u right, it will be very slow, but it has many other advantages. They made it because of lessons learned in Chechnya (where the Russians found out that using light IFV's is completely suicidal against an enemy equipped with RPG's). It is especially suited for urban fighting. The 30mm cannon can reach up to 90 deg to fire into windows and upper stores of houses. The top of the tank is protected against RPG fire and the unmanned turret further increases protection.
All in all, this vehicle was made for use in the worst sorta guerillia warfare. It doesn't have to be fast coz an IFV cannot move fast in urban terrain anyways.
