Abstract: The process $e+e- \to K+K-\pi+\pi-$ has been studied in the center-of-mass energy range from 1500 to 2000\,MeV using a data sample of 23 pb${-1}$ collected with the CMD-3 detector at the VEPP-2000 $e+e-$ collider. Using about 24000 selected events, the $e+e- \to K+K-\pi+\pi-$ cross section has been measured with a systematic uncertainty decreasing from 11.7\% at 1500-1600\,MeV to 6.1\% above 1800\,MeV. A preliminary study of $K+K-\pi+\pi-$ production dynamics has been performed.
