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.

2016 German Grand Prix race recap: so-so racing, great questions

We can summarize the 2016 German Grand Prix in one sentence: Mercedes-AMG Petronas driver Lewis Hamilton started second on the grid, passed pole-sitter and teammate Nico Rosberg before the first corner, and dominate to the finish. In fact, Hamilton turned his engine power output down on Lap 3 and still took the checkered flag seven seconds ahead of Red Bull driver Daniel Ricciardo. Ricciardo's teammate Max Verstappen crossed the line another six seconds back. Rosberg fell to fourth at the first corner and couldn't find the pace to reel in the Red Bulls. His questionable pass on Verstappen didn't help when the stewards penalized Rosberg five seconds; the overtake reminded us of Rosberg's move on teammate Hamilton in Austria. That penalty turned into eight seconds when the Mercedes-AMG Petronas stopwatch didn't work in the pits. Ferrari pilots Sebastian Vettel and Kimi Raikkonen finished fifth and sixth. Those six drivers all started in the top six, too. Behind them, on Lap 28 of the 67-lap race the next four drivers were Valtteri Bottas in the Williams, Nico Hulkenberg in the Force India, and Jenson Button and Fernando Alonso in McLarens. Low fuel and old tires put the kibosh on Alonso's pace just four laps from the finish, allowing Force India's Sergio Perez to pass, rounding out the top ten. The issues up for debate during the four-week break are far more interesting than the weekend's race. As bad as Ferrari's day might have been – and we'll get to that – Rosberg probably took the biggest hit, losing the race before the first corner for the second weekend in a row and falling 19 points behind Hamilton. Rosberg won the first four races of the season, then the teammates tripped over one another in Spain. Hamilton's won six of the seven races since Spain, Rosberg's best result in that time is a second-place in Hungary. Hamilton turned his engine down on Lap 3 (!) because he's used his entire season's allotment of five turbochargers and five MGU-Ks. Those early-season gremlins now have him on edge of grid penalties. Unless Hamilton's momentum cools off in August, however, that reliability danger might be the only dent in his armor. Rosberg, who once led the Championship by 43 points, will surely drown in his thoughts – and maybe schnapps – over the summer break. Whatever the Italian word for "meditation" is, there'll be a lot of it at Ferrari during the F1 summer break.

New Mercedes Unimog debuts to the cheers of little boys everywhere [w/video]

The Mercedes Unimog, the superhero villain of the off-road world that's just waiting to make the jump to Transformer, has been completely upgraded for its new generation. There are ten models, expanding the range and getting new designations across the traditional all-terrain series and the implement-carrier series. Panoramic cabins get more visibility, multifunction steering wheels and better dash clusters, improved HVAC and a three-mode central tire inflation system. Outside, there are new items like LED headlights and daytime running lamps in the bumper, roof-mounted windshield wipers and a front-camera monitor for the implement carrier.
The new engine lineup is compliant with Euro VI, featuring four- and six-cylinder BlueEfficiency engines putting out anywhere from 156 horsepower to 354 hp. Powerplant placement has also been tweaked, the chassis members getting a revised curve to place the engine a bit further back and lower, maintaining off-road clearance and lowering the Unimog's center of gravity. The new location of the engine means the cabin has more room, and the wheelbase is shorter. Combined with a higher turning angle, the Unimog has a smaller turning radius than before.
The implement carrier gets what's called a "synergistic traveling drive," the bonus being that drivers don't need to stop in order to use an attachment - a hydrostatic transmission works with the regular manual transmission at up to 31 kilometers per hour for seamless switching.
