[Neither the Intense 12 nor its scores have changed since this review was posted two seasons ago.] Powerdrive is Dynastar’s name for a 3-piece sidewall which functions as a unique damping system. Stacked on edge alongside the core, it consists of a soft inner layer, a hard center section and a dynamic outer wall. Any time a viscoelastic material, like that used in the inner piece of Powerdrive, is bonded to Titanal (center part), the resulting element will act as a natural shock absorber, so the forebody of the Intense 12, where the Powerdrive feature resides, should stay nice and quiet on hard snow. But Powerdrive serves another, more vital function: by un-coupling the core from the outer sidewall, the central laminates that dictate the ski’s behavior are allowed to shear, moving as the ski is pressured. This enhanced suppleness allows the ski to respond to subtle variations in the snow surface, maintaining contact, control and speed.
