Tesla’s Secret 3-Row SUV Prototype Flaunts Cybertruck-Style Stainless Steel

Tesla’s next “Cyber” vehicle might not be a pickup or a robotaxi—it could be a hulking, three-row SUV. A brief shot in Tesla’s Master Plan 4 promo video appears to show a lineup of design mockups in the studio, including a clay Cybercab in the foreground and, on a shelf behind it, a blocky, stainless steel SUV that looks very much like a stretched Cybertruck.

The concept, as teased by the silhouette, seems to turn the Cybertruck’s bed into additional cabin space, adding a third row of seats. In other words, imagine the Cybertruck’s angular stainless steel design, but with the cabin extended all the way to the tail, creating a full-size family hauler.

Why the idea makes sense:
– The Cybertruck’s footprint is already in full-size SUV territory at 18.6 feet (5,683 mm), giving Tesla a ready-made platform for a three-row layout.
– Fans have long asked for a truly spacious, three-row Tesla with generous cargo volume. While the current lineup offers configurations with extra seats, a full-size SUV would better address families and utility-focused buyers.
– Styling continuity with the Cybertruck could streamline design and manufacturing while tapping into the strong brand identity of the “Cyber” family.

The teaser arrives alongside lofty ambitions in Master Plan 4, including the claim that a significant share of future revenue could eventually come from the Optimus humanoid robot program. But for now, vehicles remain the core of Tesla’s business, and glimpses like these suggest the design team is actively iterating on what comes next.

Tesla’s chief designer recently hinted that several future designs are in the pipeline and set to be revealed soon. If a Cybertruck-based SUV is among them, expect a focus on:
– Three-row seating for six or seven
– A cavernous, squared-off cargo area
– The same edgy stainless steel aesthetic
– Potentially shared components and architecture with the Cybertruck to speed development

Key takeaway: nothing here is an official product announcement, but the studio mockups are a compelling clue. If Tesla greenlights a Cyber SUV, it could fill a high-demand niche for a full-size, all-electric three-row—one with the unmistakable, polarizing lines of the Cybertruck and the practicality families and adventure seekers want.
