GM recalls trucks and SUVs for brake pedal problem

The Basics: General Motors will recall over 473,000 North American examples of the 2015-2016 Chevrolet Silverado HD, GMC Sierra HD, and police pursuit versions of the Chevy Tahoe. These include 426,573 vehicles in the US and 46,837 in Canada, according to Reuters. The Problem: The brake pivot nut can loosen over time, which can render the pedal inoperative. This would be a danger to drivers trying to stop the vehicles. In some cases, the "Service Engine Soon" light might come on. Injuries/Deaths: None reported. The Fix: Dealers will inspect the pivot bolt, and if necessary they will apply adhesive to it and reinstall the part with increased torque. If You Own One: "We expect to start customer notifications shortly," GM spokesperson Tom Wilkinson told Autoblog.

If the brake pedal becomes loose or inoperative, it could interfere with the accelerator pedal, and/or the driver may be unable to safely stop the vehicle through application of the brake pedal, potentially affecting stopping distances and increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the pivot bolt installation to determine whether the vehicle has already received the production remedy. If not, the dealer will add adhesive to the nut, and reinstall the nut at an increased torque. Note: This condition may result in the "Service Engine Soon" light illuminating, and brake lights may stay on longer than expected.

Big And Boxy Might Be Best
As immense fans of the Back to the Future trilogy, we sometimes like to envision an alternate timeline in which General Motors had killed off GMC and kept Pontiac instead. The G8 GXP would still be on the road handily beating German sport sedans costing twice as much, while the lowly G3 would morph into a true subcompact-killer based on what is now the Chevrolet Sonic RS. While we're at it, let's go ahead and imagine the G6 has become the best-selling car in the US and the Torrent crossover is selling 20,000+ units per month. Far-fetched, we know.
The thing is, these fanciful statements would have to be true to make the case against keeping GMC. Pontiac may have offered more excitement than GMC, but money talks, and a full line of trucks, crossovers and SUVs have made a lot more money for GM than the arrowhead brand ever did. How much? As we learned last month, about two-thirds of GM's global profits came from its fullsize trucks, and GMC's trucks typically have thicker margins than their Chevrolet counterparts.

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!"
