Mercedes makes power unit part changes after Bottas failure

Mercedes has changed the control electronics on the power unit of both its Formula 1 cars in response to Valtteri Bottas’ part failure at the Eifel Grand Prix.

Bottas was forced to retire from the race at the Nurburgring two weeks ago after suffering a loss of power due to an issue on his power unit.

Mercedes initially believed the fault was related to the MGU-H, but confirmed earlier this week that it had defined the issue as being electrical. Mercedes confirmed ahead of Friday’s practice running for the Portuguese Grand Prix at Portimao that the failure had been further diagnosed within the control electronics on Bottas’ PU.

As a result, both of its cars will take a new control electronics for this weekend’s running in Portugal.

“Valtteri’s failure in Germany was located to a failed electrical component in the control electronics,” a Mercedes spokesperson confirmed on Thursday evening. “Both he and Lewis will take new modules this weekend, and we have made calibration changes, too, in order to avoid a repeat.

“It’s the second module for both drivers, so within the permitted allocation.”

As it is only the second control electronics component used by both drivers this season, there will be no grid penalty for the change as they are under the season limit. However, it is not yet confirmed if the issue will force a replacement of the control electronics on all of the Mercedes power units throughout the F1 grid. Racing Point and Williams are also powered by Mercedes.

Racing Point drivers Sergio Perez and Lance Stroll are both already on their season limit of two control electronics, as is Williams’ Nicholas Latifi. It means that any new part for these three drivers would trigger a grid penalty.

The setback for Bottas at the Nurburgring dealt yet another blow to his fading F1 title hopes as team-mate Hamilton scooped up his 91st grand prix victory.

The retirement caused Bottas’ deficit to Hamilton to grow to 69 points with six races remaining in the season, prompting the Finn to concede he needs a “miracle” to turn things around.

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…
