At the International Vienna Motor Symposium, which starts today, Volkswagen is announcing that its next-generation turbo diesel engine, BlueTDI - developed especially for the North American market - will initially be available in the U.S. version of the Jetta. The Jetta BlueTDI will come to North America sometime in the middle of this year, followed at some point by the Touareg BlueTDI.

BlueTDI is the cleaner version of the already pretty clean TDI engine that VW uses in its European diesels (starting with the Tiguan last year). TDI meets the Euro-5 standard and BlueTDI is ready for the stricter Bin 5, Level 2 standards that are in force in five U.S. states, including California. Not only does the BlueTDI engine have the low emissions, but VW's director of powertrain development, Dr. Ing. Jens Hadler, said in a statement that the Jetta BlueTDI can get up to 60 mpg in highway driving. Perhaps that'll ease the pain of the Golf TDI hybrid's failure to launch. The BlueTDI displaces 2.0 liters and generates 103 kW/140 PS with 320 Nm of torque. More details after the break.

Press Release:

Vienna Motor Symposium 2008: BlueTDI development completed successfully
BlueTDI will debut midyear in North America

The U.S. version of the Jetta will be the first to use BlueTDI
Wolfsburg, 24 April 2008 - At the International Vienna Motor Symposium (24-25 April), Volkswagen is to introduce the production version of the BlueTDI, a next-generation turbo diesel developed especially for the North American market. The common rail engine is based on the high-tech TDI, which was first introduced in Europe in 2007 with the Tiguan. This engine already satisfies the Euro-5 standard that comes into effect in autumn 2009. In order to meet specific operating conditions in the U.S., this four-cylinder engine was redeveloped with internal engine modifications and a NOx trap.

Background information: Five U.S. states1, including California, currently have the strictest emissions standards in the world (BIN5/LEV2). In spite of variations in fuel quality, which are more dramatic in the U.S. than in Europe, the new BlueTDI meets these emissions standards. The engine will debut in the U.S. Jetta this summer. For years, the Limousine has been the most popular and successful European-manufactured car on the American market, especially as a diesel.

The Jetta BlueTDI will debut as one of the cleanest and most economic cars of its class in the world. In the run-up to the Vienna Motor Symposium, Dr. Ing. Jens Hadler, Director of Volkswagen Powertrain Development comments, "high fuel prices and a dramatic change in environmental consciousness means that diesel is becoming more and more attractive for American drivers every day." Dr. Hadler continues, remarking, "this is why many customers, especially in California, have been waiting for a super-clean diesel like our BlueTDI. I think this motor will help the diesel get its big break in America because it consumes so little and yet can go such long distances on a single fill-up. And in a country as big as the United States, this is a priceless advantage. On the highway, for example, this engine can reach up to 60 miles per gallon2. This is an improvement of 12 percent over its predecessor, which had a lower capacity and higher emissions."

A key aspect in the development of the BlueTDI (2.0 litre engine displacement, 103 kW/140 PS, 320 Nm) was the reduction of nitrogen oxide emissions (NOx); the American BIN5/LEV2 standards stipulate a nitrogen oxide limit of only 0.05 g/mile. The engineers in Wolfsburg met this limit and the general reduction of raw emissions by using internal engine modifications, some of which are unique worldwide, and implementing the maintenance-free NOx trap.

These internal engine changes include modifications to the design of the injection system of both the American and European TDI as well as the implementation of cylinder pressure sensors. This allows for a completely new type of cylinder pressure-based combustion control, which is both faster and tailored to each specific cylinder. Also new on-board: an optimised high-pressure injection pump. Another unique feature is the combination of a high-pressure exhaust gas recirculation system with additional low-pressure exhaust gas recirculation. This dual exhaust gas recirculation (dual circuit EGR) is an effective means of reducing nitrogen oxides in the engine. The dual circuit EGR system alone reduces NOx by up to 60 percent.

Outside of the engine, it is the NOx trap – connected downstream of the oxidation catalytic converter and the particle filter – that reduces nitrogen oxide to an absolute minimum. Implemented together, these measures reduce nitrogen oxide emissions by 90 percent. Drive the Jetta BlueTDI and you will be driving one of the most economical and environmentally-friendly cars in America.

1) = BIN5 states: California, Massachusetts, Maine, New York and Vermont.
2) = MPG (miles per gallon) is the standard range specification in the U.S. for describing fuel consumption.


I doubt you can use homebrew bio and definitely not veg - I'm sure the cats will get clogged and set a " $150 at the dealer " check engine light.

uh oh, MB sues over Bluetec...I hope this doesn't prevent the cars from coming

Back in November 2006, Mercedes-Benz, VW/Audi and BMW indicated that the three companies would be cooperating on promoting new clean diesels using the same BlueTec aftertreatment technology. Within a few weeks BMW and, later, Volkswagen made it clear they would not be using the BlueTec branding on their cars. BMW chose to call their system BluePerformance and Volkswagen and Audi are using CleanTDI or simply TDI. Nonetheless all three manufacturers are using the same technology in order to meet U.S. Tier2 Bin5 emissions requirements. All the engines use high-pressure common-rail fuel injection systems along with diesel particulate filters and urea injection systems to eliminate the soot and NOx emissions. The only exception is Volkswagen's smaller 2.0L four cylinder diesel which will use a maintenance-free lean NOx trap in place of urea injection.

As the three manufacturers race to get their first clean diesels to the U.S. market this fall it looks like Mercedes may be filing a patent infringement suit against Audi over the BlueTec technology. It appears that under the original alliance Daimler may have wanted a licensing fee from BMW and VW/Audi. Mercedes has a European patent (EP1054722B1) that apparently covers some aspect of the NOx reduction. It's not known at this point exactly what the patent covers because the after-treatment systems are actually provided by suppliers like Bosch and Delphi. At this point it sounds like a lot of spite and it's anyones guess if this will affect the U.S. launch of the new diesels.

They'll be here, it's too late to stop! [crosses fingers]

did anyone else see this? It adds some value to the buy.

AUBURN HILLS, Michigan — Volkswagen's U.S. arm on Wednesday said it would offer free scheduled maintenance on its 2009 lineup, starting with its new Tiguan. The move is designed to further differentiate the German automaker from its competitors.

"Volkswagen's Carefree Maintenance Program is a great way to improve our owner loyalty for our brand, as well as increase consumer consideration," said Mark Barnes, VW of America chief operating officer.

The program covers maintenance at 10,000-mile, 20,000-mile and 30,000-mile intervals. The automaker said that because all current VWs use synthetic oil, a 5,000-mile checkup is no longer necessary.
