Earning an EPA-estimated 89 MPGe combined, the 2016 Tesla Model S (85 kW-hr battery pack) changes what it means to drive an efficient luxury car. This isn’t about squeezing every last drop from a gallon of gasoline; it blends high performance with zero tailpipe emissions in a package that redefines the modern automobile.

City and highway performance

The official figures for the 2016 Model S 85 are consistent across different driving conditions. The EPA rates it at 88 MPGe in the city and 90 MPGe on the highway. This near-identical performance shows the electric powertrain’s efficiency. Unlike internal combustion engines that often perform poorly in stop-and-go traffic, the electric motor’s regenerative braking system recovers energy in the city, contributing to that impressive MPGe figure. On the highway, the Model S maintains its efficiency, proving that electric vehicles are not just for short commutes, but for longer journeys, too.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 Tesla Model S 85 is $850. This figure is based on driving 15,000 miles per year, with a set percentage of city versus highway miles. The EPA also uses the national average electricity price to determine this estimate. Your actual “fuel” cost will depend on your driving habits, local electricity rates, and how much you rely on public charging, which is often more expensive than charging at home.

Real-world expectations

While the EPA numbers provide a useful benchmark, real-world MPGe can vary. Aggressive acceleration, frequent use of climate control, and cold weather can all reduce the Model S’s efficiency and driving range.
Drivers who want to maximize range will learn to modulate their acceleration, pre-condition the cabin while plugged in, and use the car’s energy consumption display to monitor their driving.
The advantage of an electric vehicle is that you can change your personal “fuel economy” by refining your driving style, something less impactful in a gasoline-powered car. Be sure to check MODEL MPG across all years to compare figures from other Tesla models.

How it compares

The 2016 Model S 85 is unique, easily surpassing other luxury sedans in terms of fuel economy.
Consider the BMW 740i, which achieves approximately 25 MPG combined, or the Mercedes-Benz S550, which manages around 20 MPG.
Even hybrid luxury cars like the Lexus LS 600h can’t match the Model S’s zero-emission efficiency, with a combined MPG of about 20. The Model S changes the entire game, appealing to buyers who value sustainability, technology, and performance. Those interested in other Tesla offerings can find all Tesla fuel economy data and evaluate that model in relation to the Model S.

Tips to Maximize Efficiency

One of the simplest ways to increase your Model S’s efficiency is to use regenerative braking to its fullest potential. By easing off the accelerator and allowing the car to slow down naturally, you’ll recover energy and maximize your range. Learn the one-pedal driving mode for optimal effect.

Pre-conditioning the cabin while the car is plugged in can reduce energy consumption, especially in extreme temperatures. Heating or cooling the interior while connected to the grid avoids draining the battery and helps maintain optimal range for your trip.

Tire pressure is important for efficiency. Keep your tires inflated to the recommended pressure, as indicated on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces fuel economy and affects handling.

Reduce aerodynamic drag by minimizing the use of roof racks or cargo carriers when not needed. These accessories create additional drag, which can negatively impact fuel efficiency, particularly at highway speeds.
