SMMT attributes the growth in part to electric vehicles. They say that EVs had their best month ever in the UK with 4.2% market share up from last high of 3.6% in November last year. As we previously reported, the UK saw an important growth of its electric vehicle market last year led by good deliveries of Mitsubishi Outlander PHEV, Nissan LEAF, BMW i3, and Tesla Model S. Tesla has been roughly doubling deliveries of its Model S in the UK every year since the introduction of its right-hand drive version in 2014.
