Eco-efficient technology: PureTech engine, BlueHDI, WLTP

Thanks to our eco-efficient technologies, our sustainable development approach aims to reduce greenhouse gas emissions, protect natural resources and develop new environmentally friendly mobility behaviors.

Electrification according to DS Automobiles

Designed for the world of tomorrow, E-TENSE embodies ultimate driving pleasure, maximum efficiency through energy regeneration and unhindered mobility regardless of future regulations. A world reference in electrics, E-TENSE technology is present on each of the new DS Automobiles electric models. It embodies our desire to become a 100% electric brand from 2024.

Building on our commitment and our title of double champion in Formula E, we have incorporated technologies from motorsport such as energy recovery during braking into our electric and plug-in hybrid models. Born from performance, our models open up new horizons for you, with style.

More compact, lighter, more powerful

PureTech gasoline engines allow you to control your consumption while boosting the performance of your DS vehicle.
Our engineers managed to achieve a significant reduction in fuel consumption by reducing the size and weight of our engines and integrating innovative low-friction materials.

By reducing the size and weight of our engines, and integrating innovative low-friction materials, our engineers have managed to achieve a significant reduction in fuel consumption and thus, CO₂ emissions per vehicle.

The alliance of efficiency & driving pleasure

BlueHDi technology designates our range of diesel engines which offer a latest generation depollution system.
Our 4-cylinder BlueHDi diesel engines are available in two different power ratings: 130 hp and 180 hp.

This system equips all our BlueHDi diesel engines to eliminate pollutants from diesel combustion: unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and fine particles.

Decontamination in 3 steps

STEP 1

The oxidation catalyst transforms unburned hydrocarbons (HC) and carbon monoxide (CO) into water (H2O) and carbon dioxide (CO₂).

2ND STEP

The SCR (Selective Catalytic Reduction) catalyst eliminates 90% of nitrogen oxides (NOx) by transforming them into water and nitrogen thanks to the addition of AdBlue®.

STEP 3

The Particle Filter (FAP) eliminates up to 99.9% of fine particles in number.

Efficient solutions

AdBlue®

AdBlue®, a mixture of water and urea, non-toxic and environmentally friendly, transforms 85% of polluting nitrogen oxides into water vapor and harmless nitrogen. To refill your AdBlue® tank, located in the trunk or next to the fuel flap, the procedure is identical to that of a full tank of fuel. By filling up with AdBlue®, you will benefit from 20,000 km of autonomy.

STOP & START

Sustainably control your fuel consumption and significantly reduce your CO₂ emissions thanks to Stop & Start technology. This function automatically puts your engine to sleep when your vehicle stops temporarily. You will reduce your fuel consumption in dense urban traffic by -15% on average, compared to a conventional vehicle.

Des consommations plus réalistes

The WLTP (Worldwide Harmonised Light vehicles Test Procedure) is the vehicle approval protocol within the European Union that specifies a new test cycle and procedure for measuring fuel consumption, CO2 and regulated pollutant emissions from light-duty vehicles Light-duty vehicles = passenger and light-duty commercial vehicles < = 3.5 tonnes under standardized (laboratory) conditions.

The WLTP protocol replaces the previous approval procedure (NEDC) which came into force in 1992. Since September 2017, all new models marketed for the first time are WLTP approved. Since September 2018, all vehicles sold must be WLTP approved. This new laboratory test protocol will be complemented by the real-world pollutant emission measurement: Real Driving Emission (RDE).

The new WLTP protocol will allow consumers to have a more accurate view of their vehicle’s fuel consumption and CO2 emissions.

DS Automobiles et le nouveau protocole WLTP

In terms of NOx emissions, DS Automobiles vehicles equipped with Euro 6.2 engines comply 3 years in advance with the conformity coefficient of 1.5 (RDE measurement – Real Driving Emission) required by the Euro 6d regulations of 2020.

Thanks to judicious technological choices deployed in anticipation of the regulations (SCR in diesel and GPF in gasoline), our vehicles are already WLTP approved (compulsory for all private vehicles from September 2018) which comes closer to the real use of clients.

The customer is at the heart of our concerns. This is why we have always supported the implementation of procedures representative of customer usage and why we strive to stay ahead of new protocols to stay at the technological forefront.
As proof of our transparency, we have published on our site the consumption of our models since 2016 and their NOx emissions since March 2018 in real conditions of use, according to a protocol developed with NGOs (T&E and FNE) and certified by a third party organization. independent (Bureau Veritas).

From NEDC to WLTP

The new WLTP procedure aims to ensure a better representativeness of the actual conditions of use of vehicles and their current technologies during approval. It defines stricter test conditions and a more dynamic driving profile than the previous NEDC cycle developed in the 1990s. Its construction was based on actual taxi data while the NEDC was based on theoretical driving profiles.

WLTP also produces more precise values because it takes into account the specifications of each vehicle including all of its optional equipment whose influence on fuel consumption and CO2 emissions can be noticeable. WLTP values are, in some cases, higher than NEDC values for the same car. This does not mean that the fuel consumption performance is degraded, it is simply a new measure based on a more rigorous, longer benchmark, thus better reflecting the current uses of vehicles.

NEDC VS WLTP

	NEDC	WLTP
test cycle	Cycle de test unique	Cycle dynamique plus représentatif des conditions de conduite réelle
Cycle time	20 minutes	30 minutes
Distance du cycle	11 kilomètres	23,25 kilomètres
Phases de conduite	2 phases, 66% de conduite urbaine et 34% de conduite rurale	4 phases plus dynamiques, 52 % de conduite urbaine et 48 % de conduite rurale
Vitesse moyenne	34 km/h	46,5 km/h
Vitesse maximum	120 km/h	131 km/h
Influence des options individuelles	Le NEDC ne tient pas compte de l’impact sur les émissions de CO2 et sur la performance énergétique	Les caractéristiques additionnelles (pouvant varier selon les modèles) sont prises en compte
Changements de vitesse	Changements de vitesse fixes	Points de passage calculés pour chaque véhicule
Températures de test	Mesures réalisées entre 20 et 30 °C	Essais réalisés à 23 °C, CO2 corrigé à 14 °C

Real Driving Emissions - RDE

From September 2018, in addition to the WLTP approval protocol, all manufacturers will have to measure the emissions of their real-driving vehicle (RDE) of all vehicles sold within the EU, and in Switzerland, Turkey, Norway, Liechtenstein, Israel and Ireland.

In these RDE tests, emissions of pollutants such as nitrogen oxides (NOx) and fine particulate matter are measured on open roads for more realistic information.
