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.

Weekly Recap: Mercedes continues the pseudo-coupe craze with AMG-tuned CUV

But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. BMW proved there is a market for crossover utility vehicles designed to look like coupes – as much as a vehicle with four doors and noticeable ground clearance can look like a coupe, anyway. Now comes the reply from Mercedes-Benz: the GLE Coupe. The rakish crossover is a harbinger of things to come from Mercedes, as it begins the company's transition to a new nomenclature and marks the debut of the AMG Sport line. It also continues the recent coupe craze. Designers from many automakers, like Nissan and Volkswagen, have increasingly turned to swoopy, dramatic styling to make utility vehicles and sedans seem more desirable. By revealing the GLE 450 AMG Sport model first, Mercedes is clearly hoping to cast the GLE Coupe as a sportier, lifestyle-oriented alternative in its lineup of beefy crossovers and SUVs. Mercedes used the word "sport," or a variation of it, 53 times in its press release, so uh yeah, it's sporty. It's not an empty promise: Benz means business with the AMG Sport line. This GLE Coupe gets a 3.0-liter biturbo V6 rated at 362 horsepower and 384 pound-feet of torque paired with Mercedes' new nine-speed automatic transmission, and it runs with 4Matic all-wheel drive. Specs on the other GLE Coupe models were not disclosed. But as BMW's X6 has demonstrated, sport sells in in the crossover segment, and Mercedes is giving the people what they want. After all, more than 260,000 people have bought X6s since 2008, and Mercedes wants a piece of that. From certain angles, the GLE Coupe even looks vaguely like an X6. "This is really a vehicle that is all about status," said Dave Sullivan, product analysis manager for research firm AutoPacific. "You can buy a SUV that doesn't have the inherent qualities of a SUV, such as cargo hauling. People will likely be drawn to the looks. Coupes are all the rage." BMW, however, isn't running from the fight, and the updated 2015 X6 is arriving in showrooms this month. It also added a smaller sibling, the X4, to its coupe-crossover stable in July. The GLE Coupe arrives next year, though Mercedes hasn't specified exactly when it will hit showrooms from the factory in Alabama, or specified details on the rest of the non-AMG Sport models. In 2008, it was surprising the X6 was a hit. In 2015, it will be even more surprising if the GLE Coupe isn't.

2015 Mercedes-Benz S63 AMG Coupe

Conventional wisdom would dictate that adding more power and several key performance enhancements to an already very good car, like the 2015 Mercedes-Benz S550 Coupe, will end up equaling an even better car. In the case of the 2015 Mercedes-Benz S63 AMG Coupe, conventional wisdom sort of applies, but perhaps not as much as we'd have initially guessed. We'll get into the nitty gritty details in just a moment, but here's the most immediate takeaway we had in our minds as we walked away from this super coupe: The S63 AMG is excellent, but so is the slightly more mundane S550 Coupe on which it is based, and which is priced some $41,000 less expensive than its more powerful sibling. Chew on those figures while we examine what differentiates the two S-Class Coupes. Drive Notes As expected, the single greatest highlight of the 2015 S63 Coupe is its engine. As a powerplant, it's a gem. As a hand-built engineering exercise, its 577 horsepower and 664 pound-feet of torque are just as impressive in real life as they sound when recited from stat sheets. Not that the old CL63 AMG was lacking in power, but the new S63 AMG Coupe boasts 41 more horses and 74 more lb-ft than the outgoing engine. The run to 60 miles per hour takes a scant 3.9 seconds, according to M-B, aided in no small part by the car's 4Matic all-wheel-drive system and other assorted electronic brains deciding where, exactly, all those ponies should be sent. The rear-biased system is tuned to send two-thirds of the engine's power to the rear wheels in a bid to make the car feel more like what performance-minded drivers expect. Top speed is electronically limited to 186 miles per hour, which is plenty fast enough, even in the days of 200-plus-mph sedans from M-B's former corporate cousin Dodge. We didn't get anywhere near the car's maximum velocity, but our brief trips into triple-digit territory were quiet, comfortable and completely free of drama. The seven-speed automatic gearbox responds quickly to requests of your right foot, but the steering wheel-mounted paddles don't change gears as quickly as we'd like when in Manual mode. Controlled Efficiency (which we'd call Comfort) maximizes efficiency, keeping the transmission in higher gears and shifting earlier than when in Sport mode, and we didn't find much fault with the computer's shifting algorithms in either setting.
