2. It's pretty big
The Colorado is visually smaller than the Silverado, using more slopes and curves contrasting the larger truck’s hard lines, but in reality this midsize pickup isn’t much smaller than its big brother.
The longest Silverado, the crew cab standard box model, is 239.57 inches long in total length, compared to the Colorado’s 224.5 inches in crew cab long-box form. That makes this new truck just about 15 inches shorter in its longest form.
However, on the small end, the Silverado regular cab standard box is 205.57 inches long, while the Colorado crew cab model is 208.2 inches long, though in this case the Colorado offers a small backseat while the Silverado only has space for two captains chairs or a bench.
Height-wise, the new Colorado actually dwarfs the Silverado, with a total height of 78.9 inches (including the antenna) when fitted with four-wheel drive compared to the Silverado’s 73.80 inches in four-wheel drive trim. Though it may be taller, the Colorado is a full 5.7-inches skinnier than the Silverado.
So the new midsize truck is just a touch smaller than its big brother in most areas, though it is slightly larger than both the Tacoma and Frontier in almost all configurations.
