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 one of the European leaders, with 114.1 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 2018, 18% of the vehicles sold by the Group emitted less than 100 g/km of CO2.

At the end of 2015,  Groupe PSA undertook an unprecedented initiative to offer its customers better information on the consumption of its vehicles in real use.

Groupe PSA is the only manufacturer to have initiated a unique and scientific approach in order to guarantee reliable information to its customers. This initiative has been deployed in collaboration with two leading NGOs T&E, Transport and Environment, and FNE, France Nature Environnement –  committed to the environment and sustainable mobility and a certification body, Bureau Veritas.

The measurements were made within the framework of a protocol, robust and reproducible, validated by T&E and FNE. Bureau Veritas organization has checked and certified their compliance.

Inspired by the European Real Driving Emission (RDE) procedure, the protocol measures fuel consumption in real conditions on open roads thanks to a portable equipment installed on the vehicle (PEMS)

Since the end of 2015:

  • A team of 8 full-time staff dedicated to the development of the Protocol and the implementation of the measures
  • A budget of more than 1M €
  • 6 months of protocol development
  • More than 525 measurements made on nearly 70 models
  • 50,000 km traveled on open roads and 3,000 km on test benches.
  • The consumption values ​​of more than 1000 VP versions published on the brand’s website: Peugeot, Citroën and DS.
  • A configurator available on the brands websites to allow customers to estimate the consumption of their vehicle according to their uses.

8 February, 2018: The test protocol introduced by Groupe PSA to provide precise, accurate information to its Peugeot, Citroën and DS customers has just won Europe’s ECOBEST 2017  award for the relevance of its project.

  • 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 2018, for the 4th consecutive year

  • 99.9%

    of the particulates emitted by a diesel engine eliminated by Groupe PSA's additive particulate filter

  • 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.

  • 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.
