Powering the concept is a hybrid power unit that comprises a 1.0-litre, three-cylinder SCe petrol engine, producing 74bhp and 70lb ft, and an electric motor, which is claimed to produce 54bhp and 148lb ft.
The permanent magnet electric motor is integrated into the housing of the car's compact three-speed transmission, which sends drive to the front wheels.
The first two speeds of the transmission are used only by the electric motor, with the third gear being driven by the internal combustion engine, and the automated control unit permits a blend of electric or hybrid outputs. Renault says this transmission offers numerous weight and cost-saving benefits compared to usual CVT or dual-clutch options.
A selectable ‘weekend’ mode allows the car to function as a conventional hybrid for greater range, with both power sources working together and the battery being charged via braking and deceleration.
The Eolab will be presented in two forms at the Paris show. One car will showcase the car’s technology and the other will be a design study. Renault says it has used “warm and sensual lines” to create the Eolab's exterior. The car sits on 19-inch carbon-aluminium wheels shod in Michelin rubber.
A series of active flaps and a front spoiler also open at speed, directing air flow and cooling the engine if necessary.
Inside, the three-door Eolab concept features four leather seats and a ‘floating’ centre console. An 11-inch touchscreen tablet, inspired by Renault’s production R-Link system, controls most infotainment functions and also provides real-time updates on how efficiently the car is being driven. Lights inside the car also change colour according to driving style.
A digital, height-adjustable instrument cluster sits in front of the driver. It features two smartphone-sized screens which display car data and navigation information. The car’s side mirrors are replaced by cameras, which feed directly into screens mounted close to the windscreen pillars.
The Eolab contains 100 new technology innovations, says Renault, which will eventually find their way into the firm’s road cars.
The project's leader, Jean-Pierre Fouquet, says the Eolab concept wouldn't be too costly to put into production: “Today, most of the market’s hybrid vehicles are upper-segment cars with a price tag of more than €40,000 (around £31,900).
“The solutions showcased by Eolab are much more economical and enable hybrid technology to be used for smaller cars and on a much bigger scale. Our objective is to produce a car with two power sources for the price of one".
Although Renault currently focuses on full electric vehicles in its production car range, it hasn't ruled out introducing hybrids. Renault boss Carlos Ghosn said: "The Eolab is the perfect illustration of how Renault is dedicated to still developing plug-in hybrid, hybrid, diesel powertrains and can still innovate, not just focus on making EVs. For us, it is not either/or – there is all sorts of technology we are still developing."
Any production version of the Eolab is likely to rival Peugeot’s Hybrid Air technology if it goes on sale. Peugeot’s 2008 Hybrid Air prototype is capable of returning 106mpg and CO2 emissions of 50g/km, although it is still at least three years away from production.
