2012 Mercedes-Benz R-Class Review

By

KBB Expert Rating: 6.4

The 2012 Mercedes R-Class is an unusual vehicle. It's definitely not a minivan nor is it really a crossover (even though that's what Mercedes-Benz calls it). Rather, the 2012 Mercedes-Benz R-Class has staked its territory as a no-nonsense rolling monument to practicality. With comfortable seating for six, standard all-wheel drive and the option of a diesel engine, the R-Class puts some of the best-selling SUVs on the road to shame. The R-Class suffers from puzzling nomenclature. The gasoline-fueled version is called the R350 4MATIC, while the diesel-burning variant is the R350 BlueTEC. Both have all-wheel drive.

You'll Like This Car If...

With its solid construction, luxury touches and practicality, the 2012 Mercedes-Benz R-Class is a pleasant refuge from both SUVs and, especially, crossovers with false off-road pretensions.

You May Not Like This Car If...

If you must parallel park in your neighborhood or don't have a bunch of children to transport about town, you may find the R-Class to be more car than you need.

What's New for 2012

For 2012 the biggest change to the R-Class is the R350 4MATIC's new V6 engine. This 3.5-liter V6 makes 302 horsepower, 34 more than last year's gasoline-fueled V6. Other new standards include LED daytime running lights and Mercedes' COMAND personalization system for sound system, navigation and more.

Driving the R-Class

Driving Impressions The new V6 in the 2012 Mercedes-Benz R350 4MATIC is a welcome addition. While not hair-raising in any way, the extra horsepower does its part to put a spring in...

the R-Class' step. Mercedes-Benz's 4MATIC all-wheel-drive setup is great as usual and makes for a great year-round people mover. With copious amounts of low-end torque, the 2012 Mercedes-Benz R350 BlueTEC is quick enough to keep you from lamenting the diesel engine. The 7-speed automatic transmission finds its place admirably, and both R-Class models are smooth and competent through corners. Excellent braking and turning radii make the R-Class even better an everyday driver.

Diesel Power
If you wish more good diesel engines were available in the U.S. and you don't try a 2012 R350 BlueTEC you're part of the problem. This great engine proves the viability of the right diesel in the right machine.

Second-Row Seating
We can't tell you what a joy it is to see second-row seats with such comfort and adjustability. Anything that can be done to reduce acrimony and complaint from the back is a good thing in our eyes.

2012 Mercedes-Benz R-Class Details
Interior

Interior design and amenities in the 2012 Mercedes-Benz R-Class are top notch. The cabin is spacious, as are the second- and third-row seats. Rear-seat passengers have seat adjustments, cup holders and an optional dual-screen DVD player. Elegant wood trim along with the well-integrated monitor of the COMAND system goes a long way toward keeping Mom and Dad sane.

Exterior

Some may find the 2012 Mercedes-Benz R-Class' angular hatch unappealing, particularly taken in context with the elegant swooping rooflines of other Mercedes models. Then again, when the kids' (and your neighbors' kids') and their hockey gear is loaded up, you may not mind so much.

Notable Equipment
Standard Equipment

The biggest change for standard equipment in the 2012 Mercedes-Benz R-Class is the COMAND system. Both the conventional and diesel models retain 4MATIC all-wheel drive, power sunroof and Bluetooth connectivity as standards. The 19-inch wheels are a nice styling touch, and there are two new exterior paint options available.

Optional Equipment

Likely the most appealing option for the 2012 Mercedes R-Class is the dual LCD screens for the rear passengers. There is also an optional sound system and keyless starting system. For the consumer who wants to squeeze a bit more style out of the R-Class, 20" wheels are available.

Under the Hood

The upgraded V6 in the 2012 R350 4MATIC helps alleviate some issues with power relative to weight load in the previous model. Also a little extra horsepower never hurts. The diesel remains an outstanding option for fuel economy without feeling bereft of all acceleration and engine response.

3.5-liter V6
302 horsepower @ 6,500
258 lb-ft torque @ 2,400-5,000 rpm
EPA city/highway fuel economy: 16/21

3.0-liter V6 turbocharged diesel
210 horsepower @ 3,400 rpm
400 lb-ft torque @ 1,600-2400 rpm

"I've owned my R350 for 3 years now, and it has been a eye opening experience. I have never cared for or been a fan of German luxury but I can see where mercedes was going with this car ...it works for me......it fits my life style. It's a luxury car when you go out, it's a truck when you have to haul stuff from Home Depot , it's a snow mobile in the worst snow storm. It's a great vehicle to own but! ......you will have to be a little mechanically inclined. The first time the check engine light came on , the cost of the total repairs came out to $11,000. So I soon became a owner of a hand held obd scanner to read out the "check engine light" codes and look up how to fix it it myself and saved a lot of money doing it myself. Now the R350 is a lot easier to own. Unless your financially set to pay a mercedes Benz specialist every time that dreaded "check engine light comes on.....you better get familiar with the car. Ok, but overall I looked at plenty of cars and trucks and I still think that the R350 is the best car for me. Style ,function, and drivability nothing can beat it."

"I have owned the car for over 6 years and drove over 128,000 miles and I don't feel comfortable driving long distances. A faulty Engine Gas Exhaust Temp Sensor will kill the motor and your stranded on the side of the freeway until it cools down. There is some stray electrical issues and I am always replacing light bulbs. Bought it brand new, the sun roof window shade broke the first week (2 days to fix, thank God it was still under warranty). 40,000 EGT Sensor failed ($260 for Diagnostic, $220 part and $199 labor). 60,000 steering rack developed a serious leak ($4600). Replaced front headlights because of hazing plastic ($650). Transmission issues started 100,000 miles ($740). Whats next? I am completely disappointed and will never buy another Mercedes again."

"Since the R-class styling was not very popular, I felt I got a lot of car for my money, especially since I very much like the practical, aerodynamic style. I had one $800 repair in 3 years. The interior is sedate, comfortable, and very quiet. The car handles well, and gets up to 30 mpg cruising at 75."

"This is my first Mercedes, and I love it, but was amazed at how much work was required. When I bought it at 60,000.00 miles it immediately needed shocks, suspension air bags, and new rack and pinion. Also the mechanical opener for the hatch had to be replaced. The seats are a pain to adjust for the cargo space."

"Exactly what I require, however, my servicing dealer's maint personnel have not performed some very elemental repairs, in OKC. The vehicle has been in for service for the same thing 4 times. The service has never been correctly performed. It is in for service at this time and am dealing with a different service person. Hopefully will be satisfactory."

"This is a great layout for a family car. It rides like a dream, and with all of the seats folded down, there's little that can't be carried in it. If I could keep the build, and replace everything mechanical about it, I would. At only 65K on a babied, well-maintained car, I have had to replace both rear air struts within 6 months of each other (approx $700 each). Also, the manifold is currently being replaced due to a bad flap ($1600 total repair). The tailgate back sensor has never worked properly, nor have the parking sensors (they go off randomly when driving down the road). I am now being told that the thermostat and cam sensors need to be replaced as well. Even with the car paid off, the repairs are no longer worth keeping the vehicle, which is a real shame. I love the R-Class body, and it is amazing in so many other ways. But it is the most unreliable car I have ever owned."
