GM CEO to meet with U.S. lawmakers over job cuts

WASHINGTON — General Motors Co Chief Executive Mary Barra plans to visit Capitol Hill next week to discuss the company's plans to halt production at five plants in North America next year and cut up to 15,000 jobs, two congressional aides said on Friday. GM has come under harsh criticism from lawmakers from both major political parties, and from President Donald Trump, since Monday when it announced the biggest restructuring for the U.S. No. 1 carmaker since its bankruptcy a decade ago. Barra is expected to meet with lawmakers from Michigan and Ohio, where GM plans to shutter three plants, as well as senior leaders in Congress. GM did not immediately comment. Barra has been calling lawmakers this week to explain the decision to end production. Trump has threatened to revoke subsidies for GM. The Detroit automaker plans to halt production next year at three assembly plants: the Lordstown small-car factory near Youngstown, Ohio; the Detroit-Hamtramck complex in Detroit; and the Oshawa, Ontario, assembly complex near Toronto. It will also stop building several models now assembled at those plants, including the Chevrolet Cruze, the Chevrolet Volt hybrid, the Cadillac CT6 and the Buick LaCrosse. Additionally, GM plans to shutter the Warren transmission plant outside Detroit and a plant that makes electric motors and drivetrains outside Baltimore, Maryland. The Cruze compact car will be discontinued in the U.S. market in 2019, although GM may continue building it in Mexico for other markets, Barra said. Reporting by David Shepardson. Related Video:

'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).

Base GMC Hummer EV2 reportedly dead for the planned 2025 launch year

Remember October 2021? That's when GMC divulged trims and pricing for the Hummer EV pickup range. It started with the Edition 1, asking around $110,000 before it sold out. Then would come the EV3X in fall 2022 for $99,995, followed by the  EV2X in the spring of 2023, asking $89,995. And for this year, shoppers were meant to get the option of a 'bargain' entry, the EV2-without-the-X that kept the dual motors but swapped for a less zippy 400-volt electric architecture and a smaller battery pack able to power a 250-mile estimated range. At the time, we were told the EV2 would open the MSRP bidding at $79,995. Spring is officially here, the EV2 isn't, and GM Authority cites unnamed sources when writing "there will be no 2 model for the 2025 model year" outside the 2X. Normally, automakers kill the low-hanging fruit after putting it on sale; the Hummer EV has, again, upended expectations. Therefore, your 2024 GMC Hummer EV pickup lineup after the $2,295 destination charge costs: EV2X Pickup: $98,845  EV3X Pickup: $106,945 EV3X Omega Edition Pickup: $150,295 On the SUV side, the MSRPs are almost carbon copies:   EV2X SUV: $98,845  EV3X SUV: $106,945 EV3X Omega Edition SUV: $130,300 For both body styles, keep in mind that Interstellar White is the only freebie exterior hue. Void black adds $495 to the price, five other colors cost $625, Afterburner Tintcoat orange runs $1,225.  The limited-edition Omega variant builds on the 3X trim with exclusive Neptune Blue Matte paint, the $9,995 Extreme Off-Road Package, exclusive 18-inch wheels, unique interior carpeting, a transparent roof and the MultiPro tailgate with a Kicker audio system on the pickup. Both trucks also get 35-inch mud-terrain tires, underbody skid plates and additional off-road camera views. The price disparity is partly because the Omega Edition pickup is packs a 24-module battery, the SUV gets a 20-module battery. This trim is only available to existing order holders. Speaking of which, the otherworldly EV is still going to be a few years' wait for some, but more reservation holders are already enjoying deliveries this year as GM continues to open the factory taps. GMC sold two examples of the Hummer EV in the first quarter of last year, around the time it has 65,000 potential buyers on the reservation list, and 3,260 units for all of 2023. In the first three months of this year, GMC sold 1,668 trucks.  Related video:
