A burgeoning small car market in the U.S. convinced Mazda to finally sell its tiny Mazda2 here. The car, available around the world since 2007, will be shown in U.S. spec at the 2009 Los Angeles Auto Show. It joins the Honda Fit, Toyota Yaris, Scion xD, and Kia Soul in a subcompact market that has seen increasing sales.
The U.S. spec Mazda2 will get a 1.6-liter four cylinder engine mated to a five speed automatic transmission. Cabin tech offerings will be minimal, although a Bluetooth phone system should be present, along with audio controls on the steering wheel.
The 1.6-liter engine is the biggest offered in its world-wide marketing, with smaller powerplants also available starting at a 1.3-liter engine. Diesel engines are also in the mix, along with manual and continuously variable transmissions. In Japan, the car can also be optioned up with navigation, something that won't be available here.
Check out our upcoming coverage of the 2009 Los Angeles Auto Show for full details on the U.S. Mazda2.
The autonomous Audi TTS makes test runs on salt flats.
(Credit: Volksagen)The Defense Advanced Research Projects Agency (DARPA) conducted its autonomous vehicle races, the Grand Challenge and the Urban Challenge, in 2005 and 2007, but Volkswagen is still researching the technology. A combined effort with Volkswagen's Electronics Research Laboratory (ERL), Stanford University's Dynamics Design Lab (SDDL), and Sun Microsystem's resulted in the autonomous Audi TTS. The group working on the car is considering a run up the 12.4-mile Pikes Peak Hill Climb course in 2010 to demonstrate the capabilities of its driverless technology.
This new robot car is based on a 2009 Audi TTS, the sport version of the TT coupe. This car has Quattro all-wheel-drive and is motivated by a turbocharged, direct injection, 2-liter, four-cylinder engine producing 265 horsepower and 258 pound-feet of torque. ERL fitted this car with the sensors, servos, and drive-by-wire equipment necessary for computer control, while SDDL developed the programming so the car can respond appropriately to sensor data. Sun built the computer platform to run the car.
Past autonomous cars from Volkswagen, developed by Stanford, have been a Touareg SUV and a Passat wagon. A video promoting the new Audi TTS shows the technology has progressed so that it can handle drifting and cross-turning the wheels, maneuvers necessary for any speedy run up Pike's Peak.
While this technology could lead to commutes and long freeway trips where you could sit back and let the car do the driving, the point of the current research is developing new safety technologies.
So far, Audi's odd-numbered cars have been pretty desirable. The A3 is a practical and sporty little wagon, while the A5 is one of the better-looking cars to come out recently. But now Audi is replacing the A4 Cabriolet with a convertible version of the A5. Gone is that gracefully sloping roof, replaced by what is basically an umbrella, albeit one with acoustic damping built in to lessen road noise.
But Audi does equip the 2010 A5 Cabriolet with plenty of tech, including a navigation system with absolutely beautiful 3D maps. The drive technology is also interesting--it features a direct-injected turbocharged four cylinder, which strangely doesn't deliver on its promise of power and fuel economy.
After driving hundreds of cars to evaluate automotive technology, we've settled on our top 5 car technologies. Amongst the many, many features different automakers are making available, these are the ones we've found the most essential for everyday use. Some of these technologies can be found on most new cars today, while others are rarer, only offered by a few automakers. Some of these technologies will keep you and others safer, some will save you money, and some will just keep you happy.
That's strange, I thought a V-10 engine would be a bit bigger than this...
(Credit: SoundRacer)Have you ever caught yourself thinking, "I wish I had a V-8?" Well, what if I told you that you could give your crappy car a V-8 rumble or even a V-10 scream for $40? Now, what if I told you that you wouldn't actually be getting any extra performance to go along with that sound? If you're still interested in this shady deal, then you're probably a poseur. In any case, you'll want to check out the SoundRacer.
The device plugs into your vehicle's cigarette lighter, where it uses fluctuations in the power flow to calculate your engine's RPM. It then broadcasts a fake engine note to your car's stereo via an FM transmission. The general idea is for your vehicle to sound like it's powered by a V-8 or V-10 engine, but I predict that the outcome will probably sound like a crappy, fake revving played through crappy speakers on top of your car's already crappy existing engine note. Of course, your mileage may vary.
The best part is that if you keep your windows rolled up, no one will know that you're riding around pretending to be driving a V-10 Aveo. Nice!
Once you get bored with "the thrilling sound of a powerful Super Sports Car engine," you can plug your MP3 player into an auxiliary input and use the SoundRacer as a standard FM transmitter. The SoundRacer has an MSRP of $40.
Check out the embedded video for a demonstration of the SoundRacer V-8 and V-10 in all of their goofy glory.
This radio-controlled model car is powered by a battery that can be refilled with an electrolytic fluid.
(Credit: Fraunhofer Institute)Imagine that you're driving your future electric car down the road, and it gives you a low battery warning. What do you do? Instead of spending a few hours at a recharging station, new battery technology being developed by the Fraunhofer Institute in Germany would let you pull into a service station and refill the battery with an electrolytic liquid.
The Fraunhofer Institute is using a redox flow battery, a type of cell that uses two electrolytic fluids exchanging protons through a membrane. This process generates electricity. Although this type of battery isn't new, the Fraunhofer Institute improved the energy density, making it equivalent to that of a lithium ion battery.
In production cars such as the Tesla Roadster, the lithium ion battery pack requires almost four hours from a quick charger to go about 200 miles. A redox flow battery service station would pump out the discharged electrolytic fluid from your car's battery, replacing it with charged fluid, most likely in a matter of minutes. Instead of getting new shipments of charged fluid, similar to how current service stations rely on tankers full of gasoline, the station could merely recharge the fluid on its premises, even using solar cells or a wind turbine.
Other companies are working on redox flow battery technology for stationary energy storage.
For 2010, Tesla updates its electric Roadster with a Sport version, featuring faster acceleration.

Tesla often emphasizes that it works more like a Silicon Valley technology company than a traditional car company. And the company just proved it by delivering a model update to the Tesla Roadster for 2010. Remember, the Roadster has only been in production for one year, but in that time Tesla completely redesigned the interior, while at the same time adding new materials to reduce cabin noise. Model updates from other automakers often take five years.
We spent a day with the 2010 Tesla Roadster Sport, enjoying its unique driving experience and finding these updates made the previous generation car seem like something hacked together in a garage. Where the previous car had a fussy little lever for putting it in drive, the new car uses push buttons. To check battery statistics and change the drive mode, you had to use a touch screen by your left knee. That touch screen has been moved to the center of the dashboard. And in a real step toward convenience, the Tesla Roadster now comes with a glove box.
The rear air intakes get clear coat carbon fiber inserts.
(Credit: Josh Miller/CNET)Externally, the casual observer won't see much difference. The Tesla Roadster uses the same Lotus-sourced body clad in carbon fiber. But the carbon fiber stands out more, as clear-coat panels make up the hood, spoiler, and even the insets in the rear air intakes. The suspension is now adjustable for comfort or sport, and the all-new Sport version of the Roadster uses an upgraded power train that rockets it to 60 mph in 3.7 seconds, faster than the standard Roadster's 3.9 second time.

The big car audio companies chose to sit this round out. Fortunately, there was still a lot of cool tech at the 2009 SEMA Show.
(Credit: Antuan Goodwin/CNET)With the absence of the major car audio OEMs at the 2009 SEMA Show, it would be easy to assume that car tech has taken a backseat to tuning and muscle. However, the more compact electronics section allowed smaller companies with truly innovative products to shine. We found ourselves spending more time learning about cool products like the PowerSafe jumper cable, instead of rushing from booth to booth looking at amplifier after amplifier.
For example, On-Board Diagnostics (OBD-II) interfaces were a major part of the tech scene at SEMA. From add-on modules for your GPS device to standalone OBD-II devices to Wi-Fi dongles that transform your iPhone into a handheld diagnostics station, there were dozens of different devices that allowed users to listen in on what their vehicle used to only share with a mechanic. These devices allow tuners to search for more power, greenies to eke more miles out of a gallon, and regular consumers to feel more confident when they take their cars in for maintenance.
Other cool technologies that picked up awards were rearview camera interfaces, off-road iPod cradles, and a funny little device that actually makes all of those cupholders useful.
Check out our gallery of award-winning new products at the 2009 SEMA Show for more details and pics.

(Credit: Benoit Solivellas/CNET)Our colleagues in Paris got to drive Peugeot's BB1 concept car, a rare opportunity as concept cars usually get rolled out for display in a few auto shows, then never see the light of day again. The BB1 is small, designed as a city car, and runs on electricity, getting a range of 75 miles.
The BB1 includes an iPod dock mounted in the center of the steering wheel, which might prove to be a problem for the airbag. With an iPhone in the dock, the BB1 becomes Internet-enabled.
Before we drove it, the idea of an X5 M seemed outlandish, and we suspected BMW's motives had more to do with marketing than the company's engineering reputation. How could an X5 all-wheel-drive SUV live up to the M badge? We should have trusted BMW, whose engineers are so pure of heart they would never let a vehicle wear the M that didn't deserve it. The X5 M is a monstrously powerful beast that handles like a sports car. In fact, we had to drive up next to other cars for a height comparison to remind us we were in an SUV.
