108 MPG combined means the 2020 Nissan LEAF (62 kW-hr battery pack) offers exceptional fuel economy, a key reason why many drivers choose this EV. This isn’t a performance machine, nor is it trying to be. This LEAF is designed to be an affordable, practical, and efficient hatchback for those prioritizing low running costs and less gas. Buyers accept its limitations, relatively short range and modest performance, because of this inherent efficiency.

City and highway performance

The EPA breaks down the LEAF’s efficiency further, revealing an impressive 118 MPG in the city and 97 MPG on the highway. This difference showcases the LEAF’s strength in stop-and-go traffic, where regenerative braking captures energy to replenish the battery. Unlike gasoline cars, electric vehicles thrive in city driving and the LEAF is no exception. While the highway MPG is still excellent, it’s lower due to the increased energy required to overcome aerodynamic drag at higher speeds. This means owners will see the greatest fuel economy savings in urban or suburban settings.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Nissan LEAF (62 kW-hr battery) at $700. This figure is based on driving 15,000 miles per year and using the national average electricity prices. Keep in mind that your actual fuel cost may vary depending on your local electricity rates, driving habits, and the climate you live in. Charging at home during off-peak hours can significantly lower your costs, while relying on public charging stations during peak times will do the opposite. However, even with less-than-ideal charging practices, the LEAF’s dramatically lower fuel costs offer a significant advantage over gasoline-powered vehicles. Considering there is drastically less maintenance, over time, that brings even greater savings!

Real-world expectations

While the EPA figures are a good benchmark, real-world fuel economy can vary. Factors such as driving style, outside temperature, and the use of accessories like air conditioning and heating can all affect efficiency. Aggressive acceleration and high speeds will deplete the battery faster, while gentle driving and pre-conditioning the cabin while the car is plugged in can help maximize range. Many LEAF owners report achieving similar or even better MPGe than the EPA estimates, particularly in moderate climates and with conscious driving habits. The regenerative braking system is hugely beneficial, but drivers need to adjust their driving habits to make the most of the energy recapture.

How it compares

Compared to other EVs in its class, the 2020 Nissan LEAF (62 kW-hr) holds its own in terms of efficiency. The Hyundai Kona Electric, for example, delivers 120 MPGe combined, a slight edge over the LEAF. The Chevrolet Bolt offers 118 MPGe combined. However, the LEAF typically comes in at a lower price point, while still offering a decent range and respectable fuel economy. These are the factors that weigh heavily on the LEAF buyer. They are prepared to give up that extra range, or shaving a fraction from the 0-60 time, in return for getting a better overall deal.

Tips to maximize efficiency

Precondition the cabin before you drive, especially in extreme temperatures. Heating and cooling the car while it’s plugged in draws power from the grid rather than the battery, preserving your range. Start this process via the NissanConnect app while the LEAF is still charging, and you’ll be sitting pretty when it comes time to hit the road.

Use the “Eco” mode, which reduces throttle response and limits energy consumption. This mode helps to smooth out acceleration and minimize energy waste, allowing you to extract more miles from each charge. Eco mode can feel lazy at first, but try to get used to it!

Anticipate traffic flow and coast whenever possible to maximize regenerative braking. By lifting off the accelerator early and allowing the car to slow down naturally, you can capture kinetic energy and replenish the battery. It takes a little getting used to but becomes second nature.

Keep your tires properly inflated according to the manufacturer’s specifications. Underinflated tires increase rolling resistance and reduce fuel efficiency. Check your tire pressure regularly to ensure optimal performance and safety. This is good practice for ANY car, but really helps boost efficiency on an EV.

Consider browsing LEAF MPG across all years if you are considering an older model. Also, check all Nissan fuel economy data to see how the figures vary across the entire model line versus other manufacturers.
