There is not a lot of information about the Chevrolet Colorado ZR2 model right now. The last we saw it was when Chevrolet showed off the concept a few years ago. Since then, there have been a few spy images here and there but nothing from the side of Chevrolet.
Most people are just happy that Chevrolet is actually going to turn it into a production model but others want to know what Chevrolet is fitting under the hood first before they decide if it is worth waiting for or not.
Based on the latest set of spy images, it looks like the Chevrolet Colorado ZR2 will be coming in with a gasoline engine as it was spotted while it was getting fueled up at a gas station.
Of course, this does not mean that a diesel engine will not be offered as they could still be offering the Colorado ZR2 with a few engine options. The new Chevrolet Colorado ZR1 will be coming in to compete with the Toyota Tacoma TRD Pro and is expected to make its debut this fall.
