Info
After introducing our first fully electric vehicle, SG06E, in 2025, our main goal for 2026 was to apply the lessons learned. The accumulator and cooling concept were completely redesigned, while frame and suspension were refined to improve performance. Aerodynamics were updated, and the Electronics Department introduced a new in-house vehicle control unit and extensive software updates. SG07E is also Seagulls Luebeck’s first driverless vehicle. Happy racing, and see you on track!
