The BMW Concept X6 ActiveHybrid features a two-mode active transmission. Utilizing electronics, the transmission is able to operate in two different settings: the first for starting from a standstill and low speeds, the second for higher speeds. Based on an electrical continuously variable transmission (ECVT), the innovative transmission allows the drivetrain to run at continuously variable speeds while ensuring efficiency throughout the complete operating range of the vehicle. Unlike conventional hybrid transmissions, the two-mode transmission is more compact and lightweight—increasing efficiency while improving the X6’s driving and handling dynamics.—Michael Harley
