Radical UK-based Gordon Murray Design has branched out from “petrol-miser” vehicles like the T.25 to develop what it calls "the world’s most efficient electric car”. Joining forces with British engineering firm Zytek Automotive, the company has announced an all-electric three-seater city car known as the T.27 (27th design). Helped by a £4.5 million (US$7.5 million approx.) investment from the UK government-backed Technology Strategy Board, the new R&D project has a total of £9 million (US$15 million approx.) with which to develop four prototypes by February 2011.
