M.R. was a Romanian microcar developed by Radu Manicatide and built in 1945 by Industria Aeronautică Română in Brașov. It had a rear-mounted, rear-wheel-drive two-cylinder engine producing 11.5 brake horsepower and an aerodynamic convertible body. A second model, a three-wheeler with an air-cooled engine, followed in 1957. Neither model reached production.
