While many shoppers gravitate toward SUVs for various reasons — a high seating position, interior space, cargo versatility — gas mileage isn’t usually a primary concern. Nonetheless, myriad hybrid and plug-in hybrid SUVs are currently for sale, and a growing number of all-electric SUVs are joining them. Even a few gas-only SUVs these days are capable of exceeding 30 mpg in EPA combined fuel economy ratings.

To help SUV shoppers looking for the most fuel-efficient SUVs, we compiled the most efficient models for the 2021 model year in four categories: gas-only, hybrid, plug-in hybrid and battery-electric. We ranked them based on the EPA’s combined mpg rating or, in the case of battery-electric vehicles, combined mpg-equivalent rating. (The mpg-e rating, offered by the EPA for PHEVs, assigns energy equivalent to 1 gallon of gasoline.) For an SUV to make this list, it also needs to at least be offered with all-wheel drive, even if the two-wheel-drive version is the most fuel-efficient.

1. 2021 Lexus UX 200

Fuel efficiency doesn’t necessarily mean forgoing a premium nameplate, as the Lexus UX 200 demonstrates. Lexus’ entry-level SUV comes in two versions: the UX 200, which is FWD only, or the UX 250h hybrid, which has AWD. (The latter appears atop the hybrid rankings further down.) Those who opt for the gas-only UX 200 get a 169-horsepower, 2.0-liter four-cylinder engine paired to a continuously variable automatic transmission; the combo gets EPA ratings of 29/37/32 mpg. The bad news here is that Lexus recommends premium fuel for the UX, which will increase fuel costs considerably for those who oblige. (The owner’s manual, however, notes that regular unleaded is acceptable.)

2. 2021 Buick Encore GX, 2021 Chevrolet Trailblazer, 2021 Kia Seltos and 2021 Mazda CX-3 (Tie)

All four of these small SUVs attain 31 mpg combined, leaving them in a four-way tie by the EPA’s published ratings, which are rounded to the nearest whole number. If city mileage is more of a concern, buyers might lean toward the Encore GX, whose front-wheel-drive variant with a CVT automatic is rated at 30/32/31 mpg (city/highway/combined). The Trailblazer, meanwhile, shares a platform with the Encore GX but is rated at 29/33/31 mpg with FWD and the CVT. Highway aficionados might instead lean toward FWD versions of either the Mazda CX-3 or the larger Kia Seltos, which both have identical ratings of 29/34/31 mpg. Note that adding optional AWD to any of these models will lower their fuel economy.

Hybrid SUVs

Hybrids combine a battery pack and one or more electric motors with a traditional internal combustion engine. While some may offer driver-selectable all-electric modes to travel without using any gas, these are usually reserved for minimal distances, lower speeds and limited acceleration.

1. 2021 Lexus UX 250h

As we indicated above, the UX 250h tops the rankings for hybrid SUVs. While pricier than its UX 200 sibling, the UX 250h adds standard all-wheel drive and 12 hp extra thanks to its two integrated motor-generators. And while all those motors and their battery pack add weight, the UX 250h still turns out much better fuel efficiency than the UX 200: The EPA rates this small premium hybrid SUV at 43/41/42 mpg, with no recommendation for premium fuel as its UX 200 sibling has.

2. 2021 Ford Escape Hybrid

Where most hybrids add standard AWD and some use an electric motor to separately power the rear wheels, Ford still gives buyers the option of AWD or FWD with its Escape Hybrid. With FWD, the Escape Hybrid is rated at 44/37/41 mpg; adding AWD drops the city and combined ratings 1 mpg each for an overall rating of 43/31/40 mpg. A PHEV variant of the Escape is expected to go on sale at some point in 2021, but EPA ratings remain unpublished as of this writing.

3. 2021 Toyota RAV4 Hybrid

Among the more familiar hybrid SUVs out there, the Toyota RAV4 Hybrid includes standard AWD, and its hybrid powertrain puts out 219 total system hp. The RAV4 Hybrid nets a fuel economy rating of 41/38/40 mpg. Those looking for a RAV4 with more power and significant electric-only range should consider the RAV4 Prime plug-in hybrid, which has a considerably higher starting price but also becomes eligible for federal tax credits, and possibly state and local credits atop that.

Plug-In Hybrid SUVs

Plug-in hybrids have a charging port and, usually, a higher-capacity battery pack than conventional (which is to say, plug-free) hybrids. On a fully charged battery, they typically offer electric-only ranges in the tens of miles at a wide range of speed and acceleration — usually enough for a short commute.

1. 2021 Toyota RAV4 Prime

Here is the RAV4 Prime, boasting 42 miles of electric-only range, over 300 system hp and an EPA rating of 94 mpg-e. The RAV4 Prime is rated at 38 mpg combined in normal driving after electric range is depleted — just slightly below the traditional RAV4 Hybrid but still an impressive figure. In terms of efficiency over distance traveled, the EPA says the RAV4 Prime needs 36 kilowatt-hours to go 100 miles.

2. 2021 Subaru Crosstrek Hybrid

Subaru’s Crosstrek Hybrid, a PHEV despite no indication by name, is close behind the RAV4 Prime in terms of EPA-rated efficiency, with a 90 mpg-e rating and 35 mpg combined rating once all-electric range runs out. That range is a downside, however, as the Crosstrek Hybrid offers just 17 miles of all-electric range, which may only cover a one-way commute. The Crosstrek Hybrid is rated at 38 kwh per 100 miles.

3. 2021 Lincoln Corsair Grand Touring

Rounding out the top three is the 2021 Lincoln Corsair Grand Touring, a plug-in hybrid version of Lincoln’s compact SUV. It offers more all-electric range than the Crosstrek, at 28 miles, but a lower mpg-e rating (78) and combined rating (33 mpg) once all-electric range is depleted. The Corsair is EPA-rated at 43 kwh per 100 miles. Given the Corsair’s mechanical similarity to the Escape from Lincoln’s parent company, Ford, the plug-in Escape could see similar ratings once it arrives.
