  El Gordo (ACT-CL J0102-4915) is an extraordinarily large and bright galaxy
cluster collision. In a previous study, we found that El Gordo is in
$6.2\sigma$ tension with the $\Lambda$CDM standard model when assuming the
nominal mass and infall velocity values from the hydrodynamical simulations of
Zhang et al. ($M_{200} = 3.2 \times 10^{15} M_{\odot}$ and $V_{\textrm{infall}}
= 2500~\textrm{km~s}^{-1}$, respectively). The recent weak lensing study of Kim
et al. showed that the mass of El Gordo is actually $2.13^{+0.25}_{-0.23}
\times 10^{15} M_{\odot}$. Here we explore the level of tension between El
Gordo and $\Lambda$CDM for the new mass estimate, assuming several
$V_{\textrm{infall}}$ values. We find that in order to reduce the tension below
the $5\sigma$ level, the El Gordo subclusters should have $V_{\textrm{infall}}
< 2300~\textrm{km~s}^{-1}$ ($V_{\textrm{infall}} < 1800~\textrm{km~s}^{-1}$
when considering the combined tension with the Bullet Cluster). To the best of
our knowledge, the El Gordo hydrodynamical simulations conducted so far require
$V_{\textrm{infall}} \geq 2500~\textrm{km~s}^{-1}$ to simultaneously reproduce
its morphology and its high X-ray luminosity and temperature. We therefore
conclude that El Gordo still poses a significant challenge to $\Lambda$CDM
cosmology. Whether the properties of El Gordo can be reconciled with a lower
$V_{\textrm{infall}}$ should be tested with new hydrodynamical simulations that
explore different configurations of the interaction.
