Tesla's US sales fell sharply in November, reaching their weakest point in nearly four years. According to exclusive data shared with Cox Automotive, sales dropped to about 39,800 units from 51,513 a year ago. This decline comes despite Tesla launching cheaper 'Standard' versions of its popular Model 3 and Model Y in October, priced about $5,000 less than earlier base models. The cheaper vehicles were expected to soften the impact of the Trump administration ending the $7,500 federal EV tax credit in September. However, the lower-cost models failed to attract enough new buyers. Stephanie Valdez Streaty, director of industry insights at Cox, said, "The drop certainly shows there is not enough demand for the Standard variants that were supposed to boost sales after the tax credit expiry." She added that sales of the Standard models cannibalize those of the Premium versions, especially the Model 3. Overall, US EV sales dropped over 41% in November, affecting many carmakers. Despite Tesla’s sales slump, its market share rose to 56.7% from 43.1% a year earlier. The slowdown is part of a wider trend; Tesla deliveries declined last year for the first time due to high interest rates, low consumer confidence, and growing competition from cheaper EVs in China and Europe. Analysts expect another sales drop this year because Tesla’s vehicle lineup includes mostly older models with minor updates. The Cybertruck, Tesla’s newest model, has struggled to capture a big audience. According to Streaty, "Tesla has a serious challenge on its hands next year when several other automakers are planning to roll out cheaper vehicles that are also full of fun features." She said, "The answer is that Tesla needs a completely new vehicle in its fleet. Period." Tesla is also facing reputation issues linked to CEO Elon Musk's political activities, which have sparked protests. To attract buyers, Tesla now offers 0% financing on the Standard Model Y and has lowered prices on both the Standard Model Y and Model 3 in the US. Shawn Campbell, adviser at Camelthorn Investments, told Reuters, "I think the bottom line is, if the demand was there they wouldn't be offering 0% financing." He added, "The solution for the demand issue ultimately needs to be new, fresh models."
