A gauge model of generation nonuniversality proposed 10 years ago predicted that the {τ} lifetime should be longer than what it would be in the standard model. This has been confirmed by recent e⁺{e}^{{{-}}}$ to Z data, although the statistical significance is only 2.3{σ}. We show that this model is also consistent with other precision electroweak measurements, and in particular it contributes negatively to the {ρ} parameter measured at the Z peak.
