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.

Mercedes-Benz S-Class spied once again

As evidenced by how little camouflage the next-generation Mercedes-Benz S-Class has been caught wearing lately, it can't be too much longer until the car will get its official debut. In our newest shots of the yacht-sized luxo sedan, the cladding still covers up the headlights, front fascia and most of the rear end, but we finally have an almost undisguised look at the rest of the car's lines.
Considering previous spy shots had more camo that better (or fully) concealed the S-Class' body, some of the more obvious things we see in these images include the prominent grille, the CLS-Class-inspired bodyside creases, the pointed trunk opening and, most interestingly, a lack of fancy exhaust outlets. Unlike other S-Class prototypes we've seen, this car does not have integrated outlets, but it does have two pipes on the left side of the car. All current S-Class models in the US and Europe feature a dual exhaust layout on each side of the car, so while some of our questions about the car get answered, it would appear that more are just arising.

Recharge Wrap-up: Innova EV Car Share, Mercedes to use CO2 A/C

Innova UEV will launch its carsharing program at the Association for the Advancement of Sustainability in Higher Education 2015 Conference & Expo. Called Innova EV Car Share, the program is designed for college campuses, and uses the Innova Dash neighborhood electric vehicle and solar charging stations. "The Innova UEV team is excited to introduce this innovative sustainability program to universities across the country as a way to reduce CO2 output as well as decrease congestion," says Innova UEV Founder and CEO Roman Kuropas. "Visionary schools that make this level of commitment to the environment are sure to add to their sustainability prestige as leaders in higher education."

ABB chargers will connect to the Microsoft Azure cloud, allowing for smarter charging as infrastructure expands. "Platform performance and stability are critical differentiators for the successful operation of a modern, data-dependent EV charging station," says ABB's Pekka Tiitinen. "By partnering with Microsoft, ABB will be able to offer best-in-class operations as well as innovative advanced services - what we call the Internet of Things, Services and People." Perhaps we'll hear more specific details following the platform's launch at eCarTec in Germany. Read more from Microsoft. Honda is testing solar-powered EV charging in the Marshall Islands. The AC charging stations, called the Honda Power Chargers, will help power a fleet of Fit EVs on the remote islands as part of a pilot test. The Marshall Islands must import most of their energy supplies, so solar-powered mobility would help provide some self-sufficiency and cost savings. Honda, the Marshall Islands government, and the Japanese Ministry of Economy, Trade and Industry will use the experiment to determine if it would be worthwhile to expand the solar-powered charging infrastructure.

The European offerings of the S-Class and E-Class will be the first to use a CO2-based air conditioning system. The use of CO2 requires a redesign of much of the system, as it requires a much higher pressure than other refrigerants. The automaker will use the HFO-1234yf refrigerant in its other vehicles.
