We present a preliminary analysis of XMM-Newton observations of the oxygen-rich supernova remnant G292.0+1.8 ( MSH 11-5 4 ) .
Although the spatial extent of the remnant is 8 ^ { \prime } the bright central bar is narrow ( 1-2 ^ { \prime } ) resulting in RGS spectra of a high spectral quality .
This allows us to spectroscopically identify a cool , kT _ { e } = 0.3 keV , and underionized component , resolve details of the Fe-L complex , and resolve the forbidden and resonant lines of the O VII triplet .
We are also able to constrain the kinematics of the remnant using Ne IX as observed in the second order spectrum , and O VIII in the first order spectrum .
We do not find evidence for O VII line shifts or Doppler broadening ( \sigma _ { v } < 731 km s ^ { -1 } ) , but line broadening of the Ne X Ly \alpha line seems to be present , corresponding to \sigma _ { v } \sim 1500 km s ^ { -1 } .
