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.

2020 GMC Sierra 1500 Interior Driveway Test | Still lagging behind

GM has caught nothing but grief for the interiors of its full-size pickups since they were redesigned. Some of it is about perspective. Ram blew everybody away with the new 1500’s interior, but it's not like the Ford F-150 is embarrassed by it. Chevy and GMC are. Even a top-shelf Sierra Denali doesnÂ’t live up to the luxurious environment its price tag would promise.  The trim of Sierra we're testing is an AT4, though. ThatÂ’s the light off-roading version of the Sierra thatÂ’s mechanically the same as the Silverado Trail Boss we recently reviewed. Looking at the interior from a pure functionality standpoint, the Sierra is perfectly fine at performing its truck duties. The seats are wide, flat and comfortable. It has huge armrests on both sides so you can stretch out as much as your truck stretches the boundaries of the road (seriously, this thing is huge). All the buttons in the center stack are well-labeled, easily found and big enough to stab away at without hitting the wrong one. It even has a volume and tuning knob. Yeehaw!  But look at the design. And the styling, or lack thereof. ItÂ’s plain and lacking in imagination. The whole center stack is just one big slab of black plastic, and the only splashes of color or style to distinguish it visually are bits of silver surrounding knobs and bits of gray surrounding air vents. That's certainly not enough to make it attractive. There are token pieces of "wood" inserted on Denali models, but they're almost hidden away along the center console and doors.  The screen looks as if itÂ’s scrunched into the top of the stack due to the vents curving in on both sides, making it look smaller than its perfectly acceptable 8-inch size. That just makes it more obvious that GM doesn't offer something to challenge the gigantic 12-inch optional screen on the Ram 1500. Not good, because size does matter when it comes to trucks, even if it's measured in a touchscreen's inches rather than engine displacement. LetÂ’s not discount how good all of the tech is in the Sierra 1500, though. GMÂ’s infotainment software that runs on the screen is glitch-free and runs like lightning through screens and menus. The performance is impressive, and of course both Apple CarPlay and Android Auto are on board.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
