The data indicates that all Nissan Leaf models within the 2011-2018 range are electric vehicles, with 100% of the sample relying solely on electric power. Additionally, there is no available information on the engine capacity for these vehicles, which is typical given their electric nature, as they do not have traditional internal combustion engines. This highlights the consistent electric propulsion of this model series and suggests that engine capacity data is not applicable or recorded for these EVs.
