The CrossBlue features a plug-in hybrid powertrain that combines a TDI engine with two electric motors, a DSG transmission, and an electric all-wheel-drive system dubbed 'propshaft by wire', and offers economy of 2.1 litres per 100 kilometres, or 134.5 mpg (Volkswagen's manufacturer estimated fuel economy rating in US gallons is 89 mpg combined in electric mode and 35 mpg as a hybrid).
