Tesla’s long-rumored three-row electric SUV may be closer to a US debut than previously expected. A Tesla Model YL prototype has been spotted driving on Interstate 280 in California’s San Francisco Bay Area, marking the first confirmed sighting of the extended-wheelbase SUV on American roads.
The sighting is significant not just because it confirms the Model YL’s physical presence in the United States, but also because it contradicts earlier suggestions from CEO Elon Musk that the vehicle might never reach the North American market.
Prototype Spotted Near Tesla’s Core Operations
The image of the Tesla Model YL test mule was shared on X by user Michael R Carroll, who reported seeing the vehicle traveling northbound on I-280. He described the SUV as noticeably longer than the standard Model Y, calling it “a looong boi” — a fitting observation given the Model YL’s extended proportions.
Interstate 280 runs through Silicon Valley and is a familiar testing route for Tesla vehicles. The highway connects key locations including Tesla’s Palo Alto engineering headquarters and its Fremont factory. Over the years, Tesla has frequently used this corridor to test early prototypes before official launches.
This latest sighting suggests that Tesla’s development of the Model YL for the US market has reached an advanced stage, moving beyond factory testing and into real-world validation.
Earlier Clues from Gigafactory Texas
The road sighting follows earlier hints that Tesla was preparing the Model YL for North America. Just weeks ago, drone footage captured at Gigafactory Texas appeared to show Model YL body structures wrapped in protective material, indicating that units had likely been shipped from Tesla’s Shanghai factory.
While those images hinted at internal testing and assembly preparation, the appearance of a fully assembled prototype on public roads is a much stronger signal. It indicates that Tesla is now testing performance, safety, and software systems in real driving conditions — typically one of the final before launch.
The Tesla Model YL is a stretched version of the popular Model Y, first introduced in China in August 2025. Designed to meet demand for a larger family-friendly electric SUV, the Model YL features a longer wheelbase and expanded body dimensions.
Compared to the standard Model Y, the YL adds approximately 150 mm (5.9 inches) to the wheelbase and about 180 mm (7 inches) in overall length. This increase allows for a true three-row seating configuration with six seats arranged in a 2-2-2 layout, featuring second-row captain’s chairs.
The key advantage of the Model YL is its improved third-row usability. While the standard Model Y offers an optional third row in the US, those seats are widely considered too cramped for adults. The extended design of the Model YL provides significantly more legroom, making it a practical option for families needing genuine six-passenger capacity.
Since its launch, the Model YL has expanded beyond China into markets such as Australia, New Zealand, and parts of Southeast Asia. It has also secured European regulatory approval. Notably, in China, the Model YL has quickly gained popularity, accounting for roughly one-third of all Model Y sales.
When Tesla first introduced the Model YL, Elon Musk stated that US production would not begin until late 2026 and suggested that it “might not ever” be sold in America. He cited the anticipated rise of autonomous driving as a factor that could reduce the need for larger passenger vehicles.
However, recent developments suggest a shift in strategy. Tesla is expected to phase out the Model S and Model X later this year, which would leave a gap in its lineup for customers seeking vehicles with more than five seats.
The Cybertruck, while innovative, targets a different segment and does not directly replace the passenger capacity of a three-row SUV. This makes the Model YL a logical addition to Tesla’s portfolio, particularly in the US market where larger vehicles are in high demand.
Strong Market Demand for Larger EV SUVs
The growing popularity of three-row electric SUVs underscores the potential success of the Model YL in North America. Competing models from brands like Kia, Hyundai, and Volkswagen have gained traction by offering spacious interiors and family-friendly features.
Given that the Model YL has already exceeded expectations in international markets, analysts believe it could perform even better in the US. American buyers typically favor larger vehicles, and the lack of a true three-row Tesla has been a noticeable gap in the company’s lineup.
Pricing is expected to play a key role. In China, the Model YL launched at around $47,000. In the US, estimates suggest a starting price between $51,000 and $53,000, positioning it competitively against other electric crossovers in the segment.
The appearance of the Model YL prototype on California roads strongly suggests that Tesla is accelerating its timeline. While Musk previously pointed to late 2026 as a potential start for US production, the current level of testing indicates that the launch could arrive sooner than expected.
Industry observers now believe that Tesla could begin taking US orders as early as late 2026, with deliveries potentially starting in early 2027.
For now, the road test sighting serves as the clearest indication yet that the Tesla Model YL is not just a global product — but one that is very likely headed to American driveways in the near future.
