A turbo will needs additional cooling wich will cause additional drag, But a well set up turbo could delever superior FE. there is a curent trent among carmakers to make small turbochared engines to replace powerful big blocks, as these engines have the same power but much better FE and despite the addition of the turbo often weight less, than a big block.

Fiat is working on a turbocharged 2cylinder wich could deliver over 100Hp
