the changes, the Limited trim became the only version available in Canada and Mexico as Eddie Bauer (in Canada) and King Ranch trims (in both Canada and Mexico) were discontinued, while the Philippines and the Middle East replaced the Eddie Bauer with the XLT trim. The Middle East also started to get all of the 5 US level base trims, including the new XL trims that took the XLT's place and the King Ranch trim. With the 2015 refresh, the Expedition EL US level trims are the same as the standard versions: XLT, Limited, King Ranch, and Platinum, all four available in rear wheel and four wheel drive. The Canadian Expedition Max are only featured in Limited and Platinum level trims, also available in RWD and 4WD. Mexico's Expedition Max are available in rear wheel drive XLT only, but available in RWD and 4WD Limited versions. The Philippines, Republic of China (Taiwan), and Middle East ELs are only available in 4WD Limited trims. With the introduction of the Expedition Max for the 2018 model year as the successor to the first generation Expedition EL, Ford made the vehicle available globally, with North America in late 2017 and selected countries in early 2018. Four-wheel drive system Selectable automatic full-time Control Trac four-wheel drive designed by BorgWarner is standard on all 4x4 Expeditions. There are four modes: Two High mode, Auto mode, Four High mode and Four Low mode. Each mode can be selected via a rotary control dial on the dash. The Expedition's system uses a two-speed dual range BorgWarner transfer case with a software controlled variable intelligent locking center multi-disc differential. The four-wheel drive system does not use a planetary or bevel geared center differential, which are typically found in permanent four-wheel drive systems where torque is supplied to all four wheels. {| class="wikitable" style="margin: 1em auto 1em auto; text-align:center;" |- !colspan=3|Selectable Automatic Full-Time ControlTrac Four-Wheel Drive |- | style="width:10%;"| Mode| style="width:10%;"| Drive type| Operation|- !
