Judging from the teaser image shared by Lexus, which seems to be a still taken from a video showing parts coming into or out of the crossover, the update won't be a radical redesign of the vehicle currently in showrooms.
The headlight unit seems to be smaller than today's iteration, and there are new LED internals too. Other key features, including the brand's spindle grille and the separate swoosh-style LED daytime lights, remain in place.
In addition to a lightly refreshed exterior, Lexus is promising "interior enhancements that add convenience and functionality". So, expect to see the latest version of Lexus' Remote Touch infotainment system and, possibly, a larger screen.
Lexus isn't saying much more about the updated NX ahead of its April 19 debut.

The NX has sold in good numbers for brand down under, with 3308 finding new homes last year.
Although it finished fifth out of 11 in the medium SUV over $60,000 category, behind the Mercedes-Benz GLC (4454), Land Rover Discovery Sport (3824), BMW X3 (3824) and Audi Q5 (3599), it more than held its own against its European competition.
It also outsold its larger sibling, the RX, by 1396 units. Together the two crossovers accounted for almost 58 per cent of Lexus sales in Australia in 2016.
