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!"

The Army goes off-roading with a hydrogen Chevy Colorado

The Chevrolet Colorado is joining the service. General Motors is working with the US Army Tank Automotive Research, Development & Engineering Center (TARDEC) to build a Colorado powered by a commercial hydrogen fuel cell stack, and the Army will use it in "extremes of daily military use for 12 months." TARDEC is the department that tests "advanced military automotive technology" and integrates them into ground systems. The aim is to see how well the benefits of a fuel cell vehicle can be adapted to the battlefield; hydrogen-powered vehicles are quiet, torquey, produce water, and can be used to provide electricity in the field. GM says the design sketch above "foreshadows" the Colorado that will go to boot camp and beyond, making it clear that this won't be the average midsize pickup. The press release below has more.

"Hydrogen fuel cell technology is important to GM's advanced propulsion portfolio, and this enables us to put our technology to the test in a vehicle that will face punishing military duty cycles," said Charlie Freese, executive director of GM's Global Fuel Cell Engineering activities. Fuel cell propulsion has very high low-end torque capability useful in off-road environments. It also offers exportable electric power and quiet operation, attractive characteristics to both commercial and military use. "The potential capabilities hydrogen fuel cell vehicles can bring to the Warfighter are extraordinary, and our engineers and scientists are excited about the opportunity to exercise the limits of this demonstrator," said TARDEC Director Paul Rogers. "FCVs are very quiet vehicles, which scouts, special operators and other specialties place a premium," he said. "What's more, fuel cells generate water as a by-product, something extremely valuable in austere environments." GM and TARDEC have fuel cell development and research facilities located 20 minutes apart in Pontiac and Warren, Mich.

GM's Ultium EV platform finally shows up in Q3 sales numbers

General Motors has heralded its Ultium battery-electric platform as the future of its passenger car and truck lineup, but for the first two years of its existence, its impact on the marketplace has been virtually nonexistent. Well, that finally changed in the third quarter of 2023, and while the cars based on this architecture don't represent anywhere near the volume of GM's broader combustion portfolio, we're reaching a point where Ultium products are finally in view (and in the hands) of real-world shoppers. At this point, five U.S.-market Ultium models are in production: the GMC Hummer EV, Cadillac Lyriq, Chevrolet Blazer & Silverado EV, and BrightDrop Zevo 600. If you're not familiar with that last one, that's OK; it's a commercial product that you likely won't see on the road for some time. Together, these four combined for 4,257 sales in the third quarter alone — up from 2,663 for the entire first half of the year. While that may not seem like a significant uptick when viewed from altitude, the quarter-to-quarter numbers paint a clearer picture.  Let's toss out the stragglers first. The Chevy Blazer EV, and Silverado EV for example, are barely in production. GM delivered 19 Blazers and 18 Silverados in the third quarter and that's the entirety of their production runs so far. Likewise, GM's BrightDrop Zevo 600 delivery van effectively exists apart from the consumer marketplace, so its contribution of just 35 units can be set aside too. That leaves us the two you've heard of: the GMC Hummer EV and Cadillac Lyriq — models with high sticker prices and long reservation queues.  Through the second quarter (remember, we're talking six months here), GMC sold 49 Hummer EVs. No typo. In the three months that made up the third quarter, GM moved 1,167 of them. Not only is that a dramatic improvement over the first half, but it's more Hummers than GMC sold in the entirety of 2022 (854). Lyriq's improvement was less eye-popping on paper, but after moving just 122 total units in 2022 and 2,013 of them in the first half of 2023, Cadillac managed to up that figure to 3,018 units in the third quarter alone.  GM is betting its short-term EV future on the Ultium platform, so these trends need to continue if that's going to be a profitable wager.
