Although the 2018 Lincoln Navigator shares its mechanical underpinnings and aluminum body with the Ford Expedition, this luxury SUV manages to establish its own identity. It comes propelled by a twin-turbocharged 3.5L V6 engine generating 450 horsepower, managed by a 10-speed automatic transmission, possibly making it one of the fastest large SUVs available. The Lincoln Navigator offers three trims – Premier, Select, and Reserve - all of which include adaptive suspension, LED headlights, heated and ventilated front seats, triple-zone automatic climate control, along with driver aids such as adaptive cruise control, forward collision warning, and blind-spot monitoring. The Navigator's infotainment system includes a 10-inch touchscreen, compatibility with Apple CarPlay and Android Auto, and a 14-speaker Revel audio system. For 2018, its design improves upon previous generations with styling that's more expressive and distinct.
