Nissan Leaf taxis are now operating in Holland, Switzerland, Germany, Portugal, Spain and the UK.According to the automaker the car is a hit with European taxi owner/drivers concerned about running costs, fuel bills and maintenance downtime. The cars are quick-charged two or three times a day using green energy, making sure they're always ready for passengers.'IDEAL FOR TAXIS'Portugal-based taxi driver José Ferreira replaced his diesel taxi with a Leaf. He has driven more than 15 000km so far, covering 80-100 a day, and claims that 70% of his customers liked the experience so much they would choose to ride in an electric taxi again.Globally, Nissan Leaf taxis are helping to cut pollution on the streets of New York, Rio de Janeiro and many cities in Japan.Jean-Pierre Diernaz, director for electric vehicles in Europe, said: "There is little doubt that the Leaf is an ideal vehicle for taxi operators. It's cheap to run and easy to maintain. It's good to drive and passengers like the space and comfort."From a driver's point of view, the Leaf's brisk acceleration allows it to keep with the traffic flow and the growth in quick-charging networks provides easier access to rapid recharging."
