Three automotive tech trends to watch in 2018 and beyond

Every year, technology plays a bigger and bigger role in the auto industry. To put things in perspective, 10 years ago iPod integration and Bluetooth were cutting-edge in-car innovations, and smartphones and apps weren't yet a thing since the first iPhone was only about six months old. And I can't recall anyone talking about autonomous cars. Compare that to today, with mainstream coverage of the auto industry dominated by autonomous technology, along with electrification and almost every move made by Tesla. These three topics were the most significant trends of car tech in 2017 and I believe they will continue to shape the auto industry in 2018 and beyond. Let's examine them. Full Autonomy Gets Closer to Reality While there were many developments this year that indicate we're inching closer to fully autonomous vehicles, I was behind the wheel for hours to witness one of them. In October I had the chance to test Cadillac Super Cruise on a 700-mile, 11-hour drive from Dallas to Santa Fe – and had my hands on the wheel for maybe 45 minutes max throughout the entire trip. Super Cruise is far from making the Cadillac CT6 or any GM vehicle fully autonomous, and has limitations such as functioning only on pre-mapped main highways. While it simply adds a layer of lane centering to adaptive cruise control, the technology will go a long way in making mainstream drivers more comfortable with letting machines take over. On a separate front, GM is pushing ahead with fully autonomous vehicles and announced last month that it plans to launch of fleets of self-driving robo-taxis in several urban areas in 2019. While most automakers are also in the race to make autonomous cars a reality, GM's turbocharging of its efforts appeared to be in response to Waymo, which announced just weeks earlier that its Early Rider Program in the Phoenix area would go completely driverless. The Early Rider Program launched last April, offering the public a chance to ride in Waymo's autonomous Chrysler Pacifica minivans. In this new phase of testing, Waymo is using its own employees as guinea pigs instead of the public while the vehicles operate without a human behind the wheel, and takes another giant step forward for fully autonomous driving.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

U.S. new-vehicle sales in 2018 rise slightly to 17.27 million [UPDATE]

DETROIT — Sales of new vehicles in the U.S. rose slightly in 2018, defying predictions and highlighting a strong economy. Automakers reported an increase of 0.3 percent over a year ago to 17.27 million vehicles. The increase came despite rising interest rates, a volatile stock market, and rising car and truck prices that pushed some buyers out of the new-vehicle market. Industry analysts and automakers said strong economic fundamentals pushed up sales and should keep them near historic highs in 2019. "Economic conditions in the U.S. are favorable and should continue to be supportive of vehicle sales at or around their current run rate," Ford Chief Economist Emily Kolinski Morris said after the company and other automakers announced their sales numbers Thursday. That auto sales remain near the 2016 record of 17.55 million is a testimonial to the strength of the economy, said Mark Zandi, chief economist at Moody's Analytics. The job market, he said, has created new employment, and wage growth has accelerated. "That's fundamental to selling anything," he said. "If there are lots of jobs and people are getting bigger paychecks, they will buy more." The unemployment rate is 3.7 percent, a 49-year low. The economy is thought to have grown close to 3 percent last year, its best performance in more than a decade. Consumers, the main driver of the economy, are spending freely. The Federal Reserve raised its key interest rate four times in 2018 but is only expected to raise it twice this year. Auto sales also were helped by low gasoline prices and rising home values, Zandi said. It all means that people are likely to keep buying new vehicles this year even as they grow more expensive. The Edmunds.com auto-pricing site estimates that the average new vehicle price hit a record $35,957 in December, about 2 percent higher than the previous year. It will be harder for automakers to keep the sales pace above 17 million because they have been enticing buyers for several years now with low-interest financing and other incentives, Zandi said. He predicts more deals in the coming year as job growth slows and credit tightens for higher-risk buyers. Edmunds, which provides content, including automotive tips and reviews, for distribution by The Associated Press, predicts that sales will drop this year to 16.9 million.
