The data indicates that all observed vehicles of the Mercedes-Benz A-Class (2012-16) A200 5-door hatchback with the specified description are equipped with a 1.6-liter engine capacity, and this engine capacity is present in 100% of the sample. Additionally, the primary fuel for these vehicles is petrol, which also accounts for 100% of the sample. This suggests that this model consistently comes with a 1.6L petrol engine, reflecting perhaps a standardized engine option for this particular version.
