In April 2001 SN 1993J was observed with both the PN and
MOS cameras of the XMM-Newton observatory, resulting in
about 
s of acceptable observation time.
Fit results with both the PN and MOS2 camera spectra
studying different spectral models are presented. The
spectra are best fitted in the energy range between 0.3
and ~10 keV by a 2-component thermal model
with temperatures of
keV and 
keV,
adopting ionization equilibrium. A fit with a shock model also
provides acceptable results. Combining the XMM-Newton data
with former X-ray observations of the supernova, we discuss
the general trend of 
and
the bump of the X-ray light curve as
well as former and recent spectral results in the light of
the standard SN model as first proposed by Chevalier in 1982.
