Volvo Car Group has chosen Tenneco Inc.’s continuously variable semi-active
suspension (CVSAe) as a standard feature on its limited run XC90 First
Edition seven-seat SUV.
CVSAe dampers enhance the comfort and handling of a vehicle’s ride by
continuously adjusting all four shock absorbers up to 100 times per second...
The dampers can be switched from standard to sport or comfort mode at any
time to match driver preferences for a more comfortable, more dynamic or
more sporty ride.
CVSAe suspension will be available as an option on all XC90 models produced
from now on http://www.tirebusiness.com/article/20141117/NEWS/141119928/vol
