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.

F1 Race recap: 2016 Russian Grand Prix same as it ever was

The three-year-old Sochi Autodrom that hosts the Russian Grand Prix combines beautiful scenery with a hallmark turn 3, a tricky turn 13, and two long DRS zones. So far, however, those haven't added up to exciting races after the first lap. Despite an in-race issue with his car's MGU-K, Mercedes-AMG Petronas driver Nico Rosberg aced the weekend with his first career grand slam: pole position, fastest lap of the race, leading every lap, and victory. Behind him, not much happened on the leaderboard after an incident-filled opening lap. The drama started at turns 2 and 3. Ferrari driver Sebastian Vettel lined up in seventh on the grid because of a five-place gearbox penalty, Red Bull's Daniil Kvyat sat next to him in eighth. Kvyat hit the back of Vettel's Ferrari in the braking zone for Turn 2, shoving Vettel into Daniel Ricciardo – Kvyat's teammate. Kyvat then clobbered the back of Vettel's car at the entry to Turn 3, spinning the German into the wall and out of the race. Kvyat probably regrets saying before the race that he would show Vettel "no mercy" on the first lap. At the back of the grid at Turn 2, Haas F1's Esteban Gutierrez hit Force India's Nico Hulkenberg and Manor's Rio Haryanto. Gutierrez continued, both the Force India and the Manor retired. A brief Virtual Safety Car period ensued, then the actual Safety Car emerged for three laps while marshals cleaned up the track. Mercedes-AMG Petronas driver Nico Rosberg nailed the restart and took off for the rest of the race. Teammate Lewis Hamilton battled his own gremlins all weekend but still finished second, 25 seconds behind Rosberg. During the final qualifying session on Saturday Hamilton's car suffered the same MGU-H failure as in China two weeks ago. The problem relegated him to tenth on the grid. In the race, Hamilton fought his way to second place by Lap 19 out of 53 laps and began closing the 13-second gap to Rosberg. On Lap 37, the gap now under eight seconds, Mercedes told Hamilton his car had a water pressure issue. The malfunction forced the Briton to manage his race and settle for second. Afterward, Hamilton said he was certain he could have won if not for the malfunction. The rest of the top ten barely changed throughout the contest. The first five positions on Lap 21 crossed the finish line in that order 32 laps later. Ferrari's Kimi Raikkonen took the final podium position ahead of the Williams duo of Valtteri Bottas and Felipe Massa.

2017 Mercedes SL gets more beauty, power, and equipment

The first gestation of the R231-generation Mercedes-Benz SL-Class was appreciably better than the excellent R230 it replaced, it just didn't look nearly as good. Answering for one of its rare design sins with a facelift for the 2017 model year, Mercedes succeeds in restoring the skin-deep glory the R231 SL deserved from the beginning. They didn't stop at the skin, either, giving buyers plenty of additional technical reasons to make the upgrade. The new design establishes its new beauty with the grille and headlights. The grille has essentially been flipped upside down - it is now wider at the bottom than the top. It is flanked by sleeker headlights pulled out to the edges, and now full-LED lights are standard. The front fascia below gets much more pronounced, especially on the AMG versions with their larger intakes and chrome-trimmed A-wing motif across the horizontal span. Brilliant Blue and Designo Selenite Grey Magno join the color palette. The SL400 becomes the SL450, its 3.0-liter twin-turbo V6 juiced up from 329 horsepower to 362 hp, and 354 pound-feet of torque to 369 lb-ft. Both it and the SL550 shed their seven-speed automatics for the new 9G-Tronic automatic. Inside, new designs for the gauge cluster look back at the driver, ambient lighting options have expanded to include polar blue and polar white, and the center console storage ambient lighting throw a brand logo on the two USB ports fitted inside. The roof can be opened at up to 25 miles per hour now, and the trunk separator automatically gets out of the way when you put the top down - no more having to do that yourself beforehand. Turning the page on performance, non-AMG models come offer Mercedes' curve-tilting function with Active Body Control. It counters cornering forces by tilting the body up to 2.65 degrees into a turn; choosing it removes the Eco function from the five Drive Select modes, replacing it with Curve mode. The AMG SL63 and SL65 models come with a mechanical rear differential lock standard - formerly part of a $9,000 upgrade package, an updated seven-speed transmission, and faster shifting via aluminum shift paddles. We'll get looks at the AMG SL63 and SL65 at the LA Auto Show, the refreshed range hits dealerships in late spring next year. Mercedes has a lot to tell you in the press release below, so dig in.
