Consumer Reports’ real-world mpg figures make the Prius even more appealing

Consumer Reports recently claimed that EPA's vehicle ratings routinely overstate how fuel-efficient cars and trucks are in real-world driving. For standard cars and trucks, the magazine says, EPA's ratings overstate real-world fuel economy by 30 percent. But for small hybrids, such as the Toyota Prius, they claim that EPA overstates actual miles-per-gallon by a hefty 42 percent. (Ouch.)

Now, I believe that there's reason to question Consumer Reports' figures. Of course, I have read a number of reports that the Toyota Prius doesn't actually get the EPA-rated 55 mpg in combined city/highway driving (though some people -- particularly those who've optimized their hybrid-driving habits -- get pretty close, and these folks actually squeezed out 110 mpg from their Prius, albeit in highly non-standard driving conditions). But I'd never heard any claim that the typical Prius averages just 32 mpg -- which is what the magazine's figures suggest. See this comment by WorldChanging's Jamais Cascio for a similar take.

But, just for the sake of argument, let's take the CR figures at face value, and assume that small hybrids' mileage really is overstated by 42 percent, vs. just 30 percent for regular cars. Doesn't the higher mpg reduction for hybrids suggest that their fuel-savings advantages vs. regular cars are overstated -- and that they don't save as much money as advertised?

Actually, no. As counterintuitive as it may sound, the Consumer Reports figures, on their face, actually bolster the economic case for buying hybrids.

It’s an electric bike

I don't know what this guy's hang-up is with Deuce Bigalow, but high gas prices and the following comment by Odograph on the cost of plug-in electric hybrids got me thinking again. In lieu of paying $3-6K more for a plug-in hybrid electric car:

What if you drive a prius and plant $3-10K worth of trees? What if you skip the prius, buy an echo and plant $13-20K worth of trees? What if you spend $1k and ride a really nice bike?

I especially liked his last idea. I jumped on the net to see what was new for electric bikes and bought a conversion kit from a shop somewhere in California for $300. UPS dropped it off at my house last Monday and I had it on my bike an hour or so later.

Umbra on true hybrids

Dear Umbra, I read the New York Times article that reported auto manufacturers are using hybrid technology to boost power rather than improve mileage. It specifically mentioned the Honda Accord, claiming that the mileage difference between the six-cylinder and the hybrid is minimal. What are the facts here? Is there a hybrid that really, actually, […]

Beware the hype around plug-in hybrids

An article in Business Week Online tells us that experimental hybrid cars get up to 250 mpg (a very similar article appeared in the New York Times business section a couple of months earlier). I enjoy reading between the lines of lay press science and technology articles. There was a great discussion in Grist on this subject not too long ago.

Gremban ...spent... $3,000 tinkering with his car... [I]n the trunk sits an 80-miles-per-gallon secret -- a stack of 18 brick-sized batteries... [T]he extra batteries let Gremban drive for 20 miles with a 50-50 mix of gas and electricity.

In other words, for his $3000 he will get 80 miles per gallon for 20 miles before his carriage turns back into a pumpkin. For the rest of the day he will carry a hundred pounds of bricks around in his now-useless trunk, which by the way will degrade his gas mileage. For the first 20 miles he drives each day he will save 0.25 gallons, thus recouping his $3000 in about twenty years, assuming his batteries last that long. The more miles he drives after the batteries go dead, the worse things get because of the extra weight of the dead batteries in his trunk. Which leads me to ask: If his commute is only ten miles each way, why not just ride a bike, get a little exercise, and save $3000? You can also get 80 mpg out of a 40-mpg car by carpooling with one passenger, or get 120 mpg with two passengers, or 160-mpg with three passengers.

Meet the world’s first hybrid-cab driver

Like any self-respecting cabbie, Andrew Grant has a talent for small talk. But when the conversation turns to his prized 2004 Toyota Prius, things get a bit more animated. Andrew Grant. “Gave Cameron Diaz a lift once,” he says matter-of-factly, leading me toward the Vancouver curb where the curvaceous car is parked. “Oh, yeah? What […]

They’re everywhere!

I can't go outside anymore in Seattle without seeing a Toyota Prius -- actually make that several. To escape the onslaught, I ducked into a movie theater this past weekend to watch War of the Worlds. Just as I was thinking it would be just me, Tom, Dakota and a few alien friends, Mr. Prius showed up on the big screen to remind me that he's watching me. Is there no escape!?

Harder than it looks?

We're constantly hearing about how insanely popular the Toyota Prius is -- the celebrities, the cachet, the waiting lists.

Is it possible that said popularity is just a blue state phenomenon?

I ask because we recently got an email from a reader, Linda, who's having trouble selling hers. No, really!

My husband received an international assignment so we are moving to Belgium. We have decided to sell my beloved 2004 Prius. I live in Pocatello, Idaho, and in this land of conservatives, where they are sure that global warming is a figment of Al Gore's imagination, there appears to be no market. I've had an ad in various papers for over a month and no calls. It is salsa red and comes fully loaded (package #7) with everything except GPS. The blue book value on this gem is $23,360, I bought it for $24,800. I'd be willing to negotiate around $23,000. It has 13,600 miles and is in excellent condition with seat covers and even a 1.25 inch hitch for a bike rack in back. (I could throw in the bike rack too, if someone wants it!)

So, Gristmill readers, I'm curious: Do you have any tips or advice for Linda? Or ... do you want her Prius? Tell us all about it in comments!

FYI: Linda's phone number is (208) 232-8207.

Friedman drives home the geo-green point.

Last Thursday, Tom Friedman again returned to his geo-green pulpit. Citing the Set America Free coalition, Friedman asserts that the solutions to our foreign oil addiction (and 500 miles to the gallon of gasoline) are "already here."

Sounding remarkably similar to a Max Boot column in the LA Times (mentioned here on Gristmill in March), Friedman advocates the two-pronged approach of electric plug-in vehicles and flex-fuel vehicles. These powers combined result in 500 mpg.

My reaction: Flex-fuel? Great. Shifting our massive fleet of cars and trucks to run off of electricity? Maybe not so great. After all, don't we get over 50% of our electricity from carbon-intense coal?

My resulting back of the envelope calculations are below the fold.

Are there problems with the Prius?

Tucked into the business sections of newspapers today is this story: The feds are investigating claims that Toyoto Prius engines may unexpectedly stall out at highway speeds.

The development may be but a hiccup interruption for Toyota, as the automaker continues to press its green advantage on American consumers while American automakers stand pat (or worse) on fuel efficiency. After all, the National Highway Traffic Safety Administration has received only 33 complaints about stalled engines -- a small number given the something like 75,000 Priuses on the road for the model years 2004 and 2005.

On the other hand, if there is any credence to the claims, one can envision the concerns spiralling into a whirl of negative publicity for Toyota -- something that opponents of California's clean-car standards (e.g., GM) would certainly take quick advantage of. Here's hoping that there's no opening for a "Hybrid Veterans for Truth" campaign to get off the ground.
