A 90% reduction in CO2 eq. emissions: a challenge that became a reality with Renault Emblème
Renault Emblème demo car reflects a company's vision of a car meeting the challenge of low-carbon mobility.
Addressing a major engineering and innovation challenge, this concept shows how vehicle production can enable a company such as Renault Group to achieve net zero carbon[1] by 2040 in Europe and by 2050 worldwide.
Renault Emblème was developed to maximise decarbonisation throughout its life cycle. It is a family car designed to slash CO2 eq. emissions from cradle to grave by 90%, compared with an equivalent vehicle today.
This shooting brake of elegant, flowing lines symbolises a design intended to optimise aerodynamics and maximise efficiency.
Renault Emblème is driven by an all-electric powertrain powered by a dual power energy, designed to reduce carbon emissions without compromising on versatility. It comprises a 40 kWh battery for everyday use with a hydrogen fuel cell for longer journeys.
Emblème is 4.80 metres long, reaffirming Renault's ambition to continue innovating in the C segment and higher.
Emblème will be displayed on the Renault stand at the 2024 Paris Motor Show. In the near future, Ampere will be unveiling this concept in full, showing the technological advances making this level of decarbonisation possible.

A Renaulutionary approach to decarbonisation

Decarbonising mobility is a key objective in the fight against climate change. For an automotive

company such as Renault Group, it involves addressing a number of challenges relating to

industry, energy, technology, supply, speed, and so on. To achieve net zero carbon by 2040 in

Europe and 2050 worldwide, in line with its targets, the company needs to revolutionise the way

it designs and builds its vehicles.

This approach is demonstrated by Renault Emblème displayed by the brand on its stand at the

Paris Motor Show from 14 to 20 October. This vision of a family vehicle is a laboratory showcasing

the innovations developed by Renault, Ampere and their partners to meet these requirements.

The main challenge of this landmark project lies in the extent to which decarbonisation has been

maximised across the entire life cycle of the vehicle, from cradle to grave. Following on from the

Scenic Vision H2-Tech concept in 2022, Renault Emblème takes the approach one step further,

slashing greenhouse gas (CO2 eq.) emissions by 90%, compared with an equivalent vehicle built

today; to produce just 5 tonnes of CO2 eq. from cradle to grave (see methodology section at the

end of the press release).

To achieve this, the project explored a multitude of intelligent, credible and viable combinations:

recycled materials with a low carbon footprint, natural materials, production processes relying

entirely on renewable energy, general implementation of re-used parts and circularity, etc. The

same was true ofthe technical choices, including the powertrain.

Efficiency at the heart of Renault's new design language

Renault Emblème symbolises a new holistic approach to vehicle design. Its exterior design

blends sportiness, elegance and emotion through sensual curves and graphic, technical

character lines, creating an ultra-desirable object. The design is also the result of meticulous

optimisation of aerodynamics, designed for efficiency through a more sustainable approach

without compromising on aesthetics. On Renault Emblème, for example, the exterior rearview

mirror is replaced by two cameras integrated into the wheel arches, with windscreen wipers

concealed under the bonnet and e-latch handles recessed into the bodywork. Two fins on the

bonnet and two air vents on the bumper channel the airflow towards the windscreen and behind

the wheels, respectively. The wheels are full disc, in order to conduct the air flow along the body.

The F1-inspired flat-bottom design is enhanced by an active diffuser, which tilts downwards and

to the rear to balance the airflow and minimise aerodynamic drag.

The design was fine-tuned using digital twin technology and state-of-the-art digital simulation

equipment provided by the BWT Alpine F1 Team, as part of a fruitful collaboration between

Renault and Ampere. By pooling their expertise, they were able to optimise passive and active

aerodynamics for efficient air penetration. Renault Emblème has a very good Cx of 0.25.

The elegance of a family shooting brake making no compromises

on efficiency

Renault Emblème's strong curves and shooting brake style are showcased by the dichroic effect

of the green bodywork, making the colour look different depending on the angle from which it is

viewed. The vehicle is an elegant combination of an estate, with a wide wheelbase of 2.90

metres, and a coupé with a moderate height of 1.52 metres and flowing roofline.

The vehicle is 4.80 metres long, making it ideal for comfortable family travel, with passengers

and luggage. It also symbolises Renault's reaffirmed ambition to continue innovating in the C

segment and higher, in line with its value-based strategy. Exploring new paths in design inspired

by the iconic Renault logo, the light signature is intended to be both high-tech and easily

identifiable.

A vehicle’s weight, which is partially linked to its size, impacts its CO2 eq. emissions at several

levels: when materials are extracted, during production and transport, during use (impact on

energy consumption) and when the vehicle is recycled. As part of their eco-design approach,the

designers and engineers hunted down every superfluous kilogram, with the aim of reaching a

weight of 1,750 kg, including batteries. Renault Emblème therefore weighs less than most hybrid

SUVs or electric vehicles of similar size.

A powertrain combining versatility and low carbon performance

Renault Emblème has a dual power energy electric powertrain powered in two ways: by a

“conventional” rechargeable battery, sufficient for everyday use, and by a hydrogen fuel cellfor

longer journeys. Based on the AmpR Medium platform, the rear-wheel drive architecture hosts

the various powertrain components (electric motor, battery, fuel cell and hydrogen tank) while

maintaining a low centre of gravity and ideal weight distribution to promote performance and

efficiency.

Emblème 's 160 kW wound-rotor electric motor uses no rare earths. It is powered by a small NMC

battery (40 kWh), which is lighter, cheaper, less bulky and more environmentally friendly than

that of a long-range family electric vehicle. It has a range of several hundred kilometres, more

than enough for everyday journeys. The 30 kW PEMFC fuel cell runs on low-carbon hydrogen via

a 2.8 kg tank, providing the power required for long journeys, with maximum efficiency of around

60%.

This configuration maximises the versatility of this type of vehicle, which is able to cover a

distance of up to 1,000 km as rapidly as an ICE vehicle: without charging but with just two stops

for hydrogen refuelling – less than five minutes each time – for a range of 350 km. On a typical

journey between Paris and Marseille, 75% of the electricity consumed by the vehicle is produced

by the fuel cell, with no emissions other than water.

An innovative working method

In view of the ambitious decarbonisation goals, Emblème demo car required new working

methods. More than 20 partners, all experts in their own fields, worked on the project with

Renault and Ampere. Each one contributed their own technology or expertise to slash CO2 eq.

emissions by 90% over the vehicle's entire life cycle.

This collective horizontal approach encourages innovation without barriers between the Group,

its brands, entities, partners and suppliers. For this project, this approach made it possible to

harness exceptional technological diversity and complexity to achieve high decarbonisation

targets. The Emblème demo car shows once again that Renault Group is at the forefront of

innovation, driving progress in mobility and the automotive industry in general, making its entire

ecosystem part of the process.

Ampere will unveil this carin full at the end of October.

Via Renault.

Il frontale mi rimanda un po’ a quello delle Renault di inizio anni 2000

[Angus85]

Questo concept è un esercizio di stile, oppure prefigura un modello che arriverà in gamma Renault?

[nucarote]

Si ho pensato anch'io ai frontali delle Renault di fine anni '90.

Comunque spero che non manda già in soffitta il family feel inaugurato da Rafale.

[Indav]

Hanno cambiato family feeling per la seconda volta in tre anni?

[The Krieg]

Qui hanno fatto centro. Il design di Scenic era bello ma si sono accorti velocemente che era poco personale. Qui hanno corretto bene il tiro e hanno tirato fuori qualcosa di originale e estremamente caratteristico come Renault, in parte poi mi tornano alla mente Megane 1 e compagnia.

Io spero di sì, per quanto schizofrenico meglio correggere subito invece che perseverare

[nucarote]

IMHO quel family feel degli anni '90 non era proprio il massimo, si salvavano giusto Scenic e Laguna. Nel complesso questo concept mi sembra poco originale, una Cupra in salsa Renault.

[Rohypnol]

Ci vedo anche un po' di family feeling Lotus (Eletre) a dir la verità. 😅

 

Scherzi a parte, vedo un modello curioso e inaspettato da una Renault che spara idee a raffica, anche se per essere un modello "vision" è un po' troppo carica di linee contrastanti e con un posteriore da far incrociare gli occhi. Mi piacciono anche i cerchi, chiusi ma con personalità.

[MotorPassion]

Un ritorno agli stilemi anni '90 con un posteriore che ricorda Lotus Eletre/Emeya ed MG Cyberster. 

[KimKardashian]

A me pare na Cupra
