  1. Last year at the SEMA Show, Chevrolet teamed up with American Expedition Vehicles (AEV) to produce the Colorado ZR2 AEV concept. This truck was fully kitted out for overlanding duties with a revamped suspension, new bumpers and skid plates, a snorkel, Warn winch, bed rack, and an air compressor. It seems Chevrolet is planning to make this into a production model. Off-Road.com learned from a Chevrolet dealer that GM at their annual dealer meeting showed off a model called the Colorado ZR2 Bison. “The AEV truck they revealed looked nearly identical to the concept vehicle with some minor differences,” the unnamed dealer said in email. The differences are most likely the absence of the bed rack and air compressor from the concept. What would likely carry over are the larger fenders, meaty off-road tires, upgraded suspension, and underbody protection. The dealer also said that the Bison will be available at dealers soon according to Chevrolet officials at the meeting. Source: Off-Road.com View full article

  3. If you're a truck manufacturer and have decided to build an off-road special, sooner or later you will be entering it a desert race to prove its merit. Ford and Toyota have done it with their respective models, and soon Chevrolet will be joining this crowd with the Colorado ZR2. The truck seen here was developed and built by Hall Racing. Competing in the Best in the Desert’s General Tire “Vegas to Reno” (the longest off-road race in the U.S), the Colorado ZR2 will be in class 7300, reserved for stock mid-size trucks and SUVs. 'Stock' carries a different meaning in racing as the ZR2 has some modifications for the race such as a rollcage, racing seats and harnesses; 44-gallon fuel tank, and additional lighting. Otherwise, most of the mechanical bits such as the 3.6L V6, eight-speed automatic, front and rear locking differentials, and the stock wheels. The Multimatic spool valve shocks have been tweaked, but Chevrolet doesn't mention how. The truck will also be acting as test bed for possible new parts for the ZR2 and regular Colorado from Chevrolet Performance. Source: Chevrolet Press Release is on Page 2 COLORADO ZR2 MAKES COMPETITION DEBUT IN AMERICA’S LONGEST OFF-ROAD RACE Hall Racing to compete in stock-class with ZR2 in Best in the Desert Racing series LAS VEGAS — Chad Hall of Hall Racing will debut a modified 2017 production Chevrolet Colorado ZR2 during Best in the Desert’s General Tire “Vegas to Reno” race presented by FOX. “Vegas to Reno,” known as “the longest off-road race in the United States,” begins at 9:30 a.m. on Friday in Las Vegas and ends at various times on Saturday morning, August 19, in Reno, Nevada. More than 350 contestants are expected to participate this year’s 550-mile race. The course encompasses a wide array of grueling terrain, from silty desert wallows, to dry lake beds and mountain passes as high as 8,000 ft. above sea level. Entered in class 7300, which comprises stock production mid-sized pick-ups and SUVs, Hall Racing’s modifications to their ZR2 include sanctioning body-mandated safety items such as a roll cage, a 44-gallon racing fuel tank and racing seats with safety harnesses. KC HiLites racing lights, two-way radios and a GPS system have also been added. The truck retains the stock ZR2’s 3.6L V-6 engine and eight-speed automatic transmission, along with a modified version of ZR2’s Multimatic DSSVTM damper technology. In addition to Hall Racing’s alterations, this crew cab ZR2 acts a testbed for Chevy Performance and hints at a range of potential parts to be offered for ZR2 as well as the standard Colorado. “The components being tested on this truck are ultimately intended to take the already-exceptional off-road capability of the Colorado to the next level,” said Russ O’Blenes, director, Performance Variants, Parts and Motorsports for General Motors. “Racing them allows us to quickly understand their performance attributes and reliability in the extreme environment of off-road racing, ensuring the highest performing components for Colorado customers.” Hall Racing, the winningest family of off-road racers in the legendary Baja 1000, has a long history of racing with General Motors production-based vehicles in both Best in the Desert and SCORE desert series. “The Colorado ZR2 is one of the most capable production platforms we’ve used as a foundation for our racing program,” said Chad Hall. “The base Colorado is strong and robust with the expected advantages of a midsize package. ZR2 adds great technology, like the Multimatic DSSVTM dampers and the front and rear locking differentials that are vital to stock class desert racing.” The 2018 Colorado ZR2 is effectively a segment of one, combining the nimbleness and maneuverability of a midsize pickup with a host of new off-road features and the most off-road technology of any vehicle in its segment. Compared to a standard Colorado, the ZR2 features front and rear tracks that have been widened by 3.5 inches and a suspension lifted by two inches. Functional rockers have been added for better performance over rocks and obstacles, and the front and rear bumpers have been modified for better off-road clearance. Class-exclusive features include standard front and rear electronic locking differentials, available diesel engine and the first off-road application of Multimatic Dynamic Suspensions Spool Valve (DSSVTM) damper technology. As with all Chevrolet trucks, the Colorado ZR2 is built with durability in mind, including a fully boxed frame, roll-formed high-strength steel bed and Duralife brake rotors. View full article

  5. It was three years ago that Chevrolet showed off the Colorado ZR2 concept at the LA Auto Show. It was a mean looker with an aggressive look, raised suspension, and meaty off-road tires. Imagine our surprise when Chevrolet revealed the production version tonight in Los Angeles. The 2017 Colorado ZR2 keeps the mean look of the concept with a new front end treatment, raised hood, skid plates, 31-inch Goodyear Duratrac tires mounted on 17-inch wheels, and an optional spare tire carrier in the bed. But under the skin is where the juicy changes are. Chevrolet has widened the track by 3.5-inches, raised the suspension by 2-inches and equipped it with unique spool-valve dampers from Multimatic - yes the same folks who are being tasked with building the upcoming Ford GT. The dampers first used on the Camaro Z/28, come with six different tuning curves up front, and four in the rear to provide better ride and handling characteristics over different terrains. Engine choices include the 3.6L V6 (308 horsepower, 275 pound-feet) and 2.8L Duramax Turbodiesel (181 horsepower, 369 pound-feet). The four-wheel drive system features a set of electronic-locking differentials for the front and rear axles. No word on pricing on when the Colorado ZR2 will arrive at dealers. Source: Chevrolet Press Release is on Page 2 New Colorado ZR2 A "Segment of One" Among Off-Road Pickups New performance variant of the Chevrolet Colorado excels in tight two-tracks, technical rock-crawling, fast desert running and on pavement LOS ANGELES — Just as introduction of the Chevrolet Colorado reset the bar for mid-size trucks, the new Colorado ZR2 is poised to reset expectations for off-road trucks. Chevy’s new performance halo for the Colorado lineup will feature more off-road technology than any other mid-size pickup when it goes on sale. The ZR2 is effectively a segment of one, combining the nimbleness and maneuverability of a mid-size pickup with a host of new off-road features and the most off-road technology of any vehicle in its segment. Compared to a standard Colorado, the ZR2 features a much wider track and a lifted suspension. Functional rockers have been added for better performance over rocks and obstacles, and the front and rear bumpers have been modified for better off-road clearance. Class-exclusive features include front and rear electronic locking differentials, available diesel engine, and the first off-road application of Multimatic Dynamic Suspensions Spool Valve (DSSVTM) damper technology. As a result, the Colorado ZR2 delivers exceptional performance in a variety of scenarios – from technical rock crawling to tight two-track trails to high-speed desert running to daily driving. “Our engineers have been incredibly successful developing Corvette and Camaro performance variants with broad performance envelopes,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “The ZR2 applies that same philosophy to off-road performance. You can go rock crawling on Saturday, desert running on Sunday, and comfortably drive to work on Monday. This truck can do it all, and do it all well.” First off-road application of Multimatic DSSV dampers To achieve this unprecedented balance of on- and off-road performance, the Chevy engineering team turned to a surprising partner in creating the ZR2’s dampers, which are the heart of any off-road truck. Multimatic Inc., based in Markham, Ontario, is a renowned maker of high-performance Dynamic Suspensions Spool Valve (DSSV) dampers as used in championship-winning motorsport vehicles, including recent Formula One winners. The first volume production vehicle to use DSSV dampers was the 2014 Chevrolet Camaro Z/28. The 2017 Chevrolet Colorado ZR2 will be the first application of Multimatic DSSV damper technology to an off-road vehicle. “From our experience on Z/28, we knew the performance advantages offered by DSSV dampers, “ said Mark Dickens, executive director, Performance Variants, Performance Parts and Motorsports Engineering, Chevrolet. “We also know that Multimatic’s motorsport development mentality would allow us to bring a uniquely precise and repeatable custom damper to market even more quickly than a traditional damper system.” Compared to deflected-disk valving common on most dampers, the ZR2 employs spool valves that offer increased precision and manufacturing repeatability along with enhanced ride and handling performance both on- and off-road. The Colorado ZR2’s DSSV dampers are position-sensitive. Their aluminum bodies each house two spool valves providing both compression and rebound damping optimized for everyday driving. During extreme off-road use, a third, piston-mounted spool valve delivers additional, uniquely tuned, compression damping. The front dampers also employ a separate rebound valve, which comes into play when the suspension approaches full extension. “A traditional, deflected-disc damper only offers two force-velocity curves for tuning,” Dickens said. “The ZR2 dampers offer six tuning curves for the front, four at the rear. For the driver, this translates to greater confidence and control in a wider range of driving experiences.” Design meets mud, sand and rock Visually, the production version of the Colorado ZR2 closely resembles the concept shown at the 2014 Los Angeles Auto Show. Consumer response to that concept was so overwhelming, the team knew they needed to carry as much of the original design into production as possible. “For both the concept and the production versions of ZR2, the exterior design was shaped by the desire to improve capability driving over mud, sand and rock,” said Rich Scheer, director of design for Chevrolet Truck. “The wider, more aggressive stance, modified front and rear bumpers, and even the bed-mounted, spare-tire carrier all improve performance driving over rough terrain.” Compared to a Colorado Z71, the ZR2 has a more aggressive side profile, with the suspension lifted two inches for greater ground clearance. The steel-tube, functional rocker protectors will be standard equipment on the ZR2, and are strong enough to protect the body side while dragging the truck against a rock face. The ZR2 also features 17 x 8 inch aluminum wheels, in a pattern exclusive to the ZR2, wrapped in 31-inch Goodyear Duratrac off-road tires for exceptional traction. The front and rear track has been widened by three-and-a-half inches, with new cast-iron control arms for greater durability in off-road situations. As a result, the ZR2 offers greater wheel travel and stability while traversing steep grades. The front bumper of the ZR2 has tapered ends, to increase the tire clearance when approaching obstacles. The bumper also integrates a thick, aluminum skid plate protecting the radiator and engine oil pan, while the transfer case is protected by an additional shield. Above the bumper, the ZR2 features a more aggressive grille and hood – with black insert – to complement the other exterior changes. A bed-mounted spare tire carrier, seen on reveal vehicles at the Los Angeles Auto Show, will be available as an accessory. “The bed-mounted spare tire adds a rugged look to ZR2, and serves a functional purpose. By relocating the spare to the bed, ZR2’s departure is improved and prevents any damage to the spare when you’re crawling over obstacles,” said Scheer. Class-exclusive electronic lockers, available diesel engine The ZR2 also features the most sophisticated four-wheel drive system in the segment. With class-exclusive, electronic-locking differentials front and rear and Chevrolet’s AutoTrac transfer case, the ZR2 offers nine drive configurations: 2WD 2WD, locked rear differential Auto 4WD Auto 4WD, locked rear differential 4WD Hi, locked transfer case 4WD Hi, locked transfer case and locked rear differential 4WD Lo, locked transfer case 4WD Lo, locked transfer case and locked rear differential 4WD Lo, locked transfer case, locked front and rear differentials Extensive work was done to integrate the electronic lockers and allow them to seamlessly interact with the traction control, stability control, and hill-descent control. In addition, a new “Off-Road Mode” button, in combination with the traction control switch, allows the anti-lock brakes, traction control, and stability control calibrations to be tailored to different driving conditions. Off-road Mode also alters the throttle progression and shifts calibrations to give the driver better control and responsiveness. The ZR2 shares its powertrains with the 2017 Colorado, and it will be the only extreme production off-road truck to offer the choice of gas or diesel engines. The all-new 3.6L V-6, mated to a class-exclusive Hydra-Matic 8L45 8-speed automatic transmission, yields 308 horsepower and 275 lb-ft of torque, while the class-exclusive Duramax diesel engine produces 181 horsepower and 369 lb-ft of torque and will provide excellent range to overland drivers. Even with all of the off-roading upgrades over the base truck, the ZR2 can still tow up to 5,000 lbs. – enough to pull a camper, trailer dirt bikes, jet skis, snow mobiles and other toys – or carry 1,100 lbs. of payload. As such, the Colorado ZR2 offers a distinct position in the market: Compared to other midsize trucks, the Colorado offers an unrivaled suite of powertrain technologies; compared to full-size off-road trucks, the ZR2 is about a foot narrower and 500 pounds lighter, enabling greater agility over obstacles and better trail access. “It’s amazing what a difference a foot of width makes off road,” said Dickens. “The smaller size of the Colorado is a huge enabler for taking the ZR2 more places, and getting it through tighter spots than you could access with a full-size truck.” New, off-road development track at GM’s Yuma Proving Ground For the development of the Colorado ZR2, Chevrolet developed new off-road test areas at General Motors’ Yuma, Arizona Proving Ground. The Yuma Proving Ground is located on 2,400 acres of land in southeastern Arizona. Opened in 2009, Yuma features a range of tracks, laboratories and courses. The new off-road facility features a multitude of off-road simulations, including high-speed desert sand trails; low-speed, loose river rock crossings; and steep, technical hill climbs and descents. Yuma Proving Ground’s new off-road course allowed the team to test multiple iterations of components on the ZR2 is a single day. These components were then tested a real-world facilities like Moab, Johnson Valley, and Rubicon to ensure the ZR2 is trail-ready right from the factory. View full article

As such, the Colorado ZR2 offers a distinct position in the market: Compared to other midsize trucks, the Colorado offers an unrivaled suite of powertrain technologies; compared to full-size off-road trucks, the ZR2 is about a foot narrower and 500 pounds lighter, enabling greater agility over obstacles and better trail access. “It’s amazing what a difference a foot of width makes off road,” said Dickens. “The smaller size of the Colorado is a huge enabler for taking the ZR2 more places, and getting it through tighter spots than you could access with a full-size truck.” New, off-road development track at GM’s Yuma Proving Ground For the development of the Colorado ZR2, Chevrolet developed new off-road test areas at General Motors’ Yuma, Arizona Proving Ground. The Yuma Proving Ground is located on 2,400 acres of land in southeastern Arizona. Opened in 2009, Yuma features a range of tracks, laboratories and courses. The new off-road facility features a multitude of off-road simulations, including high-speed desert sand trails; low-speed, loose river rock crossings; and steep, technical hill climbs and descents. Yuma Proving Ground’s new off-road course allowed the team to test multiple iterations of components on the ZR2 is a single day. These components were then tested a real-world facilities like Moab, Johnson Valley, and Rubicon to ensure the ZR2 is trail-ready right from the factory.
  7. A couple of years ago, Chevrolet rolled out the Colorado ZR2 concept. This truck showed what a possible off-road focused model could look like. At the time, Chevrolet said this was only a concept. But some new spy shots show GM is considering putting this model into production. While the front end is camouflaged very well, we can make out certain details such as a new front bumper, tow hooks, and a skid plate. The bumper is an important change as the current one limits how far you can off-road. The suspension has been lifted (an inch or two we're guessing) and there is a set of meaty off-road tires. Engines choices are likely to be the 3.6L V6 and 2.8L Duramax four-cylinder turbodiesel. In terms of off-road hardware, we wouldn't be surprised if there are new differentials, shocks, and possibly some assist systems such as hill descent control. No word on we could see this model. With next Tacoma TRD Pro just around the corner, the midsize truck class is only getting more interesting. Source: Autoblog, AutoGuide View full article

  9. Last month, speculation was going around after an trademark application was filed by GM for 'Badlands' to be used on a future model. The speculation was this was going to be used on the Chevrolet Silverado and GMC Sierra as competitors to the Ford Raptor. But according to Edmunds, GM has no plans for a direct Raptor competitor. "We have a lot of priorities. Capital is not endless. That is not one of our highest priorities in terms of spending capital right now," said Mark Reuss, GM's executive vice president of global product development. However, Reuss isn't fully against a performance off-road monster. He points toward the Chevrolet Colorado ZR2 concept shown at LA Auto Show which boasts a number of changes such as off-road shocks, front-and-rear locking differentials, and 35-inch off-road tires "We showed the ZR2 and said we would like to do that," said Reuss.
