What does sdrive mean?

[Ophelia]

sdrive stands for rear-wheel drive, which means the engine is located at the front and the driving force is at the rear. This significantly improves the vehicle's steering, sporty driving, and comfort. Rear-wheel drive allows for a unique weight distribution, with nearly 50% of the weight on the front axle and 50% on the rear axle, ensuring neutral self-steering characteristics. During acceleration, the dynamic axle load distribution is influenced by the inertial force at the vehicle's center of gravity, allowing the rear axle to receive more driving force. In rear-wheel-drive vehicles, the engine and transmission are usually arranged longitudinally, meaning the cylinders of the engine are aligned parallel to the direction of travel. The engine is mostly installed at the front of the car, and the power is transmitted via a driveshaft to the differential located between the two rear wheels, which then distributes the power to the rear wheels. However, there are also mid-engine and rear-engine designs, which are more common in sports cars.
