We present optical and infrared photometry of the classical nova V906 Car, also known as Nova Car 2018 and ASASSN-18fv, which was discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) on 2018 March 16.32 UT (MJD 58193.0). The nova reached its maximum on MJD 58222.56 at Vmax=5.84{+/-}0.09mag, and had decline times of t_2,V_=26.2days and t_3,V_=33.0days. The data from Evryscope shows that the nova had already brightened to g'~13mag five days before discovery, as compared with its quiescent magnitude of g=20.13{+/-}0.03. The extinction toward 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 light-curve decline rate, we estimate the mass of the white dwarf to be MWD=<0.8M{sun}, consistent with M_WD_=0.71_-0.19_^+0.23^ derived from modeling the accretion disk of the system in quiescence. The donor star is likely a K-M dwarf of 0.23-0.43M_{odot}, which is heated by its companion.
