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.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

RideCell provides technology for services such as carsharing, ridesharing and other transit services. "The convergence of transportation trends in cities is of key importance to BMW," says Ulrich Quay, head of BMW i Ventures.

Mercedes raises the roof on new CLA Shooting Brake [UPDATE]

UPDATE: As we feared, the CLA Shooting Brake is not currently slated for US availability. The text below has been adjusted accordingly. Of all the variants in Mercedes' smallest line, only one doesn't have a liftgate, and that's the CLA-Class. But don't worry, the German automaker is out to fix that too with the reveal of the new CLA Shooting Brake you see here. Based on the same platform that underpins the CLA four-door coupe, the A-Class hatchback, B-Class minivan and GLA crossover, the new Shooting Brake applies a similar formula we've already seen on the bigger CLS Shooting Brake but in a much smaller form – which is to say, it's a wagon, but a shapely one. The revised roofline means more headroom in the back seat and significantly more cargo capacity than the four-door's trunk. Mercedes will offer the CLA with a variety of engine choices, including a 2.1-liter turbodiesel with either 136 or 177 horsepower, a 1.6-liter four with 122, 156 or 211 horsepower. That last model will even be available with 4Matic all-wheel drive for those not enamored by the idea of a front-drive Benz, but the top of the range, of course, is the CLA45 AMG Shooting Brake that carries the same 2.0-liter turbo four – all 360 horsepower of it – as the four-door CLA45 as well as the A45 and GLA45. Driving once again to all four wheels, Daimler says it'll reach 62 in 4.7 seconds (even quicker than the crossover) and top out at the usual 155 miles per hour. Of course those options only apply to markets where the new Shooting Brake will be offered. And unfortunately, Mercedes-Benz USA confirmed to Autoblog that (like the CLS wagon) the CLA Shooting Brake won't be making the transatlantic voyage to US showrooms (where the E-Class is the only low-slung Benz wagon on offer). That leaves the four-door CLA and the GLA crossover still holding down the pint-sized fort for Mercedes. THE NEW MERCEDES-BENZ CLA SHOOTING BRAKE: SPACE FOR SOMETHING NEW Stuttgart. Breathtakingly sporty proportions and a powerfully dynamic design idiom with sensuously shaped surfaces already made the CLA unmistakable in its four-door Coupe guise. It is now followed by a further design icon, the CLA Shooting Brake, with a unique look all of its own. The lower overall height and the elongated coupe-style roof contour line, the low greenhouse and the sweep of the high beltline are the key design features of its distinctive profile.
