BMW sDrive

BMW sDrive is a single axle drive architecture that is purpose-built for sport-utility vehicles.

The two-wheel drive systems present at the time were generally purpose-built for car applications in terms of handling and durability.

These vehicles proved popular to general consumers but lacked the drivability and steering preciseness of the company's sedans and sports cars.

However, the slip differential needed to be built more substantially to enable the torque-vectoring system on heavier vehicles.
