Clean, powerful and efficient diesel engines

BlueHDi is the name given to Peugeot’s latest generation of fuel and environmentally efficient diesel engines.

Generated from a world-famous diesel heritage and innovative, automotive engineering excellence, BlueHDi complies with Euro 6 emission standards to deliver a driving experience rich in power and performance but with exceptional fuel economy and CO2 emissions.

BlueHDi engines meet Euro 6 standards thanks to Selective Catalytic Reduction (SCR) and Particle Filtration processes. BlueHDi delivers the cleanest diesel engine possible and exceptional fuel economy of up to 91mpg with CO2 as low as 82g/km.

A three stage cleansing process specifically targets the pollutants of diesel combustion, removing hydrocarbons and carbon monoxide, reducing nitrogen oxides by up to 90% and eliminating 99.9% of particulates:

  • Stage One - the oxidation catalytic converter eliminates the HC and the CO2, transforming them into water (H2O) and carbon dioxide (CO2)
  • Stage Two - the SCR (Selective Catalytic Reduction) transforms the nitrogen oxides (NOx) into water and nitrogen (N2), which is the main constituent of air (78%), due to the addition of AdBlue® (mixture of urea and water)
  • Stage Three - the Particulate Emission Filter eliminates 99.9% of the particulates by number


DIESEL PARTICULATE FILTER (FAP)At the end of the 90s, Peugeot identified the need to treat the fine particulates emitted by diesel engines to bring them down to the level of petrol engines and launched the Diesel Particulate Filter (FAP) -- a world first -- on the 607 in 2000. From 2007, Peugeot made FAP standard across its entire range.

A HDi diesel prototype racing car built by Peugeot Sport to compete in the 24 Hours of Le Mans. Unveiled in 2005, it was one of the only diesel engined sports cars of its time and took the Le Mans title in 2009. It won a total of 19 of its 28 races between 2007 and 2010.

Our BlueHDi technology was recognised in the 2015 Next Green Car Awards, with the Peugeot 208 1.6 BlueHDi Active 75 S&S being named 'Best Supermini'.

Our latest BlueHDi technology is available now on the models below and is being rolled out across the entire Peugeot range.
