Beijing - The longest diesel marathon of all times ended successfully in Beijing today. The 36 Mercedes-Benz E-Class cars, which left Paris on 21 October on a transcontinental rally covering about 14,000 kilometres, arrived safe and sound in the Chinese capital after traversing Europe and Asia. Through this endurance test under extreme conditions Mercedes-Benz has once again dem-onstrated the outstanding performance of its modern diesel engines in terms of emissions, fuel economy and reliability. Proof of this is also the fuel consumption of the victorious “eBay” team which won the fuel economy contest with an average of 7.19 l/100 km diesel. The best result on a daily leg was as low as 5.5 l/100 km.

”During this endurance test of a total of more than 500,000 kilometres, the 33 E 320 CDI and three E 320 BLUETEC impressively showed the potential of our high-tech diesels . They proved that driving enjoyment, great fuel economy and environmental compatibility are not mutually exclusive” said Dr. Dieter Zetsche, Chairman of the Board of Management of DaimlerChrysler AG responsible for the Mercedes Car Group. ”At the same time, the long distance drive from Paris to Beijing rendered the qualities of the new E-Class generation more tangible. The E-Class has lived up to all the promises that we had previously made to the participants and our customers.“, he added. Today’s grand finale of the long distance drive took place at Beijing’s historic Yongding Gate, the southern access point to the “Holy Axis” of the Forbidden City.

During the five legs of the ”E-Class Experience" more than 360 drivers from 35 countries took turns at the steering wheels of the diesel sedans. In only 25 driving days they passed through nine countries under partly extreme conditions, such as snow and ice, as well as unpaved roads. The average daily driving distance was about 560 kilometres. Together with the 24 escort vehicles, which ranged from the G-Classes of the Mercedes-Benz crew and technical trucks to the mobile diesel service station, the marathon entourage covered a total road distance of about 840,000 kilometres. This corresponds to the 21-fold circumference of the earth at the equator.

Five legs from Europe to Asia

After the start in the shadow of the Eiffel Tower on 21 October, the route of the ”E-Class Experience” initially led through France, Germany, Poland and the Baltics to St. Petersburg, where the first change of drivers took place after seven days. In this case, the route followed the path of the legendary first transcontinental automobile race held 99 years ago, which ran in the opposite direction from Beijing to Paris and wrote automotive history.

The second group steered the E-Classes through Russia and over the snow-covered Urals to Yekaterinburg, while the third group drove through the hot, late-summer weather in the steppes of Kazakhstan to Almaty. The high-point of this leg of about 2,500 kilometres was the overnight stay with Kazakh guest families in the small town of Balchasch - organized by the local mayor.

In many places the convoy was spontaneously surrounded and joyfully greeted by local people who appreciated their striking and unusual design. All participating E-Class cars are decorated with the flags of the participating nations, in order to underline the international flair of the long distance drive.

Through the Taklamakan Desert onto the Silk Road

Nine days ago the diesel marathon crossed from Kazakhstan into our destination country, China, as the last of eight border crossings along the route. The final change of groups took place in Lanzhou on the Yellow River after crossing the Tak-lamakan Desert and driving about 1,000 kilometres on the legendary Silk Road. From there, the last 1,700 kilometres led to the south of the Gobi desert and through the grass steppes of Inner Mongolia. Yesterday evening the teams of the "E-Class Experience" spent their last night in Badaling at the Chinese Wall.

Record breaking consumption figures: 5.5 litres/100 km and 5,300 bananas

The "eBay” team in car number 3 won the fuel economy contest over the entire distance with a consumption of only 7,19 l/100 km. Thanks to their economical driving style, the ”German Taxi" team only needed 5.5 liters of diesel for every 100 kilometres on the 616 kilometre-long drive from Lanzhou to Wuhai. The figures are especially remarkable because all participating cars are standard production E-Classes with 165 kW/224 hp. And: the luxury sedans didn’t have it easy. They where fully loaded with up to three passengers and numerous pieces of luggage. Because of the anticipated bad road conditions and cold weather all cars were equipped with winter tyres and a suspension that was raised by five centimetres.

With a low total average consumption of 8.32 l/100 km diesel fuel for all 36 vehicles the goal of demonstrating the diesel engines’ superior fuel efficiency was clearly met on the individual legs as well as over the entire distance. In total the fleet of 36 vehicles consumed about 40,530 litres of low sulphur diesel fuel. That is about 20 percent or 10,000 liters less than originally estimated. The participating 18 rear-wheel drive vehicles consumed only 8.01 l/100 km diesel, while the 18 4MATIC models with four-wheel drive ended up with a slightly higher average of 8.53 l/100 km.

The 360 participants and 40-person support team had relatively higher consump-tion: In addition to breakfast and dinners, between Paris and Beijing they consumed about 8,200 lunch sandwiches, 5,300 bananas, 4,000 chocolate bars and 9,600 bottles of mineral water. All participants endured the strains of the marathon - apart from occasional upset stomachs - in good health, which luckily left the two-person physician team accompanying the entire tour with hardly anything to do.

Five fender benders but no dropouts

The 36 diesel sedans of the participants and the nine E 320 CDI of the crew proved to be both safe and reliable over the total covered distance of 640,000 E-Class kilometres. Despite the partly extreme road and traffic conditions there were no serious accidents, and only five fender benders occurred in traffic. Thanks to this, all cars which started in Paris reached their final destination in Beijing. The spare parts needed for the entire drive consisted of only three bumpers, two fenders, an alloy wheel, four windshields, and a rearlight. In addition the list mentions twelve electric bulbs, an alternator (following a courageous water passage away from the planned route) and 20 tyres, which were changed with breathtaking speed by the traveling Michelin service team. Otherwise, the technical crew had ”no special incidents” to report, except for two more figures for the statistics: a total engine oil consumption of just eight litres and the use of over 110 litres of screenwash fluid.

Extensive logistics behind the scenes

The success of the diesel-marathon depended on extensive logistics. As part of the preparations, nearly 5,000 hotel rooms in 27 cities had to be booked in advance, hundreds of visas obtained, flights booked and materials transported into the most remote of Russia, Kazakhstan and China. Even the diesel fuel for the fleet was distributed in advance among the stations along the route. The low-sulphur diesel needed for modern engines is not available on more than 10,000 kilometres of the route110,000 litres of "super-diesel" were allocated in daily rations and sent in con-tainers along the journey. The fuel for Russia was imported via Finland because of the simpler customs procedures, while the diesel for Kazakhstan travelled through Poland and Belarus. The containers for China were initially shipped to Shanghai, from where they were taken by trucks to the intermediate stations along the 5,000 kilometre long route through the Middle Kingdom.

The world’s cleanest diesel engines

The E-Class fleet that had started in Paris on 21 October comprised 36 series E-Class models with clean diesel engines, half of which are equipped with the all wheel drive 4MATIC. In addition to the 33 E 320 CDI, three E-Classes with BLUETEC went into the field. This new technology turns the Mercedes-Benz sedan into the cleanest diesel of the world. The E 320 BLUETEC has the first and only diesel engine worldwide that can outperform the current “BIN 8” US exhaust emission standard, particularly with respect to its nitrogen oxide emissions. The E 320 BLUETEC will initially be offered in the USA (in 45 states) and Canada and consumes up to 30 percent less fuel than comparable vehicles with petrol engines in North America. Thanks to its enormous range of up to 1,200 kilometres on one fuel tank it is the ideal car for a marathon such as Paris-Beijing, something of which the alternating drivers could personally convince themselves.

A taxi trip for 40,000 Euros

The most unusual vehicles in the fleet were the two E-Class taxi cabs which accom-panied the convoy over the total distance. In this case, the competitive comparison showed clear cost differences. The fare in the German taxi came to 16,050 Euros at the end of the fourth leg after just 12,000 kilometres. The trip in the Parisian taxi would have been clearly more expensive: At that point, the meter already displayed the proud amount of 34,090 Euros. Upon arrival in Beijing, the total had reached nearly 40,000 Euros.

Am I wrong but is 8l/km about 25mpg?

that sounds about right... 5.5 is like 45 ish mpg i think.

Hi Tom and Phil:

___I too read this and thought what a total waste. I don’t care if they were traveling down dirt roads, that FE was poor at best. To bad E-Bay or Google did not sponsor any one of us to run one of those Blutec’s just to see what they were really worth. At ~ 300 miles per day, 50 + mpg should be a cakewalk in any of them from my perspective.

___Good Luck

I don't understand why people see diesel and assume stellar mileage figures. A vehicle like this is comparable to a luxury hybrid, such as the GS450h, and it performs as one would expect it to under these conditions with ordinary drivers.

GS450h- 25/28mpg, 0-60 in 5.2s, kerb weight 4,134lbs
E320CDI- 27/37mpg, 0-60 in 6.8s, kerb weight 3,835lbs

What would be nice is an electric motor to augment the diesel engine and increase the city mileage significantly while cutting emissions drastically. But given the approximate $10,000 overhead and small, loyal consumer base, Mercedes probably felt it wasn't worth developing.

Hi Yesplease:

___Google the Audi V8 Turbo Diesel and Jeremy Clarkson. The vid’s are gone but his Top Gear vid showed that monster receiving over 42 mpg’s and > 800 mile range while running her at ~ 1,200 RPM or less. Again, not that stellar a FE result for most here but decent enough given the performance capability of the that full blown lux/performance machine. The European Honda iCDTi Accord’s (TSX’s here in the US) nailed down some nice 70 mpg - 200 + mile segments as a new car advertising gimmick when they were first released overseas. A CI-ICE is ~ 10% more efficient per gallon of diesel then a SI-ICE on gasoline at load. They are ~ 4X’s more efficient at idle as well. Add in another 10% for caloric content of the fuel and you have the makings for a really awesome FE monster. The E320 Blutech is a blistering 0 - 60 performer but when an everyday std. PZEV Accord w/ Auto can achieve 48 + year round, why did these MB E320 drivers have such low FE to show for the drives effort? A E320 has a Cd of just .27 which should make it one heck of a highway cruiser on top of a relatively efficient ICE! Add in the diesels high torque to pull tallish gears around town and bingo ...

___In any case, there is not a CleanMPG member here that could not drive that thing to 40 mpg + across any distance in their sleep let alone in a convoy of E320’s with a support crew like none we will ever have available to us in any past or future challenges.

___Good Luck

42mpIg is pretty good, but I don't think it's that much of a reach to think that the 18 RWD CDI's average of about 29mpUSg with 180 different drivers is unexpected. Not to downplay getting about 35mpUSg in a diesel A8, cruising below 1,200rpm the entire time, but it's just not the same situation. In any event, could've and would've, aren't. Why not procure a diesel A8 and find out? :)

Hi Yesplease:

___See the Accord’s lmpg below? It is EPA rated at just 24/34. Why are these CDI’s averaging just 29 mpg’s w/ an EPA of 27/37? Poor FE skills is the only way I can explain it?

___Good Luck

Compared to the style you drive, sure. But in the larger picture it's spot on compared to other vehicles listed on the fueleconomy.gov website. For example, most report that the 2005/2006 Prius gets about 10% lower than the combined EPA mileage, which about is what the RWD CDIs got. Not to knock your above average fuel economy, it's just that expecting others to have it (or do anything) will probably lead to dashed expectations. By poor FE skills are you referring to how the average person drives?

I'll avoid the main point of this debate, but would like to comment that the average urban American driver is a lead foot. It's so apparent it can't be characterized as highly subjective.

Hi Yesplease:

___When Honda released the 2.2L iCDTi, it was done with some fanfare. Let me bring you up to date wrt what Honda did with this diesel just before public release.

Honda Diesel Sets New World Records. (http://www.vtec.net/news/news-item?news_item_id=234399)

Honda’s new Accord 2.2 i-CTDi Sport has this week set no fewer than 19 world speed records and achieved 3.07 litres / 100 km (92 imperial mpg, ~76.6 US mpg) fuel economy to boot … Following the speed record attempts, the same two cars were then driven 419 miles from Papenburg test track to Wiesbaden, near Frankfurt in order to complete the fuel economy run. The route comprised of a mixture of motorway and non-motorway driving, during which one of the Accords achieved a staggering 92 imperial mpg (US mpg=~76.6) average.
___Receiving 10% under the EPA combined with the Blutec is absolutely pathetic. What was MB trying to prove? Someone could have driven a brand new Yugo 14,000 KM to China and received even better FE. If you are going to do a launch with a marathon, at least show us something. 29 mpg? Why bother given any number of brand new cars made today can travel 14,000 KM and receive that.

___With regards to the average persons skills, exactly ;)

___Good Luck

I don't think they were trying to prove anything. It was probably just brand exposure. It's not like wonderful fuel economy figures were expected during a cross continental drive involving 360 different drivers, 36 cars (3 Bluetecs), and 14,000km. According to the ECE fuel consumption (http://cars.rte.ie/newcars/index.cfm?fuseaction=details&passedcat=technical&vehicle_id=45313820060301), the RWD CDI should pull about 8.3L/100km. The best was 5.5L/100km according to the article, which translates roughly to a 36% decrease in fuel consumption.

The Accord i-CDTi (http://translate.google.com/translate?hl=en&sl=de&u=http://www.maxrev.de/honda-accord-diesel-i-ctdi-nur-3-07-liter-verbrauch-t154.htm&sa=X&oi=translate&resnum=5&ct=result&prev=/search%3Fq%3DHONDA%2Baccord%2Bdiesel%2B*l/100km%26hl%3Den%26hs%3DOwh%26lr%3D%26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DG) has a combined ECE fuel consumption of 5.4L/100km, and saw a minimum of 3.07L/100km, which roughly corresponds to a 43% decrease in fuel consumption. The difference being, the number and most likely experience of drivers, conditions, and distance, and possibly, Honda's underestimation of their own car.

Also the chief developer of the diesel engine Kenichi Nagahiro was surprised by the results. It had neither expected that an average maximum speed of more than 207 km/h was possible, nor that a consumption of under 5 litres on 100 km be achieved could. It had to state with a smile that it had underestimated its own engine.

The Honda and Mercedes events took place during very different conditions. If both companies had say, shown up on the same day, at the same track, to run the same fuel economy trials, at the same time, then I could see stating the Mercedes was pathetic if it returned those numbers seen on the trip while the Honda returned those numbers seen on the tests. But that wasn't the case. I'd wager that the Honda wouldn't have fared as well if it was being driven by 36 different drivers across a couple continents, instead of through Germany driven by a racing car driver. And the same goes for the Mercedes... Unless the conditions are the same I don't see how anyone can make a serious comparison. :confused:

Hi Yesplease:

___It is not about a comparison, it is about the show. MB performed there Marathon and the result was 29 mpg’s. Big deal. The press received from it is quite literally non-existent. The reason why is nothing spectacular was achieved. This is the key. When Honda punched out their numbers prior to the releases of the 2.2L iCDTi, the US based hybrid and non-hybrid boards around the net lit up like a Christmas tree and there was no way we were ever going to receive it. 76 mpg’s right after all the speed world records says Wow. 29 mpg’s driving 14K KM in a brand new $52,000 car means nothing other then this was a joy ride and the drivers FE skills were pathetic.

___That being said, would you prefer to purchase and own a 2007 - $52,000 MB 320CDI that receives on average 29 mpg (according to MB marathon) and a Fed emissions rating of Tier II/Bin8 (sorry Clean States, I cannot be sold there) or would you prefer to own a 2009 - $28,000 Honda Accord/TSX/Civic EX-L w/ NAVI w/ the 2.2L iCDTi that can receive upwards of 70 + (this was achieved) and also meets every states Emissions rating including the Federal Tier II/Bin5 and the Clean States LEV-2?

___Good Luck

I think Wayne is asking why more fuel efficient diesels were running.

I'm not up to speed on diesels, but a VW TDI get 50mpg?

I doubt this diesel (http://www.compositesnews.com/cni.asp?ArticleID=10837) could run that route, but it seems something is out there that could do a little better than the TDI.

I'm not, not diesel-bashing - just wondering why they did not offer more fuel efficient entries.

From what I've read , they're trying to expand in China's market, so for a PR stunt they need to show their cars are reliable (long journey), luxurious, relatively economical, and most importantly, the people's car. Especially since they've received a bit of negative publicity (http://www.chinadaily.com.cn/en/doc/2004-01/13/content_298371.htm), and want to expand (http://www.chinadaily.com.cn/english/doc/2004-07/12/content_347597.htm) in a luxury market where the only competition is BMW and Volvo.

"During this endurance test for a total of more than 500,000 kilometres, the 33 E 320 CDI and three E 320 BLUETEC impressively showed the potential of our high-tech diesels. They proved that driving enjoyment, great fuel economy and environmental compatibility are not mutually exclusive" said Dr. Dieter Zetsche, Chairman of the Board of Management of DaimlerChrysler AG responsible for the Mercedes Car Group. "At the same time, the long distance drive from Paris to Beijing rendered the qualities of the new E-Class generation more tangible.

Today's grand finale of the long distance drive took place at Beijing's historic Yongding Gate, the southern access point to the "Holy Axis" of the Forbidden City.

I suppose they could've brought in one of their smaller vehicles that averages closer to 5-6L/100km, but it might have been seen as insult to bring less than their best. So... it's not exactly a fuel economy run. Otoh, Honda's test was specifically about performance and fuel economy, since they're trying to break into a tight Euro market with their first diesel offering. Both companies felt they needed to show different things to different people.

On the flip side, I'd hate to see what these people have to say about anyone's mileage here.

Receiving anything less than infinite miles per gallon is probably pathetic from those POVs. ;)

On a side note, I'd love to see microcars in the states, but most people there tend to have this notion that smaller equivocates with poor quality because most of their experience with small vehicles is centered around low cost, bargain basement autos. I'd look into a well built 1L car if it was offered. But then again, I'd also like one of those little 600cc 4x4 trucks from Japan to tool around in. :)
