New petrol-electric hybrid concept car previews a B-segment hybrid that's set to arrive within ten years
2 October 2014

Renault has revealed its new Eolab concept car, a petrol-electric hybrid which is claimed to average 282mpg and emit just 22/gkm of CO2.

The model, which made its public debut at the Paris motor show, acts as a preview to a new production B-segment model which will appear "within 10 years", according to Renault. It also answers a challenge set by the French government to put a car capable of returning 141mpg into production by 2020. 

The French manufacturer says that in order to reach its frugal economy target, its engineers concentrated on reducing the concept’s weight, refining its aerodynamics and getting the best performance from its petrol-electric powertrain.

The results mean the concept weighs 955kg, about 400kg less than the current Renault Clio. It also comes with a drag coefficient of 0.235, some 30 per cent less than the Clio.

Other weight-saving elements include a new bonnet that is fixed and therefore lighter because it doesn't need any latching mechanism, a thinner windscreen and a magnesium roof that weighs 4.5kg.

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.

Our Verdict

Renault Clio
Distinctive styling details are taken from the showstopping Renault Dezir concept car

A multi-talented contender that can stand comparison with the best

16 September 2014

Very impressive. So I guess this is what a Twingo will look like in 10 years (I know it's Megane-sized, but the way successive models increase in size these days ... ). Joking aside, when all cars have emissions this low, I wonder what ruse the politicians will come up with to tax/ban them from cities? It couldn't be on pollution grounds.

16 September 2014

The styling? I am a big fan of the current Clio and Twingo - but this is horrible! In my opinion anyway...
Also the name - at first glance I thought it said Ebola!

Technology asides there is some very impressive detailing and could form the design language for the next Clio and Twingo.

16 September 2014

Can't help feeling that bits of this are the new Megane...

16 September 2014

but since seeing the ridiculous claimed EDC figures of VW XL1, it goes without saying that to find out the real life figures, these cars have to be subjected to the US EPA tests to find out their real life MPG or MPGE in case of plug-ins. No wonder VW steered clear.

17 September 2014

It's not the method I'd have chosen but that's the way the government has dictated that hybrid's MPG figures have to be published. Hopefully other manufacturers will follow Mitsubishi's lead and provide MPG when the battery is empty & electric-only range as well.

18 September 2014

I don't think this is a good direction for Renault to travel down, based on the styling. To me it screams far, far too much Toyota, particularly the rear quarters. It's as if Renault are in an identity crisis again. The Twingo, Clio and Captur have all shown relative consistency; this takes things a step too far in my opinion.

Eolab is an anagram of Ebola.

I am just saying that's all.
