BMW UK has an BMW i8 preview configurator live on their site. There are 3 color choices, Ionic Silver, Crystal White and Sophisto Grey. The white and great each come with a choice of accent colors. There are three wheel choices but noticeably missing are the carbon fiber wheels options. Perhaps they're not road legal in the UK, they will not be available in the USA either. On the interior there are 4 leather choices. While this is not the complete configurator there will be very few options on the i8. The i8 will arrive state side in the spring with a starting price of $135,700.
Build your own i8 and let us know how you configured it.
