EXCLUSIVE: Detailed Photos of 2017 Chevrolet Colorado ZR2 SuspensionPosted in News on September 21, 2016
Thanks to the bold photo work from our friends at SpiedBilde, we’ve got the first detailed suspension photos of the 2017 Chevrolet Colorado ZR2, giving us new insights on the first Bow Tie off-road special since the 1994-2003 S-10 ZR2.
Foremost, the suspension shots showcase a widened track and revised suspension geometry, designed to provide additional wheel travel and higher off-road performance compared to the standard Colorado pickup. The shocks are Multimatic DSSV units, which will likely feature spool valves to provide unique compression and rebound rates for improved wheel control. DSSV, which stands for “dynamic suspension spool valve,” has been used to great effect in road cars like the late, lamented 2015 Chevrolet Camaro Z/28.
According to GM Authority, the Z/28’s shocks provided four-way adjustment, allowing compression and rebound tuning at high- and low-speed shock events. Such racecar technology may seem a bit out of place on an off-road pickup, but the use of the DSSV system might actually make a lot of sense on the ZR2, giving it precise wheel control on both wide-open desert terrain and tight, tricky backwoods trails.
In addition to DSSV, the Colorado’s shocks also feature piggyback reservoirs for greater fluid capacity, helping improve performance by resisting shock fade. DSSV also precludes the need for progressive dampening, at least in theory. Curiously, the Colorado’s jounce bumpers persist in the ZR2, at least on this prototype. We certainly hope that changes for the production model, as it limits upward control arm travel.
Perhaps mitigating those jounce bumpers will be the ZR2’s wider front and rear track. The revised track width will allow the wheels greater travel without needing reengineer the standard Colorado’s suspension hard-points, helping preserve the Colorado’s stability. While the rear leaf springs are something of a mystery in terms of specifications and supplier, the massive front coil springs come from German supplier Mubea, as specified on the tag. Although single-rate coils, they’re impressively thick, so we expect high spring rates up front.
Other goodies include tires that look like they'll be good at legitimate off-road work. A fullsize spare can be seen hanging behind the wider rear axle, and rugged rock sliders should provide a little bash protection against crags and boulders. Furthermore, this Colorado is probably sporting refreshed sheetmetal up front, a feature that should hit all Colorados for the 2018 model year. What will be reserved for the ZR2 will be the bold front and rear fender flares, sized to accommodate the truck's wider track on both axles.
And finally, although the original Colorado ZR2 concept truck from the 2014 Los Angeles Auto Show was powered by the then-new 2.8L Duramax I-4, each of the test mules seen previously had gassers under the hood. However, the photographer said this truck was equipped with a DEF tank, giving us newfound hope that GM will offer a diesel in the ZR2. The prospect of an oil-burning off-roader has us salivating profusely.
Now, we turn the magnifying glass over to you, reader. What clues can you deduce from our spy photographer’s impressively detailed shots? Let us know in the comments!
