Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.

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.
