Saab 9-5 launches with TCS on but VolvoS60R naturally launches much better with the help of AWD. With better torque and less power loss on the wheels against S60Rs AWD system, Saab with Abbott ECU just kills S60R until 220 kmh. Then R comes back into play again.
This Volvo was my new purchase to replace the Saab 9-5 Wagon but I kept the Saab instead.
