I test drove a Colorado diesel last Saturday. Having never driven a new Colorado or Canyon before I was not surprised that it was light years ahead of the previous generation in ride, handling, interior quality and styling. The Colorado diesel I drove was a red CCLB 4x4 Z71 with 3.42 axle ratio. It was well equipped, but not loaded and had a price tag of $41,260 including $3905 for the 2.8L Duramax. The engine had good power and worked well with the 6 speed auto transmission but it will not wow you if you're running it like a gasser in the upper rpm range. The little 2.8L Duramax is more impressive in the low and mid rpm range where a diesel engine is suppose to work.
