Honda on Monday, 14 September 2026 announced a significant mid-season leadership change in its Formula 1 power unit development programme, with Yoichiro Fukao set to replace Tetsushi Kakuda as Large Project Leader from 1 October 2026. The reshuffle comes as customer team Aston Martin endures one of its worst competitive seasons in recent memory.

The Leadership Transition

Fukao, currently serving as Deputy Leader of the F1 Project, will step up to the top role as Kakuda moves aside. Honda framed the move as a deliberate, planned handover rather than a crisis response. 'This organisational change is a planned transition designed to ensure the reliable transfer of technical expertise to the next generation of engineers,' the Japanese manufacturer said in an official statement.

Honda also pointed to the evolving regulatory landscape as a key driver. 'Following the introduction of the new regulations in 2026, and with further regulatory changes expected from 2027 onwards, Honda aims to establish a robust development framework and deliver a highly competitive PU by transitioning to the new structure at an early stage,' the statement added. Critics, however, will note the timing — mid-season shakeups of this nature rarely occur without competitive pressure playing a role.

Fukao's Background and Pedigree

Fukao's association with Honda stretches back to 2002, when he began his career developing engine and gearbox control systems. He subsequently pivoted to Honda's MotoGP programme between 2009 and 2011, before returning to work on hybrid systems for three years. He first took on the role of Deputy Leader of the F1 Project in 2017, and reprised the position in 2022 as Honda charted its return to the sport. His technical breadth — spanning combustion, gearbox, hybrid, and MotoGP disciplines — is seen as an asset as Honda navigates the increasingly complex power unit regulations of the modern era.

Aston Martin's Dire 2026 Season

The backdrop to Honda's reshuffle is a deeply troubled campaign for the Silverstone-based Aston Martin outfit. The team has accumulated just three Constructors' Championship points all season, all of them contributed by veteran former world champion Fernando Alonso. Alonso collected a single point for finishing 10th at the Monaco Grand Prix and two more for a ninth-place finish at the Dutch Grand Prix.

His team-mate, Lance Stroll, is yet to open his account, with a best finish of 13th at the Hungarian Grand Prix. At the recent Spanish Grand Prix, Stroll retired due to brake failure while Alonso finished 17th, two laps down. The team sits only above debutants Cadillac in the Constructors' standings — a side that has yet to score a single point in 2026.

Honda's Power Unit Under Scrutiny

Honda's power unit has reportedly struggled to match even the midfield on both outright pace and reliability. This is a notable departure from Honda's earlier partnership with Red Bull Racing, under which it won multiple Drivers' and Constructors' Championships. The Japanese manufacturer's current supply arrangement with Aston Martin represents a fresh chapter, but one that has so far failed to deliver the competitiveness both sides had publicly targeted ahead of 2026's sweeping regulatory overhaul.

With further rule changes expected from 2027, the pressure on Fukao's incoming leadership team to accelerate development and close the performance gap will be considerable. How quickly Honda can translate this structural change into on-track gains will be watched closely by the F1 paddock.
