Mercedes Brings Old Parts to Singapore With New Questions

The championship leader expected its latest upgrade to move it forward. Singapore could reveal why the opposite appeared to happen.

Mercedes will evaluate both its latest upgrade package and its previous specification at the Singapore Grand Prix as it investigates the performance drop that left it struggling at Sepang.

Toto Wolff confirmed the comparison in the team’s Singapore preview. What had been a possible response to a difficult weekend is now part of Mercedes’ plan to understand its car.

“F1 doesn't offer simple answers and we need more evidence before drawing firm conclusions,” he said.

More downforce, unanswered questions

The upgrade was supposed to strengthen Mercedes’ position at the front. Instead, the Bahrain Grand Prix in Malaysia left the team trying to explain why the expected gains had not translated into stronger overall performance.

Deputy team principal Bradley Lord said the drivers could feel improvements through medium- and high-speed corners. The slower sections remained a problem.

In Mercedes’ post-race debrief, Lord described a possible interaction between the updates, track temperature and Sepang’s rough surface. Drivers were having to use the throttle to help rotate the car through slow corners, adding to the challenge of managing tire temperatures.

That leaves Mercedes with several factors to separate. A difficult weekend does not, by itself, establish that the new package is worse.

A comparison with consequences

Wolff said Singapore’s different circuit characteristics would help Mercedes build a clearer understanding of its performance.

The Race reports that the team is due to split the old and new specifications between its two cars across the weekend. Mercedes’ own announcement confirms that both packages will be evaluated, without specifying which driver will use each version.

That distinction matters. Testing the previous specification gives the engineers a reference against which to assess the newer parts. It does not mean Mercedes has already decided to abandon the upgrade.

The comparison should help establish whether the problems follow the latest package to another circuit or whether Sepang’s particular conditions played a larger role.

Little practice, plenty to learn

Singapore’s Sprint format makes that investigation more demanding. Teams have just one practice session on Friday before Sprint Qualifying, with the Sprint and Grand Prix qualifying following on Saturday.

Mercedes therefore has to combine its development work with preparing both cars for competitive sessions almost immediately.

The aim is to leave Singapore with a clearer basis for choosing its next steps. Before Mercedes can extract more speed from the upgrade, it needs to understand why the expected progress was so difficult to find.
