GMC reveals updated 2016 Sierra

It was just the other day that Chevy revealed the face of the new 2016 Silverado. And as might have been expected, sister brand GMC has followed up by unveiling its version in the facelifted 2016 Sierra pickup – just two and a half years since the current all-new model was rolled out. Though details released thus far remain few and far between, GMC has revealed more images of the new Sierra – in SLT, Denali and All Terrain trim levels – than Chevy did of the updated Silverado. It's got new headlights, fog lamps, and C-shaped daytime running lights and taillights, all using LED elements. It's arguably a more muscular look than the Chevy version, and with more chrome than the toned-down Silverado. That is, at least, in SLT and Denali trims. The All Terrain version looks more in line with the similarly off-road-focused Silverado Z71 and its color-keyed treatment. The changes ought to help GMC keep up the momentum that has seen its sales rise year-over-year every month over the past twelve. The interior shots indicate that the new Sierra will incorporate Apple CarPlay like GM is installing in so many models across its various brand ranges. But we'll have to wait a little while longer for all the details.

With exterior styling as its top reason for purchase, the new truck adds key design elements: LED "C-shaped" signature daytime running lights and LED headlights; new front fascia and grilles for each trim level; new LED fog lamps; new bumpers; and new "C-shaped" LED taillights. The new Sierra will be available in the fourth quarter of this year, with additional details and information on the new model released in the coming months.

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.

GM cutting vehicle trim options to save money for electrification

Information continues to filter out about GM's plans based on comments the automaker made during its Capital Markets Day event in February. GM President Mark Reuss said the company's push to save money by rationalizing the number of build combinations will continue in 2020, carrying on the work done in 2019. As GM Authority covers, last year, the carmaker cut 3,500 components across model lines, a 12% drop in the number of parts it needed to stock in its plants. Reuss used the next-generation Chevolet Equinox and GMC Terrain as examples for more cost efficiencies, saying build possibilities — which include international markets and their options — will be cut by more than 50%, and use more shared parts. "We will reduce total trim levels on Equinox and Terrain from eight to six," Reuss said, "reduce engine variants from 11 to 5, reduce build combinations from more than 200 to less than 100 per program, and see significant cost savings of an already paid-for architecture that took the mass out, helping us self-fund electrification programs." GM will plow a large amount of the money it saves into its ambitious EV program. In 2017, the automaker said it intends to have 20 electric vehicles on the market by the end of 2023, some of which could be shared between brands. An automotive analyst at Seeking Alpha and a piece in Automobile attempted to put specifics to what we should expect. As Automobile points out, the first two EVs in the 20-car program are already on sale, being the Ariv Meld and Ariv Merge eBikes available in Belgium and The Netherlands. We've seen the Cruise Origin autonomous rideshare taxi, although we don't know when it will hit the road. The next three, which we should see in the metal shortly, are two Cadillac EVs and the GMC Hummer EV pickup. The Cadillac pair are expected to be sized like the XT4 and XT5, and along with the Hummer, should hit the market starting in late 2021.
