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.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...

2015 Mercedes-Benz GLA250 4Matic Quick Spin [w/video]

Certain expectations come with the name "Mercedes-Benz." We picture cars with luxuriously appointed interiors, fashionable exteriors, Autobahn-worthy performance, and a ride that delivers an optimal balance between agility and outright comfort. Expectations, though, are no friend to the GLA250. This is a car that is deeply confused as to its purpose in life – can it be a proper Mercedes-Benz while still being a reasonably priced, subcompact crossover? After a week behind the wheel, we believe the two are mutually exclusive. Driving Notes The exterior styling is similar to the not-for-America A-Class hatchback, with the only major differences found on the rear end. That means that even with its flashy 19-inch AMG wheels and sport body styling – more aggressive front and rear fascias – the GLA is a stylish piece. We might even call it cute. Considering our 4Matic model's reasonable $34,225 starting price, the interior treatment is both attractive and uses mostly quality finishes. The matte Satin Light Brown Poplar wood ($325) covers a large portion of the dash, while the real metal found on the air conditioning vents is elegant and handsome. There is a lot of plastic in the cabin: It's soft on the dash, and switches to a piano-black finish in spots, but the center console and door finishers don't feel like they came from the Mercedes parts bin. In general, the GLA's cabin feels roughly equal to that of the Audi Q3 and BMW X1 – nice, but a step lower than what we've come to expect from Mercedes. The two-piece, leather-lined seats look great, but even with standard 14-way adjustability, they lack support. The bottom cushion is very flat, and doesn't support the legs. For this author, that's a recipe for near-constant back pain. That said, the chairs do look good, especially in the brown of this test car. The GLA250, like a few other models in the Mercedes range, uses a 2.0-liter, turbocharged four-cylinder, delivering a weak 208 horsepower. It makes up for that shortcoming with 258 pound-feet of torque from 1,250 rpm to 4,000 rpm. On paper, this sounds good, but in the real world, the 2.0T's power is tough to access. That's due more to the shortcomings of the seven-speed dual-clutch automatic than the engine itself. With three modes – Eco, Sport, and Manual – we thought we'd find at least one that could serve up precise downshifts.
