Professional taxi drivers will be swapping their current cars for Nissan Leaf electric cars this coming weekend. A fleet of Nissan Leafs will be driving around London, offering free ‘taxi' rides.

To grab a ride, all a prospective passenger has to do is send a Tweet that incorporates the hashtag ‘#6XCHEAPER' and their chosen destination. Nissan is also using the activity to gather consumer feedback on a potential taxi of the future.

"This is part of a campaign designed to get people to turn on to 100% electric driving by busting many of the myths and highlighting the many benefits of electric cars, including incredibly low fuel costs,” explained Jim Wright, managing director of Nissan GB.

“By offering free taxi rides, we aim to show hundreds of people just how practical and affordable the Nissan Leaf is to run. As each journey costs us so little, we're not charging passengers - there's no point quibbling over a few pence."

The fleet of Nissan Leaf EVs will be based at their very own ‘taxi rank' at the Truman Brewery, near Liverpool St Station, and will be giving free rides to destinations across London. That means as far west as Turnham Green or to the O2 Arena in the east.

The Nissan Leaf cabs will go south of the river as far as Clapham and as far north as Hampstead. They will be operating from 10am to 6pm on both Saturday and Sunday and driven by professional drivers from car service operator, Climatecars.
