Focus 1.6TDCI 110, not just for the economy but because this is the nicest all-purpose Focus engine. It's best on 15" steel wheels with Michelin 195/65 R15 tyres, so shrugs off speed humps (see video test at hjuk that shows this) and also handles surprisingly decently on the taller rubber. But you do need to set the steering feel to 'sport'. The new model Renault Megane has best in class steering feel and suspension compliance, but handling is not quite as good as a Focus.
