The 2018 Tesla Model S 75kWh gets 98 MPG combined, and redefines expectations for a luxury sedan. This rating represents how far you can travel on the equivalent of one gallon of gasoline. This metric is a critical component in the Model S’s appeal, particularly for tech-forward early adopters who prioritize lower fuel costs and cutting-edge performance.

City and highway performance

The 2018 Tesla Model S 75kWh achieves an EPA-estimated 97 MPG in the city and 100 MPG on the highway. These figures highlight one of the key advantages of electric powertrains: consistent efficiency regardless of driving conditions. Unlike gasoline engines, which can suffer significant fuel economy drops in stop-and-go traffic, electric motors thrive in city environments, using regenerative braking to recapture energy. The highway MPG, slightly higher than the city, demonstrates the Model S’s ability to maintain optimal efficiency even at higher speeds, which is thanks to its aerodynamic design and efficient powertrain. These strong numbers are essential for buyers who use their Model S for both daily commutes and long-distance trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Tesla Model S 75kWh to be $750. This figure is calculated based on 15,000 miles of driving per year, using national average electricity prices. For Model S owners, this translates to substantial savings compared to traditional gasoline-powered luxury sedans. However, the actual cost can vary significantly depending on individual driving habits, electricity rates, and charging patterns, especially the amount of expensive Supercharger use. Those who primarily charge at home during off-peak hours can often reduce their energy costs far below even this impressive EPA estimate.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world energy consumption can fluctuate. Factors such as driving style, climate control usage, and ambient temperature can all impact range and efficiency. Aggressive acceleration, high speeds, and extensive use of air conditioning or heating will reduce the range. Owners in colder climates might see a more pronounced decrease in efficiency due to the energy required to warm the battery pack and cabin. However, even with these variables, the 2018 Tesla Model S 75kWh consistently delivers impressive efficiency, making it a standout performer in the luxury EV segment. Be sure to check MODEL MPG across all years.

How it compares

Compared to other luxury vehicles, the 2018 Tesla Model S 75kWh’s efficiency is in a different league. A comparable gasoline-powered sedan, such as the BMW 530i, achieves around 27 MPG combined. Even hybrid models like the Lexus ES 300h, which boasts approximately 44 MPG combined, fall far short of the Model S’s electric efficiency. The Audi e-tron of the same year achieves just 74 MPGe combined. The Model S buyer is often comparing with other EVs like the Chevrolet Bolt (119 MPGe combined) and not gasoline cars. These efficiency advantages are critical for buyers seeking to minimize their environmental impact and reduce their running costs, which is a key reason many choose Tesla over other premium brands.

Tips to maximize efficiency

Use regenerative braking to the fullest. Tesla’s regenerative braking system can recapture a significant amount of energy, especially in city driving. Adjust the regenerative braking setting to your preference (Standard or Low) to optimize energy recovery and extend your range.

Precondition the cabin while the car is plugged in. Heating or cooling the cabin while the vehicle is connected to a charger uses grid power, preserving battery range for driving. This is particularly beneficial during extreme weather conditions.

Maintain optimal tire pressure. Properly inflated tires reduce rolling resistance, improving overall efficiency. Check your tire pressure regularly and inflate to the recommended level indicated on the doorjamb sticker.

Minimize aggressive driving. Rapid acceleration and high speeds consume significantly more energy. Smooth, consistent driving habits will maximize your Model S’s range. Use “Chill” mode when possible, and avoid frequent, hard starts from a stop.

Plan your trips strategically. Use Tesla’s navigation system to optimize your route and identify charging locations along the way. Pre-planning can reduce range anxiety and ensure a smooth, efficient journey.
