GM already raising prices on 2014 Silverado and Sierra pickups

General Motors must be pretty pleased with sales of its two newest pickups, the GMC Sierra and Chevrolet Silverado, as it's announced price hikes for both models, as part of a planned price tweak.
Prices will be bumped by as much as $1,500, although weirdly, they'll be offset by as much as $1,500 in cash-back offers through the end of October. Fox Business reports that GM spokesman Jim Cain said of the price hike, "With the sell down of the '13 models nearly complete, this price adjustment was planned and is a normal part of business."
The move, as Fox is quick to point out, is an interesting one, as sales of the twin pickups struggled last month relative to the Ford F-Series, while both of GM's crosstown competitors have been aggressively undercutting Silverado and Sierra prices. The F-150 starts at $24,070 and the Ram 1500 comes in at $23,600, not counting any cash on the hood. A base Silverado, meanwhile, retails at $25,575.

2019 GMC Sierra CarbonPro Edition pricing starts above $65,000

GMC is hard at work building carbon fiber beds for its CarbonPro trucks, so it's fitting that the company has finally released pricing for the 2019 GMC Sierra CarbonPro Edition. It's not cheap by any measure. The most "affordable" for 2019 is the AT4 version starting at $66,635. It's also available in Denali trim, and that version starts at $70,020. Both represent an increase of $8,000 to $9,000 more over the base AT4 and Denali models. That may seem like a lot to go from a steel bed to a carbon fiber one, but you're getting more than the bed for that money. GMC also includes unique badging, a Bluetooth bed speaker, rear-camera mirror, surround vision cameras, automatic emergency braking, lane-keep assist, automatic headlights, power side steps, a sunroof, trailer tire pressure monitoring and a color heads-up display to both models. The AT4 specifically gets a Bose sound system, navigation, parking sensors and a cat-back exhaust, too. The Denali adds unique 22-inch wheels. Both only come with the 6.2-liter V8 and 10-speed automatic. To equip a regular GMC Sierra AT4 similarly to the CarbonPro Edition, the price comes out to $64,110. The Denali comparably equipped to the CarbonPro is $67,940. So the bed itself is about $2,000 to $3,000. The 2019 GMC Sierra CarbonPro Edition trucks should be reaching dealers very soon. They will soon be supplanted by the 2020 version, which will add the new 3.0-liter diesel inline-six as an engine option. The AT4 CarbonPro will get some extra black accents for 2020, too.

'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).
