Who it suits. Drivers needing a 4WD gasoline pickup Buyers comfortable with 18 MPG combined fuel economy Mixed city and highway driving

The Frontier 4WD PRO4X is a clear fit for someone seeking a Nissan pickup with part-time four-wheel drive rather than a fuel-sipping vehicle. It uses a gasoline 3.8-liter six-cylinder engine and a nine-speed automatic transmission, while the EPA figures point to a meaningful running expense. At $3,700 in annual fuel cost, this model deserves a place on the shortlist only when its drivetrain and pickup body matter more than minimizing fuel bills.

What it is

The 2027 Nissan Frontier 4WD PRO4X is a standard-size 4WD pickup. It uses gasoline, a 3.8-liter six-cylinder engine, and an automatic transmission with nine speeds.

Its defining EPA figure is 18 MPG combined. That rating describes the truck's overall fuel use across city and highway driving.

The numbers

EPA rates the Frontier 4WD PRO4X at 16 MPG in city driving and 20 MPG on the highway. Stop-and-go trips align with the lower city figure, while steady highway travel aligns with the higher one.

The truck's tailpipe output is listed at 504 grams of CO2 per mile.

What it costs to run

EPA lists annual fuel cost at $3,700. With an 18 MPG combined rating, fuel use is a central ownership cost for this gasoline pickup.

How it compares

Against other vehicles in the standard 4WD pickup group, use the combined MPG figure first, then check the separate city and highway ratings for your routine.

Who it suits

This truck suits a buyer who wants a gasoline pickup with part-time four-wheel drive and accepts 18 MPG combined fuel economy.

It fits drivers whose mileage is split between city and highway roads, since EPA provides distinct ratings for both.

Trade-offs

Part-time 4WD gives this pickup a different drivetrain setup from two-wheel-drive trucks, while the 3.8-liter six-cylinder and automatic transmission add to its pickup-oriented configuration.

The trade-off is fuel use: 16 MPG city, 20 MPG highway, and a listed $3,700 annual fuel cost.

Verdict

Choose the Frontier 4WD PRO4X if a Nissan pickup with part-time four-wheel drive matches your needs and you can budget for its fuel use. Its 18 MPG combined rating is straightforward, with city driving rated lower than highway travel. Buyers focused on reducing gasoline spending should compare that figure with other standard 4WD pickups before deciding.
