Fun build that grew in beauty

This was such a great build to make. It starts really slow, a ton of small connectors in each bag, but by bag 6 or 7, it really begins to get fun. I love the look of it and how sleek and sturdy it feels. The stickers are high quality and make the car pop in pictures!

A Precision-Built Bonding Experience

Building the LEGO® Technic Mercedes-AMG F1 W14 E Performance was far more than assembling bricks—it was a shared journey of discovery, patience, and joy. I had the privilege of constructing this intricate model with my kids and juniors, and the experience was nothing short of transformative. Quality Time That Builds More Than a Model From the very first step, this set invited collaboration. Each phase of the build became an opportunity to teach and learn—whether it was interpreting the manual, identifying parts, or troubleshooting together. It fostered teamwork, communication, and a sense of accomplishment that grew with every completed module. Engineering Education in Disguise The backend mechanics of the W14 are brilliantly designed. As we explored the suspension system, differential gears, and aerodynamic shaping, the kids gained hands-on insight into real-world engineering principles. It sparked curiosity and led to meaningful conversations about how F1 cars function under the hood. Patience Meets Playfulness This build demands focus and precision, but it rewards you with immersive fun. Watching the juniors take their time, problem-solve, and celebrate small victories was deeply rewarding. The process taught patience, resilience, and the value of iterative progress—skills that go far beyond the LEGO table. Final Verdict The LEGO Technic Mercedes-AMG F1 W14 E Performance isn’t just a model, it’s a modular learning experience and a bonding catalyst. Whether you're an F1 enthusiast or simply looking for a meaningful way to spend time with younger minds, this set delivers on every front.

My experience

I have built loads of Lego sets before this but this is my first technics f1 set. And overall it’s an amazing set. The building techniques used and the details are amazing. I’m a massive f1 fan. But I did feel like there was a step missing when it came to adding the front wing from underneath the car. And there was a couple other steps that weren’t as clear as they could be. Other than these tho this set is a must have for any f1 fan
