Saab called to Austria to enjoy with fans and friends at the XWDays all-wheel competence, snow and Saab.
There was enough snow again when Saab now presents its XWD four-wheel drive system at the XWDays in the Austrian Alps. It is an electronically controlled four-wheel system that delivers torque where it is needed. This prevents unwanted oversteer, understeer and instability.
The result of the Saab XWD is better handling, better stability and a sporty driving experience.
When starting up and accelerating on dry roads, up to 80 percent of the power is transferred to the rear wheels for maximum acceleration. With increasing speed, power and torque shift to the front wheels.
At constant speed on a straight road, up to 95 percent of the torque is transferred to the front wheels for optimum stability and the lowest possible fuel consumption.
When cornering and simultaneously accelerating more power is sent to the rear axle, which causes an easier turning of the vehicle. When starting off in slippery conditions, such as when the vehicle is on ice with one wheel and the other on asphalt, the better traction wheel gets more power.
This is ensured by the electronically controlled differential (eLSD) on the rear axle. This provides the best-meshing wheel with up to 80 percent of the rear axle torque.
The same thing happens when driving at a constant speed and unexpectedly ice or a surface of water appear on the road.
In an evasive maneuver at high speed, the eLSD increases stability by forcing both rear wheels to the same speed.
The Saab high-performance models also include a newly developed front suspension. It is called HiPerStrut - short for High Performance Strut. The connection to the body and subframe corresponds to that of a McPherson strut.
During the ride in the snowy Alps, the four-wheel drive system showed its capabilities in all situations. There were no weaknesses when driving on ice or driving on fresh snow. The Saab vehicles mastered both uphill and downhill. Saab does not have to hide in the field of all-wheel technology.
