UNITED KINGDOMSmith Electric Vehicles has signed an agreement with LTI Vehicles Ltd. (LTI) to produce the world's first battery powered, zero emission urban taxi cab. Under the agreement, LTI and Smith will produce an all-electric version of LTI's TX4 black cab, branded the TX4E. Preliminary specifications for the vehicle are a top speed of 50mph and a range in excess of 100 miles on one battery charge.

The TX4E will contain all the conventional features of the TX4, but will be powered by Smith's advanced electric drive train and lithium-ion iron phosphate battery pack. It will be manufactured in the United Kingdom for the domestic urban taxi market and sold through LTI's distribution network.

Based on current electricity prices, the vehicle will cost less than 4p per mile to run, according to Smith.
