This is an excerpt of a guest column Nick Chambers, editor of Gas 2.0, wrote for Popular Mechanics. You can read the whole column on the Popular Mechanics website.

The road trip—driving cross-country for days on end, crammed into a vehicle with your family—is virtually a required rite of passage for most Americans. The lure of the open road is as ingrained in our psyche and culture as the hamburger, football or fishing. So it’s no surprise that proposals for new types of taxes on these seemingly free highways—traditionally paid for by gas taxes and tolls—are causing an uproar.

Back in July of this year, Rep. Earl Blumenauer (D-Oregon) proposed a bill that allocates funds to research the effectiveness of taxing highway usage by the mile. On the surface, the bill seems to be laying the groundwork for big government to track our driving habits while simultaneously discouraging the driving of more fuel-efficient vehicles. It doesn’t have to be this way.

While domestic manufacturers have in recent years returned to the “retro” look, reigniting the nation’s passion for the muscle cars of yesteryear, the rest of the world has been giddy on egg-shaped hybrids and fuel efficiency vs horsepower.

There is an understandably large gap between the fuel-conscious and horsepower heavy crowds, but Popular Mechanics has undertaken a project to bridge that with their Eco+Muscle hybrid Dodge Challenger.

This post comes to you from Popular Mechanics. Written By Seth Porges.

Across the country, a handful of car makers continue their quest to bring a market-ready mega-mileage machine to market. The prize: $7.5 million from the X Prize Foundation. Unfortunately for X Prize followers, the New York Auto Show is not shaping up to be much of a battlefield. There is one exception: On Thursday, EV Innovations will unveil the Wave, a curvacious plug-in electric two-seater that the company claims will have a range of up to 200 miles, a top speed of around 80 mph, and start just north of $30,000 when it becomes available to consumers in 2010.

Editor’s Note: Our friends at Popular Mechanics have written an in-depth piece about an essential piece of fuel-saving technology: the turbocharger. Read the rest of this story at PM.

In the 1980s, it was difficult to escape the turbocharger. The twin energy crises of the 1970s forced automakers to produce cars that delivered better fuel economy. And that meant downsizing engines. By the 1980s, turbo technology was evolving and automakers installed them to boost the power of these smaller engines. But turbos promised more than just power—they promised fuel economy benefits too.

They sure can. Although the old-fashioned incandescent bulb measured slightly brighter than the equivalent CFLs, the test subjects in the Popular Mechanics study couldn’t see any significant difference. In fact, when it came to the overall quality of light, every single CFL scored higher than the incandescent: “In other words, the new fluorescent bulbs aren’t just better for both your wallet and the environment, they produce better light.”

To track the results, PM used a Konica Minolta CL-200 chroma meter to measure color temperature and brightness, and a Watts Up? Pro ammeter to track power consumption. They performed a double-blind test with three Popular Mechanics staffers and a lighting expert from Parsons The New School for Design in Manhattan. They put the participants in a color-neutral room, turned on the light, and asked them to examine colorful objects, faces and reading material, then rate the bulb’s performance.

The N:Vision Soft White bulb got the highest score of an “A.” The study found it to be “one of the top bulbs for reading and illuminating faces, the best-in-test N:Vision was noticeably ‘slow to warm.’ Still, it was ‘nice, pleasing and good overall.” The N:Vision has an average cost of $5.97 each.

CORRECTION: I had previously noted that the Sylvania Double Life Soft White was the lowest rated CFL. This is incorrect: The bulb is not a CFL but the incandescent against which the other CFLS were measured. It received the lowest score of all bulbs.

The lowest rated CFLs were the GE Soft White (which produced “accurate” color but made details hard to distinguish) and the Westinghouse Soft White (which was an average scorer overall but hurt one person’s eyes while reading). Both bulbs earned a B+.

I regret the error.
