The XMM-Newton X-ray observatory is the most powerful instrument for cosmic X-ray spectroscopy to date and particularly suited for spectral diagnostics of supernova remnants. We have chosen three bright, (relatively) young, supernova remnants in the Magellanic Clouds (N103 B, N132 D and 1E0102) to highlight its capability. The high resolution grating spectra show XMM-Newton's unique capability to perform high resolution spectroscopy on X-ray sources of a moderate (few arcminutes) angular extent. The possibility of single ion spectroscopy permits independent measurements of electron temperature, density, ionisation age and velocity profiles. In addition, full spectral modeling also allows for elemental abundance determination.
