Most Ford Fiesta models are fairly cheap to insure, but if you're looking for the lowest insurance costs then you'll want to look for models with lower-powered engines. This includes the likes of the 1.25-litre 'Studio' variant (2008 to 2017) and the 1.1-litre 'Style' variant (2016 to 2023) which reside in insurance groups 3 and 2 respectively.
