Motor company Ford recently (in 2010) selected ExpressionEngine CMS to power their Ford Fiesta website. The site showcases ExpressionEngine's flexibility with one of the main features of the site being to pull in data dynamically based upon a users specified city and then to use that data in a number of rich interfaces like Google Maps and member information. For a company like Ford, ExpressionEngine would also offer a lot of peace of mind with it's excellent security record and the commercially backed support provided by EllisLabs. Ford joins several other Fortune 500 companies like Nokia, Disney, Sony and Apple who have all selected ExpressionEngine to power some of their online projects.
