Mercedes Unveils Insights from W17 Upgrade Trial

Mercedes has been busy experimenting with its W17 car, aiming to squeeze more performance out of its latest upgrades. According to deputy technical director Simone Resta, the revamped W17 generates more downforce than its predecessor, but the team is still figuring out how to best utilize it. At the Singapore Grand Prix, Mercedes split their strategy: George Russell ran the older package, while Kimi Antonelli took the updated car for a spin.

The initial test of the new W17 at the Bahrain Grand Prix wasn't exactly a fairy tale, with Max Verstappen clinching the win while Russell ended with a DNF, necessitating an engine change and penalty for Singapore. This mishap opened the door for Mercedes to dive deeper into understanding their new setup.

Speaking on the Mercedes’ Nu Silver Arrows Radio Show, Resta shed some light on the team's findings. "We aimed to deliver more performance and more downforce, and we've measured increased downforce," Resta explained. However, he noted the complexities involved: "The challenge is not straightforward. It’s a grey area with multiple variables. We’ve delivered downforce, but not uniformly across all operating points. This affects the car's balance, requiring drivers and setups to adapt accordingly."

Resta also highlighted the difficulty in adapting to the diverse track conditions faced in Malaysia and Singapore. These differences in tyre grip, sliding, and drag present a unique set of challenges. "Drawing conclusions from such varied tracks is tough," he admitted. "We’ve identified more downforce, but we need to address a few issues, particularly given the car's increased balance."

When asked about the car's stronger front end, Resta confirmed: "Yes, the front is stronger, perhaps more than anticipated. We need to re-centre the operating window, which takes time, especially during a sprint weekend where time is limited."

Bradley Lord, Mercedes' deputy team principal, praised Antonelli’s performance over the weekend, noting his significant improvement and how he adapted to the challenges posed by the upgraded car. Antonelli managed to finish on the podium in Singapore, despite earlier struggles with the car's balance.

Lord elaborated: "Initially, the updated car seemed less competitive, but Kimi refocused and made progress. The wet sprint race provided valuable insights, revealing an oversteery car that improved as the front tyres wore down. This led to better balance, allowing Kimi to match the leaders' pace in qualifying and the race."

Antonelli's efforts were crucial in guiding the team, helping them understand the direction needed to access the car's potential more reliably. "There’s higher peak performance potential," Lord commented, "but the margin for error is narrower than with the previous car." It seems Mercedes has found a promising direction, but perfecting it will require careful navigation.
