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.

GMC SIerra Denali is ready to live the high life

Between the information for the 2014 Chevrolet Silverado High Country and the accidently leaked picture on GMC's consumer site, it didn't take much imagination to envision what the 2014 GMC Sierra Denali would be like. But here it is. Going on sale this fall, the 2014 Sierra Denali will continue to be the most luxurious pickup truck in the General Motors portfolio, while getting more power and technology than ever before.
Like previous models, the 2014 Sierra Denali stands out from lower Sierra models with a big cheese-grater chrome grille, 20-inch chrome wheels and body-color bumpers. Inside, the Denali gets plenty of leather with contrasting stitching, but this is where GMC really steps up from the Silverado High Country with real aluminum trim and a new customizable eight-inch driver display in the gauge cluster. Standard features will include heated and cooled front bucket seats, the Intellilink infotainment system with Bose audio, while the options list offers a Driver Alert Package (with forward collision alert and lane departure warning), a rear-seat entertainment system and a Z71 Off-Road Package.
As for power, the standard engine will be the 5.3-liter EcoTec3 V8 with its 355 horsepower, and the optional engine will be the new 6.2-liter V8. Although official power figures for the bigger engine aren't in yet, GM is finally putting some estimates on paper expecting around 420 horsepower and 450 pound-feet of torque to go with a 12,000-pound towing capacity. The new Sierra Denali will be available in either two- or four-wheel drive. Scroll down for more details listed in the official press release.

GM recalls 330,000 fullsize trucks for airbag replacement

General Motors has announced a recall of 330,198 fullsize pickups in the US in the aftermath of the announcement made on May 19 that doubled the number of vehicles being called in to replace Takata's defective airbag inflators. That announcement expanded the nationwide recall to an estimated 33.8 million vehicles in the US. Heavy Duty versions of the 2007 and 2008 Chevrolet Silverado and GMC Sierra are included in GM's move, for the purpose of replacing the passenger airbag inflators. The announcement made by the National Highway Traffic Safety Association cited long-term exposure to moisture as a possible cause of the inflator issues. GM says it isn't aware of any problems with the recalled pickups due to moisture, nor has it had any reports of crashes, injuries, or fatalities, and has not received any complaints. GM will notify owners, who can then take their trucks to the dealers to have them repaired free of charge. You'll find a statement from GM and the recall notice from NHTSA below.
