In an all-wheel drive (AWD) vehicle (10,42), torque carrying connections are provided between the powertrain and all four wheels (12,14, 22,24). A multimode mechanical clutch (48) or clutches are provided to selectively disconnect two of the wheels (12,14,22,24) from the powertrain during operating conditions where disconnection improves the performance and efficiency of the AWD vehicle (10, 42). The multimode mechanical clutches (48) may be installed at various locations of the AWD vehicle (10,42), such as within a front or rear differential (20,30), between a half axle (16,18,26,28) and a differential (20, 30) or between a half axle (16,18,26,28) and a corresponding wheel (12,14,22,24), or within a transfer case (36) or power transfer unit (44).
