A new study by international consultants Deloitte has found that fuel prices will need to reach beyond $2.60 per litre before most buyers will consider an electric vehicle.
The results also showed that a majority of motorists will stick with fossil fuels even as prices climb toward $3.00 per litre, if engine efficiency can consistantly achieve fuel consumption figures of 4.7 l/100km or better.
A major concern for buyers considering an electric vehicle is the purchase price, with only seven percent of respondents willing to pay up to $4000 more for an electric vehicle - and two-thirds of respondents unwilling to pay any premium at all.
Mitsubishi's i-MiEV will go on sale to the wider public in Australia next month for $48,800 - around $14,000 less than the 2010 model, which was offered exclusively to government and corporate fleets.
Despite the significant price drop, the i-MiEV's purchase price is still well above the most miserly petrol- and diesel-powered offerings in the same light-car segment, and more even than the priciest Prius - the iconic green car.
While pricing has yet to be announced, the greenest Fluence is expected to retail for around $30,000 - although buyers will also need to 'subscribe' to a Better Place membership package, the cost of which has not been revealed.
The Deloitte study also showed that most motorists are not satisfied with the 120-180 kilometre driving range of most electric vehicles, with 68 percent of respondents demanding a range 320km or better.
The survey showed that 90 percent of the 500 Australians surveyed travel less than 120km each week day.
