The fuel cost can be as low as 1p per mile

The 'G-Wiz' cars will be available to staff needing to travel around the city in the course of their duties.

Two will operate from the council's premises at Wilder House, the other three are based at the Create Centre.

At both premises, the cars' batteries can be recharged using mains electricity generated from renewable energy sources.

'Sustainable transport'

The cars are said to be ideal for stop-start city driving with a top speed of 40mph, a range of 40 miles and fuel cost as low as 1p per mile.

The scheme is part of the Vivaldi Project, a European green-transport strategy led by five city authorities, of which Bristol is one.

Councillor Helen Holland, said: "Air quality is a major issue in Bristol and yet most people don't realise that the average vehicle emits nearly one tonne of carbon dioxide into the atmosphere every year."

"By piloting this scheme, we hope to lead by example and demonstrate our commitment to supporting sustainable transport initiatives."
