Thirty different auto manufacturers and technology companies are partners in a group called Car 2 Car Communication Consortium. The point is to create cars that talk to each other -- but instead of swapping secrets only with other cars of the same brand, the group wants to create vehicles that can speak to any other car, truck, or motorcycle on the road.

In the land of mergers and acquisitions, there are takeovers, there are hostile takeovers, and then there are I'm Gonna Git You Sucka No Matter What takeovers. Porsche's increasingly acrimonious battle to swallow VW is becoming that third option, and the brawl might threaten the short term plans of Porsche, VW and Audi. Porsche wants access to Audi engines and electronics, but VW, which owns more than 99-percent of Audi, won't allow it.

Volvo has its locusts, Nissan has its bees. With 300-degree vision via compound eyes and instantaneous reflexes, bees don't run into things the way cars do. Nissan wants to halve the rate of car crashes by 2015, versus the company's 1995 tally, and is using bees to come up with a new generation of crash-avoidance systems that will be able to respond to obstacles in ways superior to humans.

Those wacky kids in Japan can do all kinds of things with their cell phones that those of us in the U.S. can't. Thanks to Nissan, Sharp Corporation, and NTT DOCOMO, the Japanese mobile communications company, they can now add car control to the list of possible cell phone features.

The phone uses the two-way communication of Nissan's Intelligent Key System, the same thing you use on your G37. For now, it can only lock and unlock the car and start and stop the engine, but if it takes off we imagine they'll add other options later. This is about convenience, not necessarily about sense -- if your phone gets stolen, that makes your car one more thing that the villains can abscond with.

FasTrak is an "electronic toll collection system" used in California. Once you set up an account, you get a transponder that simply debits your account balance whenever you pass through a toll booth. The system uses RFID technology to broadcast your account information to the toll booth receivers. According to Hack A Day, the system is anything but secure.

The rapidly shrinking US auto market has left automakers scrambling for any way to differentiate their products from the competition, and the fastest way to get the job done is with technology. Microsoft is all too aware of this, and the tech giant is betting big on automotive to give itself a larger presence in a rapidly growing field. Microsoft has increased both staffing and funding by 30% in an effort to get in on the connectivity and infotainment ground floor. Sync has been Microsoft's crowning achievement in the automotive space to date, with over 200,000 units sold so far and 1 m expected by the end of 2009.

Following two incidents in two weeks, it looks like the ballyhooed KERS hybrid system might not make it onto Formula 1 cars for 2009 -- at least, not the first races. Teams have begun to talk about how much difficulty they're having in building a safe system. KERS not only needs to work when the car is racing around the track, it also needs to be engineered properly in the event of a 300-kph accident.

We've heard it before: "We're going to collect the information, but it won't go beyond..." The latest take on "Let us help you with technology" comes courtesy of GM's OnStar, which is offering you the opportunity to have your annual mileage tracked. The info will be given to their GMAC arm, which will then see if you qualify for insurance discounts. That sounds good, right?

Of course, no one mentions the other side -- that they can also see if you need a higher premium. "You told us this car was just for weekend recreation, Mr. Smith..." Signing up for the OnStar service is voluntary, so it's not going to start watching you until you say so... yet. But if you really do think you're paying too much, then why not. They probably already know everything about you, anyway... Thanks for the tip, Myles!

Honda and Nissan are looking for ways to make cars lighter, better, and more recyclable, both for their own benefits and their customers. We've heard about the increased use of aluminum to save weight; next on the heavy R&D frontier could be carbon fiber. Both companies have teamed up with Japanese carbon fiber company Toray, and Mitsubishi Rayon -- a Japanese version of DuPont -- to research new, less expensive carbon fiber for cars.

Their efforts will be helped by the government, which is injecting two billion yen into the project over five years. The plan is that by the middle of the next decade, they'll be able to mass produce a cost effective carbon fiber and use it to reduce the weight of cars by 40-percent. And when they're finished with it, they will also be able to recycle it to reduce production costs.

Toyota's Crown Hybrid gets brownie points for good gas mileage, but it's apparently a troublemaker in the motor noise department. Instead of merely adding insulation to the bulkhead, Toyota engineered an Active Noise Control system to reduce engine noise inside the cabin.

The contraption uses three microphones on the interior of the car to detect engine noise. Based on the frequencies they detect, one speaker in each of the front doors and a woofer on the rear shelf create antiphase signals to cancel out the noise. The canceling is set up to occur at passenger head level, and does not interfere with the music system or your own talking.
