Bad videos of uninteresting things on Youtube.

Compact pickups? No, old school mini trucks.

Holy crap I love old-school mini trucks. The very attributes that made mini pickups of the '70's and '80's so popular: simplicity, low cost, and economy; made them excellent canvases for customization too. Unfortunately, the mini truck scene has lost sight of the aesthetic. Modern custom mini trucks are a garish mess of graphics, huge rims, hydraulic pumps, and DVD screens. Classic mini trucks, although flashy, exhibit quite a bit of constraint in comparison. For example:

Cool: Monochrome magenta
Not Cool: Lime green with graphics

Cool: Static drops
Not Cool: Airbags, hydraulics

Cool: Cranked torsion bars
Not cool: Body drops

Cool: 15" wheels
Not cool: 20" wheels

Cool: Subwoofer walls
Not cool: LCD screens

Cool: Tweed
Not cool: Tweed

When I calculated 16.26 MPG for the last tank in our Xterra today, I thought again about finding a unique, frugal alternative f0r c0mmuting and Home Depot runs. And I d0 need a place to apply my NOS Freestylin' and Rockville BMX decals...

Whatever happened to compact trucks?

2006-11-01T19:16:00.000-06:00

Jalopnik posted pics of this sublimely un-pimped 1967 Toyota Stout from SEMA today. This vehicle is almost completely perfect; I'd probably add a set of chrome steel fake slot mags to the "low-profile" 70 series Drag Rite bias plies. (What width are those babies? E? F?)

What happened to compact pickups? Today's "compacts" have grown in size, weight, price, and thirst until they carry few advantages over full-size pickups. If Toyota would release a truck in the spirit of the original Stout today, they'd have a runaway sales hit. The same could be said of Nissan's 620 "Bulletside" and Mitsubishi's original Mighty Max.

Until then, I'll have to reminisce about my uncle's new 1979 Plymouth Arrow Truck with rainbow tape stripe, chrome Fenton wagon wheels, and Wide Trac radials.

The Durocco

Anson added an additional 16v drivetrain to the rear of his 16v Scirocco. Sure it's freaking awesome, but what exactly is "green" about it?

As a hobby car, it racks up far fewer miles than a commuter. A car that spends most of its time parked or in pieces really uses very little fuel at all. Also (and this is probably stretching), it represents reusing materials that otherwise would go to scrap. (Yeah, that's the ticket!)

Anson does also drive a WVO-converted Mercedes.

In any case, it's unbelievable. Check out the videos to see him walk a Porsche 911 and drive sideways for minutes at a time.

Chevy Tahoe EPA MPG numbers optimistic?

2006-10-23T15:05:00.000-05:00

I noted in a previous post that although the 2007 Tahoe's EPA mileage numbers aren't exactly stellar, they're far better than they were only a few years ago. The 2007 Tahoe 2wd 5.3 is EPA rated at 16 MPG city / 22 MPG highway.

But I may have spoken too soon about the apparent frugality of the new 'Hoe. Reports on the Web are reflecting real-world mileage figures that are significantly poorer than the advertised 16/22.

MPH Online's Blog notes

I just managed a paltry 16.3 mpg in a 2007 Tahoe on my 50-mile (each way) daily commute, 90 percent of which is highway driving. The problem? The 4-wheel drive Tahoe claims a fuel economy of 15 city, 22 highway. The last Tahoe I drove, which I took to Chicago, only gave back 14 miles per gallon. That truck had barely any miles on it and was a preproduction unit, so I was willing to give it the benefit of the doubt. But that's not the case here since the more recent 'Hoe was well above its break-in miles

A thread on Chevrolet Forum asks users of their MPG, assuming 50-75% highway driving:

Viperjuice posts: well i've been driving back and forth to work some city some highway and i average about 15.. i had it on the Masspike, which is alot of up and down highway and i reset it and was getting only 16.8.. honestly i'd go with the trailerblazer with the dod v8.. lighter truck, therefore better mileage.. and they defenitly are much better than those l6 engines.

-------------

Swatson1 posts: I'm getting 13.7 mpg overall average in my LTZ. I drive about the same percentage of hwy and city miles. I'm severely dissapointed in the gas mileage. It seems to make a difference whether you run the a/c or not. I'm in texas where it is hot, so I run it a lot.

-------------

ZX1100F1 posts: I have a 4X4 model with 4.10 gears, I get about 16.5 MPG avg with about 50/50 Hwy/City driving, I just turned 3K miles last week.
I took a trip the first week I owned it and avg'd a little over 18 Hwy, got 455 miles one tank before the light came on and I filled it up

You get the picture. So what's the problem? Active Fuel Management. My own theory is that the software algorithm behind this feature on the 5.3 Tahoe is optimized for the EPA test cycle but not necessarily for real-world driving conditions. Or perhaps the software has been revised between the test and the release of the vehicle. Or heck, maybe GM slipped the EPA a ringer.

In any case, I had considered the Tahoe despite its borderline-lousy MPG, for its utility and comfort. A herniated disc requires me to drive a vehicle with big seats, a high seating position, and plenty of legroom. But if the mileage is as bad as user reviews have indicated, the deal is off.

Design Belies Process: Homer's Dream Car

2006-10-17T16:40:00.000-05:00

In the Simpsons episode 7F16, Oh Brother Where Art Thou, Grampa Simpson reveals to the family a long-hidden secret: Homer has a half-brother. Homer's brother, Herb Powell, is the head of the Powell Motors car company, and decides that as an "average" American, Homer is the perfect designer for a car catering to other "average" Americans. Homer is given free design reign and all ends poorly. Homer's car is finned monstrosity featuring three horns that play "La Cucaracha" and a separate sound-proof bubble dome for the children (featuring optional restraints and muzzles.) Powell Motors is doomed.

I've often used this scenario as an example of not asking users the right questions. By asking "Do you wants" instead of "Tell me abouts," you're leveraging the user's design expertise and not your own.

Consider any design suggestion a user makes not as a design requirement, but as a reflection of a problem that needs to be solved. Does the user really want three horns that play La Cucaracha, or does he want to be noticed? And never, ever ask yes or no questions. If you ask a parent "How about a soundproof bubble for the children with optional restraints and muzzles," of course the parent is going to say yes.

Ultimately however, the episode's punchline isn't that Homer is a poor designer and that his efforts have yielded a monstrosity. Homer was tasked with designing a car to meet his own needs and desires, and he succeeded. The punchline is that his half-brother Herb mistakely assumed that as a consumer, Homer was representative of anyone other than Homer.

To avoid releasing a Homer, a team must:

Inform the design with information gathered from real, representative users. What are the users' goals? What are their characteristics? What challenges do they face with similar products?
Design the product to meet these considerations.
Validate the design decisions by watching real users interact with the product.

Success lies in designing a product that addresses the problems that many real users wish to solve.

Silverado ads get "strong reactions" from viewers, hippies

2006-10-16T10:36:00.000-05:00

"I'm meeting you halfway, you stupid hippies." (Futurama 2acv03, A Head in the Polls)

First, I'd like to preface this post by saying that I like full-size trucks, especially Chevy trucks. If they were more economical and ecologically sound to operate, I'd consider buying one. But apparently I'm a bad American, perhaps even a hippie.

So I tried to pause my DVR during an airing of a Chevrolet "Our Country. Our Truck" commercial last night in an attempt to catch a glimpse of the new Silverado, but I couldn't hit pause fast enough to catch that frame.

John Mellencamp sings "This is Our Country" (I kid you not) over a montage of pure Americana (R). Rosa Parks, the Twin Towers, Richard Nixon, Charles Whitman - flip, flip, flip. It's not that the spot exploits 9/11 or any other event or series of events in American history. It's that the spot exploits 9/11 and every other event and series of events in American history. It's hamfisted, manipulative crap that makes "We Didn't Start the Fire" appear sincere in comparison.

Autoweek quotes Bill Ludwig, the "Chief Creative Officer" of Campbell-Ewald, the advertising firm responsible for this piece of mungus:

Ludwig says he anticipated that the Silverado spot would generate complaints. The commercial is about America "and the knocks we have taken and pulling ourselves up by the bootstraps," he says. "Anytime you are provocative, you are going to elicit some provocative responses.

"If you want to make a statement that rings true with the majority of people, you are going to piss off some people. There are a lot of cynical people out there who don't react well to this, and a lot of people who will never get behind the wheel of a pickup.

"So let them get into their Volvo sedans and complain about this spot that they see as exploitive," he says. "This is not for them. The biggest risk you can take is to play it safe."

Exactly what GM needs right now! Someone to challenge potential buyers to not buy their products. So you hear that, dissenters and Volvo sedan drivers? GM's make-or-break product is not for you!

Tips on recycling old desktop computers

2006-10-15T20:44:00.000-05:00

As awareness of the presence of toxins like lead, zinc, and cadmium increases, so does interest in recycling old desktop computers and electronic products. This article

First, donate the equipment to charity if possible. My only caveat would be to remove and destroy a PC's hard drive before donating the machine. I realize that a PC without a hard drive is much less useful to a charity than one that actually works, but this is the best way to know that your personal information won't end up in the wrong hands through an auction or thrift store sale.

Second, consider recycling e-waste like old desktop computers. Call your city government to see if your local environmental waste ("sanitation") department has an electronic waste recycling program.

See the Basel Action Network's E-Stewards for a list of responsible e-cyclers that have agreed to the most rigorous criteria for sustainable electronics recycling.

Global warming research on Earth climate

2006-10-15T20:07:00.000-05:00

The Stanford Solar Center projects the following for the rest of the 21st century, based upon the body of global warming research on Earth climate change:

According to the Intergovernmental Panel on Climate Change (IPCC), average global temperatures may increase by 1.4-5.8ºC by the end of the 21st century. Although the numbers sound small, they can trigger significant changes in climate. (The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC.) Besides resulting in more hot days, many scientists believe an increase in temperatures may lead to changes in precipitation and weather patterns. Warmer ocean water may result in more intense and frequent tropical storms and hurricanes. Sea levels are also expected to increase by 0.09 - 0.88 m. in the next century, mainly from melting glaciers and expanding seawater . Global warming may also affect wildlife and species that cannot survive in warmer environments may become extinct. Finally, human health is also at stake, as global warming may result in the spreading of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor air quality.

The difference between global temperatures during an Ice Age and an ice-free period is only about 5 deg. C. (shudder)

Recent news on global climate change

2006-10-15T19:59:00.000-05:00

The number of parties that will contend that global warming is not real is shrinking fast. Gov. Arnold Schwarzenegger is embracing a carbon trading initiative in the state of California (source = SF Gate):

The executive order is the first step in creating a system that helps California's largest manufacturers comply with stricter environmental regulations, a Schwarzenegger administration official said. Industrial corporations and utility companies must cut their greenhouse gas emissions by roughly 25 percent by 2020.

"Gov. Schwarzenegger wants to build a large, robust carbon trading market that will dramatically reduce emissions," said Schwarzenegger communications director Adam Mendelsohn. "The more robust the market, the more effective we will be."

The executive order "will now get the northeast states working with California to trade credits in the very near future," Mendelsohn said.

In defense of the Chevy Tahoe

2006-10-15T17:20:00.000-05:00

Large sport utility vehicles are inefficient for the tasks they often support: commuting and carrying 1-2 passengers.
That being said, they're better than they were only a few years ago.

Compare the original 1995 Chevy Tahoe and the new 2006 Chevy Tahoe (source = Edmunds.com):

1995 Chevrolet Tahoe
Curb Weight: 4980 lbs
EPA Mileage Estimates (City/Highway): 12 mpg / 15 mpg
Base Engine Size: 5.7 liters
Horsepower: 200 hp
Torque: 310 ft-lbs

2007 Chevrolet Tahoe
Curb Weight: 5265 lbs
EPA Mileage Estimates (City/Highway): 16 mpg / 22 mpg
Base Engine Size: 4.8 liters
Horsepower: 295 hp
Torque: 305 ft-lbs

This represents an increase of rated city/highway fuel economy of 33 and 47 percent, respectively. You would be hard-pressed to find a increase in fuel economy anywhere but the light truck segment. The vehicle's gained 300 pounds in curb weight in the last 12 years, but so has the Honda Civic.

Don't get me wrong: it's still an inefficient vehicle, and it's shameful that a 5000 pound automobile doesn't have a true third-row seat. It is gradually improving though, and once it receives a 6-speed automatic it may hit a rated 25 mpg on the highway.
