The 2017 Tesla Model S AWD – 100D gets a combined EPA rating of 102 MPGe, making it a very efficient car. For owners of this all-wheel-drive luxury sedan, 102 MPGe means not needing to visit gas stations, highlighting Tesla’s commitment to zero-emission driving without sacrificing performance or range.

City and highway performance

The Model S 100D’s efficiency has specific numbers. The EPA rates it at 101 MPGe in the city and 102 MPGe on the highway. This close range shows the electric powertrain’s consistent efficiency no matter the driving environment. Unlike gasoline cars where stop-and-go driving hurts fuel economy, the Tesla benefits from regenerative braking in urban settings. It recovers energy and reduces energy waste. On the highway, the slightly higher rating shows the steady efficiency of the electric motors when cruising at consistent speeds.

Annual fuel cost

The EPA estimates an annual fuel cost of $750 for the 2017 Tesla Model S AWD – 100D. This is based on driving 15,000 miles per year and using national average electricity prices. This is a great number that shows the big savings from not using gasoline, especially for those who drive a lot. Keep in mind that actual costs change based on driving habits, local electricity rates, and charging choices (home versus public). Even with changes, the consistent lack of gasoline means lower annual energy expenses.

Real-world expectations

The EPA ratings are a guide, but real-world range and efficiency of the Model S 100D depends on different things. Hard acceleration drains the battery faster, while gentle acceleration and maximizing regenerative braking can extend range. Cold weather also matters, it reduces battery performance, affecting efficiency and range. Also, using the climate control (heating or air conditioning) takes more power. Most owners find the EPA numbers to be a good guide, but changing driving style to be more efficient can produce better results.

How it compares

The 2017 Tesla Model S AWD – 100D is unique compared to other luxury sedans. The BMW 740i xDrive, gets a combined 22 MPG, and the Mercedes-Benz S560 4MATIC gets 21 MPG. Even hybrid luxury sedans like the Lexus LS 500h only reach around 29 MPG combined. These numbers show the Tesla’s efficiency advantage. For buyers wanting fewer emissions and lower fuel costs, the Model S 100D’s efficiency is a big advantage over gasoline or hybrid cars.

Tips to maximize efficiency

Set regenerative braking higher in the Tesla’s settings. A higher setting allows for stronger deceleration, which sends more energy back to the battery. Watch traffic and plan your driving. This reduces hard braking and acceleration, saving energy.

Warm up or cool the cabin while the car is plugged in. This heats or cools the inside drawing power from the grid and not the battery, saving range, during extreme temperatures.

Check tire pressure regularly. Tires with the right amount of air reduce rolling resistance, improving efficiency. Even a little PSI difference makes a difference on an EV.

Remove extra items from the car. More weight needs more energy to move, which hurts efficiency. Remove unnecessary items from the trunk and cabin to reduce energy use.

Use the Tesla’s range mode. It limits top speed and changes climate control for better efficiency. Even though it changes performance a little, it can add a lot of range, especially on long trips.
