  The string inspired tachyon field can serve as a candidate of dark energy.
Its equation of state parameter $w$ varies from 0 to -1. In case of tachyon
field potential $V(\phi)\to 0$ slower(faster) than $1/\phi^2$ at infinity, dark
energy(dark matter) is a late time attractor. We investigate the tachyon dark
energy models under the assumption that $w$ is close to -1. We find that all
the models exhibit unique behavior around the present epoch which is exactly
same as that of the thawing quintessence.
