US electric car maker, Tesla, has officially called time on two of its longest-serving models, the revolutionary Model S and the large falcon-winged SUV Model X.

Tesla confirmed the axing via social media platform, the Elon-Musk-owned X, stating that “the last Model S and the last Model X have been produced at Fremont Factory”.

Musk first floated the idea of killing off both models in January of this year, claiming that the world’s second-largest maker of electric vehicles was repurposing its Fremont facility – where both Model S and X are manufactured – to manufacturing its forthcoming Optimus humanoid robots.

Sales of Model s and Model X had been in decline for years (in 2025, Model S accounted for just 0.6 per cent of total Tesla sales while X fared just slightly better with 1 per cent.

Tesla’s sales success continues to be dominated by Model Y (66.4 per cent of total sales) and Model 3 (30.5 per cent) with the polarising Cybertruck adding 1.5 per cent to the brand’s total volume.

The culling of the range ends 14 years of Model S production while Model X enjoyed an 11-year run.

Tesla farewelled the pair with a special run of ‘Signature Edition’ models, based on Plaid model variants. Just 250 Signature Edition Model S and 100 Model X, priced at US$159,420 have been released.

Neither Model S or Model X have been available in Australia since 2020 after Tesla confirmed it would no longer make those models for right-hand drive markets.
