diesel

Mercedes-Benz has gotten a lot of press recently about AdBlue, the additive that makes its new BlueTec clean diesel SUVs and wagons so clean. I called up Larkin Hill, a PR rep at Mercedes, and asked her to explain to me what this AdBlue and BlueTec stuff was all about.

“Twenty years ago, 80% of Mercedes sales were diesel,” said Hill. “But they had a reputation for being loud, slow, and sooty. The BlueTec diesels are quiet, fast, and clean. You can stand behind one in a white linen suit and not get dirty.” This, she said, is due to AdBlue, an exhaust treatment fluid used in all the BlueTec diesels to neutralize nitrous oxide emissions.

In order for the Mercedes BlueTec diesels to meet the U.S. Bin 5 emissions standard, the company had to guarantee that the customer would put AdBlue into the exhaust system. “You get many, many, many warnings,” said Hill. “The car gives you twenty chances. It counts down the number of starts you have left.” When you’re out of AdBlue and the countdown reaches zero, you can’t start the car without adding another quart.

The reservoir is easy to find and easy to fill, though, as it’s located in the spare tire well in the back. And you can go 10,000 miles of normal driving without worry. Most people will have their M-B dealer top off the AdBlue tank during regular maintenance. For those who do a lot of towing or want peace of mind, BlueTec owners can buy and carry extra quarts. It’s available at 1500 outlets, like Pep Boys.

Right now, there are three 2009 vehicles with BlueTec clean diesel: the ML320, the GL320, and the R320. Hill said the company plans to release an E320 sedan with BlueTec and AdBlue later this year. And yes, she said, AdBlue is indeed blue.

The Environmental Protection Agency recently finalized its list of the top low-mpg cars for the upcoming model year. It doesn’t restrict itself to merely small cars or green cars with hybrid systems or alternative fuels, oh no. The EPA lists the most fuel-efficient cars, from minicompacts, like the Mini Cooper, to midsized station wagons, like the Kia Rondo.

The overall winner in the mpg race was–hold on to your hats–the Toyota Prius, with a rating of 48 mpg city and 45 mpg highway. Here’s the top ten, in case you’re in the market for a brand-new car. The kicker is that these cars, with their low fuel usage and emissions, are the hottest cars on the lot these days. Finding one at a reasonable price may be tricky.

To see the full list, visit FuelEconomy.gov.

1. Toyota Prius, 48/45
2. Honda Civic Hybrid, 40/45
3. Smart ForTwo convertible and coupe, 33/41
4. Volkswagen Jetta and Jetta Sportwagen diesels, 30/41
5. Toyota Yaris, 29/35
6. Mini Cooper manual, 28/37
7. Nissan Versa, 26/31
8. Mini Cooper automatic, 25/34
9. Hyundai Sonata, 22/32
10. Honda Accord, 22/31

And for you glass-half-empty, hell-in-a-handbasket types, the EPA lists the cars with the worst mpg as well. That list tends more toward the Lamborghini/Ferrari/Bentley end of the spectrum, though I was suprised to see the Saab 9-3 on the worst list.

This month Interstate 65, which runs from Gary, Indiana, to Mobile, Alabama, become America’s first biofuels corridor, with help from the U.S. Energy Department, General Motors, and the Ethanol Promotion and Information Council. What does a biofuels corridor mean for drivers? It means that there are dozens of stations along I-65 offering E85 (85% ethanol, 15% gasoline) or B20 (20% biodiesel, 80% regular diesel), each spaced no more than a quarter tank apart.

The idea is less romantic than Route 66, but far more practical and forward-thinking. The route covers four states: Indiana, Kentucky, Tennessee, and Alabama. Seems like the perfect place to try out your new $2.4-million Koenigsegg CCXR supercar, which runs on E85. It could do this route from stem to stern in a cool three and a half hours.

If you love the safe feeling of driving a Volvo but not the around-town gas mileage (16 mpg in an S80!), do the Swedes have good news for you. Volvo announced at the Paris auto show, where green was king, that it would introduce start-stop technology in some of its 2009 models, with diesel hybrids to appear in 2012 and plug-in hybrids to come sometime soon after that.

The smaller C30, S40, and V50 will get the start-stop treatment first. This relatively uncomplicated technology shuts off the engine when it’s not under load, at stop lights, say, and starts it back up when you’re ready to get moving. Start-stop will make its way into the rest of Volvo’s lineup in the future.

Diesel hybrid systems will be used in the company’s larger vehicles, like SUVs, wagons, and the big sedans. The Volvo setup will have a 5-cylinder turbodiesel engine to drive the front wheels and an electric motor to power the rear wheels. At low speeds, the electric motor will be able to do all the necessary work.

Automotive News mentioned that electric motors and diesel engines have the same shortcoming, namely a lack of horsepower at high rpm. Volvo execs say that they’re more interested in reducing CO2 emissions, and this is the best way for them to do that. I doubt many people were buying Volvo wagons for their sportiness, anyway.

The Northwest Automotive Press Association has released the results, and the first-ever Best Green SUV Award went to the 2009 Ford Escape Hybrid. The field included two hybrids, a diesel, and an SUV with variable cylinder management technology.

SUVs in the green category were judged alongside “regular” SUVs and were scored on the same on-road and off-road handling capabilities, comfort, ergonomics, etc. In addition, the Green SUVs were evaluated on their fuel economy and emissions technologies and innovations.

It’s interesting to note that, because the Green SUVs were run over the exact same courses as the conventional SUVs, they won in other categories as well.

Best Family SUV

• $30,000 - $50,000 price range as tested
• Kid-friendly features
• Winner: 2009 Dodge Durango HEMI Hybrid

Best Luxury SUV

• Above $50,000 as tested
• Advanced luxury features
• Winner: Mercedes-Benz ML320 BlueTec Diesel

Hyundai’s got the blues. Two of them, to be exact. Like Mercedes-Benz, the Korean manufacturer has apparently tired of everything being green and branded its eco-conscious automotive efforts blue, as in the i20 blue and Santa Fe blue Hybrid, both of which debuted at the Paris auto show in early October.

The “blue” designation doesn’t mean hybrid; it means aerodynamic, efficiency, and weight measures have been taken to lower the car’s environmental impact. In the case of the i20, Hyundai took the following steps to lighten its footprint:

• 1.4-liter diesel engine
• six-speed gearbox, rather than a five-speed
• low-friction engine oil
• software to optimize timing, injection, and idle speed
• ISG start-stop system that cuts the engine while the car is not moving and not in gear
• full-length covers underneath the car to reduce drag
• Michelin Energy low rolling resistance tires

All this adds up to 15% lower carbon dioxide emissions and a 15% improvement in fuel efficiency (from 55 mpg to 63 mpg).

The Santa Fe blue, meanwhile, has a 2.4-liter engine mated to a 6-speed transmission and a 30 kW electric motor and a lithium polymer battery. The company says that this parallel hybrid architecture, as they call it, will be the basis for all Hyundai’s hybrids in the future. In the Santa Fe, the system returns 38 mpg. As part of the new blue lineup, it also incorporates many of the features, such as ISG start-stop, found in the i20 blue.

October 4 is opening day at Mondial de l’Automobile, or the Paris Auto Show to most Americans. Europe has long had more small cars that get better gas mileage than what we can buy in the U.S., and a wider array of clean diesel cars. We can certainly expect to see more of these kinds of autos in Paris this year; the difference is that now we want them, too.

Here’s a list of debuts and concepts to look for at Mondial de l’Automobile as the reports start filling the blogosphere next month.

Debuts

• Ford Fiesta ECOnetic, 65 mpg and not U.S.-bound
• Hyundai Santa Fe Hybrid, with lithium-ion batteries
• Nissan Pixo minicar, one foot shorter than the Chevy Aveo

Concepts

• Citroen Hypnos hybrid
• Honda Insight hybrid, poised to battle the Prius
• Lexus LF-Xh hybrid, based on the concept LF-X SUV
• Nissan Nuvu EV minicar
• Opel Insignia EcoFLEX sports tourer, clean diesel on sale in Europe next spring
• Peugeot hybrid
• Renault Ondelious diesel mild hybrid
• Suzuki SX4-FCV fuel cell vehicle, already certified in Japan

Australians John and Helen Taylor are on their way to a new record in fuel efficiency. The couple, who’ve been setting fuel economy records for a quarter-century, are touring the U.S. in a clean-diesel VW Jetta TDI. As of September 10, the Taylors had covered over 2,700 miles and averaged 58.78 mpg. The current record for lowest fuel consumption on a nationwide drive is 51.58 mpg, so the Taylors are in good shape so far.

They began their latest record-breaking attempt to drive across the lower 48 in Chantilly, Virginia, and will end it September 26 in Beckley, West Virginia, after looping through Vermont, Montana, California, Louisiana, and points in between. The Taylors are using fuel-saving tacticts of the sort they teach in their fuel economy workshops, like avoiding idling and high speeds, plus all the GoodGreenCars.com faves like checking tire pressure and planning your route.

Check out Fuel Academy, the Taylors’ web site, for posts from the road and more information about their efforts to reduce oil consumption and CO2 emissions. They hold 46 speed driving world records and 36 fuel economy world records, so it sounds like they know how to have fun while reducing their impact on the planet.

We Americans have it pretty good — freedom of speech, religion, and the press; pursuit of happiness; pulled-pork sandwiches — but not when it comes to green cars. Here’s a rundown of the latest models we want, but can’t have:

• Diesel-powered Ford Ka This little number will get 56 mpg from it’s 1.3-liter engine, and put out 75 horsepower. At the Ford presentation I recently attended, someone asked speaker and powertrain expert Dan Kapp about Euro-spec clean-diesel Fords coming to the U.S., and he said not in the foreseeable future.

• Ford Fiesta ECOnetic Another small, diesel-powered Ford. This one, which goes on sale in the U.K. in November, gets 65 mpg and would be priced similarly to the Toyota Prius, if it ever made it to these shores. Which it won’t. Ever, according to Business Week.

• Honda Fit Hybrid So Ford says it won’t bring its diesels to the U.S. because we’re all about hybrids, so why has Honda decided not to go forward with its Fit Hybrid? Competition with itself. It wants all the hybrid love to go to its new Insight, due next spring. So no one gets the Fit Hybrid until the next redesign, a Honda spokesman told Edmunds.com.

• VW BlueMotion Diesel Golf The latest TDI-powered Volkswagen to come down the pike is a quick little four-door hatchback that gets 52 mpg, according to a VW press release, while still achieving 103 hp and a top speed of 117 mph. Luckily, VW did deem the U.S. worthy of the new Jetta SportWagon TDI, which gets 40 mpg on the highway and emits a mere 6.4 tons of CO2 annually.

The Alternative Energy and Transportation Expo will roll into Santa Monica for the third straight year September 26-27, at the Santa Monica Civic Auditorium. For the first time ever, the show will also set up camp in Texas, at the Austin Energy Alt Car Expo inside the Palmer Events Center October 17-18. Both events are free, free, free.

If you’re new to alternative-energy-powered vehicles, these events would be a good place to start. More than 150 exhibits will detail different fuels, such as hydrogen, hybrids, ethanol, electricity — both AC and DC — and even natural gas and propane. Experts will be on hand to answer any questions you may have, whether you’re an SUV driver thinking about driving greener or an engineer who converted his Porsche 914 to an AC motor.

Perhaps the most useful part of the expo is the Ride and Drive lot, where visitors can experience alternative fuels first-hand and evaluate their pluses and minuses from the driver’s (or passenger’s) seat. Seminars and panel discussions will be held during both weekends, featuring authors who’ve analyzed the future of the auto industry and movers and shakers from within the industry itself.

At a press event in Portland, Oregon, Dan Kapp, Ford’s director of powertrain research, said that the company has plans to become the number-one hybrid  producer in the country next year. By adding hybrid versions of the Ford Fusion and Mercury Milan to the Ford Escape and Mercury Mariner hybrids already on the market, Ford will double the number of its hybrids on the road.

Kapp laid out Ford’s long-term strategy, from today to 2050. The company plans to migrate its advanced fuel-saving technologies, like hybrid systems and the new EcoBoost engine, across the product line by 2012, so at least a few Ford, Lincoln, and Mercury vehicles will get a little better gas mileage. By 2020, Kapp said Ford will fully implement current technology and begin to delve into more gasoline-electric hybrids, plug-in hybrids, and more. After that, the plan is to roll out hydrogen fuel-cell cars, biofuel-powered vehicles, and whatever other new technologies have developed by then.

Kapp was eager to point out the advantages of Ford’s new EcoBoost engine, which uses gasoline direct injection and turbocharging to raise fuel efficiency by as much as 20% and lower tailpipe emissions by as much as 15%. The physically smaller engine will be able to deliver the same or greater power as traditional Ford engines, and will be available first in the 2009 Lincoln MKS sedan.

Kapp pointed out that while Ford was not pursuing hydrogen-powered cars as quickly as Honda, nor was it chasing Chevy’s PHEV Volt with any conviction, it does have the first driveable hydrogen fuel-cell PHEV in the Edge HySeries. The fleet of 30 cars is still very much in the test stage, and Kapp noted that hydrogen fuel has “monumental infrastructure problems.”

When fielding questions about bringing clean diesel cars from Europe (answer: not any time soon), a fellow journalist mentioned that he ran his diesel-powered Ford truck on B99 every summer. Kapp nearly choked on his coffee when he heard that one of his trucks was being powered by 99% biodiesel a few months out of the year. I was surprised that he was surprised — he was in eco-conscious Portland, after all.

Inspired by Willie Nelson’s commitment to biodiesel and the cross-country races of the ’60s and ’70s, Nik Bristow and a partner will bomb non-stop from New York to L.A. in a biodiesel-powered Jetta starting September 22. The trick? They’re going to do the Willie Run, as they call it, on one tank of Bio Willie fuel.

While biodiesel does get good mpgs, it doesn’t get 3,000 miles per tank. That’s why, according to Autobloggreen.com’s interview with Bristow, the Jetta has been outfitted with a huge spare fuel tank, just like the Cannonball Run guys used to do.

The Willie One, as the Jetta has been dubbed, has plenty of room for sponsors’ names. So if you’ve always wanted to see a car with your name on it but don’t have the $300,000 to slap a sticker on Dale Jr.’s car, this is your chance. Sponsorship of the Willie One starts at five bucks.

The NY Times reported last weekend on a dozen autos you might not expect to get such great gas mileage. Among their picks was a Corvette, which I can tell you first-hand gets better gas mileage than you’d expect, at 26 mpg on the highway — if you drive it reasonably and responsibly. But who does that in a Corvette?

Here’s the Times’s list with combined miles per gallon, but you’ll want to read the whole list on the newspaper’s Web site. Reporter Lawrence Ulrich includes everything from tiny econoboxes to full-size SUVs and pickups. He purposefully left out the obvious, like the Prius and Honda Civic, to focus on overlooked models in broad categories.

• Toyota Camry Hybrid, 34 mpg
• Volkswagen Jetta TDI, 33 mpg
• Mini Cooper, 29 mpg
• Nissan Versa, 27 mpg
• Honda Accord coupe, 24 mpg
• Toyota RAV-4, 24 mpg
• Mazda 5, 23 mpg
• BMW 328i, 22 mpg
• Toyota Tacoma, 21 mpg
• Chevy Corvette, 19 mpg
• Ford Flex, 19 mpg
• Mercedes-Benz GL320 Bluetec, 19 mpg

New online app Fuelly allows users to record mileage, track it over time, share it over the network with other Fuelly users, and compare fuel economy to EPA numbers. Do it from your desktop or take on the go with your iPhone or other mobile, Web-lovin’ technological wonder.

There are currently, as of the minute I’m writing this post, 1,981 cars registered with the site. Interesting note: there are more Jettas using Fuelly (71) than Priuses (34), and more Civics (157) than any other model. There’s one Ferrari Testarossa listed, but right now it says it gets 200,000 mpg after one fill-up. I find that hard to believe.

The site also offers gas-saving tips, most of which I’ve covered over at sister site RiverWired.com, but they always bear repeating. And there’s a forum for asking questions and posting your own fuel-saving tips.

You, Citizen Driver, are not the only one who cringes every time you fill the gas tank or feels  a pang of guilt when your car belches those nasty emissions out the tailpipe. The American Le Mans Series of racing professionals knows your pain. That’s why it’s instituting the Green Challenge at its signature event, the Petit Le Mans at Road Atlanta, scheduled for October 4.

Three factors will be considered in naming a winner of this race-within-a-race:

• Performance (of course — this is a race)
• Fuel Efficiency
• Environmental Impact

Cars will be ranked by the amount of energy they use, the greenhouse gases they emit, and the amount of gasoline they displace over the course of the race. Which boils down to going as far as they can, as fast as they can, with the least environmental impact.

ALMS has been taking steps all season to lessen the environmental impact of racing. GM, Audi, and others have introduced race cars running on alternative fuels like E85 and clean diesel. You can bet those teams will be vying for the Green Challenge title. Race fans and consumers are winners in this event, too, as technological innovations on the track often trickle down to cars on the showroom floor.

Even NASCAR is dipping a toe in the clean-and-green waters. Michigan International Speedway, which hosts two NASCAR events during the season, stepped up its recycling efforts this year. During the Lifelock 400 weekend in June alone, MIS collected 15.3 tons of aluminum, plastic, and cardboard. They’re even recycling construction materials from some recent upgrades to the facilities, and they’ve instituted an office recycling program.

Eco-friendlier fuels, recycling … What is auto racing coming to? Oh, right. Its senses.

Tonight, stars I am too old to have heard of will be escorted to the red carpet at the Teen Choice 2008 awards in a fleet of Volkswagen’s brand-new 2009 Jetta TDIs, which run on clean diesel. Like everone else in Hollywood, the Teen Choice awards are going green, so Fox, which is airing the show, partnered with VW to showcase its new entrant into the eco-car market.

The ceremonies began their green initiative last year, and will continue to use recyclable materials in the sets and press credentials printed on recycled paper. The Jetta TDI, for its part, uses high-performance, low-sulfur diesel fuel and meets the strictest fuel emissions in the country — including California’s.

At least 15 stars will be arriving at the awards show in the Vee-Dubs, including James Marsden (Cyclops in the X-Men films), American Idol runner-up Katherine McPhee, and Jerry O’Connell, who was in Stand by Me and is now married to Rebecca Romijn. I would have to Google the rest of the list to find their pop-culture accomplishments, but they include Chase Crawford, Leighton Meester, Ed Westwick, Drake Bell, Brittany Snow, JoJo, Rachel Bilson and Sophia Bush.

Automakers have dreamed up a new all-green event to coincide with the wildly popular Woodward Dream Cruise. They call it NextCruise, and it will debut in Pleasant Ridge, Michigan, with a public preview Friday, August 15 and activities Saturday, August 16.

Nine automakers have signed up — General Motors, Ford, Chrysler, Toyota, Nissan, BMW, Mercedes-Benz, Audi, and Volkswagen — plus Bridgestone and the the IndyCar and American Le Mans racing series. All the participants aim to prove that green technology is clean, comfy, and cruise-worthy with displays and free 15-minute test drives.

Hybrids and clean diesels will make up the bulk of the event, in contrast to the cars rolling along Woodward Avenue at the14th annual Woodward Dream Cruise. Classic and muscle cars both pristine and hot-rodded will cruise from Ferndale, Michigan, to Pontiac in one of the largest vintage car cruises in the country. If anybody needs to be convinced of the fun to be had in low-emissions vehicles, it’s these guys.

Now that Mini is going electric, everybody wants a piece of the action. Smart has a test EV running around in Europe right now, and while Tata has long had plans to introduce an electric car, they’re going ahead with a diesel this year.

The electric Smart ForTwo, known as the Smart ed, has a 41-hp electric motor and sodium-nickel-chloride batteries. It gets about 70 miles per charge, and has a maximum speed of 70 mph, which makes it a reasonable commuter EV, even if your commute involves highways. Price and market haven’t been announced, but they do expect it to go on sale in 2010. Cross your fingers that it comes your way — and you can afford it.

While we may have to wait a while for the EV version of the Tata Nano, the diesel version will hit the Indian market in October. The hatchback will go a rocking 50 mph from its little 33-hp, 2-cylinder diesel engine, but it gets 52 mpg city, 61 highway. The added efficiency will drive up the regular Nano’s price of $2,500 to about $4,200.
