Following a deal inked for the supply of London Cabs to overseas markets, the London Taxi Company has appeared to have sent a development mule to Sweden for cold weather testing, as spotted by our spy photographers. Owned by Chinese automaker Geely, the Black Cab seen here is a fully-electric version which is set for launch late in 2017 as a 2018 model.

In addition to its full-EV driveline, the London Cab is expected to also come with the option of a range-extender unit, a la BMW i3, according to our spy photographers. As reported earlier, the EV London Cab will retain the hallmarks of a London taxi – wheelchair access, luggage capacity located beside the driver, a small turning circle, and face-to-face passenger seating for six people.

In relation to the TX4 which will be supplied in the aforementioned 10-year deal for the Australia and New Zealand export markets, the production version of this EV mule will likely come to light as the TX5, which will be built alongside the TX4 at the LTC plant in Ansty, Conventry.

The Coventry plant will have the capacity to produce 36,000 vehicles annually once its new R&D and production facilities are operational – a production capacity 10 times that of the old facility. Prior to this, Nissan put forth a reinterpreted NV200 for London Taxi duties, though that project has been put on hold indefinitely due to struggles with emissions standards.
