Showcase of advanced technologies

The EOLAB prototype is a major engineering feat in automotive innovation. It is built on a B-segment vehicle platform and integrates around a hundred engineering innovations as well as achieving enormously low fuel consumption of one litre per one hundred km (for a CO2 emission of just twenty two g per km on an NEDC* combined cycle).

* Consommations et émissions homologuées selon réglementation applicable

To achieve this degree of fuel economy, our engineers focused on three main points:

EOLAB weighs around four hundred kg less than an ordinary B-segment vehicle. Excess weight was rigorously trimmed down across the entire vehicle: bod, drivechain, equipment, etc. The multi-material bod combines steel, aluminium and a magnesium roof that weighs just Four.Five kg. Much lighter weight means that much less fuel is needed to stir the car, and that vehicle subsystems (engines, batteries, brakes, etc.) can be made smaller; lightweight design is very much a virtuous circle. The cost savings achieved by downsizing the car’s mechanical subsystems were used to finance high-performance materials (aluminium, magnesium) with no increase in overall cost. The idea was to produce a prototype that suggested advanced technologies within an economically realistic production script.

Good attention was paid to streamlining the EOLAB assets outline, and aerodynamic spectacle is further improved by moving parts such as the side flaps, which act as fins. The better the aerodynamics, the better the fuel economy.

– ZE Hybrid technology

Renault’s innovative ZE Hybrid rechargeable technology, which combines a petrol engine with an electrified motor in a compact vehicle format, gives sixty km of distance under true zero-emission** conditions (like an electrical vehicle).

** Ni CO2 ni autres émissions polluantes réglementées pendant les phases de conduite.

A peek of the Renaults to come

True to Renault’s stance on affordable technologies, feasibility was a key factor across the EOLAB project. So as well as extreme fuel economy, the concept car would also have to suggest the sort of all-round spectacle that customers request, as regards convenience, roadholding, interior space, perceived quality and styling.

The development treatment was therefore technically and economically realistic. EOLAB would have to suggest spectacle comparable to that of a modern vehicle, as well as showcasing advanced technologies capable of carrying over to volume production in the years to come.

EOLAB addresses one of the projects in the French government’s Nouvelle France Industrielle plan on renewable energy resources, namely the two thousand twenty deadline on affordable vehicles with fuel consumption down to two litres per one hundred km.

With this prototype, Renault is testing out some of the technologies capable of meeting this ambitious aim.

EOLAB Concept: a wish car

Renault designers worked palm in mitt with our engineers to breathe life into the EOLAB concept car, styled to exude the virtues of lightweight, streamlined design. Just a duo of weeks now, and you’ll be able to see it for yourself in real life at the Renault stand at the Paris Motor Display in October!
