Nissan NV200 London taxi unveiled

Nissan has revealed a new London taxi, dubbed the ‘NV200 London Taxi', following the compact van's selection as New York City's Taxi of Tomorrow. It promises to be just as controversial in the UK as it is Stateside. The NV200, which measures in at 1,860mm high, 4,440mm long and 2,100mm wide, seats five passengers with three on a rear bench and two rear facing fold down seats while the removal of the front passenger seat increases luggage space, much in the same way as the traditional London taxi.
