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!"

EV cost burden pushing automakers to their limits, says Stellantis' CEO Tavares

DETROIT — Stellantis CEO Carlos Tavares said external pressure on automakers to quickly shift to electric vehicles potentially threatens jobs and vehicle quality as producers struggle with EVs' higher costs. Governments and investors want car manufacturers to speed up the transition to electric vehicles, but the costs are "beyond the limits" of what the auto industry can sustain, Tavares said in an interview at the Reuters Next conference released Wednesday. "What has been decided is to impose on the automotive industry electrification that brings 50% additional costs against a conventional vehicle," he said. "There is no way we can transfer 50% of additional costs to the final consumer because most parts of the middle class will not be able to pay." Automakers could charge higher prices and sell fewer cars, or accept lower profit margins, Tavares said. Those paths both lead to cutbacks. Union leaders in Europe and North America have warned tens of thousands of jobs could be lost. Automakers need time for testing and ensuring that new technology will work, Tavares said. Pushing to speed that process up "is just going to be counter productive. It will lead to quality problems. It will lead to all sorts of problems," he said. Tavares said Stellantis is aiming to avoid cuts by boosting productivity at a pace far faster than industry norm. "Over the next five years we have to digest 10% productivity a year ... in an industry which is used to delivering 2 to 3% productivity" improvement, he said. "The future will tell us who is going to be able to digest this, and who will fail," Tavares said. "We are putting the industry on the limits." Electric vehicle costs are expected to fall, and analysts project that battery electric vehicles and combustion vehicles could reach cost parity during the second half of this decade. Like other automakers that earn profits from combustion vehicles, Stellantis is under pressure from both establishment automakers such as GM, Ford, VW and Hyundai, as well as start-ups such as Tesla and Rivian. The latter electric vehicle companies are far smaller in terms of vehicle sales and employment. But investors have given Tesla and Rivian higher market valuations than the owner of the highly profitable Jeep and Ram brands. That investor pressure is compounded by government policies aimed at cutting greenhouse gas emissions. The European Union, California and other jurisdictions have set goals to end sales of combustion vehicles by 2035.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
