Honda says second ADUO power unit upgrade was introduced in Madrid

Koji Watanabe, president of Honda Racing Corporation, said Honda brought its second ADUO (Additional Development and Upgrade Opportunities) upgrade as early as Formula 1’s Spanish Grand Prix in Madrid. According to Watanabe, the change was centered on the power unit’s turbocharger.

Aston Martin and Honda had struggled from the beginning of the season. Their form then improved slightly after a major chassis update, while Honda’s turbocharger-related ADUO upgrade had already been introduced at the Spanish Grand Prix.
