Edmunds' Expert Review

The 2010 Mercury Mountaineer is one of the last of the old-guard SUVs with body-on-frame construction. Those who plan to tow large items should give it a look, but most consumers will be happier with a car-based crossover SUV.

Vehicle overview

What happens when you take an Explorer and slap a Mercury badge on it? Why, you get the 2010 Mercury Mountaineer, of course. Aside from minor styling and equipment differences, the Mountaineer is basically an Explorer by another name, which means it's a holdout from that bygone era when all SUVs employed tough body-on-frame construction. One notable difference is the Mountaineer's optional full-time all-wheel drive (the Explorer typically offers a true 4WD system with a low-range transfer case) that hints at its slightly more upscale intentions. This is an SUV for the suburban set. Trouble is, there are a slew of car-based crossover SUVs on the market now, and just about all of them are better choices for the suburbs than the dated Mountaineer.

The one thing the Mountaineer unequivocally has going for it is towing capacity. With a maximum rating of over 7,200 pounds with the optional V8, the Mountaineer can tow as much as some pickup trucks, whereas crossover SUVs typically top out at less than half the Mountaineer's limit. If you plan on towing trailers or boats on a regular basis, the Mountaineer actually makes sense. As vehicular workhorses go, this Mercury is pleasantly refined and luxurious.

As modern SUVs go, however, the 2010 Mercury Mountaineer is mostly outclassed. Its available all-wheel-drive system is matched by every notable crossover SUV, and a crossover's car-based chassis will always trump the Mountaineer's truck-style underpinnings when it comes to negotiating bumps and corners. Performance and fuel-efficiency are issues as well: The base Mountaineer's archaic 210-horsepower V6 is put to shame by virtually every other six-cylinder engine currently available, and neither the V6 nor the optional V8 comes close to matching the typical crossover SUV's fuel economy.

The Mountaineer does have some old-school SUV company. The Jeep Grand Cherokee, Kia Borrego, Nissan Pathfinder and Toyota 4Runner can all be counted as spiritual brethren, proving that there's still a market for nature-oriented 'utes even in this day and age. And for on-road use, the Mountaineer is actually a pretty good pick among this group. But the Mountaineer's on-road bias means you really should cross-shop it against crossovers more than traditional SUVs. And in this case, there are simply better choices than Mercury's rebadged Explorer.

Mercury Mountaineer models

The 2010 Mercury Mountaineer is a midsize SUV available in base and Premier trim levels. Rear-wheel drive is standard on both trims, with all-wheel drive optional.

Base models seat five and include 17-inch wheels, a six-way power driver seat, cruise control, full power accessories, a leather-wrapped tilt steering wheel with audio controls, and a stereo with a CD player and auxiliary audio jack. Optional is a Five-Passenger Value Package that adds power-adjustable pedals, driver memory functions, reverse parking sensors, running boards, dual-zone automatic climate control, rear manual climate controls, leather upholstery, heated power front seats, satellite radio and the Sync voice-activated communication and entertainment system. The Seven-Passenger Value Package features the same roster of goodies and tacks on a 50/50-split manual-folding third-row bench. Additional options include a sunroof and a tow package.

The Mountaineer Premier comes standard with 18-inch chrome wheels, rear parking sensors, aluminum-trimmed heated exterior mirrors with puddle lamps, aluminum roof rails, a sunroof, dual-zone automatic climate control, rear manual climate controls, leather upholstery, heated power front seats, driver memory functions and Sync. Options include 20-inch wheels, the tow package, power running boards, a power-folding third-row seat, a rear-seat entertainment system, second-row fold-flat bucket seats and a voice-activated navigation system with DVD audio and video capability, an internal hard drive, 10 gigabytes of music storage and an integrated real-time traffic feature that also provides local gas prices, movie times and sports scores.

2010 Highlights

Other than the deletion of a few option packages and some equipment reshuffling between trim levels, the 2010 Mercury Mountaineer is unchanged.

Performance & mpg

The 2010 Mountaineer's standard engine is Ford's 4.0-liter V6, which makes a lackluster 210 hp and a more respectable 254 pound-feet of torque. The Mountaineer Premier can be equipped with an optional 4.6-liter V8, which puts out a peppier 292 hp and 300 lb-ft of torque. A five-speed automatic transmission is standard with the V6, while the V8 comes with a six-speed unit. Both rear-wheel drive and all-wheel drive are available with either engine.

A V8-equipped AWD Mountaineer required 8.3 seconds to reach 60 mph in our instrumented testing. That's not bad, but the Toyota 4Runner is quicker, and many V6-powered crossovers put up comparable numbers. EPA fuel economy estimates for a rear-drive V6 Mountaineer are below-average at 14 mpg city/19 mpg highway and 16 mpg combined -- the V8 is actually better at 15/21/17. Opting for 4WD predictably lowers the ratings for both engines. Properly equipped, a rear-wheel-drive Mountaineer with the V8 can tow up to 7,220 pounds.


Standard safety features include antilock disc brakes and stability control with a rollover sensor. Airbag coverage includes front-seat side airbags and first- and second-row side curtain airbags, but airbags are not provided for the third row.

The 2010 Mercury Mountaineer fared quite well in crash tests, earning a perfect five stars across the board in all government frontal and side impact tests. It also earned the top rating of "Good" in frontal-offset crash testing conducted by the Insurance Institute for Highway Safety, but dropped to "Acceptable" (second-best) in side-impact tests.


Tuned for on-pavement use, the 2010 Mercury Mountaineer features a four-wheel independent suspension, which results in pretty good ride and handling characteristics for a traditional SUV. Still, crossover SUVs are notably better in both respects. Thorough sound insulation gives the Mountaineer a quiet highway ride, and the V8 is smooth and reasonably powerful. The V6, however, is disappointing, trailing rival V6-equipped models dramatically in both power output and fuel economy.


The Mountaineer's two-tone interior blends style and functionality with ease, and there's room for five, six or seven passengers, depending on your preference. The optional Sync phone/MP3 voice activation and hard-drive-based navigation systems are both effective and modern, but the rest of the cabin is decidedly dated. Most of the climate and audio controls include lots of similar-looking black buttons, while there are also some low-grade materials here and there.

Two adults can ride in the third-row seats on short trips, and children will be content sitting back there. The third-row option reduces available cargo space, but only slightly: Seven-passenger Mountaineers top out at 83.7 cubic feet, while five-passenger versions can swallow 85.8 cubic feet.

4.75/5 stars, Jia's Mountaineer
Premier 4dr SUV AWD (4.0L 6cyl 5A)
I replaced my '08 Explorer with a '10 Mountaineer. Even though I live at 5280 ft ASL my little 4.0 V6 runs like a rocket and this truck is beautiful. Gas mileage is what you would expect for a truck, about 14 MPG around town but I use it mainly for going to the gym, shopping, etc. Lots of room in the rear for big stuff and a DVD-video player for the grand kids (someday). Might be the last SUV I can buy with a truck frame under it. Nice sound system with bluetooth for hands-free phone. With the moon roof open I feel like I'm outside. Well protected with front and side airbags. This quiet truck will take my anyplace I need to go.
4/5 stars, Great Vehicle
4dr SUV AWD (4.0L 6cyl 5A)
Being one of the last true SUVs on the market this could use some improvement in the model offerings and options. I like the color, the new Flame Blue exterior and the black leather interior except for the hideous tan headliner. What a mismatch of colors. I have about 800 miles on it and the temperature is below freezing or zero and the gas mileage is 19.5 on dash computer. Fuel economy on this vehicle is under rated. Wish it would burn E-85. six speed transmission would have been nice also. Wanted Premier model but was not offered in 5 seat version. The AWD is super on the snow and ice. Very quiet and comfortable vehicle with lots of cargo space and back seat room.
2/5 stars, Great UNTIL....
Premier 4dr SUV (4.0L 6cyl 5A)
2010 Mercury Mountaineer bought 2 1/2 years ago with about 60k miles on it. I love how the 3rd row seats fold into the floor with a push of a button. I like the height, and my 90 year old friend can get in and out of the passenger seat without a step, with assistance. I have a toddler and it was nice not having to bed into a car to strap him into a car seat. The 3rd row seat is apparently pretty uncomfortable, and isn't easily accessible. It's ok for short trips on rare occasion. It got me around in hilly/rainy Pacific NW for 2 1/2 years without major repairs, until a couple months ago, at about 79000 miles. No accidents (only off-roading has been driveways). Despite routine maintenance, we've had to completely replace both the brake system and the power transfer case (total: about $5k), both destroyed due to the fluids inside leaking out. The thermostat, a hub, and the Navigation system have needed work or replacement as well. Every winter I've has to have a tube flushed due to debris (pine needles and such) coming in through the sunroof , causing rain in the car coming from the light console. (said indoor rain has killed a couple of my personal electronics). The Nav isn't user friendly anyway, I ended up using my phone most of the time anyway before it broke (or disconnected in the wiring?.. we're working on that problem now). Now I realize my descriptions may not be the most accurate, but my mechanic hubby understood and agreed with all the repairs, and has fixed some of it himself) If somehow it has very few miles on it I would say to get it, but otherwise I own a 6 yr old car with a lack of power that's required major repairs (that don't usually happen to cars under a decade old).
3/5 stars, Upgrade Gone Wrong
David Helms,
Premier 4dr SUV AWD (4.0L 6cyl 5A)
Previously, we had a 2007 Ford Explorer Eddie Bauer, but after it was totaled in an accident, we went with the Mountaineer for a "touch of class" so to say. The exterior is a little give and take... Yeah, it's nice and all, but when you park next to the previous generation Mountaineer; there really is not much of a difference. The interior is alright... It has the same options as the Explorer. I just wish it had came with better color combinations. Not to mention, it drives practically the same. It's a little disappointing honestly, I bought this thinking it would be a step above the Explorer, but it's kind of a step below. Reliability wise, it's solid. But beware of a few electrical issues here and there.

Should I lease or buy a 2010 Mercury Mountaineer?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
