GM Design shows another early Hummer EV sketch

Like a new mother who's still so excited about her one-year-old baby that she can't stop showing ultrasound photos, General Motors is so excited about its biggest new baby, the battery-electric GMC Hummer, that it can't stop showing off development design sketches. The off-road monster with the 200-kWh Ultium battery pack debuted online on October 21 last year. The next day, the GM Design Instagram page posted some of the Hummer's early "theme sketches" leading to the production version. These had a conceptual flair to them, but were rather restrained. A month later, GM uncovered a series of development renderings showing off a much wilder truck bursting with more angles than a geometry text book. The archives have opened up again with a new "ideation sketch," this one between the first believable sketches and the second truck that Master Chief and Doomguy share on their days off.  All three sets of drawings show similar three-box proportions, it's the details that got a ton of love. On this newest sketch, the fenders flare a touch more than on the production truck, but the wheel wells are cut with the kind of clearance found on a Baja 1000 Trophy Truck. Out back, save for the tow hooks, the rear end is totally different than production. The sketch puts illuminated Hummer script across a narrow tailgate flanked by small square, taillights housing six individual elements. Beneath that, a bumper-less rear end puts nothing more than a sloped bash pate between the truck and the rocks it's just scrambled over. To our eyes, this is the best blend of production-ready comfort from the first sketches and zoot suit angles from the second that we've seen so far.  First deliveries of the GMC Hummer EV Edition 1 are expected before the year is out. When we get a chance to absorb the truck in its native habitats, we'll know whether there's cause for disappointment at what could have been. If so, with all this hunger among the monied for something different, we feel like restomodders have been given the perfect head starts on custom rebodied Hummers that would make things right.

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

2015 Chevy Silverado, GMC Sierra can tow up to 12,000 pounds

Think back to the launch of the 2014 Chevrolet Silverado. At the time, General Motors happily trumpeted that its fullsize pickup could tow up to 11,500 pounds when properly equipped - impressive stuff, no doubt. But now, revised tow rating practices have been put into place, called SAE J2807. And with these new methods of testing, GM can now officially rate both the Silverado and its GMC Sierra twin as being able to tow up to 12,000 pounds.
Of course, not all Silverado and Sierra models are capable of this feat. In fact, because of SAE J2807, most of the truck models have actually had decreases in tow ratings from the 2014 to 2015 model year. For example, a 2014 Silverado Crew Cab with the 5.3-liter V8, 5.7-foot box and 3.73 rear axle was rated at 11,200 pounds in 2014, but has since been reduced to 10,800 in 2015. Same goes for the Sierra.
But for 2015, both the Silverado and Sierra can be had with a more powerful 6.2-liter V8, as well as a Max Trailering Package that includes a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning, improved cooling and a new trailer brake controller. There are also four- and seven-pin, bumper-mounted connectors, a trailer hitch (duh), and a G80 locking rear differential. This configuration, with either model, is the only way you can actually tow 12,000 pounds.
