Replacing Mercedes’ highly successful GT3 race car is proving difficult because it set a very high standard in performance, reliability, and balance. The existing car has been competitive across many championships for years, so creating a new model that matches or improves on it requires careful engineering and testing.
Mercedes engineers must ensure the new GT3 car stays true to the regulations, safety standards, and performance expectations that teams and drivers rely on. Balancing power, handling, and durability — while also meeting new technical rules — makes the development process complex and demanding.
Overall, the challenge isn’t just building a new car, but building one that can live up to the legacy of the current championship‑winning GT3 model.
