  We present optical and infrared photometry of the classical nova V906 Car,
also known as Nova Car 2018 and ASASSN-18fv, discovered by ASASS-SN survey on
16.32 March 2018 UT (MJD 58193.0). The nova reached its maximum on MJD 58222.56
at $V_{\rm{max}} = 5.84 \pm 0.09$ mag and had decline times of $t_{2,V} = 26.2
$ d and $t_{3,V} = 33.0 $ d. The data from Evryscope shows that the nova had
already brightened to $g'\simeq 13$\,mag five days before discovery, as
compared to its quiescent magnitude of $g=$20.13$\pm$0.03. The extinction
towards the nova, as derived from high resolution spectroscopy, shows an
estimate consistent with foreground extinction to the Carina Nebula of $A_V =
1.11_{-0.39}^{+0.54}$. The light curve resembles a rare C (cusp) class nova
with a steep decline slope of $\alpha=-3.94$ post cusp flare. From the
lightcurve decline rate, we estimate the mass of white dwarf to be $M_{WD}$ = $
< 0.8$M\textsubscript{\(\odot\)}, consistent with $M_{WD}=0.71^{+0.23}_{-0.19}$
derived from modelling the accretion disk of the system in quiescence. The
donor star is likely a K-M dwarf of 0.23-0.43\,\Msun, which is being heated by
its companion.
