103 MPG combined is an extraordinary figure. It’s even more extraordinary when you realize that it belongs to the 2019 Tesla Model S 75D. This isn’t just a compact hatchback or a hybrid designed solely for maximizing efficiency, it’s a large, luxurious, and supremely quick sedan. The 75D designation means all-wheel drive and a 75 kWh battery pack, offering a blend of range, performance, and exceptional fuel economy.

City and highway performance

The EPA rates the 2019 Tesla Model S 75D at 102 MPG in the city and 105 MPG on the highway. These figures reflect the advantages of electric powertrains. Stop-and-go city driving, which often penalizes gasoline cars, allows the Model S to use regenerative braking, recouping energy and minimizing wasted momentum. On the highway, the Model S benefits from its aerodynamic design and efficient electric motor, maintaining impressive efficiency even at higher speeds. Of course, “MPG” is something of a misnomer here. What we’re really talking about is MPGe, or Miles Per Gallon equivalent, a metric used to compare the energy consumption of electric vehicles to that of cars that burn gasoline.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2019 Tesla Model S 75D is just $750. This calculation is based on 15,000 miles of driving per year, with a mix of city and highway use, and assumes the national average price of electricity. It is important to remember that this number is an estimate, and your actual costs will vary depending on your driving habits, where you live (electricity prices vary considerably by region), and how you charge your vehicle. Those who primarily charge at home during off-peak hours may see significantly lower costs, while those who rely on public charging stations, especially Tesla’s Supercharger network during peak demand, may find their expenses closer to or even exceeding the $750 estimate. However, even at the high end, the cost savings compared to a comparable gasoline-powered luxury sedan are substantial.

Real-world expectations

While the EPA’s ratings provide a standardized benchmark, real-world MPGe for the 2019 Tesla Model S 75D often varies. Factors such as driving style, ambient temperature, and terrain can all impact efficiency. Aggressive acceleration and high speeds will deplete the battery faster, and cold weather, in particular, can reduce range because the battery needs to expend energy to maintain its optimal temperature. However, even under less-than-ideal conditions, the Model S 75D consistently delivers impressive efficiency, far surpassing any gasoline-powered vehicle in its class. Owners who prioritize smooth acceleration, moderate speeds, and pre-conditioning the cabin while plugged in can often achieve figures that are very close to the EPA estimates.

How it compares

Compared to other luxury sedans, the 2019 Tesla Model S 75D resides in a completely different universe in terms of fuel economy. A Mercedes-Benz S-Class, for example, typically achieves around 22 MPG combined, while a BMW 7 Series hovers around 25 MPG. Even plug-in hybrid versions of these cars struggle to match the Tesla’s efficiency. The Porsche Panamera E-Hybrid, a plug-in hybrid, manages around 51 MPGe combined, although it will fall to the low 20s once it runs out of electric range. Looking beyond sedans, the Tesla Model X 75D, the SUV version of the Model S, achieves 93 MPGe combined. Choosing between these comes down to body style and cargo capacity. For anyone who values efficiency without sacrificing performance and luxury, all Tesla fuel economy data paints a clear picture: electric is the way to go.

Tips to maximize efficiency

One of the most effective ways to boost efficiency in the Model S 75D is to pre-condition the cabin while the vehicle is still plugged in. This allows you to heat or cool the interior without draining the battery’s range. Use the Tesla app to schedule pre-conditioning before your commute, ensuring a comfortable cabin and maximum range.

Regenerative braking is your friend. By setting it to “Standard,” you’ll maximize the amount of energy recaptured during deceleration. Anticipate stops and traffic to reduce reliance on the friction brakes. This not only improves efficiency, but also extends the life of your brake pads.

Driving at highway speeds impacts range noticeably. Maintaining a moderate speed, ideally around 65-70 mph, will significantly improve your MPGe. Use the in-car energy graph to monitor your consumption and adjust your speed accordingly.

Minimize unnecessary weight. Carrying extra cargo reduces efficiency in any vehicle, including the Model S. Remove items from the trunk that you don’t need on a regular basis to lighten the load and improve your MPGe. Consider the MODEL MPG across all years if cargo requirements are non-negotiable.

Keep your tires properly inflated. Low tire pressure increases rolling resistance, which reduces efficiency. Check your tire pressure regularly and inflate them to the recommended level (found on the driver’s side doorjamb). This simple step can make a noticeable difference in your Model S 75D’s fuel economy.
