98 MPG combined is an astonishing figure, especially when referring to a large, luxurious, and quick sedan like the 2017 Tesla Model S with the 75 kW-hr battery pack. This isn’t a hybrid sipping fuel to achieve that number; it’s a purely electric vehicle providing supercar-rivaling acceleration with running costs that dramatically undercut anything burning gasoline.

City and highway performance

The EPA’s city and highway estimates for the 2017 Tesla Model S (75 kW-hr) are remarkably consistent: 97 MPG in the city and 100 MPG on the highway. This close spread shows the efficiency of the electric powertrain across various driving conditions. Unlike gasoline engines, which often suffer significant drops in efficiency in stop-and-go city driving, the Model S uses regenerative braking to recoup energy lost during deceleration, boosting its city MPG figure. The highway number also benefits from Tesla’s focus on aerodynamics, allowing it to cruise efficiently even at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Tesla Model S (75 kW-hr) at a mere $750. This figure is calculated based on 15,000 miles of driving per year, using the national average electricity prices. The Model S’s ability to travel long distances on a single charge, combined with the lower cost per mile of electricity compared to gasoline, translates into substantial savings for owners. Of course, this also depends on your location as electric rates vary greatly across North America and the world.

Real-world expectations

While EPA ratings provide a good benchmark, real-world range and efficiency figures can vary based on driving style, weather conditions, and accessories used. Aggressive acceleration, high speeds, and frequent use of climate control can all reduce range. However, even with these factors considered, most drivers will still see significantly lower “fuel” costs than they would with a comparable gasoline-powered luxury sedan. Many owners also take advantage of off-peak charging rates to further reduce their electricity expenses.

How it compares

Compared to gasoline-powered competitors, the 2017 Tesla Model S (75 kW-hr) presents a strong economic case. A similarly sized and performing sedan like the BMW 540i xDrive, for example, achieves around 23 MPG combined, costing more than triple in fuel annually. Even hybrid luxury sedans like the Lexus ES 300h, with its 44 MPG combined, can’t match the Tesla’s low running costs. A Tesla buyer isn’t just looking for luxury or performance; they are also prioritizing lower fuel costs. Check all Tesla fuel economy data and MODEL MPG across all years.

Tips to maximize efficiency

Gentle acceleration and braking are key to maximizing the range of your 2017 Tesla Model S. Avoid sudden bursts of speed and anticipate traffic conditions to allow for smooth deceleration, maximizing the regenerative braking effect. The more you use one-pedal driving, the better efficiency you’ll enjoy.

Preconditioning the cabin while the car is still plugged in can significantly reduce energy consumption while driving. Use the Tesla app to heat or cool the interior to your desired temperature while the car is charging, minimizing the drain on the battery once you hit the road. This is important in climates with extreme heat or cold.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which reduces efficiency and range. Check your tire pressure regularly and maintain it at the recommended level for optimal performance. Consider a low-rolling resistance tire when it is time to replace the stock version.

Minimize the use of energy-intensive accessories. While features like heated seats and climate control are convenient, they can consume significant energy. Use them sparingly, especially on shorter trips, to conserve battery power. Also keep in mind that driving at high speeds increases energy consumption due to air resistance. Sticking to moderate speeds on the highway will help extend your range.
