103 MPG combined is impressive. This is the fuel economy of the 2018 Tesla Model S 75D. This isn’t a compact hybrid trying to save fuel. It’s a sleek, powerful sedan delivering performance and zero-emission driving. Owners accept this fuel economy because it shows commitment to sustainable driving and rejecting traditional gasoline vehicles.

City and highway performance

The EPA estimates for the 2018 Model S 75D are 102 MPG in the city and 105 MPG on the highway. The slight edge on the highway reflects the regenerative braking system’s strength in stop-and-go city traffic. The Model S captures kinetic energy during deceleration, converting it back into electricity to recharge the battery. This makes city driving efficient, while on the highway, consistent speeds result in slightly lower regeneration but still excellent overall efficiency.

Annual fuel cost

The EPA estimates an annual fuel cost of $750 for the 2018 Tesla Model S 75D. This calculation assumes 15,000 miles of driving per year, split between city and highway miles, and uses the national average electricity prices. Your actual costs may vary depending on your electricity rates, driving habits, and how often you charge at home versus at public charging stations.

Real-world expectations

While the EPA provides a standardized metric, real-world fuel economy for any vehicle, including the Model S 75D, can fluctuate. Factors like driving style, ambient temperature, tire pressure, and cargo weight impact range. Aggressive acceleration and frequent use of “Ludicrous” mode drain the battery faster. Cold weather can reduce battery performance and range. So, adopt efficient driving habits and properly maintain your vehicle to achieve the best results. Keep track of your electricity costs per mile to understand your actual savings.

How it compares

The Model S operates in a unique space. While other electric vehicles exist, few offer the same performance, range, and luxury. For example, the 2018 Chevrolet Bolt offers a good range at a lower price, but its smaller size and less luxurious interior create a different ownership experience. The Bolt achieves an EPA-estimated 128 combined MPGe. The BMW i3, another EV option, offers quirky styling and nimble handling, but its range is significantly less than the Model S, and achieves 113 combined MPGe. Even within Tesla’s lineup, comparing the Model S to a Model 3 reveals trade-offs. The Long Range Model 3, rated at 131 combined MPGe, provides similar range to the 75D, but in a smaller, less expensive package. For those prioritizing space, performance and range, the Model S remains a strong choice. Compare all Tesla fuel economy data to see how range and efficiency have changed across the model lineup.

Tips to maximize efficiency

Use the Model S’s regenerative braking system. Anticipate traffic flow and ease off the accelerator early to maximize energy recapture. This extends your range and reduces wear on your brake pads.

Precondition your battery before driving, especially in cold weather. Use the Tesla app to remotely warm the battery and cabin while the car is plugged in. This improves efficiency and range during chilly drives.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces efficiency. Check your tire pressure regularly and inflate them to the recommended levels, usually found on a sticker inside the driver’s side doorjamb.

Reduce aerodynamic drag. Remove unnecessary roof racks or cargo carriers when they’re not in use. Small changes in aerodynamics can impact efficiency, particularly at higher speeds. Also, don’t spend more time than necessary with the windows open at highway speeds.

Consider using the Chill driving mode. While Ludicrous mode is fun, it consumes more energy. For everyday commuting, Chill mode provides ample acceleration while maximizing efficiency. Explore MODEL MPG across all years.
