Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.

2019 Ram 1500 eTorque Drivers' Notes Review | Filling in the gaps

When the 2019 Ram 1500 debuted earlier this year at the 2018 Detroit Auto Show, the biggest news was arguably the addition of the 48-volt mild hybrid system. Dubbed eTorque, the system is standard on V6-equipped models and a $1,450 option on trucks with the 5.7-liter Hemi V8. It's not a hybrid in the traditional sense. Despite Ram's claim that the system adds up to 130 pound-feet of torque on the V8, it only does so for a fraction of a second and doesn't actually change the engine's total output. You'd be hard pressed to notice a difference if you didn't know the system was there. But that's kind of the point. There's been a lot of confusion about what eTorque is and how the system works. Much of that falls on FCA's shoulders. The automaker didn't do a great job of explaining the whole thing, leaving us to work out much of it for ourselves. This isn't meant to boost performance, towing or payload. The Ram eTorque can't run on battery power, so don't expect a Toyota Prius with a bed and wood trim. It's here to make the truck just a little bit more efficient by improving areas where conventional internal-combustion engine's fall short. The eTorque system replaces the engine's alternator with a small, belt-driven electric motor. On the V6, the motor is part of the water pump assembly and driven by that belt; the V8 uses a dedicated belt that's separate from the other accessories. A small battery pack is mounted upright behind the rear seats inside the truck's cabin. There's also a DC-to-DC converter to charge the battery and convert 48 volts down to 12 to power the truck's normal systems. Visually, the only difference between an eTorque-equipped model and a standard one is a small metal box at the top of the engine. There's no badging and the battery pack can't be seen, even with the rear seats folded up. The system is designed to be as seamless and innocuous as possible. The auto start/stop system spins up the engine a little quicker. Shifts from the eight-speed ZF automatic transmission are a little smoother as the eTorque system smooths out and fills in the gaps. It does so for a fraction of a second, but it works its magic often. Big gains in fuel economy have already been made. It's going to take things like Ram's eTorque system to improve internal combustion engines from here on out. Editor-in-Chief Greg Migliore: I'd like to say I noticed a huge difference between the Ram eTorque and the regular Ram, but I didn't. That's how it's supposed to work.

Stellantis will enter joint venture with Samsung SDI for EV batteries

SEOUL — South Korean battery maker Samsung SDI Co Ltd and global automaker Stellantis NV have agreed to jointly produce electric vehicle (EV) batteries for the North American market, a person familiar with the matter said on Tuesday. Samsung SDI, an affiliate of South Korean tech giant Samsung Electronics, already has EV battery plants in South Korea, China and Hungary, which supply customers such as BMW and Ford. "The two companies (Samsung SDI and Stellantis) have struck a MOU (memorandum of understanding) to produce EV batteries for North America," the person with knowledge of the matter told Reuters. The source spoke of condition of anonymity because of the sensitivity of the matter. The person said the location of the battery joint venture is under review and will be announced later. In July, Reuters reported that Samsung SDI may build a battery plant in the United States, citing a company source. South Korea's Yonhap news agency earlier reported the two companies plan to build a factory in the United States, citing industry sources. Samsung SDI and Stellantis did not have immediate comment when reached by Reuters. Stellantis on Monday struck a preliminary deal with battery maker South Korea's LG Energy Solution (LGES) to produce battery cells and modules for North America. Shares of Samsung SDI were up 2.6% as of 0300 GMT, versus a 0.6% rise in the KOSPI benchmark index.
