Overview
- Honda confirmed the revised Spec‑2 unit met its internal targets after a Hungaroring filming day and will race at the Dutch Grand Prix on August 21–23.
- The team says the changes are internal to the power unit and include a revised pre‑chamber, altered piston shape, and lubrication tweaks to speed combustion and cut mechanical losses.
- Honda declined to give exact horsepower figures but outside reporting places the first step at up to about 30 hp rather than closing the previously reported ~60 hp deficit to Red Bull‑Ford Powertrains.
- Honda plans a staged rollout with further engine updates scheduled for Monza and Baku and has warned the Zandvoort step should be a meaningful improvement but not an instant cure.
- Aston Martin added a broad B‑spec package in Budapest with limited race gains, so the true competitive impact of Honda’s Spec‑2 will only be known once race weekends show lap‑time and reliability performance.
