tesla Model S Long Range use gasoline?
No. The 2020 Tesla Model S Long Range is fully electric and runs on grid electricity. The MPGe figure on this page converts electricity use into a gasoline-equivalent so you can compare it directly to a regular car. -
Has the Tesla Model S Long Range become more fuel efficient over time?
Yes. The first EPA-rated Tesla Model S Long Range, the 2019 Tesla Model S Long Range, returned 111 combined MPG. The most recent 2021 Tesla Model S Long Range returns 120 MPG, an improvement of 9 MPG over the run. -
How much CO₂ does the 2020 Tesla Model S Long Range emit?
The 2020 Tesla Model S Long Range produces zero tailpipe emissions because it runs entirely on electricity. The full carbon footprint of charging it depends on how the electricity on your local grid is generated, which varies a lot from one state to another. -
What is the difference between the city and highway MPG of the 2020 Tesla Model S Long Range?
City driving returns 115 MPG and highway driving returns 107 MPG. A flat (or city-better) split is the signature of a hybrid or electric drivetrain, where regenerative braking recovers energy that would otherwise be lost in stop-start city traffic. -
What motor does the 2020 Tesla Model S Long Range use?
The 2020 Tesla Model S Long Range uses 193 and 205 kW AC 3-Phase. Electric motors do not have a displacement or cylinder count the way a combustion engine does, so EPA reporting focuses on the motor type and battery system instead. -
What transmission and drivetrain does the 2020 Tesla Model S Long Range have?
The 2020 Tesla Model S Long Range comes with a automatic (a1) transmission and all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss. -
How does the 2020 Tesla Model S Long Range compare to the best car in its class?
The most efficient car in the Large Cars class for the 2020 model year is the Tesla Model S Long Range Plus at 117 combined MPG. The Tesla Model S Long Range returns 111 MPG, a gap of 6 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
