2018 GMC Sierra 1500 Buying Guide | What you need to know about this pickup truck

The GMC Sierra is a work-capable truck that can be optioned like a luxury car. Variety and choice are the keywords for the Sierra, not to mention close rivals like the Ford F-150, Ram 1500, and Chevrolet's own Silverado 1500. A Sierra buyer has a seemingly infinite list of choices when it comes to specifying exactly what they need in their pickup. In terms of cab length alone, there are three choices – Regular, Double, and Crew – to go along with your pick of Short, Standard, or Long cargo bed. Engines range from a 4.3-liter V6, upward to a range-topping 6.2-liter V8 available in top trim levels like the SLT and Denali. The Sierra can be ordered with a choice of two- or four-wheel drive, and transmissions include both a 6- and 8-speed automatic, depending on your choice of powertrain and trim. Changes for the 2018 model year include the standard fitment of a rearview camera, along with a Tire Fill Alert system that lets the driver know when the correct pressure has been reached. A 7.0-inch touch-screen stereo system is also now standard equipment on base Sierras. Is the 2018 GMC Sierra Safe? The National Highway Traffic Safety Administration gives the 2018 GMC Sierra 1500 an overall crash-test rating of five stars. In front and side impact tests, the latest Sierra 1500 scored a five-star safety rating. A four-star rating was recorded in the Rollover resistance test – this rating applies to Sierra trucks fitted with either rear- or all-wheel drive. Because the Sierra is such a popular vehicle, it's worth noting that the NHTSA conducted crash tests on models fitted with both these drivetrains, and in two cab lengths. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, also tested two versions of the Sierra 1500. The extended cab model registered "good" ratings in all but one of the IIHS' crash tests. Driver side protection in the small overlap test was deemed "acceptable" – front passenger-side results were not rated. Headlight effectiveness was given an "acceptable" rating, dependent on trim level selected. Meanwhile, the ease of use of the Child Seat Anchors (LATCH) was deemed "acceptable" in the extended cab Sierra. Ratings dip slightly for the Sierra 1500 in standard cab format. Driver-side protection in the front small overlap test drops to "marginal," while the available LATCH system scored a "poor" for its ease of use.

Autoweek dubs GMC Canyon, VW GTI its 2015 'Best of the Best'

For kids around the globe, tis the season for Santa, reindeer and presents. For the automotive industry, the last quarter of each year is reserved for awards, whether they come from Motor Trend, Car and Driver, Automobile, or yes, Autoblog. The latest to get released comes from our friends at Autoweek. The magazine has echoed other outlets, naming a Volkswagen hatchback and a small pickup from General Motors as its Best of the Best. Unlike Motor Trend, which handed out its golden calipers to the Chevrolet Colorado and Volkswagen Golf range, Autoweek doled out its awards to the Colorado's twin, the GMC Canyon, while singling out the hottest version of the Golf, the GTI. "This is the best hot-hatch on the American market – and it may be the best car you can buy for less than $30K," one AW staffer said in the publication's article on the feature. Other staffers praised the absolute value provided by the GTI and the overall fun factor. The Canyon, meanwhile, was saluted for being "the perfect size," not to mention its excellent build quality, feature-rich cabin and overall practicality. "It's truly a truck in the most honest sense of the word," Autoweek wrote of the Canyon. Scroll down for the full press release on the announcement from Autoweek, which includes comments from both Volkswagen and GMC. And then head over and read AW's full feature on the awards. Autoweek names Best of the Best/Car and Truck for 2015 Volkswagen Golf GTI and GMC Canyon signal a strong year for design, performance and value DETROIT, Dec. 16, 2014 /PRNewswire/ -- Today, Autoweek named the Volkswagen Golf GTI as its Best of the Best/Car for 2015, beating a group of finalists that includes the Alfa Romeo 4C, Ford Mustang and Mercedes-Benz C-class; and the GMC Canyon as its Best of the Best/Truck for 2015, besting the likes of the Chevrolet Colorado, Lincoln MKC and Porsche Macan. Autoweek evaluates every new or significantly updated model throughout the year and begins to identify the standouts. Performance, economy, fit and finish, design, value, significance to the auto industry and personal taste all combine to define the Best of the Best. Four cars and four trucks make the grade, and Autoweek editors put them through rigorous road-handling tests at Michigan International Speedway in Brooklyn, Mich. This is where a vehicle transcends the numbers and shows if design, performance and pure driving passion meld into an Autoweek Best of the Best pick.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
