We first saw the new vehicle, known then as the TX5, in late 2015. From the outside, it looks like a regular taxi with its black paint job, large front grille and illuminated sign on the roof. Inside, however, is a 1.3 litre, three-cylinder petrol engine, which acts as a generator for a battery pack and electric motor. As a pure EV, it can go 70 miles on a single charge, but with its gas-guzzling aid that rises to 400 miles. Its green credentials are, therefore, limited, but it does meet the "zero emission capable" requirement that will be introduced for all new taxis on January 1st, 2018.
The taxi's cabin has been upgraded too. The new TX has six seats, contactless card machines — a requirement in London since October 2016 — onboard Wi-Fi, USB charging and a panoramic roof. Up front, drivers will have access to a sat-nav with information about traffic congestion and electric charger locations. The screen will also integrate with taxi-hailing apps — think Gett, myTaxi and Kabbee — to help drivers compete with Uber (which for now is still operating in London). It is, in short, a long overdue overhaul for one of the city's most iconic and, for some, beloved vehicles.
