Fuel economy at a glance
These are the EPA's official ratings for the 2015 Tesla Model S AWD - P90D. 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 | 93 MPG |
| City MPG | 89 MPG |
| Highway MPG | 98 MPG |
| Annual fuel cost | $800 |

How the 2015 Tesla Model S AWD - P90D compares
The 2015 Tesla Model S AWD - P90D returns 93 combined MPG. Cars in the Large Cars class for the same model year average 27.4 MPG, which puts this car ahead of the class average by about 239%.
The most efficient car in the Large Cars class for the 2015 model year is the Tesla Model S AWD - 70D at 101 MPG. The bar chart below puts the Tesla Model S AWD - P90D alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2015 model year (across all classes) returns 24.6 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 2015 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 | $400 |
| Average driver, 15,000 miles per year | $800 |
| Heavy driver, 25,000 miles per year | $1,333 |

Specifications
The 2015 Tesla Model S AWD - P90D is a fully electric vehicle. It is powered by 164 (front) 350 (rear) (90 kw-hr battery pack). The EPA rates its driving range at 253 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 2015 Tesla Model S AWD - P90D
Quick answers to the questions people most often search for when looking up the 2015 Tesla Model S AWD - P90D.
-
Is the 2015 Tesla Model S AWD - P90D fuel efficient?
Yes. The 2015 Tesla Model S AWD - P90D returns 93 combined MPG, which beats the average car in the Large Cars class for the same model year by about 239%. -
What MPG does the 2015 Tesla Model S AWD - P90D get?
The EPA rates the 2015 Tesla Model S AWD - P90D at 93 combined MPG, 89 MPG in city driving, and 98 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 2015 Tesla Model S AWD - P90D per year?
The EPA estimates an annual fuel cost of $800 for the 2015 Tesla Model S AWD - P90D. 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 2015 Tesla Model S AWD - P90D use gasoline?
No. The 2015 Tesla Model S AWD - P90D 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 AWD - P90D become more fuel efficient over time?
Combined MPG has stayed close to flat across the run. Both the earliest (2015 Tesla Model S AWD - P90D, 93 MPG) and most recent (2017 Tesla Model S AWD - P90D, 95 MPG) versions sit in the same range. -
How much CO₂ does the 2015 Tesla Model S AWD - P90D emit?
The 2015 Tesla Model S AWD - P90D 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 2015 Tesla Model S AWD - P90D?
City driving returns 89 MPG and highway driving returns 98 MPG, a gap of 9 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise. -
What motor does the 2015 Tesla Model S AWD - P90D use?
The 2015 Tesla Model S AWD - P90D uses 164 (front) 350 (rear) (90 kW-hr battery pack). 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 2015 Tesla Model S AWD - P90D have?
The 2015 Tesla Model S AWD - P90D 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 2015 Tesla Model S AWD - P90D compare to the best car in its class?
The most efficient car in the Large Cars class for the 2015 model year is the Tesla Model S AWD - 70D at 101 combined MPG. The Tesla Model S AWD - P90D returns 93 MPG, a gap of 8 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
