GM recalls full-size truck, SUVs and vans over faulty shifter mechanism

Twelve different General Motors vehicles from the 2013 model year, up to 54,686 units in total, are being recalled over two potential issues with their steering columns. The models in question, all full-size trucks, SUVs or vans, are the: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe, and GMC Savana, Sierra, Yukon and Yukon XL.
The affected vehicles were built with a fractured parking lock cable or "a malformed steering column lock actuator gear in the lock module assembly." As a consequence, they could shift out of park without the brake pedal being applied or with the key removed or in the off position.
A bulletin from the National Highway Traffic Safety Administration indicates that the recall should begin on January 17. GM will notify owners, at which time they can take their vehicles to their dealers for repair free of charge. Have a look at the bulletin below for more information.

The story of the 2014 Chevrolet SS: "Luxury, power, refinement, handling"

Not including the women and men who built it, the 2014 Chevrolet SS has only been seen in person by a piddling number of people - fewer humans than would fill the gymnasium at a high school volleyball game. Not including the men and women who built it, no one has driven it. Even so, it is already saddled with two controversies: the way it looks and the way it shifts.
First to that shifting. Did we love the last Americanized Holden, the awesomely sportsome Pontiac G8 GXP, and its six-speed manual? Of course. Do we wish the SS came with a six-speed manual? Of course. But we'd like a toboggan to come with a manual transmission. We'd put a manual transmission on a weasel if we could because we're just wired that way; if it moves, it should come with a stick and a clutch. Or at least the option.
Let's climb down off the ledge, though. We haven't driven the SS and we have no idea how good (or not) the automatic is. And the Hobson's Choice in transmissions when it comes to sport sedans like the BMW M5, Mercedes-Benz E63 AMG and Jaguar XFR-S and, oh yeah, cars-that-really-should-have-manuals like the Audi R8 and Nissan GT-R and Porsche 918 and every single Lamborghini and Ferrari, for instance, hasn't stopped us from enjoying what is clearly the gruesome, dual-clutched demise of Western automotive civilization. Because in spite of our ululations at the dying of the six-speed light, we understand.

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.
