Ford Green Zone works magic with GPS to make your drive smarter, cleaner

For the most part, plug-in hybrids rely on the power stored in the battery until that charge is depleted. Unless the switch can be changed manually, it's only then that the cars fire up the internal combustion engine and begin using the fossil fuels on board. This is ideal, of course, when one's drive isn't long enough that the car needs to start sipping gasoline at all. On longer commutes, when it's certain that the route is longer than the car's all-electric range, this isn't necessarily the most efficient use of energy. Ford's Green Zone system is designed to save some of that juice for the parts of the drive that require slower speeds. Ford is working on a smart system, based on Nokia mapping technology, that uses GPS data to use both the electricity and conventional fuel more efficiently. Since battery power is less efficient at highway speeds, Ford's Green Zone system is designed to save some of that juice for the parts of the drive that require slower speeds, rather than just using up all the electrons right at the beginning of the drive. Using a website or the in-car navigation system, the driver can pinpoint the parts of the route, highlighted in green, where using battery power would be more effective, and set the car to automatically switch to electricity for those sections. Depending on the route, the car could automatically switch back and forth between the two power sources multiple times, particularly if the drive is a mix between city and highway driving. Of course, Green Zone will be go beyond that. The program is being developed to take traffic and road grade into account, details that allow the car to be make even smarter choices to improve efficiency. Ford even hopes to have Green Zone learn driver habits, and respond accordingly depending on who is driving the car. The system could control other features as well, such as anticipating corners and shifting the headlights to better illuminate the road ahead. Green Zone could also potentially use information from vehicle-to-vehicle networking to control functions in the car. The Green Zone system still has a few years before it will be ready to be put into production vehicles, but Ford is confident it will make its way onto the road eventually. As with other innovations that improve efficiency and make our vehicles smarter, we can expect to see similar technology from other manufacturers, until it becomes a regular part of driving in the future.

Carfection looks for the ultimate pocket rocket

If there's one thing we love, it's a good showdown. Especially when it's on video, done by some Englishmen, and involving some manner of performance machinery. Like this latest clip, for example, from Carfection. The team formerly known as Xcar have assembled three very compelling supermini hot hatches: two we can get on our side of the pond, and one we can't. One American, one Frenchman, and one Brit. One cheap, one expensive, and one somewhere in between. They all pack turbo fours, of course, but placed in entirely different packages. There's the evergreen favorite Ford Fiesta ST, the Renault Clio RS 220 Trophy that should have the rest licked, and the retro rocket that is the Mini JCW. And there's only one way to find out which is the best. It's a tough contest, to be sure, but lest you think it all comes down to specifications or which one's the newest, you'll want to think again. Because when it comes to hot hatches, all the electronic gizmos and power boosts in the world can't show up a perfectly dialed-in chassis that lets you hug the curves and feel like you're going a lot faster than you actually are. But don't take our word for it – see what our British friends have to say about it in the Queen's English in the seventeen-minute clip above. Related Video:

American automakers fall in latest Fortune 500 rankings

Not that it means anything beyond bragging rights, but if you're fixated on the positions of domestic automakers on the annual Fortune 500 list, both General Motors and Ford are still on it but they've slipped a couple of notches. The list ranks American companies and they're ordered solely by revenue. GM, fifth last year, came in seventh, while Ford fell from ninth to tenth even though both companies saw small gains in annual revenue.
GM's $152.3 billion in revenue was less than a third of that of the first company on the list: Wal-Mart, which regained the title from Exxon Mobil. Berkshire Hathaway and Apple are the firms that moved GM down. Ford, displaced by energy company Valero, had $134.3 billion in revenue.
On a side note, profitability isn't a factor, but both GM and Ford were down in this year's list compared to last year's: GM declined from $9.2 billion to $6.2 billion, Ford fell from $20.2 billion to $5.6 billion. If profits were included, Exxon Mobil would probably still be king: although the energy company made almost $20 billion less in revenue than Wal-Mart's $469.2 billion, it posted $44.9 billion in profit compared to Wal-Mart's $17 billion.
