Subaru is best-known for its WRC-winning Impreza rally car, and its be-spoilered road-going counterparts, but the Legacy represents the other face of the brand.
The full-time four-wheel drive system divides power between the front and rear axles and splits torque to send most to the axle with most grip when it gets slippery, and the limited-slip differential divides torque between the rear wheels. It's a simple but effective system, and under normal driving conditions, it is set up to be rear-biased, to give the feeling of a driver-focussed rear-wheel drive car.
