 These basic technologies represent the foundations of BlueMotion.Currently, they cover the TDI (turbocharged diesel direct injection) and TSI (boosted petrol stratified direct injection) engines as well as the extremely efficient Direct Shift Gearbox (DSG).They are supplemented by technological innovations that include drive variants such as EcoFuel (natural gas
engines), BiFuel (liquid natural gas engines), MultiFuel (ethanol engines), hybrid systems and electric drives, as well as NOx emissions control, regenerative braking and the Stop-Start system.
