Renault Fluence electric plan

... that already includes Mitsubishi, Nissan, BMW and Mercedes-Benz.

Renault is taking a shortcut by converting its four-door Fluence sedan, already on sale in Australia with a petrol engine, to electric power and expects to add extra models as they become available from France.

But there is a big twist - Fluence Z.E. buyers will only pay Renault for the car and will then sign a contract with the Better Place organisation for their battery and energy supplies.

Renault promises the car will cost much the same as a petrol version of the Fluence, which would mean less than $30,000, but no-one is talking yet about the other costs or the exact rollout of the charging points and battery-swap locations that Better Place said will eliminate the 'range anxiety' that hangs over the future of electric cars.

"Our vision is clear. The overall cost of ownership must be equivalent to an internal-combustion car," said Justin Hocevar, managing director of Renault Australia. "Sales of the Fluence Z.E. will begin before the end of 2012."

The Renault move comes less than a week after Mitsubishi set the price of its very basic iMiEV plug-in car at $48,800 and following the commitment by its global Nissan-Renault alliance partner, Nissan of Japan, to a dedicated electric car called the Leaf.

The Nissan, too, is expected in Australian showrooms next year. Renault and Better Place are short on any real detail beyond the basics of the Fluence E.V. and a commitment to a national rollout of charging infrastructure that will start soon in Canberra.

"I'm very confident that the vast majority of electric car drivers will be able to drive wherever they want and whenever they want," says Evan Thornley of Better Place. He said that long-term supply deals for renewable energy, starting in Canberra, mean that electric car drivers will have more certainty on their long-term running costs than drivers of petrol-powered cars that face the uncertainties of oil company pricing.
