OnStar RemoteLink mobile app coming standard on all new GM vehicles

As an evolution and improvement of its OnStar technology, General Motors has announced that it will be expanding the RemoteLink Mobile App on most 2014 model year Chevrolet, Buick, GMC and Cadillac vehicles. The new, aptly named RemoteLink Key Fob Services will allow users to remotely operate all of the same systems as the car's key fob, including locking and unlocking the doors and remote starting (on vehicles equipped with a factory remote starter) using a smartphone.
These Key Fob Services will be free for five years - starting from the vehicle's delivery date - but the full suite of RemoteLink features will continue to be offered only with a subscription (trial or paid). These premium features include contacting a live adviser, getting turn-by-turn directions and remotely monitoring the vehicle's diagnostic systems.

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.

2015 Chevy Colorado, GMC Canyon airbag problem causes recall

The recall affects 2,432 vehicles, though only 138 had actually reached consumers.
General Motors quickly fixed an airbag-wiring problem with the 2015 Chevrolet Colorado and GMC Canyon, but is still conducting a small recall to repair the midsize trucks that are launching this fall.
