Power plants are more efficient than engines crammed within the trunk of a car. They have no limitations in space and weight and so you can do fancy things like heat recovery (you use the exhaust to pre-heat your fuel mix or reuse said heat for nearby industries), always have the combustion chamber at the best temperature for efficiency, ... . Plus, you can install much better filtration systems for combustion byprod…
We should definitely take what improvements we can get!
