  We addressed the physical and kinematical properties of Wolf -- Rayet [WR]
central stars (CSs) and their hosting planetary nebulae (PNe). The studied
sample comprises all [WR] CSs that are currently known. The analysis is based
on recent observations of the parallax, proper motion, and color index of [WR]
CSs from the Gaia space mission's early third release (eDR3) catalog, as well
as common nebular characteristics. The results revealed an evolutionary
sequence, in terms of decreasing T$_{\text{eff}}$, from the early hot [WO 1] to
the late cold [WC 12] stars. This evolutionary sequence extends beyond [WR] CS
temperature and luminosity to additional CS and nebular characteristics. The
statistical analysis showed that the mean final stellar mass and evolutionary
age of the [WR] CS sample are 0.595 $\pm$ 0.13\,M$_{\odot}$ and 9449 $\pm$
2437\,yr, respectively, with a mean nebular dynamical age of 7270 $\pm$
1380\,yr. In addition, we recognized that the color of the majority ($\sim$
85\%) of [WR] CSs tends to be red rather than their genuine blue color. The
analysis showed that two-thirds of the apparent red color of most [WR]s is
attributed to the interstellar extinction whereas the other one-third is due to
the PN self-extinction effect.
