Mercedes-Benz Unimog U 400

Released in 2011 as a flagship model for the Lego Technic theme, the 8110 Mercedes-Benz Unimog U 400 was developed to celebrate the 60th anniversary of the real-world Unimog platform. As a licensed set, it represented a significant collaboration between Lego and Mercedes-Benz, aiming to capture the versatile, heavy-duty nature of the legendary German utility vehicle. The design process focused on translating the complex pneumatic functions of the actual Unimog into a playable model, incorporating a working crane arm, winch, and a realistic steering system that provided a challenging build for enthusiasts of mechanical engineering models.

Upon its release, the set was highly regarded within the fan community for its technical sophistication and aesthetic accuracy, particularly in its striking bright green and silver color scheme. Designers utilized the Power Functions system to actuate the pneumatic arm, demonstrating a high degree of fidelity to the vehicle's hydraulic systems. It remains a notable entry in the Technic lineup, often cited as a benchmark for how licensed vehicles can effectively integrate complex structural movement with authentic automotive branding.
