2014 Chevy Silverado, GMC Sierra first pickups to ace updated NHTSA tests [w/video]

General Motors has just become the first pickup truck manufacturer to receive five-star overall vehicle scores in the National Highway Traffic Safety Administration's New Car Assessment Program. The updated safety standards, which went into effect in 2011, are more strenuous than the previous NHTSA curriculum and involve collecting both more and more substantial data, reflecting the improved safety inherent in newer vehicles. This feat is made more impressive by the fact that both Ford and Ram have released brand-new trucks since the new testing went into effect - GM's victory is no technicality.
The rating only applies to the redesigned, light-duty Silverado, Sierra and their upmarket variants, High Country and Denali, respectively, while only Crew Cab variants were tested. Considering that the four-door body style will make up 60 percent of GM's light-duty truck sales, the exclusion of the other variants seems reasonable.
This news is sure to be yet another feather in GM's pickup-oriented cap. Be sure to scroll down for video of the crash testing, as well as the full press release from General Motors.

2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.
