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.

Sunday Drive: From a mid-engine 'Vette to a restomod RV

Automotive enthusiasts are a diverse bunch. As proof, we present last week's top posts on Autoblog, starting with some really good spy photos of the upcoming mid-engine Chevrolet Corvette. Will it be sold alongside a classic front-engine 'Vette? We have no idea, but we can't wait to find out. Up next is a pickup truck. Can't get much further from a supercar, right? At least both the Corvette and the 2019 Ram 1500 – which will debut a radical new design that appears to eschew the mini big-rig look of past Rams in favor of something more refined – are both American. Decidedly not American? The Mercedes-Benz G-Class SUV. The boxy off-road 'ute looks a heck of a lot like the old one, which is probably a good thing, but we know it'll be fancier and more luxurious than ever before. Check out the leaked images below. Also hailing from Germany, but sharing absolutely nothing else in common at all, is the Audi A4 Allroad. We've been driving this all-wheel-drive wagon for a while now, and we like it quite a bit. And, last but not least, is a 1959 bus that's been converted into an RV. Like we said, y'all certainly are a diverse bunch.

GM drops diesel engines for 2020 Chevy Equinox and GMC Terrain crossovers

GM is officially discontinuing the diesel engine in the Chevy Equinox and GMC Terrain for the 2020 model year. The 1.6-liter turbodiesel was always an oddball of an engine in the compact crossover segment, and now the experiment has come to an end. The Car Connection initially reported the news, and a GMC spokesperson, Stuart Fowle, confirmed it to us this morning.  “A huge majority of our Terrain customers have opted for one of our two gas engines," says Fowle. We canÂ’t say this eventuality comes as a massive surprise, as we saw news from couple of months ago that GM was dropping all-wheel drive from the diesel-powered cars for 2020. Low demand was cited as the reason for that cull, and itÂ’s the same for the little GM crossovers this time around, too. These vehicles were the only ones powered with a diesel engine in their class, but thatÂ’s going to be changing. Just as GM is going away from the diesel, Mazda is finally bringing its diesel to market in the CX-5. YouÂ’ll only be able to get that engine in the most expensive ($42,045) trim level, combined with all-wheel drive, though. The cheapest Equinox diesel starts at a comparably low $30,795. ThatÂ’s a $2,400 upcharge over the base 1.5-liter turbo four-cylinder, and the value is questionable. Mileage is better, but diesel fuel is more expensive. Towing capability didnÂ’t increase over the base engineÂ’s 1,500-pound capacity, but the extra torque around town was nice. As diesels go in the U.S., this one was rather rough and noisy, possibly contributing to some turning their noses up after a test drive. Perhaps another reason for its demise was that the much quicker 2.0-liter turbo Equinox was only $100 more than the diesel. This engine offered significantly better towing at 3,500 pounds, too. You can read all about what we thought of the diesel in our first drive review here, but the 2019 model year is the last one if you had it on your shortlist.
