Built on a larger new platform, the 2007 Toyota Yaris hatchback is likely improve on the sales of the outgoing Toyota Echo that it replaces, if for no other reason that gas is priced high. The Echo failed to gain much traction in North America, its weird design condemning it as a last-resort teenager car. But Toyota does nothing if not learn from past mistakes – theirs and others – and the Yaris corrects several issues that consumers had with the Echo: styling is subtler and more professional, there’s a roomier interior, and shoppers have the luxury of choice between a sedan and a hatchback.
