Following a surprisingly successful Formula 1 weekend in Malaysia, expectations were remarkably high at Aston Martin for Singapore, a venue that should have suited the AMR26 package exceptionally well on paper. However, the competitive picture at the Marina Bay Street Circuit proved rather disappointing, with performance falling well below pre-race expectations.
Fernando Alonso pointed directly to problems with the Japanese power unit after the chequered flag, specifically regarding overall driveability. In response to the setbacks, Honda promptly sent both its engineering staff and power units back to Sakura for thorough, in-depth investigations into the root causes.
Those rigorous checks ultimately revealed no specific hardware faults within the internal components. Instead, it quickly emerged that the manufacturer was primarily struggling with persistent turbo lag—the frustrating delay between pressing the accelerator pedal and feeling the turbocharger genuinely kick into action.

This technical hurdle is certainly not entirely new, having previously hampered driveability when a fresh power unit specification was introduced earlier at Zandvoort. It was precisely to eradicate this exact issue that Honda utilized its second ADUO token of the year in Madrid to introduce a brand-new turbocharger design.
Nevertheless, when speaking directly to Motorsport.com, Honda's chief trackside engineer Shintaro Orihara admitted that the issue unexpectedly resurfaced to trouble them during the Singapore Grand Prix weekend, posing ongoing challenges for the development team moving forward.
