Without a doubt truck owners
Without a doubt truck owners that tow near the maximum loads these trucks can handle would do better with the top-rated truck, the Colorado Duramax 2.8L. Or a Silverado for that matter, if the owner can tolerate the extra size. True that the new Tacoma with its 42 added hp is only 3 mpg better than the outgoing model still for sale. However, you throw in that "After 10 years" part. Ten years ago the Tacoma V6 4x4 had a combined rating of 16 mpg manual and 17 mpg auto. The new truck's 23 mpg rating represents a 35% improvement in fuel economy over the 2006 and no V6 mid-size truck in the market has a higher fuel economy rating. Since you live in a southern state your Colorado will also have a great cost per mile because diesel is not used to heat homes in that area of the country, hence its price is not $1.00 more than unleaded gas like it is in many parts of the U.S. from October to May.
