NEARLY 50pc of drivers would consider buying an alternatively fuelled car, according to a survey.
As many as a quarter were likely to make a "green car" purchase in the next five years, the RAC poll showed.
But the cost of environmentally friendly vehicles was a problem for around 25pc.
And the small range of battery-powered electric vehicles was also a concern.
Concerns over range remain a constant challenge for makers of electric cars.
Those surveyed felt that, of the various greener motoring options, the most popular was likely to be low-emission petrol or diesel-engined cars, followed by hybrid electric.
Only 10pc reckoned that pure electric would be the most popular, with only 8pc plumping for hydrogen-powered vehicles.
RAC technical director David Bizley said the survey showed opinions on alternatively-fuelled vehicles were still mixed.
He added that it was important to adopt low-carbon alternatives as they become available and affordable.
But he added: "In order for this to happen, consumers' perceptions of low-carbon vehicles must be changed."
