The biggest news is a replacement engine, with the 5.4 litre V8 from the outgoing model replaced by a more powerful and more efficient 3.5 litre V6 EcoBoost engine.
The new power plant has twin turbochargers and direct injection, producing “at least” 276kW and 583Nm, with Lincoln claiming ‘best-in-class’ towing ability.
The 2014 Navigator is available in either rear- or four-wheel-drive, with each option featuring a six-speed automatic with SelectShift.
Other mechanical improvements include a new electronic power steering system, updates to the Lincoln Drive Control system and the Continuously Controlled Damping system, allowing the driver to choose between Normal, Sport and Comfort settings.
Exterior-wise, the new Navigator sees the reintroduction of a split-wing grille and the availability of the Reserve Package; which replaces the standard 20-inch wheels with 22-inch polished aluminium wheels.
Inside, the updated SUV gets Lincoln’s new steering wheel design – as seen on the smaller MKC model late last year – along with an 8 inch touch screen and 4.2 inch screens in the instrument cluster.
Lincoln has added a new ‘puddle light’ which illuminates the ground as a passenger opens one of the front doors, providing a virtual ‘welcome mat’.
The 2014 Lincoln Navigator will go on sale to US customers in the second half of this year, with an official unveiling to take place at next month’s Chicago Auto Show.
