What's New for 2010

The 2010 Mercury Grand Marquis is unchanged.


The 2010 Mercury Grand Marquis is the sort of car that completely validates this Web site's existence. Get a load of the marketing spin in Mercury's official description. "Most standard horsepower in its class," reads the company fact sheet. What they conveniently fail to mention is that the Grand Marquis and its underperforming 224-horsepower V8 are in a class of one -- there's nothing to compete against. Don't listen to Mercury; listen to us. The hoary Grand Marquis is a couple decades past its prime.

As the only remaining rear-drive, full-size body-on-frame sedan other than the related Lincoln Town Car, the "MGM" has simplicity and proven dependability working in its favor. Otherwise, the livery and law-enforcement sectors wouldn't have leaned so heavily on the Grand Marquis and its now-defunct Ford Crown Victoria twin. The MGM also has six-passenger seating and a colossal 20.6-cubic-foot trunk. But there are good reasons why cars are no longer built like this big old Mercury.

Let's start with that V8 -- you know, the one with the most standard horsepower in its class. In fact, you would be hard-pressed to find a V6-powered sedan these days that makes fewer than the MGM's 224 hp. The similarly outdated Chevy Impala has a 3.5-liter V6 rated at 211 hp, and the lackluster Kia Optima offers a 2.7-liter V6 with 194 horses. Maybe you could dig up a couple other examples if you tried. But here's the reality: Every reasonably competitive V6-powered sedan on the market has more power than the Grand Marquis' 4.6-liter V8, while modern V8s are simply in a different league.

Other quaint Grand Marquis features include a four-speed automatic transmission, unsupportive seats and handling and steering straight out of the 1970s. Price? Almost $30,000 to start. Any other $30,000-plus car will likely be more enjoyable to drive and own than the MGM, but we would specifically point you toward large sedans like the Chrysler 300, Hyundai Genesis, Toyota Avalon and Ford's own Taurus. If you came to this review for sage buying advice, here it is in a nutshell: Don't spend your hard-earned money on a 2010 Mercury Grand Marquis.

Body Styles, Trim Levels, and Options

The 2010 Mercury Grand Marquis is a full-size sedan offered in a single LS trim level. Standard equipment includes 17-inch alloy wheels, rear air suspension, keyless entry and exterior keypad entry, auto on/off headlamps, foglamps, cruise control, full power accessories, automatic climate control, an auto-dimming rearview mirror, a 40/20/40-split front bench seat with driver power adjustments, leather upholstery, a leather-wrapped steering wheel and a CD player.

Options include chrome-clad wheels, heated front seats, a leather/wood steering wheel with audio and climate controls, power-adjustable pedals and a "dual media" stereo that bundles a CD player with probably the only optional cassette player in any 2010 model.

Powertrains and Performance

The rear-wheel-drive 2010 Grand Marquis is powered by a 4.6-liter V8 coupled to a four-speed automatic transmission. Output is 224 hp and 275 pound-feet of torque. Fuel economy is 16 mpg city/24 mpg highway and 19 mpg combined.


Standard safety equipment includes antilock disc brakes, traction control and front-seat side airbags. Stability control and side curtain airbags are not offered. Nonetheless, the Grand Marquis has fared well in crash tests by the National Highway Traffic Safety Administration, scoring a perfect five stars for both frontal and side impacts. However, while the big Mercury earned the top rating of "Good" in frontal-offset crash testing conducted by the Insurance Institute for Highway Safety, it garnered a "Marginal" rating -- second worst on a scale of four -- in side-impact crash testing.

Interior Design and Special Features

The Grand Marquis has a spacious interior that can seat up to six thanks to an old-school three-person front bench. The leather seats are no more supportive than your couch, however. The controls and instruments are simple and easy to decipher, but the overall design is dated, and some controls are difficult to reach. Materials quality is predictably subpar. If you've taken a cab to the airport in the last 15 years, you already know the 20.6-cubic-foot trunk is capable of swallowing copious amounts of luggage or several sets of golf clubs.

Driving Impressions

Driving the 2010 Mercury Grand Marquis is like taking a trip back to the 1990s, which is great if you like grunge and neon colors, but not so appealing if you want a modern automotive experience. While rival full-size sedans generally provide decent handling and driver control, the MGM's prodigious size, cushy suspension and zero-effort steering combine to simulate the experience of piloting the Goodyear blimp. The V8 provides healthy torque off the line but not much after that -- zero to 60 mph requires about 8.5 seconds, which is close to four-cylinder territory by current standards.

Good old american car

Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

I bought a new 2011 Hyundai Sonata on an impulse. I regretted after a very short time and started looking for something bigger with a more comfortable ride at a reasonable price. I found it in a used 2010 Grand Marquis. Yes, it's a dated car with virtually no "technology" (except the AM/FM radio with CD) but the car is an absolute pleasure to drive. 27 MPG highway last trip. Seats are very comfortable. I'm 6'3" and my legs do not come close to the dash and there is a lot of headroom (even while wearing a hat). The car will not do "wheelies" but at my age, who cares? The point for me is total comfort and peace of mind: Grand Marquis has both. If you can find one, buy it!

Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

Lots of bang for your buck with this one. Even though it's a throwback to the 70s (same platform since late 70s) and the sheet metal is virtually the same for the last 15-20 years; the simplicity of owing this vehicle, the reliability and comfort that comes with it can't be matched. If you're looking for a car that rides good, is big and comfortable, this is your car.

4 in a row!

Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

I am about to buy my 4th Grand Marquis. First was a 1997. Need room for 4 adults, and trunk big enough for wheel chair, also wanted an V8 with posi-traction to pull my boat out every once in a while. It was trouble free all I ever did was change the oil. Sold it and the last I heard it has 240K miles on in and is still going. Bought a 2000. Same thing. Trouble free!Bought a 2005 have 90K on it and drove high speed highway driving. 24MPG and except for a broken cable in the drivers window it has been trouble free. All these cars are workhorses. The Best American made car as far as I am concerned. Also the best car for the money. Very sorry they have discontinued this winner!

Good car

by on
Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

I think Ford is making a mistake discontinuing this car. I love the room and power. The Mileage could be little better but good for big car. I noticed it does catch alot of side wind and the windshield holds the hard rain so visibility is poor during that. My Nissan Pathfinder did much better with the wind and rain. I still like the Merc Grand better overall. I'm just turning 50yrs but enjoy driving this car. The comfort is great. I hesitated at first during purchase because design is so retro but it has grown on me now and I really like it. You can see around during driving very good and changes lanes very stable with no sway at all. Bring it back Ford, be smart.

Great value

Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

This car hasn't changed in years and that's why it is good. They've got all the problems worked out. You can usually pick up a new for 25K at the end of the year. You can pick up a 3 year old used one for $10k that will go another 100K miles. Highway mileage is 27. And those are non-tiring miles. It's extremely safe. You can tow. I built a roof rack and can haul lumber like a pickup. A used one would make a great family car for someone with not much to spend. The only drawbacks would be comments from your friends. But you can laugh all the way to the bank.

Edmunds is wrong

by on
Vehicle: 2010 Mercury Grand Marquis LS 4dr Sedan (4.6L 8cyl 4A)

I see Edmunds has graciously given the GM a 6.5 where the owners have a 9.1. I will agree with the owners. Yes this car is outdated which caused me to keep looking. I kept coming back. It now has features no other car has, bench seats. All the newer cars have copied the Euros and the Japanese with bucket seats and hamster motors. These killed my back and I am not a senior citizen. My back does not hurt anymore and I actually look forward to going to work ( gliding to work). Flew to Las Vegas and road tripped it home at 27 MPG. I am getting 20.3 driving to work. My 08 Sentra only got 30. Edmunds, you keep your Acuras & Hondas with the narrow seats. My American bottom will be in an American car.
