GMC Hummer EV coming to Extreme E with Chip Ganassi Racing

The electric off-road racing series Extreme E is getting another famous face. This time it's not a person, but rather a vehicle: the GMC Hummer EV. GMC announced that it will be the main sponsor for the Chip Ganassi Racing Extreme E team. With the sponsorship, GMC gets to tweak the Extreme E Odyssey 21 race SUV to look more like the Hummer EV pickup and SUV that starts production late this year. The changes are subtle but effective, with the nose getting a full-width light-bar motif. Of course the race SUV is vastly more rounded than the road-going truck. It also features a standardized chassis from Spark Racing and a battery pack from Williams. The team is able to provide its own electric motor, though, which the series limits to 550 horsepower. The GMC Hummer EV race SUV will make its competition debut alongside several other pedigree teams at the first Extreme E event in Saudi Arabia this April. Three teams are operated by Formula One drivers including Sir Lewis Hamilton, Nico Rosberg and Jenson Button, the latter of whom will be driving. Andretti United will also field a team, a familiar competitor to Chip Ganassi in other racing series such as IndyCar. As for drivers, two World Rally Championship champions will compete: Carlos Sainz and nine-time consecutive champion Sebastien Loeb. The series will feature five races and with the way the competition is shaping up, they should be very interesting to watch. Related video:

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 Sierra 1500 AT4X: Can you sleep in it?

Autoblog may receive a share from purchases made via links on this page. Pricing and availability are subject to change. The recently introduced GMC Sierra AT4X is an impressive combination of off-roading and luxury. But can you sleep in it? Pickups are great for towing campers or as a platform upon which to build out overlanding rigs, but from the factory they usually aren’t as useful as SUVs to sleep in, considering half of the length of the vehicle is taken up by the bed. Let's see how the AT4X fares. Space The biggest thing to consider when it comes to camping in your car is whether or not there is enough space in it for you and possibly a partner to lay down comfortably. This is tough when it comes to pickup trucks, which are hampered by the fact that half (or more) of the length of the vehicle is taken up by the bed of the truck. Some trucks have added features like lie-flat seats that make sleeping in them a bit easier, though itÂ’s still not a perfect solution. Unfortunately the AT4X is not one of those trucks. While the seats do lay back quite a good amount, I wasnÂ’t able to get comfortable enough to rely on them for a good nightÂ’s rest. To the rear we go. If youÂ’re vertically challenged, you may be in luck, especially if you donÂ’t sleep stretched out. The Sierra 1500 is a wide truck, almost 7 feet wide in fact. The rear bench measures 56 inches in width, which isnÂ’t a great option for most adults unless you really like sleeping in the fetal position. ItÂ’ll do in a pinch but I wouldnÂ’t expect to get a great night's sleep again and again.  Below the bench, which folds up and out of the way, is a relatively flat floor which can offer a bit more length. At 63” it still isnÂ’t enough for me to lie down with the doors closed, but it is much less cramped than spending the night on the bench. The subtle bump in the middle of the floor, which is much less severe than the ridges in the bed, can easily be remedied by an inflatable sleeping pad like the Sea to Summit Ether Light XT, or, even better, a cheap air mattress from Walmart. The Bed The bed of the AT4X seems like the most logical place to sleep. After all, it is named the bed for a reason right? If you have an inflatable mattress, then sure, but due to the ridges on the floor, a simple sleeping pad and sleeping bag will not be enough here. Additionally, the length of the bed leaves something to be desired.
