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.

Ford F-150, Chevy Silverado, Toyota Tundra flunk IIHS headlight test

The Insurance Institute for Highway Safety put pickup truck headlights to the test and found that the majority of them were equipped with subpar units. The 2017 Honda Ridgeline was the only truck to earn a rating of "good." The large pickup truck test was comprised of the: 2016 to 2017 GMC Sierra, 2017 Nissan Titan, 2016 Ram 1500, 2016 to 2017 Chevrolet Silverado, 2016 to 2017 Ford F-150, and 2016 to 2017 Toyota Tundra. The Sierra's headlights earned a rating of "acceptable," the headlights found on the Titan and Ram 1500 were found to be "marginal," and the ones on the Silverado, F-150, and Tundra were rated as "poor." IIHS claims the F-150 was the most disappointing out of the large pickup trucks as both its halogen and optional LED headlights failed to provide adequate visibility during testing. The Ridgeline (which earned a "good rating"), is usually considered a midsize or small truck, though IIHS included it in the field of large pickups. The headlights on the 2016 Chevrolet Colorado, 2016 GMC Canyon, 2016 Nissan Frontier, and 2016 to 2017 Toyota Tacoma, which made up the small pickup truck group, all earned a rating of "poor." The IIHS claimed the Colorado had the worst headlights of any truck that was tested, as the base vehicle's units were only able to illuminate up to 123 feet in front of the car. The Ridgeline's headlights, for reference, were able to illuminate up to 358 feet in front of the vehicle. To conduct its test, the IIHS utilizes a special tool to measure how far light is projected out of the headlights in different driving situations. The trucks' headlights were tested in a straight line and in corners, while vehicles with high-beam assist were given extra praise. The headlights on the pickup trucks also mimic the testing that was done on small SUVs and cars earlier this year. Next year, automakers will need to fit their vehicles with headlights that earn a rating of either good or acceptable to earn the IIHS Top Safety Pick+. Related Video:

Fernando Alonso just misses qualifying for Indy 500 on first day

Former Formula One world champion Fernando Alonso will need a clutch run on Sunday to qualify for the Indianapolis 500 on May 26 after he failed to seal a guaranteed spot on Saturday. The Spaniard tried fives times to put his McLaren Racing Chevrolet in the top 30, but wound up one spot short. He can make the 33-car field only through a six-car shootout on Sunday that will determine the race's final three drivers. "We have another chance to be in the race," Alonso, who is seeking to make his second Indy 500 field, told IndyCar TV. The Spaniard twice got inside the top 30 but both times was bumped outside the mark, with JR Hildebrand and Graham Rahal the final two drivers to seal qualifying spots. Britain's Pippa Mann will be the only woman in the race, qualifying 30th in 227.244 mph. Race positions 10-30 were determined during the day-long qualifying with Saturday's nine fastest drivers set to return on Sunday to decide pole. Spencer Pigot, driving the Ed Carpenter Racing Chevrolet, led qualifying with a four-lap average of 230.083 mph. He was followed by 2018 winner Will Power of Australia (230.081) and Simon Pagenaud of France (229.854). The troubles for Alonso, whose top four-lap average was 227.224 mph, were exacerbated by a punctured tire in his first qualifying run. "That didn't help," Alonso told reporters. "But, obviously, our performance has been quite bad all week. Quite poor." The Spaniard crashed his Chevrolet in practice on Wednesday and missed nearly two full days of practice while a backup car was prepared. He returned on Friday. Alonso said he was worried the McLaren team was "not ready for the challenge." "We've been slow. You see Juncos Racing crashing yesterday and being ready at 6 o'clock. That's impressive," he said. "For us, we've been a little bit slow on everything." Alonso is bidding to join Graham Hill as the only drivers to achieve the 'Triple Crown of Motorsport' with an Indy 500 victory. He previously won the Monaco Grand Prix and Le Mans 24 Hours race. He also won two Formula One drivers' titles.
