Hot on the heels of the announcement that Mercedes will produce electric cars, comes the news that fellow German manufacturer Volkswagen plans to produce a test fleet of plug-in hybrid electric cars by 2010.

A few months ago, to much excitement from the automotive press, the company unveiled a diesel-electric Golf but, according to VW chief Martin Winterkorn, “the future belongs to electric cars.” To help in mapping out the road to this electric future, the company have unveiled a plug-in hybrid powertrain, called the Twin-Drive, which will make its first appearance in a Golf kitted out with a 122-horsepower diesel engine, twinned with an 82-horsepower electric motor.

2009 Jetta TDI Clean Diesel Sedan

VW announced the pricing of the 2009 Jetta and SportWagen yesterday, along with a new fuel economy certification from the third-party certifier AMCI. It seems that VW wasn’t particularly impressed with the EPA’s 29 mpg city / 40 mpg hwy estimation, and wanted a second opinion.

There has been some general confusion circulating about fuel economy estimates for the new Jetta (which will be available in August) ever since VW’s Director of Powertrain Development announced the car could get up to 60 mpg.

Tiguan HyMotion Fuel Cell Concept Car

Last Thursday I had the opportunity to attend a VW press event showing off the new hydrogen fuel cell powered Tiguan. The vehicle (above) is one of only two concept prototypes in the world, and this one was flown in from Germany for its US debut.

The event was originally intended to be a test-drive of the HyMotion Tiguan, but the vehicle was having “electrical problems” that kept it out for display only. A VW spokesperson assured us that it had nothing to do with the fuel cell, but whatever the problem was they didn’t want it to happen to us in mid-day San Francisco traffic.

Toyota Prius sales have topped 1 million and dealers in most markets simply can’t keep them on the shelves. Toyota says domestic inventory is limited by production capacity in Japan, which is shared by the Asian and European markets. The U.S. supply is at its lowest level in two years (Wired).

Imagine a high-speed train that could get you from San Francisco to Los Angeles in two hours forty minutes. Well, that dream is now one step closer to reality as the California High Speed Rail Authority has cleared environmental impact assessments and is beginning construction of what will be the most substantial high-speed rail network in the U.S. But don’t make travel arrangements just yet. The project is not scheduled to be completed until 2030 (gas 2.0).

A joint biofuel effort was announced Thursday involving Air Bus, JetBlue, Honeywell, and Aero Engines that plans to study ways to make commercial aviation fuels out of second-generation feedstocks such as algae (Green Tech Blog).

A new wave of nuclear power plants in the U.S. is likely to cost $5 billion to $12 billion a plant, two to four times previous estimates, driving up electricity bills for consumers and inevitably reigniting public concerns about the costs and benefits of nuclear power (The Wall St. Journal).

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

VW’s ultra-low emission 2009 Jetta 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).

Mercedes is billing the E320 BLUETEC as the “cleanest diesel vehicle in the world.” Engineers incorporated a modular design concept which uses a series of components, such as an oxidation catalytic converter and a maintenance-free particulate filter, to “wash” emissions from the engine before anything leaves the tailpipe. Those features, combined with an advanced new approach to reducing nitrogen oxide emissions, make the BLUETEC’s emissions cleaner than even a standard gasoline automobile.

The BLUETEC also offers a combined 36 mpg (700 miles per tank), all the luxury Mercedes is known for, and a 208 horsepower V-6 engine that goes 0-60 in 6.6 seconds. Not bad. The last diesel vehicle I owned went 0-60 in about 6.6 minutes when the turbo still worked and with wind pushing it down a steep hill.

Though the BLUETEC’s new diesel engine technology greatly reduces emissions, Mercedes still only approves the use of B5 (5% biodiesel/95% dino-diesel) in its diesel vehicles. Unfortunately, this effectively means that Mercedes doesn’t approve of the use of biodiesel. By the time next year’s World Green Car contest rolls around, it would be a thrill to see Mercedes and other car manufacturers embrace existing and available renewable fuels along with their commitment to reducing tailpipe emissions. (If you missed Clayton’s excellent “Green Myth Busting” post on biodiesel, be sure to check it out.)

To be eligible for the World Green Car prize, vehicles must:

• Be available to the public now or in the near future, and

• Meet or exceed the requirements of California’s SULEV (Super Ultra Low Emission Vehicle) regulations or the US EPA’s Tier 2 standards, or

• Get at least 47.6 mpg, or

• Use advanced technology aimed at increasing the vehicle’s environmental responsibility.

The E320 beat out two other finalists, the BMW Hydrogen 7 and the 60+ mpg diesel Volkswagen Polo BlueMotion, to claim the award.

Speaking of which, from my view here in the peanut gallery, it looks to like the World Green Car jurors may have chosen the wrong car! At least, they may have chosen the wrong diesel car. The E320 BLUETEC is a fantastic automobile, and a few dozen people in the U.S. might even be able to afford one ($52,000 for the base model). The VW Polo BlueMotion diesel, on the other hand, get 25 more miles per gallon than the E320 BLUETEC and has a very reasonable MSRP of under $20,000. Of course, the downside is that VW has yet to announce when the car will be available to US consumers, if ever.

Oh Lord, maybe you can buy me a Mercedes-Benz after all…
