The picture above was taken today at the Automotive X-Prize event at the Michigan International Speedway, and it shows – in the simplest way possible – the goal of the competition: a car that gets more than 100 miles per gallon equivalent (mpge). The X-Prize was supposed to bring us the best, most efficient vehicle possible and award the winning team millions of dollars for developing it. While there's no question that the X-Prize has done a lot to further green car technologies,

It's not that difficult to find a motorcycle that's capable of managing fuel mileage of 75 miles per gallon or so. In fact, all you need to do is march into your local Kawasaki dealership and plunk down a few thousand bucks on a brand new Ninja 250. Right off the showroom floor, the littlest Ninja is capable of returning stellar fuel mileage while boasting a more-than-adequate top speed of just over 100 miles per hour. But what if you want even more?

Indiana's Bright Automotive is slowly but surely taking the Rocky Mountain Institute's lightweight hyper-efficient vehicle idea (read more here) and making it a reality. One thing that will stay the same, though, is the, ahem, idea. IDEA will be the name of the plug-in hybrid concept vehicle when it is unveiled in Washington, D.C. later this month. Clever, that means the car will be officially called the Bright IDEA.

Remember Doug Pelmear, the inventor and mechanic from Toledo, Ohio who claims that his late-80's Fox Body Mustang makes 400-horsepower and still manages to return 80 miles per gallon? Doug's back in Toledo's news and he's making the same claims as before. In fact, Pelmear's Mustang can run on ethanol and in so doing, he says, can get up to 110 miles per gallon equivalent. Apparently, Doug's claims have been met with some skepticism, which isn't really surprising considering that the claims seem

After reaching an agreement with the California Air Resources Board recently that would essentially see the Chevy Volt classed as an electric car, it appears GM has now also worked things out with the EPA. The automaker and the environmental protection agency have been discussing just how extended range EVs like the Volt should be tested to evaluate fuel consumption and emissions. The federal agency responsible for enforcing the emissions and fuel economy standards had wanted to treat the Volt l

This Friday you'll finally get your chance a General Motors executive where they hid the mythical 200mpg carburetor and the water engine. The latest edition of the series of online chats being held on GMnext occurs this Friday at 9am EST. The guest chatter will be Bob Kruse, Executive Director of Global Vehicle Engineering Hybrids, Electric Vehicles and Batteries at GM and the subject is "Why don't automakers make a 100mpg car?" If you're inclined to participate in the chat, you'll need register

Can you beat all the alternative fuels and hybrids with a whopping 100 miles per gallon? Well, that's what a company called Transonic claims. Transonic, based in Camarillo, CA, declares that 100 mpg is possible with a revolutionary injection system. It's a system, though, that you can't see yet. According to the company's webpage: "Transonic Combustion's core technology is highly proprietary and, thus, reviewable only under NDA Agreement"

Do you remember the Loremo? It was a project for a car that with sporty looks could deliver a diesel consumption of 2 liters every 100 km - that is 117 mpg. Not bad! Well, the first road-ready prototype will be introduced at the Frankfurt Motorshow in September and although some of the specifications of the car won't be the same as the production model, this model will be very close to it. The current fuel mileage figures were obtained with computer simulation, so the working prototype will real

I've observed with mild amusement the recent spate of stories in the mainstream media about fuel saving. Maybe you have too.
