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 off and accelerating on dry roads, up to 80 percent of the power is transferred to the rear wheels to enable 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 to ensure optimum stability and the lowest possible fuel consumption.
When cornering and accelerating at the same time, more power is sent to the rear axle, which makes steering the vehicle easier. When starting off in unevenly slippery conditions, for example when the vehicle is on ice with one wheel and on asphalt with the other, the wheel with better traction is supplied with more power.
This is ensured by the electronically controlled differential (eLSD) on the rear axle. The best gripping wheel is supplied with up to 80 percent of the rear axle torque.
The same thing happens when driving at constant speed and unexpectedly ice or a surface of water appears on the road.
During an evasive maneuver at high speed, the eLSD increases stability by forcing both rear wheels to rotate at the same speed.
A newly developed front suspension is also used for the Saab high-performance models. It bears the name HiPerStrut - the abbreviation for high performance strut. The connection to the body and subframe corresponds to that of a McPherson strut.
While driving in the snowy Alps, the all-wheel drive system showed its ability in all situations. No weaknesses emerged either when driving on ice or when driving on fresh snow. The Saab vehicles mastered both the uphill and the downhill descents. Saab doesn't have to hide in the field of all-wheel drive technology either.
