I just bought this car and previously had a 2000 Volvo S-80 T6. This car is an outstanding road car and the low torque diesel provides excellent passing on the highway. It is as quick as my Volvo S-80 T6 and as smooth on the highway but with much better gas mileage and, I hope, a better built and longer lasting engine. One problem that has already surfaced that I hope Mercedes Benz is quickly working to correct is a shifting problem when starting out - the gears shift back and forth between first and second in a jerking motion. The problem duplicates when using the manual or automatic mode even when I try to start out in second gear. MB is aware of the problem and are investigating.

I traded a 2005 E320CDI for this 2007 BLUETEC. While my 2005 was a very good car, the handling of this BLUTEC is much improved, particularly the steering. The outside mirrors also are improved. I also have a transmision problem, it shifts jerky on take off, in first and second gear. Had it at the dealer several times for this problem. The dealer did confirm to me that Mercedes is aware of this rough shifting and is working on a solution. I was told it has something to do with the tourque curve of the diesel engine. I was given a Mercedes code number and was told the fix would happen after January first. I am sure Mercedes will get a handle on it very soon.

2007 E320 Bluetec V6 Diesel, Nothing major but bunch of small stuff that disables car for days. Cracked inter-cooler hoses, failed Mass Air Flow sensors, Failed EGR valve, Clogged DPF filter, scary one was when fuel filter clamp failed, sprayed fuel on hot turbocharger and ignited, my lucky day I was standing in traffic so I was able to see cloud of the smoke coming under the hood and can of soda put the fire out (I should let it burn). All this under 74K miles. This is my 8th Mercedes and seams that newer the car more problems with it.
An amazing ride, an amazing vehicle!

This diesel engine marvel is everything others have said about it: quiet, clean, LOTS of torque, and great gas mileage! Driving the car home from Texas I drove from Amarillo, TX to Holbrook, AZ on less than a tank of gas. I then drove from Snowflake, AZ to Salt Lake at 75-80 mph via Flagstaff (625 miles) with fuel left over for a few days of driving around town. Climbing mountain grades and passing other cars was effortless. The ride and handling were amazing. This is my first Mercedes and first diesel powered sedan. Given my experiences so far, I'm not going back to a gas powered car. It has the navigation system, which is nice, but easily outdone by my iPhone. It also has the Harmon Kardon audio system which is great. While it's almost 10 years old now, you wouldn't know it by how it handles. Later (Jan 2017): I've had the car for 8 months now. In that time it's had a few rather expensive repairs. I've had to have the o-rings in the oil-cooler replaced, the turbocharger has been replaced and there was an issue with the valve-body controller of the transmission. None of these have been cheap. I was fortunate I could swap out the turbocharger when I had the engine torn apart to replace the o-rings. I winced at paying $2000 to replace a $10 o-ring. But that said. I still consider myself money ahead on the vehicle. In real world driving I've gotten as much as 40mpg on one leg of a trip and average about 30-31 mpg between commuting to work and driving around town. The body and interior are so nice, people are surprised to learn it's a 2007. Would I buy this car again? Probably. Will I drive anything other than a Mercedes? No way! When I ride in other cars, I can tell the difference, both in noise levels and ride quality. It's superior to any Japanese or American-made vehicle. Later (June 2018): It's been two years now that I've had the car. I've put more than 30,000 miles on it. In that time, besides tires and brakes, I've replaced the navigation DVD and the engine motor mounts. The car is still a dream to drive. It looks as nice inside and feels as solid on the road as the day I bought it... better even. Mercedes are expensive to maintain there's no denying, but for me the quality of the ride is worth it. I still have it serviced according the the prescribed maintenance schedule. It helps having an excellent Mercedes dealer near by. I don't know what other owner's experiences are with their dealers, but mine, Mercedes of Draper is amazing! Free rotations. Free carwashes. Free emission inspections. The list goes on. And all because I have them perform the scheduled maintenance. I plan on keeping the car for as long as I can. I have no regrets buying it.

38MPG highway

I've owned some very nice vehicles (Porsche, BMW, etc) but this is without a doubt the finest sedan I have ever owned or even ridden in. Smooth, quiet, comfortable with excellent handling and almost shocking acceleration. Unlike most cars (especially hybrids), the EPA rating is accurate. Took it on a long trip recently and got 38MPG with the cruise set at 75. I see no reason at all to even consider an E350. Ultra low sulphur diesel is still a bit hard to find but getting better every week. What's in the tanks at most gas stations is usually ULSD but most stations haven't been certified yet. Luckily, I only have to look for fuel about once or twice a month.
Bluetec's the way to go

My 3rd Benz. 1990E class loved it.2000 S500,had trouble with it. Now this Eclass.So far great. I tend to go back and forth between Benz, BMW,and Lexus. I wanted good mileage, but more fun luxury and performance than a Prius, which I drove as well. I am dissapointed with the direction of the Lexus hybrids(poor mileage). It came down to the Lexus GS450h vs Benz E320 bluetec. Benz won this time around.

Had a turbo replacement for the 05 CDI with no engine damage at 149,000 miles - no problem. Just was informed by the Greenwich Penske/MB dealer that the 2007 Bluetec had a blown turbo which destroyed the engine. Cost to repair $13,000.00 - market value around $8,000.00. The turbo parts enter the engine itself and destroy it. A known design problem which has happened to thousands of Bluetec's. MB Corporate says: "Tough, car is out of warranty - we decline any responsibility. We can refer you to a good junk dealer. Update: 6/30/2018 Had to junk the 2007 Bluetec. I am left with a 2008 Bluetec and the above mentioned 2005 CDI. I am now changing oil every 5,000 miles. When parking either car I let the engine idle for some time to cool the oil in the turbo before removing the key. I originally bought the three Diesels on the recommendation of Consumer Reports in 2007. During the last five to eight years CR does not even mention that there are MB Diesels. All in all a most unsatisfying experience at the Greenwich, Ct Penske dealership and MB Corporate. Never again an MB. Edmunds requested an update to the above saga. Based on my previous report I finally managed to sell all three Bluetecs. At age 92 I am (or) was a lifelong MB driver. Never again !!!

I just picked up a CPO 2007 E320 Bluetec. This is my 3rd Mercedes-Benz diesel ('74 240D 4 speed - 440K miles on it when the engine died due to loss of oil, and an '84 300D turbodiesel - sold at 337K miles and it's still running strong, from what I hear. This one is by far the best of them - I cannot imagine a car needing anything more than this car offers - quiet, fast, excellent fuel economy, beautiful build quality - it's all there. Only concern I had was repair cost, so I extneded the CPO warranty by two more years, to get me through 2013 - it was certainly cheap insurance, considering the labor rates and parts costs if something does go wrong out of warranty.

Repair costs are high. the turbocharger went out before 75K and at a cost of 5,000 to replace. At the time there were no rebuild kits available. Had to replace the oil cooler from leaking, the manifolds seem to clog early. The after market warranty policies are not worth the paper, but that is another story.

I have had my Bluetec for a little over a year, tons of power and torque. You could not guess you are driving a diesel. It is fast, quiet, luxurious, and most of all economical, getting 26 mpg around town and 32-34 on the highway. The $1,000 premium for the diesel over the E350 is worth it,( just look at resales between the E320 vs E350) test drove both with little to no difference in performance or comfort. Love the classic understated good looks, the pre-safe technology, and all the other safety features. Once I drove this car I questioned why would I drive any other car in this class ( test drove E350,BMW 528I, Cadillac STS, Infiniti M35, Lexus GS350).

I love cars and the Bluetec is fun to own. Diesel power is amazing, liked the pull/torque better than the 350 gasser. Smooth and quiet. Not a handling machine, but this is a lux cruiser, not a sports car. 7-speed trans is great with the diesel's short power band, but it's a little jerky when cold. Smaller brakes than the 350 with larger wheels, but same tested stopping distance. Styling is subdued and refined, so I'll like how it looks for the long haul. HK sound system is really good. Nav works well, updates quickly, but a pain to enter addresses.

Having previously driven various BMW and MB models over the past 20+ years, my 2008 Bluetec is the best yet. The astounding torque has to be experienced to be believed. Passing performance is rocket-like. Trips to gas stations have become far fewer. All of the wonderful features of the E Class are combined with the superb V6 diesel. Why would anyone looking to buy an new E Class (or a similar luxury sedan) not consider the amazing E320 Bluetec ?? If V8 power combined with 4 cylinder fuel economy doesn't make sense, then what does ?

Cars don't get much faster and more fuel efficient than this BlueTec diesel car. There are almost 400 foot pounds of torque and almost 40 miles per gallon. Why buy a Lexus or Toyota or BMW when you will be slower, and consuming more fuel. Plus, the other cars' value will drop like a rock in a few years. I am pleased, very pleased with the MB E320 BlueTec. This is epitome of engineering and pizzazz!
163 K miles and still looks and drives like new!

This is my third diesel MB. I absolutely enjoy driving it. Bought it used with 70K put almost 100K . Only recently I had to replace fuel pump, oil sensor and oil cooler seal set (ouch $$). Otherwise my expenses were limited to regular maintenance, tires etc. I average about 32-33 mpg with highway driving approaching 38-39 mpg! Incredible, in vehicle with 400 lbs of torque! It is an amazing cruiser, quiet, comfortable and safe. I am thinking of driving it till 240-250 K miles before I part with it. I can’t think of another vehicle that offers similar mix of performance, safety, comfort, economy and class. My 2007 MB E320 Bluetec still looks sharp and current. Truly a timeless car.

Update on Mecedes E-320 BLUETECH

I recently submitted a review of my new 2007 Bluetech. In this review I stated the problems I was having with the 7 speed transmission. I am happy to tell you that Mercedes has installed new software to eliminate this jerky shifting problem. My local dealer and Mercedes in Germany was involved in this process. It has been a week now since the update and the transmission is now shifting as smooth as silk. In fact, the transmission is shifting much more positive throughout the entire speed range. I think Mecedes and my dealer has done a great job solving this shifting problem and eliminating it. The entire process took about one hour. I thought you like to hear the good news.

I've owned a BMW, a Lexus, a Corvette, two Subaru's, and two prior Mercedes. The Bluetec gets the ribbon. It has a tight, solid, heavy and luxurious feel, but the torquey motor gives it plenty of punch. I feel safe in this car, even at high speed. It has air bags everywhere, and the TeleAid system (similar to OnStar). It has a tight turning radius and is no problem to park. Visibility all around is excellent. And it is not ostentatious to the point that vandals want to mess with it. The automatic tranny does have the annoying and well-known habit of "hunting" between 1st and 2nd briefly when starting out, but I've learned to ignore it! My friend's Audi had the same problem. No biggie to me.

This is my first MB and I bought it for reliability, economy and style and it has not let me down. Economy is amazing. I get 26 mpg in town and 28- 30 mpg on my 55 mile commute (at 80- 90mph!). Passing is effortless and silent, it really has quite a good mid- range punch. The 580 mile range is also great, a lot less time is spent at the pump. A 13,000 mile service interval is also a time saver. You can hardly tell that it is a diesel at all. The motor only rattles at low rpm, low speed with the window down. I've had just one issue, a buzzing speaker which was fixed under warranty. One small gripe is turbo lag, but you learn to drive around it. Buy one!
Great car!

My first Mercedes and I'm very impressed. Test drove a 2006 E320 CDI last year and the difference between the 2006 and the 2007 model is substantial. The 2007 is much more quiet both inside and out. The torque produced by this engine is amazing. Considered a Lexus GS but this Mercedes just presented a more luxurious profile to me. The dealer I purchased from also installed the 18" 10-twin-spoke rims which really made this car stand out.

This is an excellent all round vehicle. I opted to upgrade the wheel package to 10 twin spoke alloys - why these are not offered as standard as they are on the E350 surprises me

Purchased a CPO E320 Bluetec with 24K miles. Impressed with build quality, drive ability, features. I'm 6'4, 220 lbs, and have plenty of leg, hip and headroom both as a driver and as a passenger (can sit comfortably behind driver's seat which was set to my specs). Took a 1K mile shakedown to NW PA and averaged about 35.5 mpg in mostly highway driving between 70 - 75 mph. Stone quiet, provides a great sense of confidence in ride and handling qualities. Only quibble is the COMMAND radio system, for its apparent sophistication, has no satellite radio standard. I do not miss nav - that's why I use AAA maps!

Just purchased a CPO Bluetec with 24K. Dealer experience was excellent. In two weeks have put on two thousand miles of primarily highway driving between 70 - 76 mph. Average MPG is slightly over 35. Systems are A-1; everything is intuitive. Extremely comfortable and supportive seats in MB Tex. Will check back in after first D service in 8 K miles.

I'm no stranger to performance cars,but i must say this new E 320 blutec is more fun to drive than my '06 911. The rush of power and creamy smooth ride low noise decibels, getting almost 40MPG! I was going for a S550 and test drove this E blutec and WOW.
