VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx

VW’s ultra-low emission Jetta BlueTDI will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.

This newer version of the Jetta will meet the strictest emissions standards in the world—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).

There’s been talk about the VW 1L concept for years. Since VW built the original, fuel economy, safety, price, and release date has been speculated upon and argued about, and I’d finally stopped thinking it was ever going to happen. However, according to VW’s CEO, it should hit the market in 2010.

The VW 1L is so named because, in theory, it only consumes one liter of fuel per 100 kilometers traveled. For those of us in the US, this translates into about 235 MPG. Definitely far and above anything on the market currently. The concept, developed in 2002, actually got better fuel economy, scoring a sweet .89L/100km in VW testing. It’s likely to use more fuel in real world use, but with that kind of mileage in testing it’s unlikely that anyone would complain about an “unsatisfactory 200 MPG.”

As has happened before, with gas prices continuing to climb, the demand for improved fuel economy will increase as well, and all manner of improvements and upgrades that promise to help get better mileage will be touted. Some offer real benefits; others are pure snake oil.

An improvement that offers both improved mileage and increased horsepower seems counterintuitive at first. After all, the tradeoff that hybrids and other economy vehicles offer seem to be one of reduced horsepower and acceleration in exchange for improved fuel economy. So how can you have both?

As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.

These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.

More on the six new engine technologies after the break.

The White House has outlined their plan to increase fuel efficiency standards to 35 MPG by 2020, a move that will save Americans an estimated $100 billion in fuel costs.

The mandate was outlined in last year’s energy bill in December, but this proposal gives a boost to the timeline by requiring the mileage of passenger vehicles to average 31.6 MPG by 2015. That’s up from today’s average of 25 MPG (which I can’t help but mentioning is identical to the mileage of the original Model T Ford). Read the rest of this entry »

How much gas money would you save if you didn’t have to make a lot of left turns?

UPS, the delivery people, decided to re-structure the delivery routes taken by drivers to eliminate as many left turns as possible. Now that may sound weird, but how long have you sat in a left turn lane waiting for oncoming traffic to pass, and how many times have you dreaded crossing into oncoming traffic?

The results have been dramatic. UPS says its 95,000 vehicles shaved nearly 30 million miles off its deliveries in 2007, saving the cost of 3 million gallons of gasoline and reducing truck emissions by 32,000 metric tons.

Makes sense to me. Sally and I both plan our drives with right-hand turns in mind, rarely adding an inch to the overall length of the drive, and feeling a lot safer.

Just to mix things up a bit, take a look at this car from the 2008 Eco-Marathon, registering at a whopping 7,148 MPG (via Autopia):

Looking like one of those space caskets from Star Trek, the single-seat racer you see to the left, constructed by a team from the French technical school St. Joseph La Joliverie and dubbed the Microjoule, traveled an amazing 7,148 miles on a single gallon of fuel (in other words, almost ten miles per teaspoon).

Imagine if you could eke more mileage out of your Prius. If you’re like me, you’ve already tried. What if you could get a decadent 100mpg? More? A group of Prius owners in Japan are doing just that - by hacking their Priuses.

According to this CNN report, the record holder among an underground group called “Mileage Maniacs” (Japanese language only) has managed to travel 1500 miles on a single tank of gas. That’s about 116mpg; I’m green with envy! Fortunately there is a similar push in the USA and Canada to feed the demand for more efficient cars. Numerous easter eggs , and hacks are available so an enterprising Prius owner can get more mileage. There’s even a solar company and those who will modify your car into an hybrid plug-in. Some plug-ins are already on the road. Voided warranty aside, extensive green modifications require a lot of green from the owner, ranging from a $40 kit to thousands of dollars.

Run your car on compressed air? Drivers in Europe may be doing just that by the end of the year, according to a report from the BBC…

Since last year, many of us have been eagerly awaiting the introduction of ‘clean-diesels’: the 2008-2009 models touted as having superior mileage and cleaner emissions than comparable gas models.

So where are they? Strangely, promised 2008 models didn’t materialize, and I had trouble finding more on the story. As far as I can tell, we’ll just have to look forward to next summer’s release of the 2009 VW Jetta TDI. The new Jetta gets similar mileage to older models, 50 mpg ( though VW engineers claim 30% better mileage under real world conditions). More importantly though, it’s the first diesel to meet the world’s toughest emissions standards, California’s Tier II, bin 5, earning it clean-diesel status. If you noticed the recent lack of diesel vehicles for sale (especially in CA), it was the direct result of reengineering emissions systems:

Although it won’t be wearing the “BlueTec” badge, the Jetta will be using emission-cleansing technologies developed under the cooperative formed by Audi, Mercedes-Benz and Volkswagen to make it 50-state legal. Most BlueTec vehicles control NOx emissions—one of the biggest environmental hurdles facing diesels, along with particulate matter—by injecting a urea-based solution into the exhaust system upstream from the catalytic converter, where NOx is then converted into nitrogen and water. The Jetta will instead use a NOx-storage catalyst, which is basically a reservoir that temporarily holds the noxious emissions, like a particulate filter, until they can be burned off during one of the engine cycles.
