Constant speed means constant velocity. Constant velocity means an object is covering same distance in equal intervals of time. So how is it possible to have acceleration. Acceleration means speed is increasing with equal intervals of time.
So its not possible according to my logic.

A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
A body moving with constant speed in a circular path has acceleration changing at every point.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
I wonder what is the constant speed of this moving car
