2014 – RENAULT EOLAB CONCEPT

2014 – RENAULT EOLAB CONCEPT

Renault revealed Eolab, a technology showcase that announces consumption of 100 km / l of CO2 emissions of 22 g / km. This hybrid gasoline study anticipates a hybrid production model which is expected to be launched in about a decade. The French brand justifies these values ​​by reducing weight (by using lighter materials such as aluminum and magnesium - representing a reduction of 400 kg compared to the average for B-segment cars), aerodynamics (by introducing among others, an active spoiler and side flaps that activate as ailerons) and the debut of ZE Hybrid technology (a new hybrid rechargeable solution that ensures low consumption and allows to travel in 100% electric mode on routes less than 60 km speed up to 120 km / h). According to Renault, the Eolab concept is an essay that prepares technologies to put into practice by 2020 a car capable of consumption of 50 km / l. This objective corresponds, in turn, to the challenge launched by the French government under the Nouvelle France Industrielle plan.

EOLAB A PROTOTYPE THAT MAKES 100 KM WITH ONLY 1 LITER OF GASOLINE

Renault presents the EOLAB, a prototype that explores the way of the very low consumption, making 100 km with only 1 liter of gasoline, with 22 g of CO2 emissions / km in NEDC * mixed cycle. In order to achieve this level of economy, the development team worked simultaneously on three fronts: weight reduction, aerodynamics and the totally unprecedented "ZE Hybrid" technology, which enables zero-emission running on daily routes. A true showcase of Renault's innovation for the environment, the EOLAB includes numerous technological advances that will be found progressively in the range vehicles. Pioneer of "zero emission" mobility ** with its range of electric vehicles, thanks to the new EOLAB Renault materializes the ambition to be one step ahead in reducing the environmental footprint of its vehicles at nissan altima car covers.

*  Consumption and emissions approved according to applicable regulations. ** Neither CO2 nor other emissions of regulated pollutants during the driving phases. Technologies to bring the very low consumption within the reach of all. With the launch of EOLAB, Renault remains faithful to its DNA, in order to bring the very low consumption to reach the largest number of people.

This feat means offering technologies at an affordable cost. EOLAB combines ultra-light materials such as aluminum or magnesium, incorporating from the beginning of the project the possibility of producing this type of vehicle on a large scale within a period of 10 years.

A hundred technological advances for future Renault

EOLAB is much more than a style exercise or showcase: conceived on the basis of a B-segment hatch, the prototype includes approximately 100 technologically advanced, technologically advanced technologies that will be progressively integrated into the future vehicles of the range.

The EOLAB recipe

Making 100 km with just 1 liter, the EOLAB prototype is the result of the combination of three ingredients: aerodynamics, weight reduction, petrol-electric 'ZE Hybrid' technology:

- aerodynamics: silhouette designed to penetrate the air and mobile components , such as an active spoiler and side flaps that move like airfoils;

- weight reduction: reduction of 400 kg in weight compared to a B-segment vehicle, thanks mainly to a body made up of multiple materials including steel, aluminum and composite materials, as well as a surprising magnesium roof of only 4 kg. This weight reduction is a virtuous circle, allowing to reduce the size and cost of the prototype systems (engine, battery, wheels, brakes, etc.) and compensate for the choice of more expensive materials.

- ZE Hybrid technology: compact and affordable, this new rechargeable hybrid solution has very low consumption and, above all, "zero emission" mobility ** on routes of less than 60 km and a speed of up to 120 km / h. ZE Hybrid technology will complement Renault's "zero emission" electric line ** in the coming years.

Contribution to the 'New French Industrial' plan

EOLAB is part of the project 'vehicle that consumes 2 liters / 100 km for all' launched under the 'New France Industrial' plan by 2020. But with the EOLAB prototype, Renault goes beyond goal set by the government in positioning its research project in a longer time horizon. In designing this prototype, Renault prepares the necessary technologies to launch a car capable of consuming less than 2 liters / 100 km in 2020. To achieve this, Renault has worked on a logic of collaborative innovation with partners of the French automobile industry , such as Saint-Gobain for the windows, Faurecia for the seats, Michelin for the tires and Continental for the braking system. Renault has also counted on other major partners, such as Posco, mainly for magnesium components. Thanks to their specific know-how, the partners were able, each with their expertise, to make a precious contribution to the feat performed by Renault with the EOLAB prototype.

*  Consumption, emissions and electric autonomy homologated according to applicable regulations. ** Neither CO2 nor other emissions of regulated pollutants during the driving phases. 

EOLAB Concept: a concept car for dreaming 

The designers leaned on the cradle of EOLAB to value their style. They created a concept car named EOLAB Concept, which will be presented at the Renault stand during the Paris Motor Show next October. This concept car derived from the prototype goes a step further in the design of the lines and attention to detail, referring even more to the notions of aerodynamics and lightness. With its lowered roof and a striking rear, the EOLAB Concept features a fluid and  aerodynamic style. Combining design and technologies, seduction and efficiency, Renault demonstrates that a dash of dream and magic can allude to the efficiency requirements of a vehicle prototype very low consumption.

EOLAB is part of Renault's eco2 environmental strategy

With the EOLAB, Renault materializes its desire to be one step ahead in reducing the environmental footprint of its vehicles, responding to the challenge of bringing the extremely low consumption to reach the largest number of people. Taking publicly the commitment to reduce its carbon footprint by 10% between 2010 and 2013 and, in achieving this goal, the Renault group innovates in the automotive industry. Renault is a leader in reducing the CO2 emissions of its vehicles in use, which are responsible for approximately 85% of its total carbon footprint. With its range of 100% electric vehicles and its increasingly economical vehicles, the Renault group, pioneer of mobility "zero emission" **; in 2013 showed the lowest level of CO2 emissions of all car manufacturers in Europe (less than 115 g CO2 / km) *.

* Average of the CO2 emissions of the Renault Group's car registration in 2013 in a range of 23 EU countries (All countries except Cyprus, Malta, Romania and Bulgaria). Data from the AAA DATA (Auxiliary Association of the Automobile Industry), subsidiary of the CCFA. AAA DATA is an association that manages the data of the automotive sector for the public authorities. 

** Neither CO2 nor other emissions of regulated pollutants during the driving phases. Renault transposes a new stage in its eco2 environmental strategy when presenting the EOLAB prototype, aiming to put the very low consumption to reach the largest number of people, by bringing together in a prototype a set of technological advances developed in a realistic strategy both technical as well as economical.

Always further away from reducing the environmental footprint

It materializes Renault's environmental strategy and its commitment to continue seeking to reduce the environmental footprint of these vehicles. It brings together approximately 100 technological resources that will be progressively integrated into the range of future products. In addition to Renault's commitment to the environment, this strategy will answer:

1. Regulatory objectives in the different countries and the commitment made by the Group to reduce its global carbon footprint (10% reduction between 2013 and 2016),

2. The expectations of customers in terms of savings and reduction of costs of use, in a context of tension regarding the availability and price of resources,

3. the expectations of public authorities and users regarding air quality in cities. The thermal range has evolved considerably in about 10 years in terms of consumption. The progressive application of technological resources relating to materials and vehicle architecture (aerodynamics, weight reduction, etc.) will further reduce energy demand. Increasing powertrain (GMP) electrification is both a symbol of performance in terms of consumption and an opportunity to reduce CO2 emissions from vehicle use. It will progressively increase the share of renewable energy and the overall energy efficiency of the well. The EOLAB "GMP" system benefited from the know-how acquired thanks to the development of the Group's electric range, which is still without equivalent. The technology chosen for this project is innovative in that it allows no-emission driving of the exhaust system on urban routes, and then move to thermal mode to follow your journey if necessary. As for all Renault projects, the challenge lies mainly in the development of an accessible solution for the largest number of people, being able to be deployed en masse, an indispensable condition for a significant and relevant impact on the environment.

The countries' energy availability and different usage profiles lead the automakers to expand their product lines and diversify them according to local markets. Under the Renault-Nissan Alliance, the Renault Group has the desire to continue to be the leader in electric vehicles in all its markets. The rechargeable hybrid solution presented in the EOLAB proposal is complementary to the range of electric vehicles and will be extended to different and multipurpose tread profiles, while maintaining the requirement for significant autonomy in 'zero emission' mode *.

* Neither CO2 nor other emissions of regulated pollutants during the driving phases. 

Breakthrough innovations to stay one step ahead 

Without breakthrough technological innovations, the environmental footprint can only decrease in the pace of fleet renewal by thermal vehicles that progressively respect the environment more, at a pace often associated with regulatory changes in pollutant emissions. That is why Renault is out of the question by proposing breakthrough technological innovations and accessible to all. Firstly, with 100% electric vehicles that emit neither CO2 or other compounds from the exhaust system, nor smell and engine noise while driving. Renault is the only automaker to offer a complete range with 4 electric vehicles. With the EOLAB project, Renault expands "zero emission" mobility * by exploiting an innovative hybridization solution called ZE Hybrid, which enables 100% "zero emission" mobility * for routes of less than 60 km ** and up to 120 km / h.

Zero Emission ** Emission Response: Effective Response to Air Quality Problem

According to a scientific modeling of the atmospheric environment based on data from the city of Rome, achieving a percentage of 20% zero emission vehicles in the central transit area significantly reduces the concentration of pollutants harmful to health . In the more polluted streets, the calculation shows a decrease that reaches up to 30% for particles that cause respiratory or cardiovascular pathologies, and up to 45% for NO2, a potent respiratory system irritant. The ZE Hybrid solution proposed by Renault is, along with the ZE range of 4 electric vehicles, a new and effective response to this public health challenge. A scientific study carried out by the company ARIA Technologies, a European leader in atmospheric modeling, and its Italian subsidiary ARIANET, in collaboration with the City of Rome and the Regional Agency for the Protection of the Environment of Latium.

* Neither CO2 nor other emissions of regulated pollutants during the driving phases. ** Consumption, emissions and electric autonomy homologated according to applicable regulations. Reduced weight by 400 kg, improved aerodynamics by 30%, ZE Hybrid technology  The record consumption achieved by the EOLAB prototype is based on three inseparable pillars: - particularly well-developed aerodynamics, improved by 30%; - reduction of the mass of the vehicle by approximately 400 kg in relation to a Clio IV type B hatch; - "ZE Hybrid" rechargeable chain, which benefits from the first 2 pillars and prefigures hybridization solutions for vehicles in the range.

PERFORMED AERODYNAMICS WITH ACTIVE ELEMENTS 

Aerodynamics: -30% SCx

EOLAB has a SCx of 0.470 m2 (S = 2.00 m2 and Cx = 0.235), that is, an overall gain of 0.200 m2, corresponding to an improvement of approximately 30% in relation to one Clio IV. This improved trawling leads to a very significant reduction in high-speed consumption: at a steady speed of 130 km / h, this represents  a reduction of 1.2 liters/ 100 km compared to the reference vehicle. 

EOLAB: Optimized Aerodynamics

1- Lowering of the roof

2- Narrowing of the rear

3- Living corners at the rear

4- Side-by-side mirroring

5- Aerodynamic air curtains

6- Narrow profile tires

7- Mobile front spoiler

8- Mobile suspension

9- Aerodynamically active hoods

10- Mobile rear flaps

11- Bottom of the fairing body

This exceptional aerodynamic performance is based on the combination of several components:

- Breaking architecture: this innovative choice allowed to reduce the rear gauge and lower the roof at the same time which maintains habitability;

- design of rear body forms particularly well cared for;

- active systems, to be a step further in the quest for aerodynamics.

Important: The indicator that characterizes the overall aerodynamic performance of a vehicle is the SCx, ie the front surface in m2 of the vehicle (S), multiplied by its air penetration coefficient, the famous Cx. Clio IV presents an SCx of 0.670 m2, which puts it at a good average in its segment. However, even so, it is not about gaining SCx at the expense of design and other attributes such as habitability.
