Mercedes admits W11 design is triggering gearbox issue

Mercedes thinks that repeat gearbox problems on its W11 would be inevitable with its current car configuration, after revealing that a build-up of electrical noise is triggering its issues.

Mercedes admits W11 design is triggering gearbox issue

With the team still chasing a solution to the difficulties that affected both Valtteri Bottas and Lewis Hamilton at the Red Bull Ring, it has emerged that the matter is not directly related to the mechanical aspects of the gearbox.

Instead, a combination of the layout of the W11 internals, plus the vibrations put through the car by the kerbs in Austria, are causing a perfect storm of trouble for the German car manufacturer.

Mercedes trackside engineering director Andrew Shovlin says that the gearbox problems in Austria were not a one-off in the race, and are something that the team was battling with throughout the first weekend.

"We were we were aware of it on Friday, when you saw that Valtteri had an issue at the end of one of the sessions," said Shovlin. "So that that was the first sign that we had a problem.

"We've had recurrent issues over the course of Saturday. And going into the race, we were expecting it because it seems to be a feature of the model.

"So at the moment, if we build the car and run it, this problem will appear at some point. It's a question of how soon."

Shovlin explained that the cause of the problems is related to a build-up of electrical interference within the car systems, which ultimately begin to impact on the gearbox and its sensors.

"It's not manifesting itself as one thing," he said. "It's basically a buildup of electrical noise.

"That starts to interfere with the various systems. With Valtteri, we saw this around halfway through the race. It got progressively worse with Lewis, and it appeared later.

"But it's an electrical noise that's then affecting a lot of different things."

Mercedes is still looking at what changes it can make to its car for this weekend's Styrian GP in a bid to minimise the electrical noise problem.

While changes may require modifications to the gearbox, it is understood it will not require a totally new gearbox design.

The difference between Mercedes’ stumble and the fall of F1 giants

OPINION: Mercedes endured its worst season of the hybrid Formula 1 era, but was mercifully spared its first winless campaign in over a decade late on. It has owned up to the mistakes it made which led to its troubled W13. And while its task to return to title-challenging contention is not small, its 2022 season seems more like a blip than the beginning of a downward spiral.

How Red Bull's dynamic leader Mateschitz shaped its F1 philosophy

The death of Dietrich Mateschitz last month has not only deprived Red Bull of its visionary founder, it has shorn Formula 1 of one of its most influential benefactors. Mateschitz himself was famously media-shy, preferring to let the brand do the talking on his behalf. And, while it’s now normal to speak of Red Bull F1 titles and champions made, Mateschitz never assumed it would be easy or even possible – as ANTHONY ROWLINSON discovered during this previously unpublished interview from 2006…
