Innovative Zoe demonstrates that an electric future needn’t be earnest, or range limited

What is it?

Renault’s electric charge will be spearheaded by the Zoe Z.E. model. A Clio-sized supermini – powered by electricity alone – the Zoe Z.E. will reach UK showrooms in Spring 2012.

This Zoe Preview model is the very same concept car that was shown at the 2010 Paris motor show, although its creator, Axel Breun, Renault’s Director of Show Cars and Concept Cars, admits that it’s 90 per cent representative of the production Zoe Z.E. that will silently be rolling out of Renault’s Flins plant in France this time next year.

What's it like?

Without proper firewall soundproofing, this Zoe Preview is uncharacteristically noisy for an electric car on the road. That 90 per cent figure quoted by Breun clearly relates to the car’s styling, rather than the actual engineering underpinning the Renault. The whining noise from the front-mounted motor and the direct drive reducer transmission is ever present, and it manages to grow in intensity as the speed rises.

Even as a concept, however, the performance on offer feels brisk enough, and the regenerative effect when lifting off is smooth rather than severe. Renault quotes an 8.1sec 0-62mph time and top speed of 84mph. Plenty for those Parisian side streets, the potential range of 100 miles is also unlikely to be too little for its intended urban role.

The steering, unassisted on the Preview concept, will be electric on the final production car, although despite its heft it’s accurate on the move. The suspension is more or less nonexistent, with the Zoe Preview feeling busy on tarmac that wouldn’t even trouble the Renaultsport Mégane Cup.

The production car will ride more sweetly, with it expected to feature Clio-derived MacPherson-type front suspension and torsion beam, coil spring rear set-up. Hard semi-slick had-cut Michelin show-car tyres don’t help the ride either. The tyre firm has used specific production rubber with the emphasis on providing low rolling resistance for maximum economy.

Renault’s first fully developed electric-only platform will underpin the Zoe. The French firm claims the platform is exclusively for its own use. The batteries come from a joint Nissan-Renault programme though, and thanks to that EV-specific platform they are positioned as low down in the car as is possible.

That ideal weight distribution should help the production Zoe ride and handle better than this skittish, poorly suspended show car. Input on the dynamics from Renaultsport is possible, indeed, Breun doesn’t rule out an entire Zoe Renaultsport version of the car, with Renault’s more focused wing playing a key role in the development of the Zoe’s Twizy Z.E. sister vehicle.

Understandably, the production car will lose this Preview’s more overt interior styling and gain a simple bench seat in the rear, but the digital displays will remain, with the bold central screen containing all the information regarding the condition of the battery. Breun admits too that despite the low current draw of the show car’s LED lights the production car will feature conventional headlamps. Likewise, the glass roof will go, as to retain it would only cause additional energy pull to control the climate inside.

Back to top

Should I buy one?

Cut through the show-car glitz and the Zoe’s conventionality is its biggest draw. Back that with good looks and the promise of an enjoyable drive and it could change the way we look at and use our superminis. It’ll be priced conventionally too, after the Government stumps up its £5000 subsidy the Zoe will be around the same price as a diesel Clio.

A brave new electric world, which you won’t need to be too brave to take the plunge into.

Re: Renault Zoe

I am not sold nor will I ever be sold (or buy) an all electric car - even if it is stunning to look at and actually does what it says on the box - which as we all know is NOT going to be the case. Why? Because the cost for running these is going to outstrip a conventional car for starters. You see Renault are working with urban and city government to set up charges/battery exchanges etc. The cost of this alone is going to pump up the price by 15-20%. But what really bothers me - are the so called GREEN credentials. The lithinium has to be mined - brought thousands of miles first one way and then the oether fron raw to operational status. Then you need electricity to charge it. And how is that electricity generated? 60/68% by petroluem, so where do those green credentials belong - in the sewer! Add to this - we are going to face a giant problem with the disposal of dead batteries - another source of heavy pollutant.

Give me the hydrogen car any day - and it will be BMW who beat Honda to doing it properly, and I reckon they will have mastered the storage problem within three years - worth waiting for!

Re: Renault Zoe

I remember seeing something on TV about a year ago on a small firm in wales making thin light flexible & cheap solar panel strips, no idea on power outputs but if it's cheap enough and can contribute to the charging then why not.

As for the car, despite claiming it's a "Renault only" platform, I can't see how they'll be able to keep it away from Nissan, or see any financial reason why they would want to.

One question though and this isn't just solely aimed at this car but at all electrically motivated cars, why do none of the manufacturers fit a solar cell roof? I know this would increase cost and weight a little but surely the benefits in warmer countries (and who knows, sometimes during the summer in the UK!) would more than compensate.

Because they're heavy, expensive and barely produce enough electricity to run an LED, let alone recharge a battery. Until photovoltiacs improve and become cheaper, lighter and with greater energy density there would be no point. Also warmth has nothing to do with it ;)

Lol, yes, I am aware warmth has nothing to do with it.

Here's my theory - a very rough one at that.

Check out the product below. This is a relatively cheap and crude (compared to the more advanced stuff out there) panel. Sadly, no weight is shown but I have sold these before and if memory serves me right, it isn't that heavy and certainly if you were going to produce a roof panel out of then, not much heavier than a glass equivalent.

Now, Hughseynight has commented that covering the roof would produce about 300w and take 70 hours to charge the battery. The Zoe has a range of 100 miles. I am no where near an electrical or an electronics expert but assume that the battery uses it's charge linearly. We can therefore assume that if I were to cover, say, ten miles (a commute to work for instance) then the using the panels would take 7 hours to re-charge the battery (assuming it was fully charged when I left).

If I do an 8 hour work day and the car is parked outside, this would mean I would not need to plug the car in to charge it at all and at the end of the day the battery would be fully charged again.

I am not sure what percentage of urban commuters would do a journey within those parameters but I'd imagine it's quite a few.

I realise my limited understanding of battery and electronics means this could be shot down in flames on a technical basis but the concept makes sense.
