Procedure; Aircraft
We were given a climb to 14;000 feet after level off at 6;000 feet where we were in constant light/moderate turbulence. Controller asked us to expedite climb to 14;000 for traffic. I open climb that gave Thrust Climb/Open Climb in the FMA. When aircraft had approximately 1;000 FPM climb; I put thrust levers in FLX/MCT (Maximum Continuous Thrust) to give the aircraft more thrust to expedite. The aircraft with the autopilot on lagged in pitching up to the flight director and airspeed jumped from 250 to 270. I opted for selected speed and put 230 knots to initiate a faster climb rate. Speed was exceeded for approximately 30 seconds.
After departing EWR 22R on the EWR4 SID; we leveled off at 6;000. We were then given an additional climb with the exception to expedite the climb. At this point the; Pilot Flying (Captain) advanced the thrust levers to MCT. The airspeed started to rise above 250 knots; however; the aircraft was very slow to become fully involved in the climb. Momentarily; the airspeed indicated approximately; 270 knots indicated. The Captain allowed the automation to make the proper corrections.
A320 crew reported exceeding 250 knots leaving 6;000 feet during turbulence departing EWR citing inadequate autoflight system response to pilot inputs.
