A new engine has delivered progress, but Monza will expose every remaining weakness.
MONZA, ITALY
Honda has warned Aston Martin that its upgraded Formula One power unit could struggle at the Italian Grand Prix. Monza’s long straights and unusually high proportion of full-throttle running make engine output and electrical-energy deployment especially important, leaving limited opportunities for the chassis to compensate for a power deficit.
The Japanese manufacturer introduced its Spec 2 power unit at the Dutch Grand Prix after modifying the pre-combustion chamber, piston geometry and lubrication system. Honda’s objective was to accelerate combustion, reduce internal friction and improve overall performance. Fernando Alonso subsequently finished ninth at Zandvoort, securing his best result of the season and adding two points to Aston Martin’s total.
The result nevertheless concealed persistent driveability problems. Alonso reported inconsistent power delivery and less refined gear changes, suggesting that some improvements achieved with the original engine specification had been lost. Honda has acknowledged that its power unit remains behind those of its principal competitors despite meeting the internal targets established for the upgrade.
Honda chief engineer Shintaro Orihara explained that Monza will place exceptional pressure on the management of limited electrical energy across its extended acceleration zones. Qualifying is likely to be particularly demanding because lap time at the circuit is highly sensitive to outright power. The manufacturer has therefore adopted realistic expectations instead of presenting the Spec 2 engine as an immediate solution.
Honda engineers have continued dynamometer work at the company’s Sakura development centre, concentrating on stable combustion and more predictable power delivery. Aston Martin is also expected to introduce aerodynamic changes intended to reduce drag and improve straight-line efficiency. These measures may limit the damage, but they cannot completely eliminate the underlying performance gap.
The warning illustrates how far the Honda-Aston Martin partnership still must progress. Early vibration and reliability problems have largely been controlled, while major chassis revisions have moved the team closer to the midfield. Monza will now provide a more severe evaluation of whether those advances represent sustainable recovery or remain dependent on circuits that conceal the car’s weakest characteristics.
