Shopping for a 2012 clean diesel car and thinking about the Mercedes-Benz E350 BlueTEC sedan? Here’s a summary of major reviews of the vehicle to help you decide. Be sure to leave a comment at the bottom if you have questions, or something to add!

Perhaps the most eye-opening news about the 2012 Mercedes E350  is the 3.0 liter BlueTEC diesel engine, which generates 210 horsepower, sprints from 0 to 60 in 9.0 seconds and has a fuel economy rating of 21 MPG in the city and 32 MPG on the highway. The E350 diesel comes only in rear-wheel drive with a 7-speed automatic transmission. The MSRP runs from $50,490 to $88,900.

AOL Autos – 2012 Mercedes-Benz E-Class Expert Review

AOL Autos reports that “We particularly like the diesel-powered E350 BlueTEC sedan. Mercedes’ V6 turbodiesel is the smoothest, quietest diesel engine available, so virtually all the smoky, clattering drawbacks of more traditional diesel power are gone (though the oily diesel smell during fill-ups remains). Performance is virtually identical the gasoline-powered E350…”

Leftlane – 2012 Mercedes-Benz E350 BlueTEC

The reviewers at Leftlane said, “What makes the E350 BlueTEC different from other models in the E-Class range is the 3.0-liter diesel V6 under the hood. Though its output of 210 horsepower isn’t impressive, the motor also produces a mighty 400 lb-ft of torque from just 1600 rpm. Hooked up to a polished seven-speed automatic transmission, the mill facilitates effortless passing while also returning notable fuel economy: 22 mpg in the city and a superb 33 mpg on the highway.” They also report that the E350 has a new powertrain for 2012.

They also note that “Like other E-Class models, the E350 BlueTEC recently received a complete redesign covering both the exterior and interior. Outside, the car’s styling could best be described as edgy traditionalism: there are more hard edges and surface creases than on previous models, but overall the look is unmistakably Mercedes Benz.”

Describing the interior, the article noted that “The cabin is a comfortable place for five occupants to spend time, boasting sumptuous seats, genuine wood trim and high levels of fit and finish.”

Those of you who are concerned with safety, don’t be. After all, this is a Mercedes-Benz. They wrote, “Mercedes-Benz has long been known for its safety features, and the E350 BlueTEC will only add to that reputation. In addition to ABS and ESP stability control, the car boasts nine supplemental restraints including two-stage front air bags, a knee air bag for the driver and pelvic air bags which work together with curtain and side air bags to provide extra protection for front occupants in dangerous side-impact collisions.” Other standard features include an Attention Assist system that alerts the driver when he is beginning to get drowsy.

Leftlane concludes by mentioning that the E350 is the only diesel-powered sedan in the luxury midsize category. Readers who are interested in similar economy could research the Infiniti M Hybrid or the Lincoln MKZ Hybrid.

MotorTrend – 2012 Mercedes-Benz E-Class E350 BLUETEC Sedan

MotorTrend pointed out the new features of the car in their most recent overview: “The 2012 Mercedes-Benz E-Class receives a few minor revisions mostly to the interior, including a new and redesigned steering wheel, a color instrument display panel, and a media interface that is relocated to the center console. LED daytime running lamps are now standard on all E-Class models. Non-AMG variants are fitted with a new, more fuel-efficient, seven-speed automatic transmission.”

In their review of the E350 the previous year, MotorTrend wrote: “The E350 Bluetec is not a blast to drive, period. In fact, the driving experience is actually quite dull.” They describe the acceleration as “lackluster” and the brakes and handling as “middle of the road.” But they add that the car is not intended to be a sport sedan and that the BlueTEC’s reason for being is its fuel economy. In nearly 900 miles of driving during their road test “the oil-burning Benz achieved an average of 26.8 mpg and needed a total of two fuel stops.” They also like that the diesel model is only $1500 more than the gas version.

Two other minor critiques were the “cheap-looking plastic pop-up door locks” and the fact that folding rear seats were optional instead of standard. They conclude by saying “Given its fuel economy and ability to effortlessly eat up highway miles, it would certainly make a great road-trip car.”

2012 Mercedes E350 BlueTEC Diesel Review Summary

In conclusion, the consensus appears to be:


  • fuel economy
  • effortless passing
  • highway driving
  • luxury interior
  • safety features
  • price and performance compared to the gas E350


  • Lackluster acceleration
  • Dull driving experience

  1. I purchase this car a month ago. It’s the best car I ever purchased. There are literally no compromises. It is stylish, fuel efficient ( I am averaging a combine 30 mpg) has ample get up and go. It’s 0 to 60 time is only .2 seconds slower than the gas powered e350. The only question I have is why did it take me so long to get one?
