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-Maybach Pullman stretches its way to Geneva

Mercedes-Benz is known the world over for producing luxury automobiles, but even among Benzes there's a hierarchy. The S-Class sits at the top of the Mercedes range, the Maybach at the top of the S-Class, and what you see here sits at the top of the Maybach line. It's the new Pullman limousine, and it arrives on the 50th anniversary of the original. Stretching a massive 21.3 feet, the new Mercedes-Maybach Pullman is even longer than the previous Maybach 62 by a full foot, and a good 3.5 feet longer than the standard-wheelbase Mercedes-Maybach S-Class, or two feet longer than the G63 AMG 6x6. In other terms, it's over a foot longer than the Rolls-Royce Phantom EWB, and the better part of a yard longer than even the Cadillac Escalade ESV. Heck, you could just about fit Benz's other flagship, the Mercedes-AMG GT, inside the new Pullman's 14.5-foot wheelbase. As if that's not enough, it also stands 3.9 inches higher than a standard S-Class to the benefit of its imposing presence and interior space. Should you be so fortunate as to be graced with an invitation to step inside, you'd find an interior entirely clad in leather with four seats: two recliners and two fold-down seats facing backwards. Those principal rear seats can recline between 19 and 43.5 degrees and offer an extensive array of individual adjustments to cater just-so to the occupants' individual preferences. Ingress and egress are enabled by larger rear doors that open in front of – instead of next to – those rear seats to enhance the privacy of the traveling dignitaries, who will be able to monitor the state of affairs through the analog thermometer, speedometer and clock mounted in the roof liner. They'll also enjoy privacy thanks to the electrically operated glass partition wall with an 18.5-inch monitor mounted in front of it and a choice of Burmester sound systems. Long the favorite of heads of state and captains of industry, the new Pullman will be unveiled at the Geneva Motor Show now just weeks away. We don't doubt that Mercedes will offer its customers a choice of engine options (as long as they're capable of motivating the new Pullman's assuredly substantial heft), but most suitable to the task will of course be the 6.0-liter twin-turbo V12 with its 523 horsepower and 612 pound-feet of torque.

The 2016 Spanish Grand Prix flipped all the scripts

The Monaco Formula 1 Grand Prix circuit and the Hungaroring fly the flag for processional races, yet Spain's Circuit de Catalunya is arguably as bad. Before this weekend, the pole-sitter won the race 19 times out of the last 25 years. The front row of the grid produced 23 winners in the past 25 years. The racing gods edited that script this year, when a first-lap crash and two mid-race strategy changes kept things open until the end of the 66-lap race. It started when Mercedes-AMG Petronas teammates Nico Rosberg and Lewis Hamilton took each other out on Lap 1. After Rosberg passed pole-sitter Hamilton into Turn 1, Rosberg's car slowed through Turn 3, somehow in the wrong mode. Hamilton closed in on Rosberg so quickly that once the Brit ducked inside for the pass, he couldn't back out. Rosberg, however, closed the door so suddenly that Hamilton had no choice but to drive onto the grass. When Hamilton spun, he collected Rosberg and both Mercedes' ended up in the gravel trap. The stewards deemed it a racing incident. The crash put Red Bull teammates Daniel Ricciardo and Max Verstappen in the lead, followed by Toro Rosso driver Carlos Sainz and the Ferrari duo of Sebastian Vettel and Kimi Raikkonen. Both Ferraris cleared Sainz by Lap 10, leaving 56 laps for them to haul in the Red Bulls. Ferrari loosely followed Red Bull's pit strategies. Ricciardo pitted on Laps 11 and 28, Vettel pitted on Laps 15 and 37. Verstappen pitted on Laps 12 and 35, Raikkonen pitted on Laps 13 and 36. Pirelli predicted a three-stop race as the fastest and that the medium tire could only go about 23 laps. Verstappen and Raikkonen didn't get those memos. So while Ricciardo and Vettel came in for third stops the Dutchman and the Finn stayed out, with Verstappen ahead of Raikkonen at the front of the race as of Lap 43. That's when Verstappen – 18 years and 227 days old – proved how good a driver he is, lapping perfectly as second-place Raikkonen closed the gap to a little more than half a second. The Finn still couldn't get past the Dutchman down the pit straight even with the help of DRS, nor under braking at the only real passing opportunity into Turn 1. At the end of Lap 66 Verstappen crossed the line ahead of Raikkonen, a victorious end to Verstappen's first race weekend after being promoted to Red Bull. Further back, Vettel and Ricciardo fought for scraps, the German staying ahead to finish third.
