Tesla launches long-wheelbase Model Y with 3,040mm wheelbase in US

Tesla's stretched Model Y L, offering 150mm more wheelbase and a six-seat layout, is now available in the US and Puerto Rico.

Tesla launched the long-wheelbase Model Y L in the US and Puerto Rico, adding a six-seat variant with 150mm more wheelbase than the standard model to fill a family-hauler gap left by the discontinued Model X.

"Production is expected to begin in the US in September, which will lead to sales beginning before the end of 2026," Sam Fiorani, analyst at AutoForecast Solutions, said in a recent report.

The Model Y L stretches to 4,969mm to 4,976mm in length with a 3,040mm wheelbase, compared with the standard Model Y at about 4,790mm and 2,890mm. The 2+2+2 seating configuration targets families seeking more rear-seat space than the seven-seat Model Y, whose third row is widely considered suitable only for small children. The model was already launched in China and is now being produced at Gigafactory Texas.

The launch comes as Tesla prepares to report second-quarter deliveries, with independent researcher Troy Teslike estimating 466,000 units versus the analyst consensus of 406,024. TSLA shares have risen 12% this week, heading for their best weekly run in more than two months, though the stock slipped 0.3% in overnight trading Thursday.

The Model Y L fills a critical gap in Tesla's lineup after the company discontinued the Model X alongside the Model S earlier this year, leaving the seven-seat Model Y as its only family-hauler option. The stretched variant's additional length and wheelbase provide meaningful third-row legroom, positioning it against three-row electric SUVs from Rivian and Kia.

Tesla's official social media account teased the launch earlier this week with an image of a stretched dachshund and a "long weekend" caption, prompting speculation among retail traders and Tesla-focused accounts on X. The company did not disclose pricing for the US market.

For investors, the Model Y L represents a relatively low-cost product line extension that could boost delivery volumes without requiring new manufacturing lines. Tesla shares trade at elevated valuations heading into the Q2 delivery report, and the new variant's reception will be a key indicator of demand momentum heading into the second half of 2026.
