It has an extremely economical 800 cubic centimetres (49 cu in), direct-injection turbo gasoline engine mated to a continuously variable transmission, and a claimed fuel mileage of 3.1 litres per 100 kilometres (91 mpg‑imp; 76 mpg‑US).[33][34][35] Q-concept, first shown at the 2011 Tokyo Motor Show, is a bubble car like the MIT CityCar, Nissan Pivo or Toyota PM.
