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.

May 2016: FCA wins, Ford and GM stumble on weak car volumes

The May 2016 sales numbers are in, and it looks as though FCA is getting some vindication for boldly cancelling two slow-selling car models. Meanwhile, Ford saw overall sales dip and GM's May volume took a big dive versus the same month in 2015. While Marchionne's decision to axe the Chrysler 200 and Dodge Dart has drawn criticism as being short-sighted, it's working for FCA so far. Although the Dart and 200 aren't out of production yet and no capacity has been shifted to crossover or trucks, May's numbers show that the emphasis on Jeep and Ram models makes sense right now. FCA's US sales rose 1 percent last month compared to May 2015, putting the year-to-date total at 955,186 vehicles, an increase of 6 percent compared to the same period last year. Standouts included the Jeep Renegade, Compass, and Patriot, and the Fiat 500X. Ram pickup sales were down 3 percent. And your fun fact is that Alfa Romeo sales were up precisely 10 percent, for a total of 44 4Cs sold versus 40 in the same month last year. At FoMoCo, the Ford brand took a hit to the tune of 6.4 percent from May 2015 to 2016, registering 226,190 sales last month. Lincoln showed improvement on its modest numbers, going from 9,174 to 9,807, a 6.9 percent increase. Overall, Ford was down 5.9 percent for the month to 235,997; despite the slump, year-to-date total Ford sales are up 4.2 percent to 1,112,939. Strong sellers included Escape, Expedition, F-Series, and Transit - big stuff. Most small and/or efficient models (Fiesta, Focus, Fusion, C-Max) saw sales slides. Fusion sales were also down, likely due to effects of model changeover to the freshened 2017 model. Ford has promised four new crossovers and SUVs by 2020 and if things keep trending this way the company will be able to sell them, but things could change in the next four years. GM saw the worst of it for domestic brands. Retail and fleet sales were down for each of the four divisions, with the May 2016 total dropping 18 percent to 240,450 vehicles. GM's year-to-date sales are down 5.0 percent in 2016 to 1,183,705. Both the Sierra and Silverado were down significantly, and the majority of Chevy, Buick, GMC, and Cadillac nameplates saw sales decreases, with both small cars and larger utilities included. Not even big stuff could help GM this month, it seems. We'll have more on the rest of the industry's May sales as those figures trickle in.

2019 GMC Sierra Denali First Drive Review | The more things change...

ST. JOHN'S, Newfoundland — Canadians love their GMCs. Both anecdotal and statistical evidence supports this. In certain areas of Canada, the Sierra outsells the Chevy Silverado. But in this area of Canada, Cape Spear, the morning fog and salt air are thick. This is the most eastern point in Canada, and the most eastern point of North America if you don't count Greenland. We woke up early and drove to the coast in the new 2019 GMC Sierra Denali, hoping to catch what was promised to be an absolutely spectacular sunrise. The sunrise was a no-go thanks to the fog, turning the sky into a grey mist that melted into the Atlantic. Still, if the world had an edge, this is what it would look like. Driving in an inspiring place like this invites introspection, and since we're in an GMC Sierra, why not examine the brand's place in the world? Recall that for years, a GMC showroom was just packed with slightly more expensive versions of other GM products. Badge engineering, if you will – a dirty word in our business, applied to such notable machines as the Cadillac Cimarron, Buick Terraza, Chevy Aveo and Saab 9-7X. Things, at least on the surface, seem to be changing. GMC says it's making a concerted effort to differentiate its product portfolio from the rest of GM, but the results have been mixed. The brands were supposed to have less product crossover. There's no GMC version of the Chevy Traverse and, initially, there was no Chevy equivalent of the GMC Acadia, though the new Blazer kills that advantage. The Equinox and Terrain are still basically the same vehicle, as are the new 2019 Silverado and 2019 Sierra. At least the two trucks look decidedly different. There's still a family resemblance, but most of the bodywork has been changed. Where the 2019 Silverado adopted some curves, the Sierra stuck with straight lines. Compare things like the headlights, wheel wells and doors. The Sierra still has a massive grille and — aside from the AT4 off-road trim — packs on as much chrome as a 1958 Cadillac, but that's what customers want these days. The Ford F-150 and Ram 1500 are no different in this regard, packing lots of chrome, hard edges, and frontal areas that would give passenger trains a run for their money. At first glance, you'd be hard pressed to tell the Sierra and Silverado's interiors apart from both each other and the outgoing models. It's basically the same design, though the Sierra makes do with some slightly nicer materials.
