Adrian Newey Predicts Engine Dominance in 2026 Formula 1 Regulations

Adrian Newey, a key figure in Formula 1 engineering, anticipates that the upcoming technical regulations for the 2026 season could lead to a significant focus on engine performance, reminiscent of the 2014 season when hybrid power units were first introduced. Newey, who will take on the role of managing technical partner at Aston Martin in March, believes that one engine manufacturer could gain a substantial advantage over competitors, similar to Mercedes’ dominance during the initial years of hybrid technology.

New Engine Regulations Overview

The forthcoming regulations will remove the complex and costly MGU-H electric motors, placing greater emphasis on the MGU-K unit, which will harness more energy. Additionally, teams will utilize sustainable fuels to comply with the new standards. An innovative feature will be an override system designed to provide extra power when trailing another vehicle, akin to the current DRS system.

“There’s a significant possibility that early on, the series will become heavily influenced by engine performance,” Newey stated in an interview with German publication Auto Motor und Sport. He noted that the simultaneous overhaul of both chassis and engine regulations is a unique occurrence in Formula 1 history. “This situation adds an extra layer of complexity, as the chassis changes are aimed at compensating for the engine regulations,” he added.

Potential for Engine Dominance

Newey emphasized that the way the regulations are structured could allow one manufacturer to emerge as the clear leader, establishing an engine-dominated environment early in the new formula. “If a manufacturer develops a superior combustion engine, it could maintain a competitive edge throughout the regulation period,” he explained. He also pointed out the challenges for teams currently lagging behind, given the design complexities implied by the new regulations.

On the electrical side, however, there may be more opportunities for teams to catch up, given the broader flexibility in that area. “In terms of fuel, there has been some flexibility introduced. However, with stringent dyno restrictions and current optimization practices, simply changing fuel types may not yield the desired performance improvements,” he noted.

Aston Martin’s New Collaborations

Aston Martin is set to partner with Honda, which will act as its works engine supplier, while Saudi Arabian oil giant Aramco will deliver sustainable fuels. Meanwhile, Audi has entered the fray as a new player in the power unit landscape, having completed its acquisition of the Sauber team. Red Bull Racing is also developing its own engines at its new Powertrains facility in Milton Keynes, in collaboration with Ford.

In addition to these manufacturers, traditional players such as Mercedes, Ferrari, and Honda will continue to compete, with the emergence of General Motors’ Cadillac as a potential sixth power unit provider expected to enrich the competitive landscape in 2026. Renault, conversely, has abandoned its own power unit program, pivoting its Alpine team to become a customer for Mercedes engines.

Design Development Timeline

While engine regulations have been established for some time, teams only recently received the green light to develop their car designs in wind tunnels, following the finalization of technical regulations late last year. As Newey prepares to join Aston Martin, he has indicated that his primary objective will be the 2026 car, although 2025 may still require his input, depending on the team’s needs.

“My focus will undoubtedly be on the 2026 season,” Newey remarked. “However, I anticipate that Lawrence Stroll, the team owner, may want my input on the development of the 2025 model. My actual contributions will remain uncertain until I begin this new role.”

Having been absent from the sport since late April, Newey acknowledges that he has much to learn about the latest regulations. “The engine regulations have been published for some time, but my familiarity with recent changes in chassis design, aerodynamics, and vehicle dynamics needs to be refreshed, presenting a considerable learning curve ahead of my return,” he concluded.
