Chrysler recalls AWD 300, Charger, Ram 1500 over ZF transmission

What do the Chrysler 300, Dodge Charger and Ram 1500 all have in common? Yes, they're all Chrysler products, and two of them are based on the same platform. And we're sure you could find more similarities between them all, but the common trait we're looking at here is that, while they all come standard in rear-drive form, they're also available with all-wheel drive. And it's the transmission in those models that's the subject of the latest recall notice issued by the National Highway Traffic Safety Administration.
The output shaft on the eight-speed automatic transmission supplied by ZF to Chrysler for the AWD versions of the 300, Charger and Ram 1500 is apparently prone to fracture. That in the end could leave the vehicle without power and could, according to the NHTSA investigation, increase the chance of a crash. The vehicle could also roll away if even if left in Park without the handbrake applied.
That's why Chrysler is calling in 4,194 examples of those three models from the 2013 model year. Dealers will be responsible for inspecting the transmissions and, where necessary, replace the entire unit. See the full recall notice below for all the details.

Stellantis reports surprising 2020 results, is 'off to a flying start'

MILAN — Low global car inventories and cost cuts should boost Stellantis's profit margins this year, though a shortage of semiconductors and investments in electric vehicles could weigh on results, the newly-formed automaker said on Wednesday. The forecast came as Stellantis, created by the January merger of Peugeot-maker PSA and Fiat Chrysler (FCA), reported better-than-expected results for 2020 that sent its shares up around 3% in morning trading. "Stellantis gets off to a flying start and is fully focused on achieving the full promised synergies (from the merger)," Chief Executive Carlos Tavares said in a statement. Stellantis is the world's fourth largest carmaker, with 14 brands including Fiat, Peugeot, Opel, Jeep, Ram and Maserati. It said 2021 results should be helped by three new high-margin Jeep vehicles in North America and a strong pricing environment there. The U.S. market has driven profits for years at FCA and starts off as the strongest part of Stellantis. The group's guidance assumes no more significant lockdowns caused by the global COVID-19 pandemic, which shuttered auto plants around the world last spring. Stellantis should also get a lift as its starts to implement a plan aimed at delivering over 5 billion euros a year in savings, without closing any plants. Tavares has also pledged not to cut jobs. But a pandemic-related global shortage of semiconductors, used for everything from maximizing engine fuel economy to driver-assistance features, could hurt business. Auto industry executives have said the shortage should ease by the second half of 2021. Stellantis said its "electrification offensive" could also weigh on results this year. Automakers are racing to develop electric vehicles to meet tighter CO2 emissions targets in Europe and this week Volvo joined a growing number of carmakers aiming for a fully-electric line-up by 2030. Stellantis plans to have fully-electric or hybrid versions of all of its vehicles available in Europe by 2025, broadly in line with plans at top rivals such as Volkswagen and Renault-Nissan, although Stellantis has further to go to meet that goal. The carmaker is targeting an adjusted operating profit margin of 5.5%-7.5% this year. That compares with a 5.3% aggregated margin last year: 4.3% at FCA and 7.1% at PSA excluding a controlling stake in parts maker Faurecia, which is set to be spun-off from Stellantis shortly.

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!"
