GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

2023 J.D. Power APEAL Study shows new-car customer satisfaction scores slip

J.D. Power survey results have been slightly up but mostly down for automakers this year, literally. In February, the 2023 Vehicle Dependability Study showed an overall decline compared the 2022 a month before the Customer Service Index Study did the same. The trend reversed in June with a better overall score on the 2023 U.S. Electric Vehicle Consideration Study than in 2022, then declined again the same month on with a lower overall score on the 2023 Initial Quality Study. The declines continue with the 2023 J.D. Power U.S. Automotive Performance, Execution and Layout (APEAL) Study, overall satisfaction among the 84,555 respondents down two points overall compared to 2022, to 845 out of 1,000 points. Because last year's score dropped compared to 2021, this year marks the first consecutive decline in the study's 28-year history. The study tries to "[measure] owners' emotional attachment and level of excitement with new vehicle" after 90 days of ownership by asking new owners to rate 37 attributes in 10 areas around the vehicle, such as the feeling they get when they hit the accelerator. Satisfaction with nine of the attributes is down this year versus last, fuel economy the only segment to show better results with 15 points more satisfaction. Styling and infotainment are big drags on satisfaction. Responses to new car exterior looks tallied 888 points, down from 894 last year, the largest drop in this year's study. On the digital side, less than half of those surveyed this year said they prefer using a manufacturer's built-in infotainment. From 70% of respondents in 2020 preferring to use a manufacturer's in-house software to play audio instead of Android Auto or Apple CarPlay, that's 56% in 2023. Going all-in on Google appears to have the best effect. J.D. Power said that vehicles with both Google's Android Automotive Operating System (AAOS) and Google Automotive Services (GAS) "score higher in the infotainment category than those with no AAOS whatsoever. AAOS without GAS receives the lowest scores for infotainment of the three categories."  Frank Hanley, senior director of auto benchmarking at J.D. Power, said, "Despite the technology and design innovations that manufacturers put into new vehicles, owners are lukewarm about them. While innovations like charging pads, vehicle apps and advanced audio features should enhance an owner’s experience, this is not the case when problems are experienced.
