I present measurements of the W boson charge asymmetry and
the W boson width (Tau_W) using 350 pb-1 of CDF Run II data. The charge
asymmetry is the first direct measurement, which uses a new technique to
reconstruct the W rapi+dity for constraining its mass; the results will
further constrain Parton Distribution Functions in future fits. The width
measurement relies on a fit to the W transverse mass distribution.
We measure Tau_W = 2032 +/- 71 MeV which is in good agreement with the
Standard Model prediction.
