Nissan's all electric Leaf goes into mass production next year.
(Credit: Josh Miller/CNET)Automakers tend to agree that the electrification of the car is inevitable, but Nissan is leading the way by readying a mass-market, affordable electric car for production. The Leaf is a midsize hatchback with a range of a little more than 100 miles, according to Nissan. Although Nissan didn't let us drive it, the company brought the Leaf to CNET's headquarters so we could get a close look at what might be the future of driving.
When Nissan first released pictures of the car, commenters found it ugly, with its bulbous headlights giving it a frog-like appearance. But in person, the length of the car mitigates that criticism. And looking over those headlights, we could see that they are longer, and more fin-shape than bulbous. The lights are LEDs, used because of their low power draw. The shape of the headlight casings has an aerodynamic purpose, splitting airflow around the side mirrors.
A hatch in front of the car conceals two plug-in points, one a standardized socket for electric vehicles and the other a proprietary Nissan design that can charge the batteries to 80 percent in 30 minutes. The Nissan plug, which would only work with very specific charging stations, uses DC power so that the onboard inverter doesn't have to convert external AC power for the DC batteries. The standardized plug will work with more sources, taking AC power from the grid and running it through the inverter, lengthening the time it takes to charge the batteries.
Nissan developed the lithium ion batteries for the Leaf in conjunction with NEC. The batteries are flat slabs that fit in the chassis of the car. Weighing about 500 pounds, the battery placement and distribution helps to lower the Leaf's center of gravity. Beyond charging from a plug, the Leaf also incorporates regenerative braking. Similar to the Tesla, as soon as you lift off the accelerator, regenerative braking kicks in, sending juice to the batteries and slowing the car.
The Nissan Leaf goes on sale in December of 2010 as a 2011 model. Nissan is counting on 20,000 preorders for the car, and will initially build them in Japan. By the third model year, the company expects to start producing them from its plant in Smyrna, Tennessee.
BMW's new 5-series incorporates many tech updates.

BMW released full details and photos of the new, 2011 5-series, representing a pretty significant update to the company's midsize sport-luxury sedan. An entirely new platform was developed, and is now shared between the 5-series and the new 7-series. The 550i model and 750i also share a power plant, a twin turbo 4.4-liter V-8. In the 550i, this engine produces 407 horsepower, bringing the car to 60 mph in 5 seconds. Other U.S. models are the 535i, powered by the same twin turbo 3-liter straight-six as the previous model, and a 528i.
The new 5-series serves as a platform for a host of driver aid technologies. Lane Change Warning alerts you to other cars in your blind spots while lane departure warning lets you know when you're drifting across lane lines. A night view system shows an enhanced display of the road on the LCD when it's dark out, and includes a pedestrian detection feature. Adaptive cruise control lets you set a cruising speed, and have the car slow down to match speeds with slower traffic ahead.
One of the more surprising driver aid features is automated parallel parking. This system is made possible by BMW's adoption of an electric power steering module for the 5-series. It uses sonar to determine if a parking space is long enough for the car, then automatically steers the wheel as you handle the gas and brake.
The 5-series gets the latest version of iDrive, but BMW is actually making it standard on all models. That means you get an LCD in the car whether you've chosen the navigation option or not. Without navigation, the LCD is a little smaller, and shows audio, phone, climate, and other car functions.
The Motorsports HD Hero comes packaged with a bunch of bits for flexible placement.
(Credit: GoPro cameras)On paper, the GoPro HD Hero is hitting on all cylinders. It's rugged, it's compact, and--to top it all off--it shoots in five modes of video (four of which are HD) and high-resolution still photography. But then you go to use it and things start to run a little less smoothly.
The HD Hero's weakest point lies with its thumbnail-size LCD screen and pinhead-size icons. With only two buttons and a cryptic menu system, the Hero's options screen probably shouldn't be tackled without an instruction manual close at hand. How else are you supposed to know what odd abbreviations such as "ALL" or "DAT" are supposed to mean? (Here's a hint: one of them formats your media, the other is a more benign function.)
Fortunately, the GoPro HD Hero fixes a number of issues that we had with the previous Hero camera system (such as the finicky AAA battery pack), but does the good outweigh the bad? Check out our full review to find out.

One of the highlights of Android 2.0 has been the Google Maps Navigation app that delivers voice-guided turn-by-turn navigation on your phone for free. Until now, only Motorola Droid owners could take advantage of this sweet perk, but times they are a-changing.
On Monday, Google announced that its navigation app is now available for devices running Android 1.6 and higher, including the T-Mobile G1 and T-Mobile MyTouch 3G. While still in beta, the app provides voice-guided directions between two points, traffic information, and business searches.
This release also includes a new Layers feature that lets you overlay more information on the map, such as transit lines and Wikipedia articles about places, but it does not support the "Navigate to" voice command feature found on Android 2.0, so you'll have to input all your destinations using your phone's keyboard.
Google Maps Navigation for Android 1.6 is now available for download from the Android Market. Unlike other navigation apps or location-based services from the likes of TomTom, Garmin, and TeleNav, you don't have to pay a one-time fee or monthly subscription to use Google Maps Navigation. All you need is a data connection and you're good to go.
A U.S. version of the tiny Mazda2 goes into showrooms in 2010.

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.
