Highest MPG for a non-hybrid: Mitsubishi Mirage
Best non-hybrid MPG: 2014 Mitsubishi Mirage?
Mitsubishi says its new Mirage subcompact will get the best MPG of any non-hybrid: 44 mpg (US) highway, 37 city. (Some drivers are already beating that in various economy driving contests.) How? An efficient 1.2L, 3-cylinder engine, very light weight and aerodynamic design.
