A coincident time of flight technique is used to investigate fast ion-induced CO molecule fragmentation with swift 
and multicharged 
heavy ions. The results concern the strong interaction regime for which no data have yet been reported. Kinetic energy release distributions, branching ratios and multi-electron removal cross sections are determined for each dissociation channel of 
ions (Q = 2-9). The general trend, from the perturbative regime to the strong interaction regime, is analysed in the light of recent ion-atom advances. The use of recoil ion momentum spectroscopy to study one dissociative single ionization channel - with simultaneous excitation - greatly improves the experimental KER resolution. Furthermore, it allows a coincident measurement of the angular and kinetic energy release distributions. This technique is proved promising for molecular spectroscopy studies.
