The Nissan Diesel Range has never been so clean and efficient

How clean are Nissan's latest diesel engines?

Every diesel engine in the 2017 Nissan 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. Nissan 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 Nissan being Euro 6 compliant, no new Diesel Nissan 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/km
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 5 Jan 2011 0.5 0.180 0.005
Euro 6 Sept 2015 0.5 0.080 0.005

Nissan Diesel engines

Nissan diesel engines are designed to consume less fuel and produce fewer emissions. The tech focuses on energy loss reduction in the power train and reduction of excessive energy use during idling. It also incorporates an energy retention aspect to recover any wasted energy. To accomplish its goals for reduced CO2 emission, Nissan has developed a number of systems that fine-tune each Nissan model’s performance.Nissan diesel engines are designed to consume less fuel and produce fewer emissions.
