134 MPG combined. The 2021 Tesla Model 3 Long Range AWD achieves this fuel economy, and it’s a key figure reflecting the car’s character. It represents a major change in how we view performance and efficiency, blending rapid acceleration with very low fuel costs, which appeals to tech-savvy buyers who appreciate a sporty driving experience. This is a suitable daily driver for those focused on the future, who value innovation and lower running costs instead of traditional luxury badging.

City and highway performance

That combined figure breaks down into 141 MPG in the city and 127 MPG on the highway. Electric vehicles often achieve higher MPG in the city due to regenerative braking, which recaptures energy during deceleration and returns it to the battery. The Model 3 is efficient in stop-and-go traffic, where gasoline-powered cars typically have the worst fuel economy. The highway number, while slightly lower, is still very good, proving the Model 3’s sleek aerodynamics and efficient motor design allow it to maintain good efficiency even at higher speeds. This performance is important for buyers who split their time between city commutes and longer road trips, providing a fuel efficient way to travel.

Annual fuel cost

The EPA estimates an annual fuel cost of just $550 for the 2021 Tesla Model 3 Long Range AWD. This is based on driving 15,000 miles per year at the national average electricity price. The savings compared to a similar-sized gasoline vehicle can be significant, especially for high-mileage drivers, and is a major factor for those considering electric power. This predictable figure can provide peace of mind when comparing to traditional internal combustion vehicles, and helps to stabilize the driving budget.

Real-world expectations

While the official EPA numbers provide a good baseline, real-world efficiency can vary depending on driving habits, weather, and accessory use. Hard acceleration and frequent hard braking will deplete the battery faster. Extreme temperatures can also impact range, as the car uses energy to regulate battery temperature. Even under less-than-ideal conditions, however, the Model 3 Long Range AWD consistently delivers good efficiency, often exceeding expectations for drivers who prioritize smooth acceleration, regenerative braking, and preconditioning the cabin while plugged in.

How it compares

When compared to other vehicles in both the electric and non-electric segments, the 2021 Tesla Model 3 Long Range AWD stands out. A comparable gasoline-powered luxury sedan, such as the BMW 330i xDrive, achieves around 28 MPG combined. The Model 3 has significantly lower fuel costs, even with the potentially higher initial purchase price. Against alternatives like the Polestar 2 (78 MPG combined) or the Audi e-tron (78 MPG combined), the Model 3 is still a top performer in its class of mid-sized electric cars. The range and efficiency of the Model 3 are key advantages for buyers prioritizing long-distance travel and minimizing charging stops.

Tips to maximize efficiency

Optimize your charging routine. Charge your Model 3 during off-peak hours to take advantage of lower electricity rates whenever possible. Set a charging schedule within the Tesla app to ensure your vehicle is always ready when you need it, without topping off the battery when electricity prices are higher.

Use regenerative braking. Adjust the regenerative braking setting to the “Standard” setting to maximize energy recapture during deceleration. Practice anticipating traffic flow and lifting off the accelerator early to slow down, rather than relying solely on the brakes. This will not only extend your range but also reduce wear and tear on your brake pads.

Precondition the cabin. Before starting your drive, use the Tesla app to preheat or precool the cabin while the car is still plugged in. This will minimize the energy required to reach your desired temperature once you’re on the road, preserving your range. This is especially beneficial during extreme weather.

Monitor your driving. Keep an eye on the energy graph displayed on the center screen. It provides real-time feedback on your energy consumption. Strive for smooth acceleration and consistent speeds to minimize energy use and maximize efficiency. Avoid aggressive acceleration, especially from a standstill, as it can significantly impact efficiency.
