DaimlerChrysler is proud of its BLUETEC diesel technology, and rightly so. The automaker is really the first to see the new diesel standards in the U.S. as an opportunity and not an obstacle, unveiling the Mercedes-Benz E320 BLUETEC last year. Three more models, the R-Class, M-Class and G-Class, are scheduled to get the 3.2L BLUETEC diesel engien by early 2008. The BLUETEC technology is so attractive that almost every German automaker selling cars in the U.S. has hopped on the BLUETEC bandwagon and will be selling the engines in the near future.

In an effort to keep the ball rolling, DCX today unveiled the Vision C220 BLUETEC concept, a version of the just-unveiled next-generation C-Class with a concept four-cylinder BLUETEC engine that produces 170 hp and 295 ft-lbs. of torque. In terms of fuel economy, it sips low-sulfur diesel at the rate of 5.5 liters for every 100 kilometers. In our wacky metrics, that equates to about 42.76 miles per gallon. Hybrid who? The engine uses all the latest diesel carbon and NOx reducing technology, including four valves per cylinder, a third-gen common rail direct injection system, a variable nozzle turbine turbo, exhaust gas recirculation. The BLUETEC bit adds an NOx storage catalytic converter with a patented onboard ammonia generation system that, ulike urea injection systems, requires no additives or regular check ups.

The Vision C220 BLUETEC is technically a concept, however, that will be on display at the Geneva Motor Show next week. While technically a production piece of hardware, we have to admit its numbers are very impressive.

PRESS RELEASE:

Mercedes-Benz unveils Vision C 220 BLUETEC in Geneva - First four-cylinder BLUETEC model: well on the way to complying with the EURO 6 emission standard
  • Extremely low emissions thanks to innovative emission control
  • Fuel consumption reduced even further to just 5.5 l/100 km
  • New C-Class awarded Environment Certificate by German TÜV

Stuttgart, Feb 26, 2007

Mercedes-Benz is unveiling its highly environmentally-compatible BLUETEC emission-control technology in combination with a consumption-optimised four-cylinder engine for the first time at the 2007 Geneva Motor Show. In terms of ensuring compliance with the even stricter EURO 6 emission standard, applicable to all new vehicles Europe-wide from 2015, the Vision C 220 BLUETEC shows the way ahead. Boasting an output of 125 kW (170 hp) and a peak torque of 400 Nm, the Vision C 220 BLUETEC now requires 5.5 litres of diesel per hundred kilometres, thanks largely to modified diesel engine technology and an intelligent system of energy management.
"The sophisticated four-cylinder diesel engine with BLUETEC emission control is a prime example of leading-edge, future-compatible technology," explains Dr Dieter Zetsche, Chairman of the Board of Management of DaimlerChrysler AG and Head of the Mercedes Car Group. "Our diesel strategy is an effective answer to the question of how to save fuel and, therefore, CO2, how to further reduce all exhaust emissions including NOx and yet still ensure effortlessly superior driving enjoyment. In this respect, we believe our state-of-the-art diesel concept is currently the best and most efficient solution available."

With the Vision C 220 BLUETEC, Mercedes-Benz is providing a taste of things to come as part of its BLUETEC initiative which was launched in the US last autumn. The initial impetus came from the market launch of the E 320 BLUETEC in North America in October 2006, which was timed to coincide with the introduction of low-sulphur diesel in that part of the world. A fuel consumption figure of 6.7 litres per hundred kilometres makes the E 320 BLUETEC one of the most economical vehicles in its class in the US.

With the first four-cylinder BLUETEC model, Mercedes-Benz illustrates just how versatile this innovative technology can be. Following the US launch, the company will also introduce BLUETEC in other markets. The technology is currently being adapted to European market requirements and further Mercedes Benz models, the aim being to also offer BLUETEC in passenger cars for European customers, starting in 2008.

BLUETEC – high-tech for the cleanest diesels in the world

BLUETEC is a DaimlerChrysler-developed technology designed to reduce diesel vehicle emissions, especially nitrogen oxides – the only exhaust-gas constituents that are still higher in today's diesel engines than they are in their petrol counterparts due to the principle involved. Mercedes-Benz is working intensively to optimise its engines and their combustion processes so as to minimise the nitrogen oxides before they are actually produced. In terms of "hardware", the sophisticated four-cylinder powerplant in the Vision C 220 BLUETEC, like the standard-production engines, includes four valves per cylinder, third-generation common-rail direct injection, a turbocharger with a variable nozzle turbine and exhaust gas recirculation. A highly sensitive electronic engine management unit reacts precisely to an extremely wide range of operating conditions and, in so doing, optimises the combustion processes.

The BLUETEC technology in the Vision C 220 BLUETEC still includes an oxidising catalytic converter, which reduces emissions of carbon monoxide (CO) and unburned hydrocarbons (HC), as well as a particulate filter. A modified NOx storage catalytic converter with a substantially extended service life, including patented on-board ammonia generation, is combined with an additional SCR catalytic converter to minimise nitrogen oxides. This process of exhaust-gas aftertreatment requires no additives.

Vision C 220 BLUETEC combines environmental awareness, driving enjoyment and comfort

The results are impressive whichever way you look at them: on the one hand, the concept car equipped with a 6-speed manual transmission consumes just 5.5 litres of diesel per hundred kilometres (NEDC); on the other hand, it delivers the same impressive output and torque figures whilst providing a unique combination of efficiency and driving enjoyment. The Vision C 220 BLUETEC is prepared for future emission standards, even the considerably more stringent limits imposed by EURO 6, which will apply to all new vehicles from September 1, 2015. For instance, particulate emissions must be reduced by a factor of five by the time the EURO 5 standard comes into force on January 1, 2011 whilst EURO 6 stipulates nitrogen oxide limits that are only around 30 percent of the current limits. All Mercedes-Benz diesel vehicles with a particulate filter fitted as standard already undercut the particulate limits that will apply from 2011 onwards

For the US market, Mercedes-Benz will be offering three further V6 BLUETEC models – R Class, M-Class and GL-Class – with BIN-5 certification for all 50 states from as early as 2008. At the Detroit Auto Show in early January, the Stuttgart-based manufacturer demonstrated just how suitable the clean, economical, high torque engines are for large cars and SUVs: the V8 diesel engine in the Vision GL 420 BLUETEC that was on display at the show has an output of 216 kW/290 hp, a peak torque of 700 Nm and an expected fuel consumption of just 9.8 litres per hundred kilometres.

New C-Class: CO2 emissions already reduced by 15 percent

The standard-production version of the new C-Class, which celebrates its premiere at the Geneva Motor Show, is testament to the successful work performed by Mercedes-Benz in its quest to consistently reduce both fuel consumption and emissions. A lifecycle assessment carried out on the new Saloon, certified by the German technical inspection authorities (TÜV), confirms that the carbon dioxide (CO2) emissions for what is now the fourth-generation C-Class have been reduced by 15 percent.

By way of example, the experts who performed the lifecycle assessment calculated that the total energy requirement of the new C-Class is 125 gigajoules lower than that of the previous model, equivalent to around 3800 litres of fuel. Since the year 2000, the carbon dioxide emissions have fallen by nine tonnes (15 percent) per vehicle.

The reduction in exhaust-gas emissions is equally impressive: compared to the previous model produced in the year 2000, the sophisticated technology at the heart of the new C-Class cuts nitrogen oxide emissions by around 20 percent and hydrocarbons by twelve percent, according to the lifecycle assessment. Mean-while, particulate emissions from the diesel models have fallen by over 90 percent thanks to the fitting of a maintenance-free particulate filter as standard.

The new C-Class is the only car in the world in this market segment to have been awarded the Environment Certificate, thus underlining the Saloon's environmentally compatible product development.

      Very nice diesel. But the VW Jetta 2.0 TDI with 140 hp that will come next year will be more afordable, but nothing wrong with this diesel.
      • 7 Years Ago
      Won't that be exciting to be driving in your Mercedes and get dusted by a Honda Fit... This thing should have glacial accelaration.
      • 7 Years Ago
      Note: Both the C200 CDI & C220 CDI 2008 are using the same OM651 2.2L crd.
      Just that the C220 CDI uses the 170hp 400Nm/295lb-ft and the C200 CDI uses the 136hp 270Nm/199lb-ft

      Only the BlueTec will be offered in the C220 CDI, that I've seen so far as for media news releases.

      Lets see if I can answer or correct the above.
      1. "Definitly looking forward to the introduction of the C 220 Bluetec into the U.S.
      Too bad we have no diesel power for U.S.automobiles
      in the pipelines. Like the prospect of realizing 42.76 mpg in something that is larger than a Jetta or Beetle.Posted at 2:51PM on Feb 26th 2007 by Tal" Chrysler div in Erouope uses the same motor in the caliber, compass, patriot, sebring,& avenger. Hopefully they will wake up and bring them over from Europe now that VW paved the way.
      2. "#1 - I was under the impression the jeep liberty CRD was in the works for the US market...Posted at 4:45PM on Feb 26th 2007 by irony" Where were you? That came and went 2006 & 2005.
      3. "Won't that be exciting to be driving in your Mercedes and get dusted by a Honda Fit... This thing should have glacial accelaration.Posted at 5:16PM on Feb 26th 2007 by cheezwiz" http://www.subcompactcars.com/cars/jazz.htm 1.4L honda fit 0-62= 13.3 sec. Mercedes 2008 C200CDI (0-62mph)0-100km/h= 10.4 sec & C220CDI = 8.5 sec. From DCX media page. C320CDI 3.0L crd = 7.7 sec.
      4. "Maybe Ford should source the BlueTec to solve their PowerStroke problems! ;) #2, the Liberty can't get 42MPG. I know because I own one (and a VW TDI) and the Jeep does between 27 & 30 MPG.--chuck Posted at 5:17PM on Feb 26th 2007 by chuck goolsbee"
      BlueTec is the exhaust system with filters and urea injection. Ford is always ok to join in with the multi other companies that want to use the urea injection exhaust system. As for liberty fuel mileage http://www.fueleconomy.gov/feg/bymodel/2006_Jeep_Liberty.shtml is all I can say.

      cheezwiz:
      You may be able dust a Mercedes C-class (arguable)but at the end of the day you're still driving a Honda Fit.
      • 7 Years Ago
      #3 - a much heavier E320 CDI with only 40hp more does 0-100 in well under 7 seconds, so I doubt it will be slow.
      • 7 Years Ago
      The Mercedes OM 651 2.2L replaces the OM 646 2.2L.
      Plus for chysler (depending on sale) replaces all VM 2.8Lcrd's.
      There is a little over lap between the new lower output 3.0L crd and the high output 2.2L. Both motors to replace the 2.7L crd I-5. Like in the E280CDI & E220CDI.
      E280CDI & E320CDI both use the same 3.0Lcrd but at different power levels.

      #1 - I was under the impression the jeep liberty CRD was in the works for the US market...

      ' Won't that be exciting to be driving in your Mercedes and get dusted by a Honda Fit... This thing should have glacial accelaration.
      '

      Nearly 300 ft/lbs of torque and you predict glacial acceleration?
      • 7 Years Ago
      Maybe Ford should source the BlueTec to solve their PowerStroke problems! ;)

      #2, the Liberty can't get 42MPG. I know because I own one (and a VW TDI) and the Jeep does between 27 & 30 MPG.

      Do not buy these cars. I own a MB and it has been the worst car I ever had. Thinking luxury and top the line automobiles? MB are not. As matter fact they are the worse. I could not believe it my self. The safety standars in Canada are more strict. Cars have to pass a safety check that requires more frame work as well bumper test. these cars do not pass. In the USA they do pass becuase in the USA their laws protect business and not individuals when it comes to safety. Go ahead an buy this car and try to cross the border with, or better off before buying ask a Canadian MB dealer if you can bring the best car this planet MB from the USA, they will tell you flat NO. It does not meet safety canadian safety standards, but the worst is that the car can not be modified to meet canadian safety Standards. what a rip off!!!
