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 $gsimeq 13$,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$Mtextsubscript{(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.
