Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

More than 5,500 people tried to get the 2016 Chevy COPO Camaro

It's stating the obvious, but the 2016 Chevy COPO Camaro is popular with enthusiasts. So much so, it's attracted more than 5,500 hand raisers, General Motors said Tuesday at an event to show off the company's new Performance and Racing Center in Pontiac, MI. Unfortunately for drag racing fans, Chevy will only sell 69 of them, as it has for the last four years. The COPO Camaro can be configured for the NHRA Stock and Super Stock classes. It comes with racing-tuned chassis pieces and a solid rear axle. Power choices include 5.7-, 6.2- and 7.0-liter V8 engines. About half of COPO Camaro owners race their cars, and the rest keep them as collectibles. Jim Campbell, GM vice president of Performance Vehicles and Motorsports, wouldn't say if the COPO is a profitable venture, but noted the fire-breathing dragster raises the image of Chevy and Camaro. "It makes sense for our business from a number of perspectives," he said. The first COPO Camaro, a Courtney Force-styled racecar that was revealed in November at the SEMA Show in Las Vegas, hammered for $300,000 at the Barrett-Jackson auction last month. The proceeds went to the United Way. Campbell said low COPO production keeps interest high. Enthusiasts can also build their own COPOs by buying a rolling chassis and a crate motor, though those are not viewed by collectors in the same manner as GM factory-built creations. The COPO Camaro's V8 is one of several competition engines designed, built, and validated at the GM Performance and Racing Center. The Corvette C7R's 5.5-liter V8 and the Cadillac ATSV.R's 3.6-liter twin-turbo V6 are two more. Chevy calibrates and conducts dynamometer testing on its 2.2-liter V6 for IndyCar and performs design work on its NASCAR V8 at the facility, which existed previously at another location in Michigan.

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.
