A four-speed transaxle for a high efficiency electric vehicle comprises four planetary gear sets that is operatively connected to an electric motor, four electric caliper brake systems and one stage gears. The four-speed transaxle produces its first speed ratio when a first and third electric caliper brake systems are disengaged and a second and fourth electric caliper brake systems are engaged. Second speed ratio results when the first and fourth electric caliper brake systems are engaged and the second and third electric caliper brake systems are disengaged. Third speed ratio results when the second and third electric caliper brake systems are engaged and the first and fourth electric caliper brake systems are disengaged. Fourth speed ratio is produced when the first and third electric caliper brake systems are engaged and the second and fourth electric caliper brake systems are disengaged.
