plug-in Priuses (Priuii?), maybe it's time to bite the bullet and finally move to the UK... just like you've been telling all your friends you're going to do one of these days. According to a report, Toyota is gearing up for the first trials of the ultra-high-MPG car starting tomorrow at an event in London's Hyde Park. An invite mailed to select members of the media (British media, we assume) states: "the purpose of our UK trial is to evaluate not only vehicle performance, but also the electrical infrastructure required, as well as driver behaviour and expectations. The results will play a key role in preparing for the future commercialisation of Plug-in Hybrid technology." So if you've ever wanted to watch one of these planet-huggers race silently around a British landmark, here's your chance.
