Chevrolet has released a two-part documentary series sharing the story behind the making of the 2020 Chevrolet Corvette. The 2020 Corvette is the first model year of the vehicle's eighth generation and the first to offer a mid-engine setup.

The first part of "Revolution: The Mid-Engine Corvette Development Story" showcases the design story of the 'Vette via unique footage and in-depth interviews. Designers talk about the evolution of the Corvette including how its design was dictated by the function of the car and informed by the heritage of the Corvette line, which stretches back to the 1950s.

Additionally, designers dig into the impact of the annual 24 Hours of Le Mans has had on the model line, and how on-the-track performance impacts the vehicle designed for the average customer.

The 2020 Corvette was designed as new from the ground up with the mid-engine format dictating much of what went where. It was in 2011 that the company brought back the idea for a mid-engine 'Vette and development ticked along through the vehicle's debut day in 2019. Engineering work on more performance-focused versions of the Corvette is ongoing.

As part of the process, Chevrolet developed several scale clay models. General Motors recycles its clay as part of its sustainability initiatives.

The documentary also features a look into the design of the interior of the car. The driver-focused design features unique attributes including a raised button bar that separates the driver from the passenger of the coupe.

Chevrolet closes the first part of the documentary showing a behind-the-scenes look at the debut of the car, which took place in Orange County, California.

The second episode of the series features the engineering story.

The two parts equal about 20 minutes of storytelling. Chevy released the first part of the documentary on December 22. The second installment was revealed today on the company's YouTube page. Watch both parts below.

The ZR2 is a beefy off-road pickup.

Chevrolet

Chevrolet has added a beefed-up version of its half-ton pickup to the 2022 Silverado lineup that has more capability and comfort for towing and hauling loads, traveling to hard jobs over a variety of road surfaces and a better 4WD game for backcountry travel. I recently joined the Bow-Tie brand for a 200-mile-long evaluation of the first-ever Chevy ZR2. Our day-long test drive took us from the popular desert playground of Palm Springs, located in a verdant valley surrounded by 5,000 to 10,000-foot mountains, to swaths of nearby desert. There, we traveled along a collection of dirt trails in Joshua Tree National Forest and on a 4WD mining trail to abandoned gold mines, with rugged topography that allowed us to try out the truck’s updated hardware that has been engineered to bring an ease of operation and safety for motoring over tough and technical terrain.

Chevy has made some significant changes to the 2022 Silverado lineup from outside to in and has added Super Cruise, a hands-free drive mode that we were able to try out on local highways in the Palm Springs environs, as we also checked out different trim levels and new technologies. Updates of note are new interior styling, freshened materials and premium trims; a new dashboard and digital displays with a 12.3-inch fully digital gauge cluster and a 13.4-inch touchscreen infotainment system (with Google’s Maps, Assistant and Play Store as well as Android Auto and Apple CarPlay); and an electronic shifter mounted to the center console. However, our primary task was to focus on the all-new ZR2 that has been set up with a 420-hp 6.2-liter V-8 engine, rides on 33-inch Goodyear Wrangler Territory tires, boasts a new suspension with Multimatic spool-valve dampers, and has electronic-locking front and rear differentials. Elements of the ZR2 and this moniker have been used previously on a special edition of Chevy’s compact truck.

In addition to its functional features, the new Silverado ZR2 stands apart from its stablemates by a collection of unique design cues, including a distinctive front end with a new black hood insert; a large-sized grille with a hollowed-out ‘flow-tie’ emblem for increased air flow and integrated lighting; wheel moldings, ZR2 badges, unique 18-inch wheels and an exclusive Jet Black/Graystone leather-trimmed interior matched with an appealing dark trim. Overall, the truck looks slightly aggressive and fit. The 2022 Chevrolet Silverado ZR2 competes with other full-sized desert-running and off-road trucks from Ford and Ram. It’s only offered with a crew-cab body style and either the short- or standard-length cargo boxes with an optional Multi-Flex Tailgate. On sale now, it starts at $67,600 (plus $1,695 destination and delivery)

Chevy’s flagship off-road pickup can tow 8,900 pounds with a conventional trailer hitch and haul up to 1,440 pounds of payload, with more comfortable ride as a result of the spool-valved dampers and specially-tuned springs that bring increased wheel travel when compared to the Trail Boss trim, for instance. This also translates to improved control and greater safety on the road, which we found impressive during our highway driving. The truck has a number of new standard safety features, as well.

Added to Chevy’s in-house testing of the truck in everyday driving and extremes, we learned that the new pickup has been put to the test over the past three years by Chad Hall, who is a highly-respected off-roader and noted desert racer. The production truck and Hall’s prototype race truck share most of the major chassis and drivetrain components, including the robust ladder-type frame; the 420-horsepower V-8 and 10-speed automatic transmission; transfer case; front and rear differentials; plus the front and transfer case skid plates, says Chevy. (See below for more info on Hall’s racing success in this truck.)

We sampled a number of the truck’s technologies during our day-long drive, checking the boxes for both high-speed desert-running and slow-speed rock crawling. Overall, there was good power on tap with plenty of torque to move the half-ton’s 5,800-pound mass, smooth shifts from the 10-speed transmission, good brakes to slow our momentum when needed, and a comfortable ride- even over rugged roads and washboard.

I was excited to experience the ZR2’s talents on some isolated backcountry roads including the Old Dale and Black Eagle Mine Roads 4WD trail, where posted signage warned “Proceed at your own risk: Deep sand and rocks-- stranded drivers have died from heat exposure on park roads.” Truth is, this is just the kind of picturesque and formidable place that 4WD enthusiasts love to explore with a truck that can take you there—and bring you back safely.

What makes the ZR2 with its rear leaf-spring set-up abona-fide off-roader? In front are tow hooks and a skid plate underneath the high-mounted steel front bumper, with a 31.8-degree approach angle. Other numbers of note are the: 23.4 breakover angle; 23.3 departure angle; 11.2 inches of ground clearance; with 9.84 inches of suspension travel in front and 10.62 inches in the rear. Its width is 81.2 inches, which helps compared to some of its competitors, as it is more “parkable” in many garages and we found it maneuvered well when navigating through narrow sections of rock. Engineers have also repositioned the dual exhaust for added protection.

One of the truck’s top cool new features is the selectable Terrain Mode that allows for one-pedal driving; this cruise-control-like technology is particularly useful for motoring over rocks and up and down steep slopes. To engage, we locked the ZR2 into 4WD Low, set first gear and let the engineering do the driving, using the throttle to increase speed and the brake to decrease speed, when needed. A forward-facing camera provides visibility to the front and sides, as well as to the back which is another great feature for navigating technical terrain.

*Fuel economy estimates sit at 14 mpg in the city, 17 on the highway and 15 combined. the 24-gallon ZR2’s 360-mile range.

**FAST FACT: Chad Hall Racing also helped test the Chevy Colorado ZR2 off-road technologies in competition — and is still going strong with them. The Colorado ZR2 has been racing since 2017 in the Best in The Desert series and is the only truck in its class to have finished every race entered. It has accumulated more than 22,500 miles of racing experience.

The IIHS may increase the speeds it uses to test advanced driver aids.

Insurance Institute for Highway Safety

The Insurance Institute for Highway Safety (IIHS) recently announced that it is considering changing the speeds it uses to test vehicle-to-vehicle front crash prevention systems. The agency currently tests the systems at 12 and 25 mph, but says that the speeds don't accurately represent the types of crashes the safety tech is meant to prevent.

Automatic emergency braking (AEB) is designed to notify of a possible collision and help respond with automatic application of braking. Just like a human using the brake pedal, it can stop the car, but higher speeds make it difficult to stop in time. The new tests would be conducted at 35 to 45 mph, which is the range where a large number of rear-end crashes occur. As Automotive News noted, an IIHS study showed 43 percent of rear-end crashes occur at speeds of 45 mph or less, so it's important to have a test that shows how well the tech performs at those levels.

A whopping 85 percent of 2022 vehicles earned a "Superior" rating in the current testing regime, so the IIHS will remove it from 2023 testing and Top Safety Pick award evaluations. Their view is that, since the majority of vehicles meet the criteria, it's no longer an accurate way of evaluating performance. In its place, the agency introduced a night test for automatic emergency braking systems that will begin next year.
