2010 Mercury Mariner 4WD: the full review

The 2010 Mercury Mariner 4WD combines an SUV body, four-wheel drive and a six-speed automatic. Its 22 combined MPG and listed annual fuel cost of $3,050 help frame the fuel-cost tradeoff for shoppers.

Overview

The 2010 Mercury Mariner 4WD is a gasoline-powered SUV with four-wheel drive, a 2.5-liter four-cylinder engine and a six-speed automatic transmission. Its EPA fuel-economy ratings are 20 MPG in the city, 26 MPG on the highway and 22 MPG combined. The official EPA estimate for annual fuel cost is $3,050, and tailpipe carbon dioxide emissions are 403.95 grams per mile.

Those figures make fuel use a central consideration for buyers comparing this Mariner with other vehicles. Its city rating is lower than its highway rating, while the combined figure provides a single estimate for broad comparisons. Actual fuel spending depends on driving and fuel costs; the listed annual estimate is the EPA figure.

Key features

Body: SUV.
Drive: Four-wheel drive.
Engine: 2.5-liter four-cylinder gasoline engine.
Transmission: Six-speed automatic.

The supplied specifications identify the powertrain and drivetrain, but do not provide equipment, passenger or cargo capacity, or towing details. Buyers who need those specifics should confirm them for the particular vehicle.

Platforms

EPA fuel economy is 20 MPG city, 26 MPG highway and 22 MPG combined. The EPA annual fuel-cost estimate is $3,050, with tailpipe emissions of 403.95 grams of CO2 per mile. These figures offer a consistent basis for comparing fuel consumption, but do not describe maintenance, insurance or other ownership costs.

Who it's for

The Mariner 4WD may suit shoppers seeking a gasoline SUV with four-wheel drive and an automatic transmission. It is also relevant to buyers weighing the trade-off between that drivetrain and the listed fuel-economy figures. For fleet or business use, the annual EPA fuel-cost estimate can help frame comparisons, though it is not a complete operating budget.

Pros and cons

Potential advantages

Four-wheel drive is specified alongside a conventional gasoline powertrain.
The EPA ratings and annual fuel-cost estimate give buyers concrete figures for comparison.

Considerations

Available facts do not establish equipment, condition, or actual costs for an individual vehicle.

Alternatives

For a later four-wheel-drive version, compare the 2011 Mercury Mariner 4WD with the 2011 Mercury Mariner 4WD FFV. The 2011 Mariner lineup also includes the 2011 Mercury Mariner FWD, 2011 Mercury Mariner FWD FFV, 2011 Mercury Mariner Hybrid 4WD and 2011 Mercury Mariner Hybrid FWD.
