2014 GMC Sierra 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year.

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!"

GMC offers more 2024 Hummer EV SUV details, photos

GMC has shared more details about its 2024 Hummer EV SUV after its debut during the NCAA Final Four tournament. The SUV which follows the Hummer EV pickup, is smaller, more maneuverable and has a few features the truck doesn’t. GM says itÂ’s meant to strike a balance between off-road capability and on-road driving. GM also says Edition 1 reservations are already sold out. Compared to the truck, the Hummer SUV has a wheelbase about 9 inches shorter. With four-wheel steering, its turning circle is just 35.4 feet, which GM emphasizes is tighter than that of the Ford Mustang Mach-E (38.1 feet). ItÂ’s also less than the Hummer pickupÂ’s 37.1-foot turning circle. The SUV, which, at 196.8 inches long, is 20 inches shorter than the truck overall. It also features a much shorter rear overhang, at 35.5 inches. While thatÂ’s all helpful maneuvering through city traffic or suburban parking lots, it also provides advantages off-road. It has an approach angle of 49.6 degrees, a 49.0-degree departure angle and a 34.4-degree breakover angle. Suspension travel is 13 inches front and rear, with 16 inches of maximum ground clearance thanks to its Extract Mode that temporarily raises the vehicle to get out of tricky terrain. It can ford water 32 inches deep. It also features the same CrabWalk mode as the pickup. Available Ultravision provides 17 cameras, including underbody views to help navigate the trail. The Hummer SUV benefits from an enclosed cargo area behind the second row of seats. It still features the Infinity Roof with removable panels above the two seating rows to essentially turn the SUV into a convertible. At the rear is a swing-out tailgate that opens wider than the width of the vehicle. A spare tire rides on the tailgate as well. With the rear seats folded, cargo volume peaks at 81.8 cubic feet.  Additional hidden storage space is found below the recycled rubber floor mat, which features a design inspired by the moonÂ’s Sea of Tranquility (that's where Apollo 11 landed). As for technology, the Hummer SUV gets a 13.4-inch infotainment screen, plus a 12.3-inch instrument display in front of the driver. Fourteen cameras come standard, and the aforementioned Ultravision provides a total of 17 cameras, including a surround view. The MyGMC mobile app offers satellite rendered trail maps that can also help manage energy consumption off-road and make sure you have enough juice to make it to a charger when finished.
