Aside from the new grille and front-end treatment, we expect to see new trim, some interior tweaks, and a re-shuffling of options and standard features. According to a document leaked to FordInsideNews, it may even offer an EcoBoost 3.5-liter V-6 engine in place of the 5.4-liter V-8 in the current model.
That might all sound a touch underwhelming given the Escalade's new powertrains, all-new exterior design, and rather fantastic new interior, but that's because the 2015 Navigator is almost certainly just an update to the current model, rather than an all-new SUV.
An all-new Navigator is thought to be in the pipeline, potentially bringing a completely new look and feel, and a host of other upgrades. It's still not clear when Lincoln might fully update the aging Navigator, but it needs to soon--the Navigator sold just 942 units in December, a 12.9 percent decrease from 2012, and 8,613 in all of 2013. That's a small figure compared to Cadillac's Escalade sales in 2013--the last full year of the outgoing model--which totaled 22,514 units across its three body types (standard, ESV, and EXT).
We'll have the full details on the 2015 Lincoln Navigator, including a gallery of high-resolution photos, as soon as it's unveiled tomorrow.
