For 2024, Mercedes has confirmed that it will move away from its ‘size-zero’ sidepods architecture to bring a new car concept after struggling to keep the “capricious beast” that is the W14 within its narrow operating window.
But with new engine rules (that ditch the expensive and complex Motor Generator Unit – Heat) coming in for 2026 alongside a switch to active aerodynamics, for which the research and development will consume resources, the 2025 cars are expected to be evolutionary “close cousins” of what hits the track next year.
As such, Allison reckons teams must place even more emphasis on a strong start to 2024 given it will influence the next design.
Asked whether he agreed with Lewis Hamilton’s recent sentiment that the next six months are critical if eight-time constructors’ champion Mercedes can return to title contention, he said: “It'll be a different car for one thing. So, we won't be working with this one.
“[Lewis] is correct in two senses: it's a new season; it's important that we get off the new season on the front foot.
“But more than averagely so because with 2026 bearing down on us, that car will need to be engineered in 2025.
“It's highly likely that the 2025 cars can be close cousins of the 22024 cars. So doubly important to get the 2024 car good.”
