At a time when EV manufacturers are eager for efficiency gains of 2-3% in their powertrains, any new technology capable of providing 10% or more would transform the state of competition among vehicle OEMs (writes Rory Jackson).

With an eye towards enabling that, US company ePropelled has developed and patented a new type of electric motor architecture, which it has manufactured and installed in a Tata Tiago hatchback and which it displayed at the Cenex-LCV show in the UK in September.
