"It's a complex piece of engineering but best of all it works, and it works well"

A 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 extremely low fuel consumption of 1 litre per 100 km (for a CO2 emission of just 22 g per km on an NEDC* combined cycle).

* Consumption and emissions certified to applicable regulations

Lightweight design

EOLAB weighs around 400kg less than an ordinary B-segment vehicle. Excess weight was rigorously trimmed down across the whole vehicle: body, drivechain, equipment, etc. The multi-material body combines steel, aluminium and a magnesium roof that weighs just 4.5 kg. Much lighter weight means that much less fuel is needed to move 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 offered advanced technologies within an economically realistic production scenario.


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

Z.E. Hybrid technology

Renault's innovative ZE Hybrid rechargeable technology, which combines a petrol engine with an electric motor in a compact vehicle format, providing 60km of distance with zero-emission** conditions (like an electric vehicle).

** CO2 or other emissions regulated during phases of testing.
