Didn't the GM in line 5 and 6 they used in the previous Colorado/Trail blazer get poor milage? What motor do they use now in the new Colorado?
The 5 and 6 cylinder were in the GM Atlas family. There is also a 4 cylinder member of the Atlas family. It is a 2.9 liter, 4 valve per cylinder, like it's bigger brethren the 5 (3.7 liter) and 4.2 liter, 6 cylinder Atlas engines.
The MPG wasn't bad in the 5 cylinder (my son had one), power was good for the time and this engine series won some engineering awards. My son's 5 cylinder Atlas was reliable and durable. He had his for 6 years, put 130K on it, not an issue.
The 2.9 Atlas 4 cylinder is still available as the base engine in the Colorado/Canyon.
The other engines available in these trucks are the 305 hp, 3.6 liter DOHC, 4 valve per cylinder gas V6 and the 2.8 liter, turbo 4 cylinder diesel.
