Grounded in design DNA from the best-selling Scuderia XX family and inspired by high-performance sport, the imposing new XX Kers reveals Scuderia Ferrari's signature race-car influence in its bold, strong aesthetic elements. KERS stands for Kinetic Energy Recovery System, the cutting-edge technology developed by Ferrari to recover energy wasted in braking. Crafted in stainless steel ion-plated finish, the round XX Kers case, styled with extended sport lugs and crown protector, is truly commanding in size.
