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.

Battery Show 2015: Genovation GXE Corvette EV designed for the 'Ring

The Genovation GXE all-electric Corvette has broken cover. At the Battery Show 2015 in Novi, MI, this week, the converted C6 Z06 Corvette that we first heard about back in August was tucked into a booth along the back wall. Don't let the demure location fool you. This is a muscle-y electric vehicle, ready to roar into the limited-run, expensive EV game. The Genovation GXE Corvette can go from 0-60 miles per hour in three seconds and has a top speed of 200 mph. The powertrain was designed and built in the US, and offers over 700 horsepower and over 600 pound-feet or torque. With a near 50/50 weight distribution, this is "a real driver's car," Genovation CEO Andrew Saul told AutoblogGreen. Saul said that the GXE was designed to do two hard laps at Nurburgring thanks to a 44-kWh battery pack uses the same sort of cylindrical 18650 cells that you can find in a Tesla. That translates to about 40-50 miles of fast, on-road driving, Saul said, or 150 miles on the New York City test cycle. That particular test, "simulates low speed urban driving with frequent stops," according to DieselNet. The car also has a 6-kW charger and a six-speed manual transmission and the adjustable regenerative braking levels can be controlled by paddles on the steering wheel. Of course, none of those performance figures have been proven yet because the GXE hasn't had a chance to hit the road. Saul said that it will take another three-to-four weeks to finish the build and then, finally, there will be a few weeks of road testing. This will include a quarter-mile run on a track as well as a trip to Nevada to do a several-mile top speed test. If all of that sounds like something you're interested in, then get ready to open your wallet wide and wait. Saul said that buying one will set you back $330,000 (just $290,000 if you bring your own C6 Z06). Genovation also won't be making all that many. Saul said he expects to put the GXE into limited production of under 200 units, starting off at maybe five or 10 a year.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
