Although technically not the result of hard work and stealth-mode surveillance from our spy shooters, we caught this modified 2017 Chevrolet Colorado ZR2 near the GM Proving Grounds in Milford, Mich. We've liked this custom setup from the first time we saw it as a chase vehicle during our mid-size pickup truck outside Gateway, Colo., earlier this year. We even did a quick walk-around video of the truck (or one similar to it) at the same event. Here's what our shooters sent us:
"This is what appears to be an additional prototype for the Chevrolet Colorado ZR2 extended-cab utility truck.
"We're guessing Chevrolet built a concept version of a ZR2 modified to be a utility truck earlier this year, probably to show it to various fleet buyers as a potential alternative to full-size pickups. But now a modified version of that truck has been spotted testing, suggesting it could be added to a ZR2-style truck with the addition of a snorkel, white LED Reverse lights, a revised rear bumper, a ZR2-badged tailgate and a different M plate, which are all seen on this truck.
"The test model features the raised ZR2 ride height, and more aggressive wheels and tires, plus a deep-water snorkel. Yet it continues with the utility truck's rear design that includes a modified bumper and side lock boxes.
"If it ever comes to production, expect one of us behind the wheel."
