Honda Detects a Fault in Aston Martin F1 Power Unit
As a partner providing engines to Aston Martin in Formula 1, Honda has identified a specific aspect that must be improved to achieve maximum performance. The Japanese manufacturer examines the operation of its power unit and compares it with competitors' data. This analysis reveals a main factor that limits the capabilities of the British single-seater. The group of engineers is already acting to solve this issue ahead of the next Grand Prix. 🏎️
The Problem Lies in the ERS Hybrid System
The weakness identified by Honda is linked to how energy is managed in the hybrid system, known as ERS. The collected information indicates that the combustion engine operates at a very high level. However, the transfer of electrical energy between the battery and the electric motor does not reach its optimal state during specific phases of the track. This prevents the driver from using all the power available at the precise moment it is needed, especially when accelerating after slow corners.
Direct Impact on Results:- A lap time loss is generated that can be crucial.
- On circuits with numerous accelerations from low speed, the disadvantage increases.
- Aston Martin notes that its car performs well in fast corners but struggles to match rivals in sectors that demand an immediate power response.
If the power is not deployed at the exact moment, one can only watch as rivals pull away. A matter of timing that costs tenths.
The Solution Lies in the Software
Honda has now prioritized modifying the software that controls the MGU-K (Motor Generator Unit - Kinetic). The goal is to achieve finer synchronization with what the driver demands at each moment, closing the identified performance gap. 🔧
Areas of Work for the Engineers:- Review and optimize the algorithms for controlling electrical energy flow.
- Adjust the hybrid system's response to acceleration demands.
- Improve integration between the combustion engine and the electrical system to deliver power more linearly and efficiently.
Race Against Time for the Next Event
The technical team is working to implement these adjustments before the next championship event begins. Solving this issue is key for Aston Martin to exploit the full potential of its chassis and fight for higher positions. The efficiency of the ERS is confirmed, once again, as a decisive battleground in modern F1.
