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.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Porsche tops JD Power APEAL study for 12th time

JD Power's 2016 Automotive Performance, Execution, and Layout (APEAL) study hasn't changed much this time around with Porsche coming in at No.1 for the 12th consecutive year, while BMW was close behind in second. Jaguar and Mercedes-Benz tied for third with Land Rover, Lexus, and Lincoln tied for No.5. The APEAL Study, according to JD Power, measures owners' level of excitement and emotional attachment across 77 parameters. Brands and cars are rated on a 1,000-point scale. The study found that new cars with modern safety features including low speed collision avoidance and blind spot monitoring have higher APEAL scores than vehicles without the features. The overall industry score increased from 798 to 801, which JD Power claims was helped by the launch of a variety of new vehicles. This year, 22 out of 30 new or redesigned cars received a higher score than the vehicle's respective segment average. Porsche is once again at the top of the list as the automaker's score increased by three points to 877. BMW outscored Jaguar to take second place with a score of 859, while the British automaker dropped three points from last year with 852 points. Volkswagen overtook Mini to become the top-ranked non-premium brand with 809 points, while the latter automaker trailed behind by one point. At the end of the scale, Smart came in at the very bottom for the second year in a row with a score of 745 points, which represents an increase of 62 points over last year. Fiat's score increased by six points to 755, but still confined the automaker to second-to-worst place for a consecutive year. Mitsubishi's score increased to 770, up from 755, to become the fourth-worst brand, while Jeep fell to third-worst with a decrease in seven points to 756. General Motors received six segment-level awards, followed by Hyundai with five, and BMW and VW earning four apiece. Surprise segment victories include the Chevrolet Camaro, which outscored the Dodge Challenger, and the Lexus RC which ranked above the BMW 4 and 3 Series.
