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 C-Class Coupe to debut in Frankfurt

Mercedes-Benz is set to launch its new C-Class Coupe at the Frankfurt Motor Show this fall, according to Autocar. In addition to the standard C Coupe, the German automaker will also reportedly show a Mercedes-AMG C63 version, which AMG boss Tobias Moers says will be a "breakthrough" for the brand. Speaking to Autocar, Mercedes design chief Gorden Wagener promises the new C-Class Coupe will be "even better to drive than it looks," and says that the two-door will be sleeker and even more beautiful than the recently launched S-Class Coupe. Talk about a tall order. Specific design tweaks for the C Coupe will include revised front- and rear-end styling, while keeping the C's long hood and short rear deck to emphasize its rear-wheel-drive architecture. What's more, this revised design will need to be flexible, as Mercedes is planning a convertible version of its C-Class. Expect the interior design to carry over largely unchanged. The same goes for powertrains, including the excellent, twin-turbocharged, 4.0-liter V8 that will slot into the range-topping Mercedes-AMG C63 Coupe. We'll know more when the sleeker, two-door C-Class is unveiled in September.

2015 Mercedes-Benz SLK250 Quick Spin [w/video]

We car writers tend to have a occupationally limited focus. Autoblog's stock in trade is automotive news and new car reviews, which often steers us towards forgetting existing models about 17 minutes after we've driven it a second time. You guys like reading about the new hotness, too, so it tends to work out. But the wonderful fact is that every car sold today will have a rich/interesting/heroic/tragic life for years to come. And, occasionally, even obsolete makes and models stay interesting. That was my thinking when this 2015 Mercedes-Benz SLK250 came into our fleet. Set to be replaced with the SLK300, with that car's 2.0-liter turbo'd engine, the 250 is already running out the clock in Mercedes dealerships. What's more, my test car came complete with – are you ready for this? – a six-speed manual transmission. I can't tell you the last exact model of Benz that I'd driven with a stick shift, but I can assure you that its engine was carbureted. Considering the odd spec and replacement timeline, my question, as I drove the SLK for a week: was this a unicorn destined to be a driver's dearest find? Driving Notes: Let me not bury the lede any more: the six-speed isn't a game changer for the SLK. Yeah, over the course of a few days I came to be comfortable with the slightly vague clutch and notchy shifter, but I didn't love it. I went blasting on a few back roads, and found the hand-shaker more involving to use than the standard auto, but it was long to throw and not overly precise when I moved up and down between second, third, and fourth. On the other hand, the old 1.8T under the SLK250's bonnet still felt well matched with the base SLK's boulevardier mission. Output of 201 horsepower and 229 pound-feet of torque doesn't give enough gumption to move the hardtop German lump with authority, but it was still enough to be quick off the line and offer easy highway passing. The turbo four didn't sound bad under full throttle, either, but it did rattle like old plumbing when idling in the driveway. Speaking of rattling: the adjustable and Airscarf-equipped seats did a lot of it. (Airscarf, you'll recall, is M-B's brand name for an in-seat fan that blows hot air on your neck; it's nice on a cold day.) Though comfortable and mildly bolstered, the driver's chair made all kinds of funny noises when I got in, got out, or cornered over 20 miles per hour. That's rough for a luxury car with 6,000 (or so) miles on it.
