HDi and BlueHDi engines
Classic HDi diesel engines have been used in Peugeot models since the 2000s, while BlueHDi is the newer generation (from 2014) with SCR technology and AdBlue dosing to reduce nitrogen oxide emissions. The most widespread are the 1.5 BlueHDi (100/130 HP) and 1.6 BlueHDi (120 HP), used in the 208, 308, 2008 and 3008 models. The larger 2.0 BlueHDi (150/180 HP) powers the 508 and 5008.
