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.

2015 Chevrolet Corvette Z06 [w/videos]

I think I was supposed to be back hours ago. Driving northwest on State Road 190 with a final destination deep in the heart of the Death Valley National Park, it occurs to me that I might have agreed to return after an hour or so, instead of the four I'll end up stealing, solo, in the new Z06. Somewhere in the combination of mountain vistas, arching, speed-hungry desert roads, and the sound of this titanic engine on a constant run up the rev ladder, I forgot everything I'd promised back at home base. The generous, civilized part of me worries for a moment that absconding with the new-best Corvette might have left one of my fellow journalists without a car. But the selfish part of me – the part largely in control of the rocket-launcher of a throttle under my right foot ­– says "screw it." I spent two days with the 2015 Chevy Corvette Z06, a monster of a sports car that will soon be dominating track days everywhere, and I never once was inclined to share it. Hurtling through the shattered stillness of the desert and pulling big Gs at Spring Mountain circuit, I never felt overly disposed to give up my seat. This Corvette, more than any I've yet driven, was deep enough to hold my attention; for two days, for two years, probably. With this Z06, the Corvette steps over the amazing-for-the-price category, and solidly into the best-cars-in-the-world zone. There are peripheral elements that remind me of its blue collar, Bowtie heritage, sure, but there's more that simply begs me to carry on driving... faster. Most casual car observers will be able to pick the 2015 Z06 out from its less aggressive Stingray brothers. Subtler hints include a new, more open grille, larger extractor on the taller hood and rather discreet badges on the flanks of the car. More outrageous is the finned spoiler on the rear trunk lid, and the widebody look offered from flared fenders – an extra 1.57 inches (40 millimeters) at their beefiest point. Even driving around performance-car-laden Pahrump, NV – loaded thanks to the very active community at the Spring Mountain racing resort – members of the local populace were turning heads, waving and generally noting the Z06 with approval when I drove through town. In Torch Red over black painted aluminum wheels, staggered at 19-inches in front and 20 at the back, the amped-up Z06 hits a new level of road presence for the C7.

Race Recap: Rolex 24 at Daytona was fast and feisty

Let the record show that victory at the 2015 Rolex 24 at Daytona went to the No. 02 Chip Ganassi Racing with Felix Sabates Target/Ford EcoBoost Riley DP driven by Verizon IndyCar drivers Scott Dixon and Tony Kanaan and NASCAR drivers Jamie McMurray and Kyle Larson. The winner did 740 laps to cover 2,634.3 miles in 24 hours and 57.667 seconds. That's a statement to this year's pace in spite of 18 cautions, two more than last year: the Michael Shank Racing Ligier got pole with a time of 1:39.194, slower than last year's pole time of 1:38.270; however, the winning car last year only did 695 laps. The fight for top honors was shaved to a four-car battle over the first third of the event. The No. 02 Ganassi car took the lead on the first lap, swapping it well into the night with the No. 01 Ganassi car, the No. 10 Wayne Taylor Racing Corvette DP, and the defending champion No. 5 Action Express Corvette DP, all of them staying within about 20 seconds of one another. The Action Express car had a fuel connector come loose and lost three laps getting towed back to the pits to have it reattached, but was back in the lead 18 hours in. The No. 01 Ganassi car dropped out with recurring clutch problems 22 hours in, retiring not long after. A race-within-the-race is where the concluding action happened, a seven minute, 30-second dash from the end of the last caution to the checkered flag. During the penultimate pit stops with an hour to go, Dixon was in second place followed Jordan Taylor in the Wayne Taylor Racing DP into the pits but beat him out, taking the lead. The Action Express car was in third. In the last pit stops of the race, Dixon gained even more time, getting a four-second advantage over Taylor. Then a full-course caution came out twenty minutes before the finish when a Prototype Challenge car hit the wall and caught fire, bunching up the field. That closed the pits, but the Wayne Taylor Racing car had to pit during that yellow because of a miscalculation of driver time. No driver can be behind the wheel for more than four hours in a six-hour period but Jordan Taylor was going to go over, so he came in to swap out for brother Ricky. That cost the team any chance of second place, since they took an additional drive-through penalty for entering closed pits. When the track went green again, Sebastien Bourdais in the Action Express car stayed all over Dixon for the final five laps but couldn't get around him.
