142 MPG combined for the 2021 Tesla Model 3 Standard Range Plus RWD isn’t just a number. It prioritizes near-zero running costs, embraces electric vehicle technology, and accepts certain compromises to drive what is arguably the most desirable entry-level EV on the market. This isn’t about pinching pennies at the pump, it’s about bypassing the pump altogether and plugging into the future.

City and highway performance

The EPA breaks down the Model 3’s efficiency further, awarding it 150 MPG in the city and 133 MPG on the highway. These figures reflect the vehicle’s regenerative braking system, which is most active in stop-and-go city driving, capturing kinetic energy and converting it back into battery charge. The slightly lower highway MPG is typical of EVs, as wind resistance becomes a greater factor at higher speeds and regenerative braking opportunities decrease. City dwellers will see exceptional economy. Those who spend more time cruising on the interstate will still be impressed.

Annual fuel cost

The Model 3’s low running costs are further highlighted by the EPA’s annual fuel cost estimate of just $550. This figure is based on driving 15,000 miles per year, using a combination of city and highway driving, and factoring in the national average electricity prices. While electricity prices can vary significantly depending on location and time of day, $550 is an incredibly low annual running cost compared to any gasoline-powered vehicle of similar size and performance. The Model 3’s ability to travel significant distances on a single charge minimizes the number of times it needs to be plugged in, which contributes to the low running costs.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary depending on several factors including driving style, weather conditions, and the use of accessories like air conditioning and heating. Aggressive acceleration, frequent hard braking, and sustained high speeds will reduce efficiency. Cold weather, which can decrease battery performance, will also have a negative impact. Even under less-than-ideal conditions, the Model 3 Standard Range Plus RWD should deliver exceptional energy efficiency, significantly outperforming comparable gasoline-powered vehicles. Owners who prioritize smooth acceleration, anticipate traffic flow, and pre-condition the cabin while plugged in can expect to achieve results that closely align with the EPA’s estimates.

How it compares

Compared to its gasoline-powered counterparts, the Model 3’s fuel economy is far better. For comparison, a BMW 330i achieves approximately 29 MPG combined, while the Audi A4 manages around 30 MPG. Even hybrid sedans like the Toyota Camry Hybrid, which boasts around 52 MPG combined, fall far short of the Model 3’s electric efficiency. Looking at other EVs, all Tesla fuel economy data points to Tesla leading the pack. The Nissan LEAF achieves approximately 111 MPG combined, while the Chevrolet Bolt EV gets around 120 MPG. For those interested in MODEL MPG across all years, the Model 3 consistently demonstrates superior electric efficiency. This huge difference is a primary purchase driver for many buyers. They’re willing to deal with charging logistics for the sheer savings and lower fuel costs.

Tips to maximize efficiency

Engage ‘Chill’ mode to soften acceleration and reduce energy consumption. The Model 3 offers selectable driving modes, and ‘Chill’ prioritizes efficiency over outright performance. While it impacts the car’s spirited acceleration, it significantly reduces the amount of energy demanded from the battery, extending your range between charges.

Use regenerative braking to your advantage. Anticipating traffic flow and lifting off the accelerator early allows the regenerative braking system to recapture kinetic energy and replenish the battery. This not only extends your range but also reduces wear and tear on the physical brakes.

Pre-condition the cabin while plugged in. Heating or cooling the interior of the car while it’s connected to the charging station draws power from the grid rather than the battery, preserving your range when you’re on the road. This is particularly beneficial in extreme temperatures.

Maintain optimal tire pressure. Properly inflated tires reduce rolling resistance, which improves energy efficiency. Check your tire pressure regularly and ensure it matches the recommended specifications for your Model 3.

Minimize unnecessary weight. Carrying excessive cargo in your car increases the amount of energy required to accelerate and maintain speed. Remove any unnecessary items from your trunk and passenger compartment to improve efficiency.
