Rather than call it vweos or anything intuitive, VW ask you to go to the slightly more poncey, "rediscoveryoursenses.co.uk".
Apparently the domain name sums up the aim of the Eos: to allow drivers to reawaken and rediscover their senses by driving an open-top car. Alternatives considered are rumoured to have included "windinyourbarnet.com", "scorchedpate.co.uk" and "dontforgettoputsuncreamonyourears.net".
