There's zero chance that The Mercedes-Benz EQC 4x4² will come to life as is, but that doesn't stop one from dreaming. Designed to be "an electric car of extremes", the model was designed to move the traditional thoughts of electric mobility away from city centers and onto more rugged terrain.

The EQC 4x4² was developed by a cross-departmental team under development engineer Jürgen Eberle, which has already been responsible for another daring off-roader, the E 400 All-Terrain 4x4². The new model can drive through sand and on rocky terrain, and through mountain streams.

It's capable of helping drivers stay off the grid for a spell. A roof tent and inflatable dinghy make adventuring with the concept even more possible.

Ground clearance? It has that in gobs. At 293 millimeters, EQC 4x4² has more than twice the ground clearance of the typical EQC production mode. This enables 40 centimeters (just over 15 inches) of water fording depth. Engineers have attached the vehicle's unique suspension at the same mounting points as the standard component.

Traditionally, off-roaders like to be able to listen their engine from inside the cabin to hear if it's operating correctly. With an all-electric powertrain, such as that in the EQC, there's no engine noise (because there's no engine) so drivers are able to create their own sound experience, whether it's rolling down the windows to enjoy nature or turning up the volume on the stereo. The model does use an external noise generator (Acoustic Vehicle Alert System, AVAS) as required by law to reproduce sounds. It is housed in the car's headlight surrounds.

While this model won't be arriving at dealerships anytime soon, it is a nod in the direction of what's next for Mercedes. It's likely that this concept was developed as part of a larger off-roading testing program for the company's existing and forthcoming fleet of electric vehicles.

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 CX-50 is surpsingly capable off-road.

Mazda

I have driven all of the Mazda vehicles that have been sold in the US market over the past three decades. On everyday roads and on racetracks. I’ve appreciated their “zoom-zoom”. Good power. Punchy torque just where it was needed. Well-balanced and sporty handling. A bit of growl for the versions that called for it. Plus, tasteful-but-modest styling and more or less elbow room, depending on the model. Mazda’s have been made for sports-car enthusiasts and to ferry families. But, I had never known a Mazda called an “overlander”. Until now.

2023 Mazda CX-50Towing capacity extends to 2,000 pounds.Mazda

The 2023 Mazda CX-50 moves this traction-sophisticated automaker into the lands where the pavement ends and now takes the brand ‘off-track’. Although it’s not a new thing for many of today’s carmakers to add a backcountry model or two to their lineup, it’s new for Mazda. I traveled to Santa Barbara, California to check out this all-new crossover built on Mazda’s seventh-generation small SUV platform that is shared with the smaller CX-30. This 5-passenger utility is longer, lower and wider than the CX-5 that rides on the previous generation’s underpinnings. The CX-50 has been crafted with a roomier second row and more cargo room for the goods and gear that weekend warriors and adventurers want to carry.

The CX-50 comes with a choice of two engines: a 2.5-liter, 4-cylinder engine with cylinder deactivation that gets 187 horsepower and 186 pound-feet of torque, and Mazda’s Skyactiv-G 2.5-liter turbo-charged powerplant with 256 horsepower and 320 pound-feet of torque; both shift through a six-speed automatic transmission. The sport ute can tow up to 2,000 lbs. with the naturally aspirated motor and up to 3,500 lbs. with the turbo-charged mill and Intelligent Drive Select (Mi-Drive) that brings a tow mode as well as Normal, Sport and Off-Road. The newest Mazda model has been made for North America only and is built in Alabama. It is the first Mazda vehicle with auto start/stop that can be deactivated.

The new crossover starts at $26,800 and comes in S, S Select, S Preferred, S Preferred Plus, S Premium, and S Premium Plus with the base motor. Turb-charged versions come in Turbo, Turbo Premium, and Turbo Premium Plus that tops out at close to $42,000. A long list of technology and safety features are standard or available. Mazda says that Meridian, a fourth turbo trim will arrive soon with even more off-road cred; it will be set up with 18-inch black wheels AT, hood graphics and other backcountry goodies.

When you look at the CX-50, the first thing you’ll notice is exterior styling that speaks to its adventure-ready mission. Muscular bodywork, such as extra cladding, wide fender flairs and larger, more aggressive tires mean that this crossover has been designed not only to give a nod to the looks of a rugged crossover but to provide enhanced traction and a tad more suspension stretch for motoring over uneven terrain and along bumpy dirt roads. Planted on its haunches with functional air vents, it eschews minivan styling with a low and wide footprint that allows owners to have easy access to high-strength roof rails for loading gear on top; the roof has been made stronger than other Mazda crossovers to accommodate heavier loads, such as a roof-top tent. A panoramic moonroof- a first for Mazda- and attractive antiglare hood graphics and are tasteful additions.

The interior is attractive and roomy, with horizontal lines and “cleanable” surfaces as a nod to outdoor endeavors. Our Turbo Premium Plus model had bright orange reverse stitching that popped the cabin that has been crafted with uplevel trims and materials and brought heads-up display. A 7-inch infotainment screen is standard, while the top models get a 10.25-inch version. A wireless charging pad and Apple CarPlay and Android Auto are standard on all trims. Of note, is the rear power and programmable liftgate to the wide and deep rear cargo compartment, with a load floor that flush with the liftgate opening to help slide heavy items in and out of the back. An available line of cargo accessories makes stowage easier.

How did it handle over the 200-plus miles of our ride and drive? The Turbo Premium Plus CX-50 offers a lot like; many of its driving attributes are consistent with Mazda’s tuning and handling priorities across its product line. Traveling along coastal highways, carving mountainous twisties with tight turns and accelerating on flat and straight well-graded pavement, it has great Mazda manners: i.e., there is enough power and torque in the right bandwidth to move it well; precise steering with a slightly heavily-weighted leather-wrapped steering wheel and well-modulated brakes, especially with towing a 3,500-lb. load. We enjoyed using Sport mode for carving corners, as it brings elongated shifts from the six-speed automatic; a crisp response comes when sport shifting in “manual mode” and provides a quick throttle response.

We tried out the Off-Road mode on a course that included flat and uneven dirt roads, as well as hill climb and descent. Although there is no downhill descent control system, the brakes worked well, along with manual gearing. Of note, Mazda would be wide to add downhill descent engineering for steeper and slicker terrain. We were able to test the difference between Normal and Off-Road over a special section of the course with sandy corners and a winding track at a speed of 30 mph showing the improved traction in the Off-Road programming and the aid of Mazda’s G-Vectoring Control that brings a bit of magic to transfer torque to the wheels where it is needed to keep the intended track-think of it like an enhanced traction control program that helps with steering and yaw control.

Other aids for off-road and backcountry travel are: the i-Activ All-Wheel Drive system that is standard equipment on all CX-50s, with a 50/50ish power transfer front to back; 8.6 inches of ground clearance; an 18-degree approach angle and a 24-degree departure angle; and an optional 360-degree camera system.

*EPA reports: base motor fuel economy 24 city/30 highway mpg, while the turbo option gets 23/29 mpg and can run on regular or premium fuel.
