Saab announced that their XWD all-wheel-drive system, formerly reserved for the V6-powered 9-3, will now be optional on the 9-3 models equipped with the 2-litre, 4-cylinder turbo engine. Featuring with a different rear floor, the convertible version won't benefit from the system.
In normal driving conditions, the XWD delivers over 90% of the power to the front wheels in order to limit fuel consumption. However, during abrupt acceleration manoeuvres, part of the torque is sent to the rear wheels, improving traction and weight distribution. Depending on the conditions, the system can distribute up to 100% of the power either to the front or the rear wheels.
What's more, the XWD system, developed conjointly by Saab and Haldex, uses a limited slip rear differential that improves the car's stability in corners.
These modifications will be introduced on the 2009 Saab 9-3.
