Narrative:
On arrival to ewr while reaching crank intersection at 7;000 feet; turbulence began to increase. After being handed off to ny app; the turbulence began to increase to moderate. We were cleared direct teb down to 3;000 feet and 210 knots; but at the same time; the turbulence got worse (severe) and [we were] unable to control the speed or altitude (a/P disconnected). [The] speed jumped as high as 270 [knots] and altitude was unstable. I advised ATC of our encounter and situation; advised we were unable to control. Controller asked if we needed to climb but; shortly after we were in smooth VFR conditions.dispatch and ATC should have taken more actions based on prior arrivals and suggested other alternatives to arriving aircraft.
