I am a Colorado fan( even a member of ) and always have been. But there is one thing that I have never understood. Why did GM not put the 4.2 I6 in the colorado when it came out in 2004, as it is little more then the truck version of the Trailblazer SUV? The 4.2 would have greatly improved the capabilty and both vehichles use basicly the same transmission( or exactly the same, I'm not sure ) So why did GM cut it down a cylinder and go with what is now the 3.7 5 cylinder? It doesn't make much sense to me. Can anybody else help me out?

So now I guess the question is why did GM decrease the size of the colorado from the size of the Trailblazer enough to where the 4.2 wouldn't fit? It and the Trailblazer do pretty close in fuel economy and the power would definitly be more with the 4.2 then with a cut down version
Because then there would be even less reasons to buy it because it would be almost the size of a full size truck and would probably get the same mileage with less hp and torqe than the 5.3.
