BlueTEC with AdBlue for 2009 GL320, ML320, & R320

Besides seeing the 2009 SL for the first time today, our training included a lot of information about the 2009 ML320, GL320 and R320. For 2009 the CDI diesels that currently power these SUVs will be upgraded with BlueTEC emission systems similar to those in the current E320 BlueTEC. These vehicles will also be the first to use AdBlue to decrease emissions to levels that will allow them to be sold in all 50 states. (AdBlue isn’t expected on the E-class until its redesign is released around August of 2009.)

AdBlue is a fluid that when combined with the exhaust gases results in a dramatic decrease in emissions. While diesel engines are already more efficient than gas engines, getting about 30% better fuel economy, their sales have been limited by emission standards in many states. Georgia is not one of these states but as the number of states that restrict diesels has grown it was important to find a solution. Check out the video below to learn more about how the injection of AdBlue into the exhaust reduces emissions.


The addition of the AdBlue system will result in a few changes to these vehicles. The biggest change will be the tank to store the AdBlue fluid. To elminate interior modifications this tank will occupy the space currently used for the spare tire. As a result, all 2009 BlueTEC SUVs will be equipped with run-flat tires. The non-diesel SUVs will continue to have spare tires.

The tank for the AdBlue will be between 7 and 9 gallons. The tank will be topped off at the regular 10,000 mile service intervals and completely flushed and refilled about every third time. You will get a service indicator alert if your AdBlue tank reaches 25% capacity. Then, if your tank runs empty, you will have 20 starts to either visit the dealership or top off the AdBlue tank yourself. The AdBlue fluid is supposed to be available in 1 liter bottles at many retailers by the time that you’re ready to refill.

I would be happy to talk diesels if you have any questions or would like to pre-order. We expect these vehicles to be released for sale on October 1st, 2008. As with all pre-release information this is subject to change, and change without notice.

Mercedes GL320 CDI – MotorWeek Review

Diesels are Clean and Green!

There was a great article at AOL Autos today about the advances that have been made in diesel technology. Maybe with enough good publicity everyone will come to understand diesel and love it as much as I do!

Highlights from the article…

“One automaker at the forefront of the clean-diesel movement is Mercedes-Benz. The E320 BLUETEC boasts 40 percent better fuel mileage than a comparable gasoline-powered model, and its EPA city/highway rating of 27/37 mpg means it can cruise more than 700 miles on a single tank of fuel, said Patrik Borenius, manager of advanced product planning for Mercedes.

With a city/highway rating of 21/28 mpg, the R320 CDI gets 32 percent better fuel economy, while the ML320 CDI sport utility (rated at 21/27 mpg) provides a 26 percent improvement. Both CDI models have a cruising range of over 600 miles before refueling.”The new clean-diesel engines provide three key benefits,” Borenius said. “It’s a more fuel-efficient technology, so the customer gets better gas mileage; it offers environmental benefits by producing less carbon dioxide and greenhouse gasses, and it’s one of the answers to the energy issue, in terms of reducing our dependence on foreign oil.”

In April, the E320 BLUETEC was named the “2007 World Green Car” at the 2007 New York International Auto Show.

Mercedes Vision GLK BLUETEC Hybrid – 40mpg!

At the Geneva auto show Mercedes-Benz showed off their new Vision GLK BLUETEC Hybrid. Based on the upcoming GLK-Class this concept combines a 2.2 liter BLUETEC diesel with a mild hybrid system to result in a stunning 40 mpg. The 2.2 liter diesel by itself is a great package with an output of 224 hp & 413 lb-ft of torque.

I’m a huge fan of diesels and I would love to see this motor with or without the hybrid in the GLK and next years C-Class for the US market. Based on Mercedes past launches I would expect to see the GLK BLUETEC available a few months after the gasoline powered GLK350 comes out this summer. The hybrid GLK will probably launch in 2009 or 2010 along with hybrid versions of several other Mercedes models.

Get in touch with me today to get on the list for the new GLK.

My Thanksgiving Roadtrip in the ML320 CDI

Wow! That was a whirlwind!

I drove my 2008 ML320 CDI demo to Pennsylvania and New York to visit friends and family for a few days last week. I put just over 2000 miles on the ML in 5 days and it performed like a champ! Average fuel economy was 25 mpg at 75 mph and an astonishing 28 mpg at 65 mph! I got about 600 miles per tank!

It can hold a lot too. It’s amazing how much two people can pack for 5 days! And we’ll pack up to do it again for Christmas in 3 weeks!

GL320 CDI – Car&Driver First Drive Review


“We averaged 24 mpg over a 160-mile mix of city and highway roads, and even with frequent excursions to the 4600-rpm redline it seemed hard to ever dip below 20 mpg”

2007 Mercedes-Benz E320 BLUETEC – Car and Driver – Road Test

E320 BLUETEC

“Our lead feet averaged 34 mpg on our trip, which included some city driving, and we were able to make the entire 650-mile journey on one tank.”

“The quiet and smooth Benz diesel got 31 mpg on my commute, an impressive number I’ve never achieved in a hybrid. “

E320 BLUETEC – Voted 2007 World Green Car of the Year

The World Car of the Year Awards has named the new E320 BLUETEC Diesel as the 2007 World Green Car of the Year. You can read the full press release here. Below are some portions of that release.

“Jurors felt that the Mercedes-Benz E320 Bluetec, which the company calls the
world’s cleanest diesel, deserves the award for its role in enabling a diesel
re-entry to the North American market, as well as for paving the way for
super-clean diesel technology around the world. BLUETEC is a modular concept
that utilizes several coordinated technical measures to minimize emissions
within the engine and also provide for effective exhaust gas treatment
downstream. The process involves consistently reducing all relevant emission
components to a minimum. The system includes an oxidation catalytic converter
and a particulate filter in addition to new techniques for reducing nitrogen
oxide emissions.

The top three contenders for the third annual
World Green Car in addition to the Mercedes-Benz E320 Bluetec were the BMW
Hydrogen 7 and the Volkswagen Polo BlueMotion.”
