Chevrolet News:Chevrolet Colorado ZR2 Goes Off-Road Racing

Recommended Posts


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.

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.

AWESOME! :metal: 

I can see the R&D here being applied to many versions of trucks and SUV's including an EV off roader.

      If you're currently a Ford Mustang owner or lessee, until the end of October there is $3,000 waiting for you on the hood of any 2019 Chevrolet Camaro.  Chevy's Camaro has consistently ranked third in sales behind the Dodge Challenger and Ford Mustang ever since the 6th generation model debuted for 2016. Sales fell further in 2019 after a disastrous redesign of the front fascia on SS trim models, down 7.6% year to date.  This despite the greater availability of 4-cylinder models and packages that put the V8 in easier reach. 
      While the Camaro is down 7.6 percent, the Mustang has also fallen 10.1 percent and Challenger is down 11 percent year to date.  The Ford and the Dodge however sold 20,000 units and 10,000 units more respectively. 
      Camaro sales were just 50,963 in 2018, down from a 2011 high of 88,249, and are on pace to be much lower this year.

      Ahead of the 2019 SEMA show in Las Vegas, Chevrolet gave us a preview of the 2021 Chevrolet Colorado ZR2.  After the refresh, the Colorado will show greater differentiation from trim to trim.  All Colorados will feature embossed Chevrolet tailgates instead of the rear bowtie badge. The bowtie up front will be revised. 
      The WT, LT, and Z71 will get updated center bars, lower fascias, and front skid plates for 2021. The WT and LT get gold bowties while the Z71 gets a black one.  
      The ZR2 off-road variant gets a new look (shown above), and will be the only Colorado to get a lettered front fasica. 
      The ZR2 continues to get Multimatic DSSV Position senstitive dampers, standard front and rear locking differentials, 2-inch suspension lift, 3.5 inch wider track, off-road rocker protection, cast iron control arms, autotrac transfer case, multiple skid plates, and now standard red tow hooks. 
      Over 520,000 Colorado pickups have been built to date.
      The Colorado will continue to be built at GM's Wentzville Plant and the 2021 will go on sale midway through next year.
