2008 Mini Cooper

In my capacity as an automotive journalist, I have driven the Mini Cooper before. Several times, as a matter of fact. But when the red 2008 Mini with black stripes was delivered on Friday, I had a mission in mind. I was going to put its EPA fuel economy estimates to the test.

The Mini Cooper in my possession for a few days had a standard 1.6-liter, 16-valve, 4-cylinder engine that could turn out 118 hp. It may not sound like much, but in a car this small, it’s enough. It also had a six-speed manual transmission, which would help in the mpg department. The test car did have sport suspension and 16-inch wheels, rather than the regular 15-inchers, but I didn’t think that would affect the fuel economy much. The EPA estimated 28 mpg in the city and 37 mpg on the highway.

The morning the Mini Cooper appeared in my driveway, I was already late for lunch. I grabbed the keys, reset the mpg counter, threw the car in reverse, and tore off in the direction of the restaurant where I would meet a few friends. I did not drive responsibly. Safety was, as always, my priority, but speed came in a close second. I was surprised, on reaching the restaurant a few miles away, that I had still averaged over 32 mpg, even driving like a jerk.

Over the next few days, I drove in a much more sane way around Portland. Lots of in-town driving, some freeway, some stop-and-go traffic at 5:30. It never dipped below 30 mpg. As you can see, after five days of normal driving, I averaged 33.7 mpg. This is above the EPA’s combined rating for the Mini Cooper of 32 mpg.

Mini Cooper Fuel Economy

I have to give the car back, and it’ll be a while before I get another. BMW, which owns the Mini brand, is pulling back on its press loaners for now. In the meantime, we can all look forward to those precious few electric Mini E models coming to the States for real-world testing.

This car was provided for review by the manufacturer at no cost to the reviewer.

Yet another addition has been made to the online arsenal of tools for the savvy driver: CostToDrive.com. This easy-to-use web app asks for your start point, end point, and year, make, and model of the car you’ll be driving. It can then spit out the amount you’ll pay to fuel your rig for that trip.

I decided to give the calculator a test run, as I just took a drive to Auburn, Washington, for work, and I know what I spent on gas for that little adventure. The first thing I found was that if your car is older than 1999, you won’t find it in the drop-down menu.

Cost to Drive couldn’t find my little red truck in the system, so I entered it free-form style, including the MPG and size of the tank.  It told me I could expect to spend $25.75 on that trip, which was just about right. But I could have figured that out in my head using the information it had me type in.

The builders of the site call the process “galculating,” which is what I did while stuck in traffic on Interstate 5 yesterday. “If I sit here for x number of minutes burning y gallons of gas, how much time and money am I losing?” There’s nothing like a traffic jam to make word problems seem fun.

Cost to Drive may help you decide if a trip is worth it, or it may help you compare the cost of gas to the cost of a train ticket, but the math is pretty easy. I firmly believe you could figure this stuff out without a dedicated web site, but if your brain is having a difficult day, then Cost to Drive may help.

Greetings from the land of scooter commuters! After two months of sitting under the carport, alone but for the spiders weaving their webs all over her, my scooter, a 2002 Kymco People 50, is finally operational again, thanks to my first-ever at-home repair!

The summer saga began when I took the Kymco out for the first time, in May. I drove it a few miles and parked it while I volunteered at my local humane society. While I was volunteering, the entire contents of the gas tank leaked out onto the pavement. The maintenance guy stood watch to make sure it didn’t burst into flames, then used his forklift to put it in the back of a pickup truck to drive me home.

(Eco-recap: gas on the ground and running into a nearby rainwater grate is absolutely not good for the earth. Neither is strapping a scooter to the bed of a half-ton pickup truck.)

The guy at the shop where I bought my scooter in 2002, which by now has 4,500 miles on the odometer, said that Kymcos of a certain age can have leaky fuel filters. I asked if I could repair it myself, and he said, “You can do anything yourself, just be sure not to strip the rubber gasket when you tighten the filter.”

Cool, I thought, I can do this myself. Except that I’d never repaired anything mechanical before, and I was intimidated by the very idea.

Until last Sunday. I downloaded the repair manual for ten bucks, got out the socket wrenches, and took pictures as I went — kind of like digital breadcrumbs, in case I got lost. I found out that the hose was cracked, not the fuel filter, and bought a replacement part at the scooter shop for another ten bucks. All in all, from start to finish, it took a grand total of about two hours, three tools (socket wrench, allen wrench, and pliers), and $20.

So, if gas prices have you considering a scooter, go for it! They get great mileage (mine gets about 80 mpg) and are simple to repair — by you or your local shop.

The 2008 Dow Jones Sustainability Indexes have been released, and the Automobiles crown goes to Miss Germany: BMW. The report is labyrinthine and multi-partite, so I’ll try to break down the auto section to give GoodGreenCars readers an idea of what makes BMW so sustainable.

The review is produced annually by Dow Jones Indexes and SAM, a sustainability investment specialist. They analyze corporate economic (i.e., risk management), environmental (climate change mitigation), and social performance (labor practices) in 57 industries. BMW scored well enough in all three categories to be the leader in the Automobiles sector.

SAM and the DSJI aren’t in it for the love — they’re in it for the money. And the money says that investors are demanding sustainable practices from industries.

But this is not an endorsement of BMW vehicles as particularly green. The popular 3-series gets about 21 mpg combined and emits a middle-of-the-road 8-9 tons of CO2 annually, while the company’s MINI lineup is rated at 29 mpg and 6.3 tons of CO2 annually. At the other end of the spectrum, the top-of-the-line M6 gets 13 mpg and releases 14.1 tons of CO2 annually (it also starts at $101,000).

BMW has complained loudly about how difficult it will be for it to meet the new CAFE standards in the U.S., and has paid millions in fines for CAFE violations in the past few years. So while their manufacturing processes may be sustainable enough for the Dow Jones, they’re a little lacking where the rubber meets the road.

California Governor Arnold Schwarzenegger has teamed up with Governor Bill Ritter of Colorado to unveil the ecoDriving campaign. [WARNING: When you click on that link, the Governator immediately starts talking to you, with nary a stop or mute button in sight.] Auto manufacturers and dealers, along with industry leaders and politicians, have aimed the campaign at drivers who want to increase the fuel efficiency and reduce the emissions of the car they already drive.

The site offers tips like keeping tires properly inflated and “riding the green wave” — maintaining a steady speed to hit all the green lights on a long street. I have an uncle who is the king of this maneuver; I thought he was anal, but it turns out he’s a natural-born ecoDriver. The site also recommends keeping the gas cap tight to reduce evaporation.

There’s a clever ecoCalculator to tell you, based on your yearly mileage, mpg, and driving habits, how many pounds of CO2 you could be saving by adopting a couple new habits. If I kept the tires on my little red truck inflated, for instance, I’d save $68 a year on gas and keep 76 more pounds of carbon dioxide out of the atmosphere.

The site has games, resources, and will help you send a message to your governor asking him or her to sign on to the ecoDriving campaign. In a related measure, the National Automobile Dealers Association is recommending that its members give free green checkups in the month of September, along with child safety seat inspections.

2009 Chevy Silverado XFE

The Cobalt XFE has done so well for GM in these days of expensive gas and carbon-consciousness that it’s expanding the fuel-efficient XFE measures to the much larger Silverado, Tahoe, Sierra, and Yukon this fall.

The XFE models get 5% better mileage on the highway and 7% better in the city, which in trucks and SUVs as big as these is still a pretty small difference. All four models will get 15 city, 21 highway, as opposed to the vanilla varieties, which get 14 city, 20 highway. Huzzah!

The difference the XFE tweaks make is more noticeable in a small car like the Cobalt, where the company first used them. The regular-issue 2008 Cobalt with an automatic transmission gets 22 mpg city and 31 mpg highway; the 2008 FXE trimmed Cobalt gets 25 in the city and 36 on the highway.

The XFE designation means the vehicles were lightly redesigned with more fuel-efficient engines and better aerodynamics. The four new trucks all have:

  • 5.3L Flex-Fuel engine
  • Aluminum cylinder block and heads to reduce mass
  • Lowered suspension to improve aerodynamics
  • Aluminum wheels and spare to reduce mass
  • Low rolling resistance tires with higher tire pressure

Now 10% Cleaner!I don’t mean GM has found a way to turn corporate bluster into a fuel source, though that would ease the burden of the price of gasoline. A while back, the Department of Energy issued a challenge to automakers. It asked them to improve fuel economy by 10% using nothing but wasted exhaust heat to help power the vehicle.

GM, with BMW close on its heels, has developed a thermoelectric generator that could create enough electricity to augment or replace the usual alternator in a gasoline-powered car. Thermoelectric devices can use temperature differences to create electricity. When one side of the generator is heated, electrons move to the cooler side. The movement creates a current, which is collected by electrodes and converted to electricity.

The GM prototype is set to be tested in a Chevy Suburban next year, where a 10% fuel economy boost would mean a 1-mpg improvement. In a small car like the Chevy Aveo (the Suburban’s exact opposite), the boost could be enough to put its combined economy over 30 mpg. BMW and its research partner Ohio State University will run tests of its prototype next year, too.

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.

In Sioux Falls, South Dakota — just up the road from this week’s Sturgis Motorcycle Rally — one Harley-Davidson dealership has taken a bold step in the future of bikes. J&L Harley-Davidson has added Vectrix electric motorscooters to the mix on its showroom floor.

A recent story in the Argus Leader said Harley riders were open to the idea of an electric bike. The browsers quoted in the story didn’t say they were ready to give up their hardtails and ape-hangers for a 60-mph electric scooter, but they did like that the Vectrix was a zero-emissions vehicle.

Keep in mind, though, that Harleys are no slouch in the mileage department themselves. The 2009 Sportster 883 Low, to pick a model at random, gets 54 mpg in the city and 60 when you get your motor runnin’ and head out on the highway. But what comes out the other end, while hard to pin down with exact numbers, is apparently bad enough to warrant a California emissions fee of a couple hundred bucks.

PHEV PriusPlug-In Supply in Petaluma, California, is selling plug-in conversion kits for the Toyota Prius for the low, low price of $4,995. How can they sell it so cheap? First, that’s the price of the kit only, no shipping or installation included; second, they’re using CalCars Open Source Prius+ Technology as the basis of the conversion.

For you do-it-yourselfers and engineers out there, the kit includes lead-acid batteries and the box to hold them, charger, and wire harness. There’s also a switch you can flip to operate your Prius on battery power up to 52 mph — 10 mph higher than an unmodfied Prius. The converted PHEV can then run 10-15 miles on electricity before the gasoline engine kicks in, giving you 100+ mpg. Plug-In Supply even designed the kit to be upgraded to lithium-iron-phosphate batteries for longer range, when they become available.

There are currently only a handful of dealers where you can buy the kit and lug it home, but Plug-In Supply is looking for more. Those nine dealers already on board stretch from California to Florida and New Jersey, though, so you might be able to find one not too far from home.

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.

Photo by Niall KennedyNine 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.

Image from GreenCarSite.co.ukNow 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.

MyGallons.com promises that users can buy gas at today’s price and fill up in the future. Once the service is completely up and running (right now, you can reserve an account but not yet use it), users create an account, receive a MyGallons card, and check the web site for the current price of gas. You’ll be able to click a button to prepay for as many gallons of gas as you like.

The prices quoted on MyGallons are all regular unleaded. If you fill up with premium or diesel, the company will adjust your balance to account for that. If you’re out of town and the price of a gallon of gas is significantly lower — or higher — than your hometown price, MyGallons will adjust for that, too.

A program like MyGallons is designed to hopefully save you money — not gas. Having a prepaid fuel-only card will not improve your fuel economy. You may in fact get worse mileage out of your car if you drive like you know you paid less for that tank of gas.

Something to keep in mind: Tara Baukus Mello, lead analyst for the NADA Guides, told me in an interview that they don’t expect gas prices to rise any more this year, and they may even drop a little. Not a lot, but a little. With the price of gas in such flux, I’d check my crystal ball twice before prepaying for gas.

Ford Fiesta ECOnetic

After a disastrous second quarter, Ford announced that they’re going to build fewer trucks and SUVs and import six small cars that the company’s been selling in Europe. Consumers, and the dealers who can’t move SUVs off their lots, are chomping at the bit to get these more fuel-efficient vehicles.

The Ford Focus and Fiesta sedans and hatchbacks currently on the streets of Paris and London will be available in the U.S. in 2009-2010. At the same time, three truck plants — two in the U.S. and one in Mexico — will switch over to building the small cars that are currently in such short supply. I can’t help but think that a little bit of foresight on Ford’s part could have saved them from their worst quarter ever, which just ended with a total loss of $8.7 billion.

If we’re lucky, we Americans will get the latest Fiesta, the ECOnetic, which debuted in London July 22. It gets the best fuel economy in the company at 3.7 l/100 km, which on this side of the pond is an amazing 63.5 mpg. It also has the lowest CO2 output in its class, at 98g/km, yet it still has a top speed of 110 mph.

Tesla Roadster

The government released its latest fuel economy numbers, and one company was clearly at the head of the class. Telsa Motors, builders of the all-electric Roadster, rated a corporation-wide fuel economy of 244 mpg. The federal Corporate Average Fuel Economy (CAFE) standard is currently 27.5, so Tesla left that figure in the dust.

2008 models across the board, though, only rated 26.8. In 2007, the overall rating was 26.6, so that’s not a big improvement.

Analysts say the feds need to figure out a more fair way of comparing alternative-fuel vehicles to their conventional, gasoline-powered counterparts. The numbers are pretty revealing as they are, though. Handicapping EVs and other vehicles running on more efficient fuels to make the combustion engine look better seems misleading.

Tesla isn’t worried, obviously. They plan on selling their surplus CAFE credits as soon as they’re allowed to trade them with lower-scoring auto manufactuers.

In other Tesla news, the production line is cranking out Roadsters, after a fashion. There are 27 being assembled as of July 12, with a goal of 100 a month being produced by December of this year. The company has also opened its second store, this one in the San Francisco Bay area, with another four to come in the near future.
