From a systematic study of the radio properties of luminous red quasars comma we have found clear evidence that distinguishes them from normal quasars comma suggesting that they are a special stage in AGN co-evolution with galaxies. To complement an on-going VLT-XSHOOTER program to explore the differences in the accretion disks of red quasars at z=1.5 comma we propose new XMM- Newton observations of 5 carefully selected targets comma which comma in combination with an archival dataset of normal quasars comma will allow a controlled study of openPar1closePar differences in nuclear obscuring columns comma openPar2closePar intrinsic X-ray--optical spectral slope comma and openPar3closePar coronal properties. With this comma we aim to uncover whether red quasars have special accretion engines and mass outflow rates.
