Ford's 2018 Expedition will enter its fourth generation with a more powerful V-6 engine, lighter-weight body and frame, and an array of technology upgrades such as onboard Wi-Fi, the SYNC 3 infotainment system, and more connectivity, Ford has announced.

Ford unveiled details about the 2018 Expedition ahead of the Chicago Auto Show, where the vehicle will make its debut. Ford showed the vehicle in Dallas with local firefighters and Dallas Cowboys football players.

Ford is remaking the Expedition with a high-strength aluminum-alloy body and redesigned high-strength steel frame, which will reduce weight by about 300 pounds.

A more powerful turbocharged 3.5L EcoBoost will replace the existing engine. Ford will pair it with a 10-speed automatic transmission.

Ford has added more than 40 driver-assist technologies, including enhanced active park assist, an available 360-degree camera view, lane-keeping aid, adaptive cruise control with stop-and-go, collision avoidance detection, and a blind spot monitor.

New interior technologies include wireless charging on the front center console, a Wi-Fi hotspot supporting up to 10 devices up to 50 feet away, a headrest-based rear entertainment system, SYNC 3 that supports Apple CarPlay and Android Auto, SYNC Connect with FordPass for remote connectivity, and advanced cargo management system.
