Volkswagen finishes up Jetta BlueTDI development, on sale this summer
The new, fifty-state legal Jetta BlueTDI is finally done and it's coming soon. At the International Vienna Motor Symposium in Austria, Volkswagen announced that it's completed development on what they are calling the BlueTDI system for their US diesels. Like Mercedes (BlueTec) and BMW (BluePerformance), VW is adopting the Blue moniker for their cleanest, most efficient systems. The Jetta BlueTDI will be the first Tier2 Bin5 compliant diesels that doesn't have to use a urea injection system to meet the new NOx emissions standard. VW started with the updated 2.0L TDI that was launched in the European Tiguan last fall. Individual cylinder pressure sensors were added that allow the engine management system to optimize the fuel injection pulses to keep combustion temperatures down. That helped VW eliminate 60-percent of the NOx emissions before you even get to the exhaust stream. The exhaust gas flowing from the 2.0L engine are low enough that VW was able to use a lean NOx trap to convert the remaining NOx to nitrogen and water. However, the larger 3.0L V-6 TDI that is coming in the Touareg and Audi Q7 at the end of the year will have to use urea injection. In addition to the NOx trap, there is a particulate filter to eliminate the soot often associated with diesel engines. The new Jetta will be able to get up to 60mpg when cruising on the highway, a boost of 12-percent over the last US-market Jetta TDI from 2006. The Jetta BlueTDI should be the first of the new round of diesels to come to market when it arrives later this summer. The first batch of cars should actually start arriving at US dealers in June, where they will be available for test drives through the summer before going on sale in September.

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.

2) = MPG (miles per gallon) is the standard range specification in the U.S. for describing fuel consumption.

A hybrid gets better fuel economy in urban driving than a comparable diesel-powered vehicle does.
Also, Toyota quality is better than VW quality.

How 'bout a BlueRabbit? I'd totally try and make the numbers work to trade in my '07 Rabbit for a 60 MPG Rabbit.

Spots 7:32PM (4/24/2008)
Absolutely- the Rabbit's much better looking than the Jetta, and much more usable besides.
My only issue is that gas is about 60-90 cents a gallon cheaper (87 regular unleaded) than diesel in my area...
montoym 12:13AM (4/25/2008)
Well,when it gets almost twice the HWY mileage of most cars in its class, I think I can make 60-90 cents work for me. That's not twice the price/gallon.
asurroca 1:11AM (4/25/2008)
Spots... The TDIs get nearly twice the fuel economy of comparable gas models. My Beetle gets 42 MPG in-city (aggressive driving to boot) and I'm pretty sure the gas Beetle's don't get more than 24 MPG in-city. Sure, regular is about $3.60 around here and I just filled up with diesel at $4.15. With these numbers as an example, it's costing about $0.15/mile for a gas Beetle and $0.10/mile for a diesel one. For my diesel to cease being cost-effective, gasoline would have to cost like $3/gal LESS than diesel...
why not the LS2LS7? 1:22AM (4/25/2008)
No, your Beetle doesn't get 42mpg (at least not US gallons) in the city with aggressive driving.
Spots 5:25AM (4/25/2008)
But it doesn't get twice the gas mileage of my current daily driver- granted, it's much more car than I drive now-a '99 Metro 3 banger that even with 177k miles on it (120 miles a day round trip commute), still gets 46 mpg- nearly 100% highway. Not sure an extra 13 mpg would be worth an extra 80 cents per gallon...
Eric 4:47PM (4/25/2008)
@why not the LS2LS7?: My buddy's older Jetta TDI gets 40 mpg in the city, with the air conditioning cranking all the time. So I certainly don't doubt this guy's TDI Beetle gets 42 mpg city...
Razor 6:01PM (4/28/2008)
@Spots
Dude it's a 99 Metro, not only would it be worth the 80 cents but I'll raise you 25 on top of it...
Bill Montgomery 7:28PM (4/24/2008)
60 MPG!!!! EXCELLENT, and some actual torque/power in a normal decent looking sedan - imagine that. Glad to see someone can come out with something that gets incredible MPG and not look like a toy wedge. I'm heading to my VW dealer now to put down a deposit.

You shouldn't have any problem, the order books have been opened for a while.

Well look at it this way, while the fill up may be more expensive. you will go almost double the distance before you have to fill up again. on a similar size tank.

If VW made a 140HP gas motored car with the other fuel-sipping features of this car, it wouldn't be nearly such a large gap.
Chase 9:10PM (4/24/2008)
As a matter of fact, the VW 1.4L "Twincharged" TSI makes 170hp, and delivers 28/50 mpg

Because of emission standards diesel engines are very optimized. I don't know if they even make non turbo diesel. One reason why I haven't jump on the diesel bandwagon is that its not a fair comparison to gasoline engine. I want to see numbers of a comparable twin turbo charged gasoline engine maximized for mileage. I am inclined to think that kind of engine would come very close to diesel engine. Come on, a yaris with no turbo engine gets 40 mpg. Imagined a twin turbo on with less displacement. Certainly it will be cheaper dollar/mile and with none of the emission restrictions.

How does a trap turn nitrogen and oxygen into water and nitrogen? Doesn't this require a source of hydrogen?
