The Tesla Model S and Model X date back to 2012 and 2015, respectively and have yet to undergo a major refresh (though the Model S received a new front fascia in 2016). In general, the exterior and interior designs for both have held up exceptionally well but their age is starting to show. We reported last month the EV automaker has big updates planned for these vehicles that'll include new software and hardware. To help reduce pre-facelift supply and complete factory re-tooling, Tesla halted all production for both vehicles in California for 18 days beginning on December 24.

And now the automaker is taking things a step further by requesting its sales team to liquidate all Model S and X inventory by the end of this month. According to Electrek, this liquidation order is for all markets.

The combination of the production shutdown and this new order to sell everything quickly is a clear indicator the updated vehicles are coming very soon. Tesla, of course, has no comment on the matter. Rumors first about a Model S/X refresh first began appearing back in 2018. The original target launch date was supposedly summer 2019 but was delayed in order to focus on ramping up Model 3 production levels.

The planned Model S/X update, sources claim, included a new horizontal center display (similar to the Model 3/Y), a smaller instrument cluster, and a generally higher-quality interior with improved materials. One new piece of hardware is expected to be the "selfie" cam already included in the Model 3 and Model Y.

This is a vital feature for Tesla's planned autonomous robotaxis fleet because it can maintain a visual on paying passengers and can also help prevent vandalism.

While an imminent Model S/X refresh is purely speculation at this time, the sell-off order could also mean there are some sweet deals to be found. In the past, Tesla has enticed customers with offers like free Supercharging for a certain period of time.

Tesla does not have any major online events scheduled in the coming days or weeks as far as we know, so how and when the refreshed Model S and Model X will debut remains a mystery.
