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.

Ram 1500 TRX spied with remote-reservoir shocks and supercharger whine

The highly anticipated Ram 1500 TRX, Ram's Ford F-150 Raptor rival, has been spied again. And the big news is all in the suspension. Compared with the last prototype we saw, this truck sits much higher, and it now has fender flares to cover the wider track. It looks like some of the extra width may be from slightly bigger tires and higher offset wheels. But those might not be the only factors. Looking closely, the rear wheels have eight lug nuts versus six on the front. The previous prototype had six lugs on the rear. So this version may have a beefier rear axle, maybe from the Ram 2500. That axle may be a bit wider. The suspension itself is clearly farther along, too. Up front, there are some burly looking lower control arms. But in the back, any suspension reinforcements are long gone, and the axle seems to be supported by equally beefy trailing arms. Most exciting are what appear to be fancy remote reservoir off-road shocks tucked in the rear wheel arches. They're covered by little black sacks to hide them. The Rebel TRX concept from a few years ago featured internal-bypass shocks, and the Ford F-150 Raptor features the same kind of shocks. That Ram TRX concept also had 13 inches of suspension travel at each corner. Besides the updated suspension, we're pleased to report that the TRX is still rocking Hellcat power. Our spy photographer tells us that there's very audible supercharger whine. He also caught the truck on video, and it sounds gravelly and angry. We're very much looking forward to the truck's launch, which should be sometime before 2022.

Fiat Chrysler Automobiles: The next five years

Unless you've been living under a rock for the past 24 hours, you've no doubt read about all of the big future product news coming out of Fiat Chrysler Automobiles today. We had individual brand reports from Chrysler, Dodge, Jeep, Ram, Alfa Romeo, Fiat, Maserati and even Ferrari, but in the interest of simplifying and summarizing, we're going to list out the hard facts once more. Of course, with all of this still off in the future, there's still the possibility that a few changes will be made. But as of what we know right now, here's what's coming, and what's going away.
