A rather detailed 'grown-up' review of the new Prius, is quite analytical, but not in a boyzone/topgear way, and is rather positive about most aspects.
Perhaps the rear design detail leaves a fair bit left to wish for , and the rather un-European interior white splashes, but over all 4 strong stars....although second to the Audi Etron in the e-vehicle stakes (£35k!)
