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!"

2018 GMC Terrain loses the V6 and gains a diesel for an all-turbo lineup

You may have noticed that compact crossovers are kind of a big deal these days. After eight years on sale, GMC is finally getting a new version of its littlest ute, the Terrain, for 2018. And it can't arrive a moment too soon. The 2018 GMC Terrain made its debut tonight on the eve of the 2017 Detroit Auto Show. The 2018 Terrain looks to be completely new, and is now built on GM's D2XX platform. It again shares a platform and major components with the Chevrolet Equinox; like the 2018 Equinox, the Terrain will offer three engines, including two turbocharged gas four-cylinders and a turbodiesel four. The base 1.5-liter gas four makes 170 horsepower and 203 pound-feet of torque, while the 2.0-liter inline-four puts out 252 hp and 262 lb-ft. (The 2.0 basically takes the place of the 3.6-liter V6 offered in the outgoing Terrain.) GM's 1.6-liter diesel four will also be available, making 137 hp and 240 lb-ft of torque in this application. Both gas engines will be paired with nine-speed automatic transmissions, while the diesel gets a six-speed auto. No fuel-economy claims have been made, but we expect the new models to outdo the current versions, with the diesel reaching around 40 mpg on the EPA highway cycle. View 14 Photos The new Terrain's design is equally fresh and does a good job of differentiating it from the related Equinox, with details very reminiscent of the new GMC Acadia. The lighting elements are even more intricate here, with LEDs used for the daytime running lights and taillamps. GMC designers gave it the floating-roof look, which is successful aside from the odd placement of a trim badge at the base of the D-pillar. Terrains will again be available in SL, SLE, SLT, and range-topping Denali trim, with the latter featuring the signature satin chrome grille, chrome accents, and monochrome paint scheme GMC uses on all of its top-trim models. The interior sees an upgrade in materials and a more-thoughtful layout, with a new version of GM's Electronic Precision Shift gear selector using buttons and switches instead of a lever to open up more space on the center console. Both front- and all-wheel-drive models get a Traction Select system that will tune the shift points and throttle points for specific driving conditions via a knob at the rear of the console. On models equipped with all-wheel drive, a front-drive mode disconnects the rear axle to improve fuel economy.

Watch the 2022 GMC Hummer EV launch using its Watts to Freedom mode

It’s nearly the July Fourth weekend, and GM is celebrating Independence Day a little earlier than most. The celebration comes in the form of a GMC Hummer EV demonstrating Watts to Freedom, or WTF, mode for us on video. You can watch it at the top of this post, but the idea is rather simple. ItÂ’s just a video of a Hummer development vehicle accelerating as quickly as it can from 0-60 mph and beyond. GMC claims its 1,000-horsepower electric Hummer is capable of hitting the 0-60 mph mark in “approximately 3 seconds,” which is borderline terrifying for how large of a vehicle it is. The super-quick time is possible when using the Watts to Freedom launch control mode, which “channels the propulsion systemÂ’s tremendous power into acceleration bursts.” The truck will still be plenty fast when accelerating normally, but WTF mode is what you should use to unlock its full potential. GMCÂ’s video shows us the graphics it uses in the digital cluster to signal Watts to Freedom is activated, and the whole sequence looks like it leans on U.S. military themes for both design and phrasing. For example, GMC lets you know that Watts to Freedom is ready via an “Armed” message in the cluster.  The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos Instead of a rumbling exhaust and screeching tires, the Hummer appears to silently launch with all four tires grabbing on and catapulting the truck away. It looks quick as it throws all of the weight rearward into an accelerative squat. And in case you missed it, thatÂ’s a lot of weight — GMC says itÂ’ll tip the scale at 9,046 pounds. GMC has previously said that production will begin in late 2021, and this video continues to confirm that timeframe with a note saying “initial availability Fall 2021.” Do keep in mind that only the sold-out Launch Edition is coming at that time. Other cheaper variants will follow in the years to come. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
