The 2023 Mitsubishi Outlander PHEV, with its combined EPA rating of 26 MPG, isn’t going to win any hypermiling competitions. But that number is deceptive because it doesn’t tell the whole story of how this plug-in hybrid is intended to be used. The Outlander PHEV appeals to a specific buyer: someone who wants a three-row SUV, values electric driving for daily commutes, and needs the reassurance of a gasoline engine for longer trips. For them, the 26 MPG is an acceptable compromise, a worst-case scenario that’s often avoided entirely.

City and highway performance

The EPA breaks down that 26 MPG figure into 25 MPG in the city and 27 MPG on the highway. Interestingly, the city rating is only marginally lower than the highway. This is due to the Outlander PHEV’s regenerative braking system, which recoups energy during deceleration in city driving, helping to maintain battery charge and minimize gasoline consumption. On the highway, where the gasoline engine is more consistently engaged, the MPG figure is slightly higher, but the difference isn’t dramatic, showcasing the relatively consistent efficiency of the 2.4L four-cylinder engine in hybrid operation.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mitsubishi Outlander PHEV at $1,700. This figure is based on driving 15,000 miles per year, using a national average fuel price. It’s important to remember that individual fuel costs will vary based on driving habits, local fuel prices, and the amount of electric-only driving you do. Someone who primarily uses the Outlander PHEV for short commutes and charges it regularly will likely spend significantly less than this figure. Conversely, someone who frequently takes long road trips and rarely plugs in will spend more.

Real-world expectations

The official rating of 26 MPG is only part of the picture. The real-world experience is highly dependent on how frequently the Outlander PHEV is charged. With a full charge, the vehicle can travel a significant distance on electric power alone. A driver who consistently plugs in and uses the electric range for their daily commute might see their actual fuel economy number rise dramatically, potentially exceeding 50 MPG, or even running entire weeks without using any gasoline at all. However, once the battery is depleted, the Outlander PHEV operates as a traditional hybrid, and the MPG will hover much closer to that 26 MPG rating.

How it compares

Compared to other plug-in hybrid SUVs, the 2023 Mitsubishi Outlander PHEV’s fuel economy lands in the middle of the pack. The Toyota RAV4 Prime, for instance, boasts a combined rating of 38 MPG *with* the benefit of electric driving and 40 miles of all-electric range, making it significantly more efficient when factoring in its hybrid capability. The Kia Sorento PHEV achieves 34 MPG combined when using the gasoline engine and 32 of electric-only range. However, the Outlander PHEV offers a unique advantage: third-row seating (albeit small), which neither the RAV4 Prime nor the Sorento PHEV provide. This is an important factor for buyers who need occasional extra passenger capacity and are willing to trade some fuel efficiency to get it. Review OUTLANDER MPG across all years to understand how this compares to previous model years. You can also compare with all Mitsubishi fuel economy data.

Tips to maximize efficiency

The most effective way to improve the Outlander PHEV’s fuel economy is to maximize electric driving. Plug in whenever possible, even for short periods. The more you rely on electric power, the less gasoline you’ll use, and the lower your overall fuel costs will be.

Take advantage of the Outlander PHEV’s regenerative braking system. Anticipate stops and ease off the accelerator early, allowing the system to recapture energy and slow the vehicle. Avoid sudden braking, which wastes energy and relies more heavily on the friction brakes.

When driving in hybrid mode, select the “Eco” mode to optimize fuel economy. This mode adjusts the throttle response and other vehicle systems to prioritize efficiency over performance. While it might slightly reduce acceleration, it can make a noticeable difference in gasoline consumption.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level. This is particularly important for a heavier vehicle like the Outlander PHEV.

Minimize unnecessary weight. Carrying extra cargo adds to the vehicle’s load which makes the engine work harder, especially when climbing hills or accelerating. Remove any unnecessary items from the trunk or roof rack to improve fuel economy.
