Fuel economy at a glance

These are the EPA's official ratings for the 2018 Tesla Model X 75D. 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).

How the 2018 Tesla Model X 75D compares

The 2018 Tesla Model X 75D returns 93 combined MPG. Cars in the Standard Sport Utility Vehicle 4WD class for the same model year average 21 MPG, which puts this car ahead of the class average by about 343%.

Within the Standard Sport Utility Vehicle 4WD class for the 2018 model year, the Tesla Model X 75D is the leader. No other car in the same class beat its 93 MPG rating. The bar chart below shows it alongside the class average and the average new car for some additional context.

For broader context, the average new car of the 2018 model year (across all classes) returns 25.6 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 2018 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

Compare against other Standard Sport Utility Vehicle 4WD for 2018

If you are cross-shopping the 2018 Tesla Model X 75D, the most useful comparison is against the other cars in the Standard Sport Utility Vehicle 4WD class for the same model year. The list below shows the highest-MPG peers, ranked from most to least efficient. Click any of them to open its full page.

Specifications

The 2018 Tesla Model X 75D is a fully electric vehicle. It is powered by 193 (front) 193 (rear) (75 kw-hr battery pack). The EPA rates its driving range at 238 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 2018 Tesla Model X 75D

Quick answers to the questions people most often search for when looking up the 2018 Tesla Model X 75D.

  • Is the 2018 Tesla Model X 75D fuel efficient?
    Yes. The 2018 Tesla Model X 75D returns 93 combined MPG, which beats the average car in the Standard Sport Utility Vehicle 4WD class for the same model year by about 343%.
  • What MPG does the 2018 Tesla Model X 75D get?
    The EPA rates the 2018 Tesla Model X 75D at 93 combined MPG, 91 MPG in city driving, and 95 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 2018 Tesla Model X 75D per year?
    The EPA estimates an annual fuel cost of $800 for the 2018 Tesla Model X 75D. 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 2018 Tesla Model X 75D use gasoline?
    No. The 2018 Tesla Model X 75D 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.
  • How much CO₂ does the 2018 Tesla Model X 75D emit?
    The 2018 Tesla Model X 75D 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 2018 Tesla Model X 75D?
    City driving returns 91 MPG and highway driving returns 95 MPG, a gap of 4 MPG. The two figures are close enough that the car will hold its rated efficiency well across most driving patterns.
  • What motor does the 2018 Tesla Model X 75D use?
    The 2018 Tesla Model X 75D uses 193 (front) 193 (rear) (75 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 2018 Tesla Model X 75D have?
    The 2018 Tesla Model X 75D 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.
  • Is the 2018 Tesla Model X 75D the most efficient car in its class?
    Yes. Among cars in the Standard Sport Utility Vehicle 4WD class for the 2018 model year, the Tesla Model X 75D returns the highest combined MPG at 93 MPG. No other car in the same class beats that figure.
  • What is the EV range of the 2018 Tesla Model X 75D?
    The EPA rates the 2018 Tesla Model X 75D for 238 miles of electric driving range on a full charge. That covers most daily commutes and weekend trips without needing a top-up, but plan ahead for longer drives.
