Weekly Recap: Autonomous driving goes commercial in Nevada

Nevada granted Daimler Trucks North America the first license to run an autonomous commercial vehicle on public roads in the United States Tuesday, marking another milestone in the technology's rapid advancement. Gov. Brian Sandoval and Daimler truck chief Wolfgang Bernhard promptly used the license to lap Highway 15 near Las Vegas in a newly revealed Freightliner Inspiration Truck. It was a clear signal that autonomous driving is big-rig reality, though it's still a long way from widespread use. Nevada certified two of Daimler's Freightliner Inspiration Trucks, which use the company's Highway Pilot system with a stereo camera, radar, and lane-keeping collision-prevention features to regulate the brakes and steering. The radar component has a long-range sensor that can cover 820 feet at an 18-degree angle and a shorter-range unit that stretches 230 feet at a 130-degree angle. The Inspiration trucks are based on the existing Freightliner Cascadia Evolution model used on US roads. In addition to the autonomous technologies, it also has futuristic design cues, including blue lighting in the front and a new hood and grille. While there are only two Freightliner Inspiration trucks in existence, Daimler expects to bring the Highway Pilot system into mass-produced big rigs by 2025, in time to capitalize on the market's predicted growth. The German truckmaker predicts the global hauling market will triple by 2050, and the United States will be a key part of that growth. Trucks carry 69.1 percent the nation's domestic freight tonnage and hauled 9.7 billion tons of freight in 2013, according to the American Trucking Association. Daimler expects autonomous driving to augment this growth, and perhaps evolve the role of the truck driver. Still, the company points out autonomous tech is not meant to replace drivers, but to assist them and relieve fatigue and monotony on long hauls. The driver has to stay in control for passing, in city traffic, and when hooking up the trailer. The company said autonomous driving also offers the potential for improved fuel economy – tests showed a five-percent gain – and lower maintenance costs. Daimler also said the technology could reduce congestion on the road. Much of this is attributable to the constant flow of traffic, which is aided by autonomous driving. While the benefits are becoming increasingly apparent, autonomous technology is still met with skepticism.

Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.

Recharge Wrap-up: Detroit Electric teaser video, Nissan Leaf is Good Housekeeping "Tried and Tested"

Detroit Electric has a new teaser video and has updated its brand in preparation of the introduction of the SP:01. The refreshed logo uses a blue and white color palette, and the company has also given its website a new look. The teaser video, which gives a sneak peek at the exterior of the SP:01, shows the car taking form in the midst of an electrical storm. Watch the video or learn more in the press release below. Abengoa is celebrating the grand opening of a commercial scale cellulosic ethanol plant in Hugoton, KS. When running at full scale, the refinery will produce up to 25 million gallons of ethanol a year. The plant will also generate enough electricity to power itself and put some back into the grid. Energy Secretary Ernest Moniz was on hand for the dedication, saying, "Every gallon of cellulosic ethanol produced and used to fuel our vehicles reduces the impact of harmful greenhouse gas emissions by greater than 60 percent as compared to conventional gasoline." Learn more at Energy.gov. Good Housekeeping has named the Nissan Leaf one of its "Tried and Tested" vehicles. The magazine called the Leaf SL its top "Roomy Electric" vehicle in its November issue. The magazine's research institute evaluated the EV based on track and road driving, ergonomics and convenience features. Good Housekeeping made note of the car's "impressive" range, but according to Nissan's Fred Diaz, "the real beauty of the Nissan Leaf is that it's roomy and, best of all, fun to drive."

It uses things like grains leftover from brewing Budweiser, food waste from a baseball stadium and sewage sludge to produce the gas through anaerobic digestion. The compressed gas can then be used to power cars like Chevrolet's Bi-fuel Impala, which goes on sale later this year. Chevrolet likens the situation to the Delorean time machine in the Back To The Future movie series, which uses garbage to fuel its fusion generator.
