Renault Eolab Concept Debuts at Paris with 1.0 L/100km Target
Renault has revealed the Eolab Concept at the 2014 Paris Motor Show, showcasing a 1.0-litre hybrid powertrain, advanced aerodynamics and lightweight construction aimed at ultra-low fuel consumption.
Renault has unveiled the Eolab Concept at the 2014 Paris Motor Show, outlining a technical showcase for future ultra-efficient production cars. The three-door hatch, based on the Clio platform, targets a combined fuel consumption of just 1.0 litre per 100km, using a lightweight structure and a petrol-electric hybrid drivetrain.
The Eolab’s weight is 400kg less than a standard Clio, achieved with a multi-material body shell combining aluminium, magnesium and composite panels. The roof is magnesium, the glass is ultra-thin, and the interior is pared back to cut further mass. Renault has also fitted active aerodynamic elements, including a front spoiler and rear flaps, plus active suspension to lower the ride height at speed. The result is a drag coefficient of just 0.235.
Hybrid powertrain and performance
Power comes from a 1.0-litre three-cylinder petrol engine producing 75hp and 95Nm, paired with a clutchless three-speed transmission and an integrated electric motor. The electric motor delivers 68hp and 200Nm, drawing energy from a 6.7kWh battery. Renault claims an all-electric range of up to 60km, with the hybrid system designed for maximum efficiency in urban and mixed driving.

Aerodynamics and materials focus
Renault’s use of active aero and composite materials puts the Eolab among the most advanced concept cars at the show. The magnesium roof and aluminium panels are not common in this segment, and the active suspension system is configured to lower the car at speed, reducing drag and rolling resistance. The Eolab’s ultra-thin windscreen glass and lightweight interior trim are further examples of the lengths Renault has gone to in pursuit of efficiency.
Production intent and context
Renault has presented the Eolab as a technology demonstrator rather than a direct preview of a production car. The company says many of the lightweight and aerodynamic solutions could reach future B-segment models, as manufacturers face tightening emissions rules and customer demand for lower running costs. The Eolab’s hybrid system and weight-saving measures indicate Renault’s direction for future efficiency gains across its small car range.
The Eolab appears alongside other advanced concepts at the Paris Motor Show, including the Toyota C-HR and the Lamborghini Asterion Hybrid, reflecting the industry’s focus on hybridisation and efficiency.
