  "textContent": "An electric drivetrain having a primary motor-generator assembly, an electric axle drive unit and a power source. The primary motor-generator assembly includes a primary mover, a first gearbox in driving engagement with the primary mover and a first clutch. The first gearbox is in driving engagement with the primary mover. The electric axle drive unit includes a differential assembly, a second motor-generator assembly in driving engagement with a wheel assembly and a third motor-generator assembly in driving engagement with another wheel assembly. The differential assembly is in selective engagement with the first clutch, the second motor-generator assembly via a first axle clutch, and the third motor-generator assembly via a second axle clutch. The electric axle drive unit is selectively engaged with the primary motor-generator assembly via the first clutch. The second and third motor-generator assemblies include a motor-generator and a reducing gearbox portion.",
