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!"

2022 Hummer EV Edition 1 pickups ready to go to customers

It's official: Two years after GM announced the electric GMC Hummer pickup, the first couple dozen units have left the line at the GM Factory Zero Detroit-Hamtramck Assembly Center, according to GM president Mark Reuss. In an interview with CNBC to celebrate the milestone, Reuss said 17 Hummer EVs are ready for delivery to customers. This makes the Hummer the first of GM's new Ultium-based EVs to leave the factory, and the second electric pickup on the market after the Rivian R1T. The first 1,200 Hummer EVs made will be Edition 1 models, all of which are Interstellar White outside with Lunar Horizon interiors and bronze badging. Each of the $112,595 pickups is powered by three Ultium motors producing a GM-estimated 1,000 horsepower and 11,500 pound-feet of torque, loaded with features like height-adjusting adaptive suspension, skid rails and rock sliders, 35-inch tires, the diagonal-driving CrabWalk, the launch control system Watts to Freedom that unlocks a three-second sprint to 60 miles per hour, and Super Cruise. Range is a GM-estimated 329 miles when the 200-kWh battery is fully charged. As these filter out to eager owners, GM is prepping the next four phases of the Hummer rollout. About a year from now, in autumn of 2022, Factory Zero will begin production of the first widely available Hummer, the EV3X pickup that starts at $99,995 before destination. Three Ultium motors will provide an estimated 800 horsepower and 9,500 pound-feet of torque to a range estimated beyond 300 miles. Spring of 2023 is expected to deliver the Hummer EV2X pickup at an MSRP of $89,995, utilizing two motors producing a total 625 hp and 7,400 lb-ft over a range also estimated to go beyond 300 miles. Around the same time, the first units of the $105,595 Hummer SUV Edition 1 are planned to head down lines at Factory Zero. Finally, in the spring of 2024, the entry-level $79,995 Hummer EV2 pickup and its two-motor powertrain should arrive, making the same output as the EV2X, but only good for a range of around 250 miles. That won't be all we see from Factory Zero, either. GM invested $2.2 billion in the Detroit-Hamtramck plant that once built bread-and-butter GM fare like the Chevrolet Impala, Buick LaCrosse, and Oldsmobile Toronado in order to turn the facility into its first EV base of manufacturing operations for Ultium products. The battery-electric Chevrolet Silverado and GMC Sierra pickups will be built there, as will the Cruise Origin robotaxi.

GMC's electric Hummer could someday serve alongside the Humvee in the U.S. Army

Every civilian Hummer model traces its roots to AM General's Humvee, which made its combat debut when the United States invaded Panama in 1989. Fast forward to the 2020s, and the tables have turned. The born-again Hummer that will arrive with an electric powertrain and a GMC emblem could spawn a military-spec truck. "[The upcoming Hummer] is a full-size truck with 400 miles of range and 1,000 pound-feet of torque, it's a very highly capable vehicle. That could provide a great base platform for an electric vehicle to be used in the military context," said David Albritton, the president of General Motors Defense, in an interview with GM Authority. Although he didn't sketch out the Hummer's role in a battalion, its range, torque, and dimensions would theoretically make it well-suited to carrying soldiers, weapons, and/or gear like radio equipment. It wouldn't necessarily look like the production model (shown above in a preview image). General Motors Defense might use its basic platform and its powertrain technology to build a purpose-designed off-roader, like it did with the Colorado Infantry Squad Vehicle (ISV) it will soon begin manufacturing for the Army. The ISV shares 90% of its parts with the regular-production Chevrolet Colorado, but the two vehicles look nothing alike. Securing a contract with the American military is easier said than done, and Army officials haven't publicly expressed an interest in sending the upcoming Hummer into a war zone. We'll learn more about what a battle-ready electric truck could look like after the showroom-bound model makes its debut. In the meantime, Humvee production continues, and AM General introduced a comprehensively updated model named NXT 360 in 2018. Related Video:     Green GMC Hummer Truck Electric Military
