The Peugeot Diesel Range has never been so green!

How clean are Peugeot's latest diesel engines?

Every diesel engine in the 2017 Peugeot range is of a Euro 6 standard, this means they are the cleanest and safest ever. These engines will not face charges anywhere in Britain under the Government’s Clean Air Zone proposals. In recent months, older Diesel cars have come under scrutiny from the UK Government (and mainstream press) for the level of harmful emissions that they produce. The Society of Motor Manufacturers & Traders (SMMT) are campaigning to ensure that the differences between the varying compliance standards of used diesel cars are clear. This will help to ensure that customers are better informed about which cars comply with the latest emissions standards, and are therefore cleaner than their predecessors. Peugeot is in full support of the objectives of the SMMT to raise awareness and differentiate between older Diesel models and the newer, cleaner models. With all current Diesel Peugeot being Euro 6 compliant, no new Diesel Peugeot customer will be penalised for their choice of powertrain. We are confident that for many customers, diesel remains the best proposition.

What is a Euro 6 engine?

Euro 6 is the sixth incarnation of the European Union directive to reduce harmful pollutants from vehicle exhausts. The standard was introduced in September 2015, and all mass-produced cars sold from this date must meet these emission requirements. The aim of Euro 6 is to reduce harmful exhaust emissions, including nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons (THC and NMHC) and particulate matter (PM), which is basically soot from diesel cars. Reducing these pollutants can also mean improved fuel economy and lower CO2 emissions. As you can see from the table below, diesel engines have come a long way in the last 15+ years, Euro6 engines produce just 80mg of NOx, comparing to 500mg back in 2001.

Euro Standard

Date Effective Carbon Monoxide (g/km) NOx (g/km) Particulate Matter (g/lm)
Euro 1 Dec 1992 2.72 - 0.14
Euro 2 Jan 1997 1.0 - 0.08
Euro 3 Jan 2001 0.66 0.50 0.05
Euro 4 Jan 2006 0.5 0.25 0.025
Euro 5a Jan 2011 0.5 0.180 0.005
Euro 6 Sept 2015 0.5 0.080 0.005

Peugeots BlueHDi 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 duel economy of up to 91mpg with co2 as low as 82 g/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.
