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.

Chevy confirms 2016 Camaro will have wheels, brakes

Good news, everyone! Chevrolet has issued yet another round of teaser images and information about the sixth-generation Camaro, set to debut in Detroit on May 16. This time around, Chevy's teaser images confirm that the new car will not only have wheels and tires (Goodyear Eagle F1s, no less), but brakes as well. On top of that, we now know that the new Camaro will be 28-percent stiffer than the outgoing model. "The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly," GM said in a press release, which you can read below. We've already learned that the new coupe will be 200 pounds lighter than its predecessor, has a bunch of unique parts, and according to GM's Mark Reuss, will outperform the Ford Mustang in every way. Now, it's only a matter of time before we see the sixth-gen Camaro, but surely not before Chevy issues even more teasers and information.

The structural modeling led to the Gen 6 Camaro being 28 percent stiffer than the current model. "The modeling abilities of computer aided engineering are advancing at incredible rates," said Jim Karlavage, Camaro program engineering manager. "Today, we can accurately model opportunities to add torsional strength without adding unnecessary mass. The result is a lighter, stiffer structure that benefits every aspect of the driving experience." The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly. "The structural weight savings are compounded by opportunities to reduce un-sprung weight," said Karlavage.

Dodge Challenger SRT Hellcat vs. Chevrolet Camaro ZL1 in latest Head 2 Head

"Olympian" is one of the terms we use to signify the greatest height, the seat of the gods. Yet Mt. Olympus is the second-highest peak in the Balkans ranges, overshadowed by the crest at Musala in Bulgaria's Rila mountains. Both great heights, but one is a little higher. That's how we get the Olympian Chevy Camaro ZL1 pitched at the Musalic Dodge Challenger SRT Hellcat in Motor Trend's latest episode of Head 2 Head. The side-by-side spec sheet is filled with farcical numbers. For the ZL1, that's a 6.2-liter V8 with 580 horsepower, 556 pound-feet of torque, a 4,051-pound curb weight, 0-to-60 miles per hour in 3.9 seconds, a quarter-mile time of 12.2 seconds and a base price of just $57,800. Opposing that, the Hellcat wrings out its 6.2-liter V8 for 707 hp, 650 lb-ft of torque, weighs 4,449 pounds, does the quarter in 11.7 seconds and has a base price of just $60,990. Except in the case of the Hellcat, when Motor Trend put it on the dyno the machine spit out a reading of 672 hp and 606 lb-ft at the wheels. If there's a 10-percent driveline loss through those beefed-up internals and heavy-duty eight-speed transmission, that means the Hellcat is actually rated at about 750 horsepower and 700 lb-ft. But once they get put on a closed-off strip of coast road in Northern California, there are only a few strands of hair between their respective performances. That's not the case for they sensations provide; host Jonny Lieberman calls one of them, "One of the most incredible cars ever made," and says, "It changes everything."
