Clean technologies

A clean car for all

The tightening of European regulations on CO2 emissions, together with the growing importance of environmental concerns, has made the clean vehicle one of the key focuses in the Group’s innovation strategy. Groupe PSA is a pioneer in the field and today stands as the European leader, with 102.4 g/km of CO2 emitted per vehicle on average, compared with a market average of 118.2 g/km.

Cleaner internal-combustion engines

A pioneer in the reduction of the environmental impact of its vehicles, Groupe PSA  prepared ahead of time for pollution standards and as early as the 1990s launched more environment-respectful engines. In 2016, 42% of the vehicles sold by the Group emitted less than 100 g/km of CO2.

  • The Group is at the root of major innovations in diesel engines:

    • The diesel particulate filter (DPF), launched back in 2000, is the most efficient solution in the automotive industry today. The most recent, the additive particulate filter, eliminates 99.9% of the particulates emitted by a diesel engine. In 2015, 91% of the diesel cars sold worldwide by Groupe PSA were equipped with a DPF.
    • The Blue HDi exhaust line, implemented gradually since late 2013 on the Group’s diesel engines, comprises selective catalytic reduction (SCR) technology that eliminates up to 90% of nitrogen oxide (NOx). Positioned upstream from the DPF, SCR technology also serves to reduce CO2 emissions by 4%. The Blue HDi exhaust line is now fitted on all the Euro 6 diesel engines on the European passenger cars produced by Groupe PSA.
  • In less than ten years, the Group will have renewed its entire range of petrol engines:

    The EB PureTech 3-cylinder petrol engine reduces CO2 emissions by an average 18% compared with the normally-aspirated 4-cylinder engines it replaces. The development of this high-performance and innovative technology involved the filing of 52 patents. The EB Turbo PureTech 3-cylinder petrol engine won Best Engine of the Year in its category (1.0 l to 1.4 l) in 2015, 2016 and 2017.

  • 18%

    reduction in CO2 emissions with the new family of EB PureTech 3-cylinder petrol engines developed by the PSA Group

From hybrids to electric cars

Reducing the environmental impact of cars also means inventing clean mobility solutions adapted to diverse uses and the budgets of each individual. The technologies developed by the Group reflect the maturity of its research into the issue.

Hybrid: a variety of options

  • Stop & Start and e-HDi: Stop & Start technology automatically stops and starts the engine, for a reduction of CO2 emissions in the city of up to 15%. It has been rolled out on practically all the ranges in Europe and over 20% in China.
  • Hybrid4: the first hybrid electric-diesel engine in the world, this technology is a real disruptive development in fuel consumption with a 30% reduction and CO2 emissions of under 100 g/km.
  • Plug-in petrol hybrid: a rechargeable hybrid drivetrain combined with a petrol engine set to make its debut on C and D segment models in 2019. Seven plug-in petrol hybrids will be marketed by 2021. This drivetrain will lead to a considerable reduction in fuel consumption (40%) and feature the best hybridisation elements:
    • SUV and CUV models with high-performance electric 4WD
    • a range of 60 km in electric mode
    • generous and uncompromising cabin space (passengers and boot)

Electric vehicle 

A pioneer in electric vehicles, the Group has sold 18,700 electric passenger cars and light commercial vehicles worldwide since 2010. Among the tests led by the Group, several projects are contributing to a gradual increase in the use of electric cars, notably in urban areas.

  • Since September 2015, the Group has produced the Bluesummer as part of a strategic cooperation agreement with Bolloré.
  • In spring 2016, Citroën launched the E-MEHARI, a 4-seater electric cabriolet with a range of 200 km.
  • PSA is also designing an electric version of the Common Modular Platform (CMP) developed in partnership with Dongfeng Motors for city cars, core-range hatchbacks and compact SUVs. The electric version of the CMP, co-financed by the two parties, will lead to a new generation of versatile and spacious electric vehicles with a range of up to 450 km and ultra-rapid charging solutions providing up to 12 km of range per minute of charging. Four electric versions will be launched between 2019 and 2021.
  • The VéLV may well revolutionise urban mobility. The easy-handling three-wheeler electric concept car has a top speed of 110 km/h and a range of 100 km.

Rethinking design, architecture and equipment

In addition to engine, hybrid and electric technologies, it is by optimising the entire design and all the characteristics of its vehicles that Groupe PSA has assumed leadership status in clean cars.

  • Reducing vehicle weight: the combination of new processes, techniques and materials has reduced vehicle weight by over 100 kg compared with previous-generation vehicles. For example, the Citroën C4 Cactus weighs 200 kg less than a Citroën C4.
  • Energy management: the use of low-energy-consumption technologies for air conditioning and lighting.
  • Eco-design: Groupe PSA is committed to limiting the environmental impact of its vehicles from design to end of life. As such, the Group has committed to integrating 30% of recycled or bio-sourced materials in the production of its vehicles. The recovery rate of Groupe PSA vehicles now stands at 95% (2015), of which 85% are reused or recycled.
