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 Chevrolet Bolt is headed to China as a Buick SUV

When spy photos of what appeared to be Chevrolet Bolt EV with some minor front- and rear-end updates circulated last week, Autoblog surmised that GM was working on some sort of Bolt-based vehicle — potentially a crossover — to be sold in China as a Buick. We may just have corroboration for that theory. On Thursday, Motor1.com spotted a story published earlier this week on the Chinese site Auto Home which claims that GM has applied to sell an all-electric SUV under the Velite 7 nameplate in China.  There's little differentiating the Velite 7's exterior from the Bolt EV's, apart from bumpers, badges, and a little extra ground clearance. Up front, the bowtie is replaced by a round Buick badge, and the bumper picks up an almost Prius-like appearance thanks to contrasting vertical elements and a thin grille bleeding into the head lights to give it a full-width appearance. Chevy Bolt-based prototype View 16 Photos If the Chinese report is accurate, there is one significant difference under the skin. Per the application, the Buick crossover variant is to be powered by a 174-horsepower electric powertrain. That's down 26 horsepower from the Bolt EV's powertrain, and we can't help but think that a lifted Buick variant might just need every pony it can get.  The needs of the Chinese market are unique, and we're certain GM knows what it's doing if these figures are accurate. We have no reason to believe Buick plans to sell the Velite 7 EV here in the States, though we expect an updated Chevy Bolt eventually, and we wouldn't be surprised if Buick brings something along shortly to fill the void left by the departure of the Regal sedan and its variants.  Related Video:

Take a close look at the guts of the Chevy Volt battery, powertrain

Just how intimate would you like to get with the powertrain in a Chevy Volt? If you're anything like YouTube user d55guy, then spending a half hour filming yourself taking apart the battery pack, motor, inverter and more for a look inside sounds like your idea of fun. After all, this way you get to see the cooling system, the heavy safety kill switch and count up the individual cells in the battery modules. Fun! Turns out, we also enjoy languidly paced Volt dissection video goodness, and we think you might want to see it as well. So, we've embedded two videos below and if you don't have a better understanding of how the Volt is put together after watching them, well, at least you can't say we never tried to show you anything. Given that what's really happening here is the organized 'destruction' of an expensive and potentially dangerous object, let's talk safety. There's a serious disclaimer at the beginning of the videos and on the YouTube description page, but we feel the need to repeat the gist of it here: do not try this at home. The creator of the video says he is a trained engineer and has been doing things like this "for the better part of a decade," so he apparently knows what he's doing. With that in mind, watch it all below. When you're done seeing the insides of a Volt powertrain up close, if you need more filmed EV dissection/destruction, check out this video designed for first responders approaching a damaged Tesla Model S.
