The 2017 Mitsubishi i-MiEV gets 112 MPGe combined, placing it among the most efficient vehicles ever sold in the United States. This extraordinary figure comes with some limitations. The i-MiEV isn’t designed for long road trips, luxurious accommodations, or fast performance. It’s designed for very efficient urban transportation. Its mission is tightly focused, and its appeal is limited. But for those whose needs match its capabilities, the i-MiEV delivers unmatched economy.

City and highway performance

The EPA rates the 2017 i-MiEV at 121 MPGe in the city and 102 MPGe on the highway. This difference shows the i-MiEV’s ideal use. Its electric motor operates at maximum efficiency in stop-and-go traffic, using regenerative braking to recapture energy while slowing down. On the open road, where wind resistance is a bigger factor, the i-MiEV’s efficiency drops, but it still achieves a triple-digit rating. These figures mean real savings for drivers who mainly commute in cities.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Mitsubishi i-MiEV at just $700. This is based on driving 15,000 miles per year and using national average electricity prices. While electricity rates change across the country, this estimate helps compare the i-MiEV’s running costs to those of regular gasoline-powered vehicles. Many gasoline vehicles with similar interior space cost $2,000 or even $3,000 per year to fuel. The i-MiEV offers a remarkable drop in energy costs.

Real-world expectations

The EPA’s figures offer a reference point, but actual MPGe can change based on driving habits, weather, and terrain. Hard acceleration, frequent climate control, and hilly roads can all hurt efficiency. On the other hand, gentle acceleration, good regenerative braking, and pre-heating or cooling the cabin while plugged in can help maximize range and MPGe. Owners say that meeting or beating the EPA’s estimates is possible with careful driving, as shown in the I MIEV MPG across all years.

How it compares

The i-MiEV’s fuel economy is very different from gasoline-powered cars. A similar-sized gasoline car, like the Mitsubishi Mirage, gets around 39 MPG combined. Even efficient hybrids, such as the Toyota Prius (52 MPG combined) or the Honda Insight (55 MPG combined), can’t match the i-MiEV’s electric efficiency. The i-MiEV’s low purchase price and available federal and state tax incentives back when it was new helped some buyers see it as a good, though unusual, choice for budget-conscious and eco-minded city residents. Buyers wanting the lowest running costs often ignore the car’s limited range and basic interior, focusing on its unmatched efficiency. For a wider brand view, consider all Mitsubishi fuel economy data.

Tips to maximize efficiency

Use regenerative braking. The i-MiEV’s regenerative braking system captures energy while slowing down and turns it back into electricity, extending the car’s range. Lift off the accelerator early when stopping or slowing down, letting the regenerative braking work.

Pre-heat or cool the cabin while plugged in. Heating or cooling the i-MiEV’s cabin uses energy. To use less of your range, pre-heat or cool the cabin while the car is plugged in. This lets you start driving with a comfortable temperature without using battery power.

Drive smoothly and avoid fast acceleration. Fast acceleration drains the battery quickly. Drive smoothly and keep a consistent speed to maximize efficiency. Watch traffic and avoid sudden bursts of speed.

Check your tire pressure often. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure at least once a month and inflate them to the recommended pressure on the doorjamb sticker. This helps your i-MiEV’s efficiency.

Use fewer accessories. Running the air conditioning, heater, and other electrical items uses battery power. Use these accessories less to extend your range. If possible, use outside air or dress for the weather to use the climate control less.
