The second-generation Lexus GX has been on sale for ten years now, making it one of the oldest models in the automaker's current US lineup. You would think, then, that an all-new model is long overdue. In 2013, the GX was given an update with the Lexus spindle grille design as well as new LED headlights and LED daytime running lights offered as standard, and now reports have suggested that another update is coming soon. To give us an idea of how it will look, Russian website Kolesa has produced a convincing-looking render showing the refreshed Lexus GX's design details.

Don't expect any revolutionary changes, as Lexus will likely update the GX to match other models in its current lineup. Lexus' polarizing spindle grille looks even wider due to the thicker surround that features a chrome finish on the outer sections. Elsewhere, the headlights have more prominent LED lamps and reshaped running lights that follow the upper corner of the grille.

At the back, the designers have added new L-shaped taillights that give the SUV a more modern appearance and more closely match the automaker's current lineup, as well as a blacked-out rear bumper.

Since the changes are likely to be only cosmetic, we're not expecting the refreshed GX to get any powertrain changes. The current model is powered by a 4.6-liter V8 that sends 301 horsepower and 329 lb-ft of torque through a six-speed gearbox to an all-wheel-drive system with an electronic locking differential.

No word yet when the updated Lexus GX is likely to break cover, but we wouldn't surprised if it debuts before the end of the year. The next major auto show in the US is the Los Angeles Auto Show in November, but Lexus could reveal it online sooner before its public debut.
