In my opinion, the 4 cylinder engine that's in the newer Malibu's is to small for the size of the car, this making it under powered and poor fuel mileage. The 2023 Colorado's are all going to have a 2.7 4 banger, that power plant is way to small for the Colorado. GM is making the truck bigger and putting a toy motor in it. The inline 5 was a good engine, was good on gas had plenty of power and would run forever, this is why gm quit building it and the 3.1 V/6 as well.
