The Wi-Fi can be used on up to 10 devices and features Apple CarPlay and Android Auto capabilities compatible with Ford SYNC3 and Ford Pass. A dual vista panoramic sunroof is available as an optional feature. The 2018 Expedition was only available in four trim levels, as the King Ranch trim was discontinued after the 2017 model year. The three primary trims, XLT, Limited, and the top-of-the-line Platinum, were available to regular customers, while the fourth trim, XL, was exclusive to rental companies, corporate fleets, and government agencies, as it did not have as many features as the other three trims. The Expedition retains its unique (standard) eight passenger seating on all trims like before, with optional seven passenger seating.
