I'm a big fan of the 1.0 Ecoboost. Lighter, more frugal and torquier than a 1.6 litre NA engine, tiny, for flexible packaging, and makes a great noise as well. Brilliant little thing, in my opinion.
The engine's reputation for poor durability is unfair in my view. It only ever really had one issue, which was with a poor choice of material for one of the coolant pipes (known as the 'degas pipe'. The fact that the resulting coolant leak went on to cause major failure of the engine in many cases is unfortunate, but the fault itself is with a relatively cheap, and easily replaced external component, and is easily rectified. The base engine itself is strong, and has been successfully tuned to around 170 bhp without issue.
