LOS ANGELES (Wednesday, Nov 16, 2016) – Just as introduction of a Chevrolet Colorado reset a bar for mid-size trucks, a new Colorado ZR2 is staid to reset expectations for off-road trucks. Chevy’s new opening halo for a Colorado lineup will underline some-more off-road record than any other mid-size pickup when it goes on sale.

The ZR2 is effectively a shred of one, mixing a liveliness and maneuverability of a mid-size pickup with a horde of new off-road comforts and a many off-road record of any automobile in a segment.

Compared to a customary Colorado, a ZR2 comforts a many wider lane and a carried suspension. Functional rockers have been combined for softened opening over rocks and obstacles, and a front and back bumpers have been mutated for softened off-road clearance.

Class-exclusive comforts embody front and back electronic locking differentials, accessible diesel engine, and a initial off-road focus of Multimatic Dynamic Suspensions Spool Valve (DSSVTM) check technology.

As a result, a Colorado ZR2 delivers well-developed opening in a accumulation of scenarios – from technical stone crawling to parsimonious two-track trails to high-speed dried using to daily driving.

“Our engineers have been impossibly successful building Corvette and Camaro opening variants with extended opening envelopes,” pronounced Mark Reuss, executive clamp president, Global Product Development, Purchasing and Supply Chain. “The ZR2 relates that same truth to off-road performance. You can go stone crawling on Saturday, dried using on Sunday, and absolutely expostulate to work on Monday. This lorry can do it all, and do it all well.”

First off-road focus of Multimatic DSSV dampers

To grasp this rare change of on- and off-road performance, a Chevy engineering group incited to a startling partner in formulating a ZR2’s dampers, that are a heart of any off-road truck.

Multimatic Inc., formed in Markham, Ontario, is a eminent builder of high-performance Dynamic Suspensions Spool Valve (DSSV) dampers as used in championship-winning motorsport vehicles, including new Formula One winners.

The initial volume prolongation automobile to use DSSV dampers was a 2014 Chevrolet Camaro Z/28. The 2017 Chevrolet Colorado ZR2 will be a initial focus of Multimatic DSSV check record to an off-road vehicle.

“From a knowledge on Z/28, we knew a opening advantages offering by DSSV dampers, “ pronounced Mark Dickens, executive director, Performance Variants, Performance Parts and Motorsports Engineering, Chevrolet. “We also know that Multimatic’s motorsport growth genius would concede us to move a singly accurate and repeatable tradition check to marketplace even some-more fast than a normal check system.”

Compared to deflected-disk valving common on many dampers, a ZR2 employs bobbin valves that offer increasing pointing and prolongation repeatability along with extended float and doing opening both on- and off-road.

The Colorado ZR2’s DSSV dampers are position-sensitive. Their aluminum bodies any residence dual bobbin valves providing both application and miscarry damping optimized for bland driving. During impassioned off-road use, a third, piston-mounted bobbin valve delivers additional, singly tuned, application damping. The front dampers also occupy a apart miscarry valve, that comes into play when a cessation approaches full extension.

“A traditional, deflected-disc check usually offers dual force-velocity curves for tuning,” Dickens said. “The ZR2 dampers offer 6 tuning curves for a front, 4 during a rear. For a driver, this translates to larger certainty and control in a wider operation of pushing experiences.”

Design meets mud, silt and rock

Visually, a prolongation chronicle of a Colorado ZR2 closely resembles a judgment shown during a 2014 Los Angeles Auto Show. Consumer response to that judgment was so overwhelming, a group knew they indispensable to lift as many of a strange settlement into prolongation as possible.

“For both a judgment and a prolongation versions of ZR2, a extraneous settlement was made by a enterprise to urge capability pushing over mud, silt and rock,” pronounced Rich Scheer, executive of settlement for Chevrolet Truck. “The wider, some-more assertive stance, mutated front and back bumpers, and even a accessible bed-mounted, spare-tire conduit all urge opening pushing over severe terrain.”

Compared to a Colorado Z71, a ZR2 has a some-more assertive side profile, with a cessation carried dual inches for larger belligerent clearance. The steel-tube, organic rocker protectors will be customary apparatus on a ZR2, and are clever adequate to strengthen a physique side while boring a lorry opposite a stone face.

The ZR2 also comforts 17 x 8 in. aluminum wheels, in a settlement disdainful to a ZR2, wrapped in 31-inch Goodyear Duratrac off-road tires for well-developed traction.  

The front and back lane has been widened by 90 mm (3.5 inches), with new cast-iron control arms for larger continuance in off-road situations. As a result, a ZR2 offers larger circle transport and fortitude while traversing high grades.

The front fender of a ZR2 has slim ends to boost a tire clearway when coming obstacles. The fender also integrates a thick, aluminum movement image safeguarding a radiator and engine oil pan, while a send box is stable by an additional shield. Above a bumper, a ZR2 comforts a some-more assertive grille and hood – with black insert – to element a other extraneous changes.

A bed-mounted gangling tire carrier, seen on exhibit vehicles during a Los Angeles Auto Show, will be accessible as an accessory. “The bed-mounted gangling tire adds a imperishable demeanour to ZR2, and serves a organic purpose. By relocating a gangling to a bed, ZR2’s depart is softened and prevents any repairs to a gangling when you’re crawling over obstacles,” pronounced Scheer.

Class-exclusive electronic lockers, accessible diesel engine

The ZR2 also comforts a many worldly four-wheel expostulate element in a segment. With class-exclusive, electronic-locking differentials front and back and Chevrolet’s AutoTrac send case, a ZR2 offers 9 expostulate configurations:

  • 2WD
  • 2WD, sealed back differential
  • Auto 4WD
  • Auto 4WD, sealed back differential
  • 4WD Hi, sealed send case
  • 4WD Hi, sealed send box and sealed back differential
  • 4WD Lo, sealed send case
  • 4WD Lo, sealed send box and sealed back differential
  • 4WD Lo, sealed send case, sealed front and back differentials

Extensive work was finished to confederate a electronic lockers and concede them to seamlessly correlate with a traction control, fortitude control, and hill-descent control. In addition, a new “Off-Road Mode” button, in mixed with a traction control switch, allows a anti-lock brakes, traction control, and fortitude control calibrations to be tailored to opposite pushing conditions. Off-road Mode also alters a stifle march and shifts calibrations to give a motorist softened control and responsiveness.

The ZR2 shares a powertrains with a 2017 Colorado, and it will be a usually impassioned prolongation off-road lorry to offer a choice of gas or diesel engines.

The all-new 3.6L V-6, corresponding to a class-exclusive Hydra-Matic 8L45 8-speed involuntary transmission, yields 308 horsepower and 275 lb-ft of torque, while a class-exclusive Duramax diesel engine produces 181 horsepower and 369 lb-ft of torque and will yield glorious operation to overland drivers.

Even with all of a off-roading upgrades over a bottom truck, a ZR2 can still draw adult to 2,268 kilograms (5,000 lbs.) – adequate to lift a camper, trailer mud bikes, jet skis, sleet mobiles and other toys – or lift 499 kilograms (1,100 lbs.) of payload.

As such, a Colorado ZR2 offers a graphic position in a market: Compared to other midsize trucks, a Colorado offers an unequaled apartment of powertrain technologies; compared to full-size off-road trucks, a ZR2 is about a feet narrower and 227 kilograms (500 lbs.) lighter, enabling larger lively over obstacles and softened route access.

“It’s extraordinary what a disproportion a feet of breadth creates off road,” pronounced Dickens. “The smaller distance of a Colorado is a outrageous enabler for holding a ZR2 some-more places, and removing it by tighter spots than we could entrance with a full-size truck.”

New, off-road growth lane during GM’s Yuma Proving Ground

For a growth of a Colorado ZR2, Chevrolet grown new off-road exam areas during 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 comforts a operation of tracks, laboratories and courses. 

The new off-road trickery comforts a crowd of off-road simulations, including high-speed dried silt trails; low-speed, lax stream stone crossings; and steep, technical mountain climbs and descents.

Yuma Proving Ground’s new off-road march authorised a group to exam mixed iterations of components on a ZR2 is a singular day. These components were afterwards tested a real-world comforts like Moab, Johnson Valley, and Rubicon to safeguard a ZR2 is trail-ready right from a factory.
