      "Zero Pollution Motors (ZPM) confirmed to on Thursday that it expects to produce the world’s first air-powered car for the United States by late 2009 or early 2010. As the U.S. licensee for Luxembourg-based MDI, which developed the Air Car as a compression-based alternative to the internal combustion engine, ZPM has attained rights to build the first of several modular plants, which are likely to begin manufacturing in the Northeast and grow for regional production around the country, at a clip of up to 10,000 Air Cars per year." 06-08

  4. Automotive X Prize (
      "PM's expert car editors have watched this $10 million competition from the beginning, test driving some of the most fuel-efficient cars in the world, following the first teams to sign up—even sponsoring one. Now, as gas prices soar and the AXP entry pool officially opens, we take a detailed look at the most promising startups. These are the innovators we believe at this point have a very real shot at winning the X Prize—and developing a mass-market 100-mpg vehicle. (We'll examine some of the race's unsung heroes soon.) Adhering to the X Prize Foundation's rules, we analyzed all 64 entrants thus far based on six factors—technological feasibility, fuel economy, design, performance, price and production reality. The result is the most comprehensive, up-to-date scouting report on the field for the ultimate car of tomorrow." 06-08

  7. Getting There Without Your SUV (CNN news)
      "If you drive a big SUV or pickup truck, you're probably trying to think of ways to save fuel, or -- gasp -- getting rid of that big vehicle and driving a fuel-efficient sedan or coupe."

      "But you probably bought that truck for a reason -- you need to carry people and or lots of stuff. Don't despair. There are options if you decide to ditch the behemoth." 09-08

  8. Hypermiling (
      "on a midsummer saturday in a sprawling wisconsin parking lot, about a dozen people are milling about a candy-apple red Honda Insight. They're watching Wayne Gerdes prepare for his run in Hybridfest's mpg Challenge, a 20-mile race through the streets of Madison. Wayne is the odds-on favorite to win the challenge, in which drivers compete to push the automotive limits not of speed and power—a desire those gathered here consider old-fashioned and wasteful—but for the unsexy title of Most Fuel-Efficient Driver in the World." 06-08

  9. Volkswagen's Diesel Polo--In Europe (
      "The Polo gets 60 to 70-plus mpg. And it’s really fun to drive. It’s got a good bit of turbo lag, so you need to keep the revs up for serious power, but once the turbo kicks in, acceleration is frisky. And the lag makes the car feel faster than it actually is. I didn’t wring it out, but over the course of a short cruise through the suburbs, it felt like a car I could gladly live with day in, day out. Fun to drive, just enough room for a family, and frugal as all get out. In Europe, the Polo sells for less than $20,000." 06-08

  10. Windows Up or Down? (
      "Automotive engineers have all the fun."

      "Or maybe not. During the test, one engineer shot around the track with the air cranked up. A second had the windows down. An unlucky third test driver was assigned to what turned out to be the most-fuel efficient way to travel: Driving with the windows up and the air conditioner switched off." 8-05

  11. World's Cheapest Car (
      "A lot is riding on the the world's cheapest car. In the words of Ratan Tata, chairman of the company behind the upstart econobox, India's "People's Car" will be a "safe, affordable, all weather vehicle for a family which is today traveling on a two wheeler." The entry level model is ticketed at just over $2,500 — or the equivalent of 100,000 rupees or one Lakh — a revolutionary price where the average lower middle class income is $200 a month. (For comparison's sake, in the early 1970s, Honda introduced affordable, good quality Civics at about $2,200, which adjusted for inflation would now be nearly $10,500.) It could well be one of the most important cars ever designed." 01-08

  3. A Review of the Volt (New York Times)
      "Here’s what really got me, though: on the dashboard, alongside the gauge that measures the battery life, the Volt has another gauge that calculates the vehicle’s miles per gallon. During the two-hour drive to Southampton, I used two gallons of gas, a quarter of the tank. Thus, when I drove into the driveway, it read 50 miles per gallon."

      "The next day, after the overnight charge, I didn’t use any gas. After driving around 30 miles in the morning, I recharged it for a few hours while I puttered around the house. (It takes 10 hours to fully recharge, unless you buy a special 240-volt recharging unit.) That gave the battery 10 miles, more than enough to get me where I needed to go that evening on battery power alone. Before I knew it, my miles per gallon for that tankful of gas had hit 80. By the next day it had topped 100. I soon found myself obsessed with increasing my miles per gallon — and avoiding having to buy more gas." 06-11

  21. Energy and Oil: Kerry (
      "I support updating CAFE standards to 36 miles per gallon by 2015. This proposal will reduce America's dependence on oil by saving 2 million barrels of oil per day -- almost as much as we currently import from the Persian Gulf. It will reduce greenhouse gas emissions, smog and ozone pollution."

      "We have to encourage the use of hybrid vehicles and invest in research and development. We have to set a goal by 2020 that 20 percent of our energy will come from renewable fuels. I am going to create an energy efficient trust fund to look for news sources of energy and we are going to create tens of thousands of jobs doing that. We can't drill our way out of this."

      "We only have 3% of the world's oil reserves. There is no physical way for the US to drill its way out of this problem. We have to invent our way out of this problem. The sooner that we commit America to the science & discovery of renewable alternatives, the better off America will be, the better our health will be, the more effective our economy would be, the better our national security will be, and the better world citizen we will be. We need to commit ourselves to energy independence now." 2-04

  38. Smart ForTwo Promised in 2008 (
      "These small-on-the-outside, large-on-the-inside rides, designed by Daimler (Mercedes-Benz), have been a hit in Europe for almost 10 years and will start rolling onto United States streets in January. The Smart Fortwo (as in for two passengers) will create a new, sub “B” car class in the U.S. market. It’s a vehicle specifically designed to comfortably and efficiently transport its occupants through the worst areas of urban congestion. The micro-size dimensions make it over 2 ft. shorter than a Mini Cooper. And at just over 5 ft. across, the Fortwo sits as wide as it does tall. You can park this Smart widthwise across a conventional parking space."

      "And since the Smart revs relatively high at freeway speeds, economy appears to plummet in proportion to speed more quickly than on some small cars. But drive, ahem, smart, and you’ll get 40 mpg in the city and 45 on the highway." 11-07
