108 combined MPG is a surprising number, especially when you realize that’s what the 2018 Kia Soul Electric achieves. This isn’t a gas-guzzling SUV or even a hybrid trying to gain a few extra miles. It is a fully electric urban vehicle built for short commutes and city errands. The Soul EV appeals to a specific buyer: someone who wants low running costs, zero tailpipe emissions, and doesn’t require massive range or a luxurious interior. They understand its limitations and accept them. The benefit is an almost guilt-free driving experience that’s more affordable than many think.

City and highway performance

The EPA breaks down the Soul Electric’s fuel economy, demonstrating how efficiently it performs in its intended environment. The city MPG figure increases to 124, showing the regenerative braking system’s capability to recapture energy during frequent stops and starts. This is where the Soul Electric shines, offering exceptional efficiency in dense urban areas. On the highway, the MPG decreases to 93. This decrease is typical for electric vehicles because they don’t have the benefit of regenerative braking at higher speeds, and aerodynamic drag becomes significant. However, 93 MPG is still impressive, exceeding what any gasoline-powered vehicle can do on the open road.

Annual fuel cost

The most important aspect of the 2018 Kia Soul Electric for many owners is its low running cost. The EPA estimates the annual fuel cost at $700. This calculation is based on driving 15,000 miles per year, using the national average electricity price. Remember that electricity rates vary, so your actual cost may differ depending on your location’s utility rates. Even with higher electricity prices, the Soul EV typically costs less to “fuel” than a comparable gasoline-powered car. It’s a factor in its appeal to budget-conscious buyers who want to minimize transportation expenses. The annual fuel cost also depends on access to free charging stations in the community.

Real-world expectations

While the EPA provides MPG estimates, it’s essential to understand that driving conditions can affect your actual fuel economy. Factors such as driving style, temperature, and terrain can influence the Soul Electric’s range and efficiency. Aggressive acceleration, high speeds, and using the air conditioning or heater can reduce range. Gentle acceleration, moderate speeds, and preconditioning the cabin while plugged in can maximize range. Cold weather can greatly impact battery performance, reducing range by 20-40%. The EPA numbers are a benchmark, but expect variation based on your driving habits and environment. For more information on all Kia fuel economy data, consult our resource page.

How it compares

The 2018 Kia Soul Electric competes with other small electric vehicles of its time. The Nissan LEAF, for instance, offered around 124 City / 99 Highway MPGe in its standard trim, while the BMW i3 boasted 177 City / 151 Highway MPGe. While the BMW had a higher price, its MPGe exceeds other vehicles in its class. The Chevy Bolt was another competitor, estimated at 128 City / 110 Highway MPGe. The Soul Electric’s target buyer wants practicality and affordability over range or luxury. They’re willing to sacrifice some range in city driving for a lower price and the boxy styling that makes the Soul unique. Knowing SOUL MPG across all years can offer further context for value comparison.

Tips to maximize efficiency

Preconditioning the cabin while the Soul Electric is plugged in maximizes range, especially in cold weather. This allows you to heat or cool the interior using grid power, rather than draining the battery during your drive.

Gentle acceleration and braking are important for maximizing efficiency. Avoid sudden bursts of speed or hard braking, as they consume more energy. Using the regenerative braking system effectively recaptures energy and extends your range.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, which can improve fuel economy. Check your tire pressure regularly and inflate them to the recommended level.

Minimize the use of air conditioning and heating, as these can impact range. If possible, use the seat heaters or heated steering wheel instead of the cabin heater, as they consume less energy.

Plan your routes strategically. Avoid congested areas and steep inclines, as these conditions can reduce fuel economy. Use route planning apps that factor in elevation and traffic conditions to optimize your driving for maximum range.
