30 MPG combined for the 2025 Kia Soul with the 2.0L 4-cylinder engine makes it efficient, an accessible, urban-friendly car delivering maximum utility and personality without punishing the wallet at the pump. This is not a vehicle designed for hypermiling or breaking land speed records. Its mission is to be a quirky, spacious, and fun alternative in a sea of increasingly mundane compact crossovers and SUVs, all while offering the kind of fuel economy that makes daily commutes and weekend adventures affordable.

City and Highway Performance

The EPA rates the 2025 Kia Soul 2.0L 4-cylinder at 27 MPG in the city and 33 MPG on the highway. These figures are in line with what one expects from a modern, naturally aspirated 2.0-liter engine paired with a continuously variable transmission (CVT), which Kia refers to as an IVT (Intelligent Variable Transmission). The Soul excels in urban environments, not just in terms of maneuverability and parking ease, but also in its ability to save fuel. The CVT’s infinitely variable gear ratios mean the engine can always operate in its most efficient band, whether you are navigating stop-and-go traffic or accelerating onto a freeway ramp. On the open road, that 33 MPG highway rating provides a decent cruising range, making spontaneous road trips a less costly undertaking. While it will not ever feel like a rocket ship, the powertrain is smooth and responsive enough for the Soul’s intended purpose, prioritizing efficiency and comfortable shifts over outright performance.

Annual Fuel Cost

The EPA estimates the annual fuel cost for the 2025 Kia Soul 2.0L 4-cylinder to be $1,450. This figure is based on an average of 15,000 miles driven per year, split between city and highway driving, using national average fuel prices. For a vehicle with such a distinctive style and practical interior space, a fuel bill in this range is remarkably low and a significant selling point. It directly contributes to the Soul’s reputation as a budget-friendly and economically sensible choice. Drivers looking to minimize their ongoing vehicle expenses will find this annual fuel cost particularly appealing, especially when considering the recent fluctuations in fuel prices. This predictable and modest outlay for fuel is a core part of the Soul’s value.

Real-World Expectations

In real-world driving, owners of the 2025 Kia Soul will often find these EPA numbers to be quite achievable, sometimes even exceeded under favorable conditions. The vehicle’s lightweight and aerodynamic (for its boxy shape) design, combined with the efficient 2.0L engine and well-calibrated IVT, work together to deliver consistent performance at the pump. Factors like aggressive driving, heavy loads, frequent short trips in cold weather, or excessive use of accessories (like air conditioning) will naturally impact these figures. Conversely, a driver with a light foot, who anticipates traffic and uses cruise control on the highway, can comfortably hit or even surpass the 33 MPG highway rating. The Soul genuinely performs as expected, delivering solid economy for its class.

How It Compares

When placed against its closest rivals, the 2025 Kia Soul’s fuel economy holds its own, often besting or matching popular alternatives. Consider the Mitsubishi Outlander Sport ES with its 2.0L engine and CVT. That vehicle manages 26 MPG combined (24 city/30 highway), making the Soul’s 30 MPG combined a clear win. The larger and more powerful Kia Seltos LX AWD, often cross-shopped for its similar dimensions, gets 29 MPG combined (27 city/31 highway) from its 2.0L engine – impressive for an AWD vehicle, but still slightly behind the FWD Soul. The Nissan Kicks S, another strong contender in the subcompact crossover segment, achieves a very competitive 33 MPG combined (31 city/36 highway) from its smaller 1.6L engine. If absolute highest MPG is the sole priority, the Kicks wins, but the Soul offers more expressive styling and often more passenger/cargo volume. The Soul’s 30 MPG combined positions it as a very strong contender, offering a blend of practicality, style, and efficiency without resorting to a significantly smaller engine or hybrid technology.

Tips to Maximize Efficiency

Maintaining proper tire pressure is one of the easiest and most effective ways to ensure your Soul achieves its optimal fuel economy. Check your owner’s manual for the recommended PSI and make sure to check pressures monthly, as underinflated tires increase rolling resistance and force the engine to work harder.

Smooth acceleration and braking significantly impact the 2.0L engine’s efficiency. Avoid rapid starts and sudden stops; instead, try to anticipate traffic and coast to red lights when safe. This reduces the engine’s workload and minimizes fuel waste from unnecessary acceleration and deceleration.

Lighten the load: remove any unnecessary heavy items from your Soul’s cargo area. Extra weight demands more power from the 2.0L engine, thereby consuming more fuel. Similarly, remove roof racks or cargo carriers when not in use, as they create aerodynamic drag.

Use cruise control on highway stretches. Maintaining a consistent speed prevents unnecessary acceleration and deceleration, allowing the IVT to keep the engine operating at its most efficient revs. This is particularly effective on flat terrain.

Perform regular maintenance according to Kia’s schedule. This includes oil changes, air filter replacements, and spark plug checks. A well-maintained engine runs more efficiently and delivers better fuel economy over its lifespan. For an in-depth look at SOUL MPG across all years, explore the data available.
