In a desperate attempt to salvage success from the clutches of failure, Porsche’s engineers and drivers fought hard at the 2024 IMSA SportsCar Championship season opener. The previous year’s disappointing debut at Daytona left the team plagued with hybrid battery and gearbox problems. However, this time around, things went relatively smoothly, except for the No.6 car’s penalty for failing to adhere to controlled powertrain parameters. Fortunately, this problem was rectified through software fixes, preventing it from recurring in all four machines.
Despite the setback, Felipe Nasr managed to secure victory on the track, defeating pre-event favorite Cadillac by a mere 2 seconds. This triumph allowed Michael Steiner, a member of the executive board for development at Porsche AG, to proudly accept the team’s trophy on the podium, marking Porsche’s record-breaking 19th overall success. Back in Stuttgart, there were jubilant celebrations and pats on the back for a job well done.
In the aftermath of the race, Jonathan Diuguid, PPM’s managing director for the program, and Raul Prados, the lead race engineer of the victorious No. 7 car, shed light on the issue. Diuguid explained that the No.6 car was the unlucky one to experience the powertrain problems first, allowing the team to learn from its mistakes and prevent a repeat occurrence. Prados added that although their car did not encounter the same problems, the team took precautions by applying the solution before facing any issues.
Why did the powertrain issue only affect the No.6 car and not the others? Prados could not provide a definitive answer, suggesting it may have been a matter of timing or coincidence. The two cars were identical, making the discrepancy even more perplexing. Diuguid further emphasized the complexity of the systems used to control energy regeneration and deployment, involving various controllers and intricate scenarios. Factors like brake lock-ups, driver maneuvers, and even taking a curb at the Bus Stop Chicane could violate the controller, leading to powertrain issues.
Once the issue occurred in the No.6 car, the team focused on analysis and countermeasures. Prados and the race engineers collaborated with the operations room to implement solutions and prepare the drivers. They emphasized driver instructions and adjustments to ensure adherence to controlled powertrain parameters. Unexpectedly, these countermeasures required sacrificing performance to provide larger margins for control limits, creating an ongoing analysis process for future improvements.
Unlike everyday experiences with smartphones and laptops, where software updates are routine, the Porsche 963s did not require system reboots during the race. This was a notable improvement from the testing phase of the previous year. The necessary software was already programmed into the car’s electronic brain, but the drivers had to select the correct settings using the steering wheel controls. Prados emphasized the team’s efforts to assist the drivers and their ability to adjust parameters without the need for software updates.
Overall, Porsche’s ability to adapt and overcome powertrain issues at the 2024 IMSA SportsCar Championship highlighted their resilience and determination. The initial setback with the No.6 car served as a valuable learning opportunity, enabling the team to prevent similar issues in the future. Although sacrifices were made in terms of performance, the ultimate victory and record-breaking success validated their efforts. Porsche showcased the importance of continuous analysis, collaboration, and swift countermeasures to overcome unexpected challenges and secure victory on the track.
