2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:      

There's an impending shortage of new trucks in America's heartland

URBANDALE, Iowa — Jerry Bill is worried the novel coronavirus could hurt business at the Des Moines auto dealership he runs, but not because of a shortage of buyers for the big Ram pickups on his lot. "Our biggest issue will be if we don't get more inventory," said Bill, general sales manager of Stew Hansen Chrysler Dodge Jeep Ram, which sells around 2,700 new vehicles a year in Urbandale, a suburb of Iowa's capital Des Moines. After a drop in sales in April when consumers stayed home, Bill expects pickup truck sales to end May similar to where they were a year earlier. And if demand remains strong, Bill said he will run out of popular models in June. Fiat Chrysler began slowly restarting Ram truck assembly lines on Monday after a two-month shutdown. The U.S. economy contracted in the first quarter at its sharpest pace since the Great Recession of 2007-2009 because of lockdown measures aimed at slowing the spread of the coronavirus. Economists warn the second quarter will be much worse. Still, far from the lockdowns of states like New York, Michigan or Ohio, dealerships like Stew Hansen have provided FCA and Detroit rivals General Motors and Ford a rare bright spot: strong sales of pickup trucks in America's heartland. Overall U.S. sales of cars and light trucks crashed to the weakest pace in 50 years last month. But sales of big Detroit brand pickups, particularly in southern and western states less affected by the outbreak, significantly outperformed the market, industry executives and analysts said. Pickup trucks are one of the most profitable automotive segments in the world. They account for a huge portion of the Detroit automakers' profits and formed a huge lure for Peugeot, which expects to merge with FCA by early 2021. The pressure is now on to boost pickup truck production and send vehicles to dealers in parts of the country with dwindling supplies. That is particularly true for GM, which is running short of certain truck models after losing 40 days of production to a strike last fall. "If you don't have what someone wants, they can choose to go to another brand," said Cox Automotive analyst Michelle Krebs. 'Easiest swap ever' Detroit automakers in March rolled out large discounts — such as interest-free loans for seven years — to keep vehicles rolling off dealer lots.

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!"
