Cadillac pushes pedal on self-driving car

A self-driving car doesn't necessarily mean handing the keys over to a robot.

General Motors' on Friday said it is testing semi-autonomous technology on its Cadillac cars called Super Cruise that takes over freeway driving. It could be available by mid decade, the company said.

It's a sign how the technology for autonomous vehicles is advancing rapidly and how what's called a "self-driving car" can take different forms.

GM said that two of its 2013 Cadillac luxury sedans, the XTS and the ATS, have a Driver Assist package that already incorporates a number of sensors … Read more

Seeing red? Future Toyotas will sense your mood

Toyota is working on a mood-sensitive electronics system that's part safety net, part backseat driver. According to an article on Whatcar.com, the prototype system customizes the safety system's alert times based on the driver's mood. And how can it tell what mood you're in? Cameras mounted inside the cabin are focused on the driver's position and recognize emotions by interpreting 238 points on the face.

Sad or angry drivers may be distracted or have delayed reaction times, and they may not be able to avoid an accident. If your car thinks you've woken … Read more

Italy to launch Ferrari-style high-speed train

Next time you're stuck in traffic on the highway, consider those lucky Italians. Some will get to ride in style next week when services on the slick Italo high-speed train kick off.

Operated by Nuovo Trasporto Viaggiatori (NTV), the Italo debuts April 28 and will connect Milan, Rome, and Naples. It's being billed as the most advanced train in Europe.

It has a top speed of 186 mph -- not the fastest in the world but still respectable. The record for fastest commercial service depends on several factors, but Shanghai's Maglev Train can run at 268 mph. … Read more

James Bond/Batman boat is anything but a prop

A superyacht worthy of a James Bond supervillain -- or even of Batman's Bruce Wayne -- launched for the first time recently when the $15 million Adastra took a test drive on the Pearl River in Zhuhai, China.

Commissioned by Hong Kong shipping magnate Anto Marden, who owns and cruises to a pair of islands near Indonesia, the craft is based on the design of speedy Batboat-like "power trimaran" vessels such as the Earthrace and the Cable and Wireless Adventurer. But unlike those boats, the Adastra -- as you'll see -- was meant to be a luxury yacht, which, according to design firm John Shuttleworth, called for some new thinking.

Hybrids can be less polluting than coal-powered EVs

A study has found that cars with very high gas mileage are less polluting than electric vehicles charged up in coal-heavy regions.

The Union of Concerned Scientists released a report today called "State of Charge" that finds that on average plug-in cars are less polluting than gasoline-powered vehicles in the U.S. But the greenhouse gases emitted from electric vehicles depends on the sources of electricity.

The study centers on a heated discussion in auto circles. Automakers have sometimes referred to electric vehicles as "zero emissions," which is misleading because most plug-in drivers charge their cars … Read more

IBM brings smart charging to Honda Fit EVs

To a computer company like IBM, plug-in electric vehicles just look like more nodes on the network.

IBM tomorrow is expected to announce a demonstration project with Honda and California utility Pacific Gas & Electric to charge a fleet of Honda Fit EVs without disrupting the grid.

The smart-charging project will also test smartphone and Web-based apps for consumers, giving them an estimate of charge time and location of charging stations.

The power grid as a whole has the capacity to accommodate millions of plug-in vehicles, say experts. But if there's a concentration of electric cars charging at once, … Read more

Going my way? Zimride matches drivers, passengers (video)

Taking a trip but don't want to drive by yourself? Ride-sharing startup Zimride enables drivers to sell empty seats in their cars. For passengers, it means buying a ride with someone already going where they want to go.

Zimride launched on the campuses of Cornell University and the University of California at Santa Barbara in 2007. It has expanded to more than 100 college campuses, but it's also now available off campus too. Trips are typically 50 to 500 miles, and San Francisco to Los Angeles is the site's most popular route.

Being able to establish trust … Read more

Well-heeled travelers tired of airport lines have some good news today from Terrafugia.

The maker of the Transition flying car said that a production prototype, the D2, made its first flight earlier in March, a step toward what it hopes will be commercial availability within the next year. Company engineers took the Transition for an eight-minute flight around Plattsburgh International Airport in Plattsburgh, N.Y.

Amory Lovins: Cars need to go on a diet (video)

We Americans aren't the only ones who have gained weight. Over the past 25 years, our cars have gotten heavier too, says Amory Lovins.

Lovins, chief scientist of the Rocky Mountain Institute, says he believes that ultralight materials like carbon fiber composites can make cars simpler and cheaper to build. At the Cleantech Forum in San Francisco this week, Lovins talked about strategies to make oil-free automobiles.

This video originally appeared on SmartPlanet with the headline "Amory Lovins: Carbon fiber cars would cut oil dependency."
