The 2017 Tesla Model S AWD P100D achieves 98 MPGe combined. This shows how electric vehicles have changed performance motoring. It’s a high-performance sedan with fast acceleration, a luxurious interior, and advanced technology. Buyers of this Model S aren’t primarily interested in fuel savings. They want performance, technological innovation, and lower fuel costs. They know that the cost to charge the car will be much less than fuel for a similar gas-powered car.

City and highway performance

The EPA estimates for the P100D are strong, with 92 MPGe in the city and 105 MPGe on the highway. This difference shows the electric motor’s efficiency at constant speeds, when regenerative braking isn’t cycling energy back into the battery. The Model S is excellent on the open road, making long trips guilt-free when it comes to energy consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Tesla Model S AWD P100D at $800. This is based on 15,000 miles per year, using the national average electricity costs at the time of testing. This is impressive, considering the P100D’s performance. Drivers who travel less will likely spend less, and those with free charging, such as at work, could have almost no fuel costs.

Real-world expectations

The EPA estimates provide helpful information, but real-world MPGe can change based on driving style, temperature, and climate control use. Quick acceleration reduces efficiency, as does constant high-speed driving. Cold temperatures also affect battery performance, possibly decreasing range and MPGe. But with careful driving, meeting or exceeding the EPA estimates is possible.

How it compares

The P100D is in a unique performance category. The Porsche Taycan Turbo S gets about 69 MPGe combined, meaning that even high-end electric cars aren’t as efficient. A similar gas-powered car, like a BMW M5, might only get about 17 MPG combined. Even hybrid luxury sedans, like the Lexus ES 300h with about 44 MPG combined, don’t come close to the Tesla’s efficiency. This comparison highlights the P100D’s unique advantage: delivering supercar performance with impressive fuel economy. Buyers seeking all Tesla fuel economy data will find that the Model S P100D is regularly among the most efficient in the lineup.

Tips to maximize efficiency

Use regenerative braking. Tesla’s regenerative braking system captures kinetic energy and returns it to the battery very well. Set the regen setting to “Standard” to recover as much energy as possible when slowing down. This simple change can extend your range.

Precondition the battery. In cold weather, precondition the battery using the Tesla app before driving. This warms the battery to its best operating temperature, improving range and performance. Similarly, in very hot weather, precooling the cabin and battery can help manage energy use.

Optimize tire pressure. Check and keep the tires at the correct pressure. Low tires increase rolling resistance, reducing efficiency. The correct pressure is usually on a sticker on the driver’s side door.

Reduce aerodynamic drag. At highway speeds, aerodynamic drag is a big factor. Don’t use roof racks or carriers unless needed because they increase wind resistance and reduce efficiency. Smooth and steady driving helps a lot.

Pay attention to model MPG across all years if you’re considering used models. The 2017 P100D is great, but newer models may have improvements in efficiency and battery technology.
