How a new clutch paddle fixed Kimi Antonelli's race starts
A defining feature of the early 2026 Formula 1 season was the surprisingly poor race starts from the Mercedes cars, particularly from current championship leader Kimi Antonelli.
Despite the Silver Arrows consistently locking out the front row in qualifying, they were invariably being out-dragged into the first corner by their main rivals at Ferrari or McLaren. However, this glaring deficit in startline acceleration has steadily been eradicated by the Mercedes engineering team. The breakthrough was evident during the Montreal Sprint, where the team successfully retained their 1-2 formation into Turn 1 for the very first time all season.
So, how did they fix it? Partly, the solution stems from intensive software recalibration. Engineers have been working overtime to better align the battery deployment, turbo spool, and internal combustion engine during that critical, high-torque moment when the drivetrain is put under maximum load at lights out.
But the physical hardware has also played a massive role, specifically in giving the drivers a much better, tactile feel for the clutch bite point.
The two arrows on Antonelli's new clutch paddle in Montreal indicate how it has been sited higher than before compared to the old version used in Miami.
This ergonomic focus has been particularly critical for Antonelli. In Montreal, the young Italian debuted a brand-new clutch paddle, specifically reshaped and repositioned to suit his physical preferences.
Antonelli has physically smaller hands than his teammate, George Russell. Consequently, he was having to stretch his fingers uncomfortably to operate the standard paddle design, resulting in a less precise feeling during the crucial clutch-release phase.
The new paddle is mounted noticeably higher on the steering wheel, drastically reducing the required finger stretch. Furthermore, the finger holes have been custom-molded to perfectly match Antonelli's physiology. This bespoke ergonomic change has allowed the championship leader to be far more consistent in achieving the optimal balance between clutch slip and wheelspin for the ultimate getaway.
Mercedes' Monaco Hopes
Looking ahead, Mercedes is likely facing its most significant challenge of the season at the upcoming Monaco Grand Prix.
The performance pattern of the 2026 Ferrari suggests their car will be incredibly potent around the low-speed, twisting layout of the Principality. The Ferrari chassis has proven highly compliant over aggressive kerbs and bumpy street circuit surfaces---a trait absolutely essential for a fast lap in Monte Carlo.
Historically, Ferrari has excelled in Monaco since 2021. Even during their less competitive campaigns (such as '21 and '25), the Scuderia inevitably shines on this track, possessing a combination of mechanical qualities that seem perfectly configured for the tight confines.
Additionally, the lack of long, flat-out straights in Monaco will neutralize the power unit advantage Mercedes currently holds over Ferrari. Furthermore, the famously short gear ratios of the McLaren could provide them with a distinct traction advantage over Mercedes out of the slow hairpins.
While Mercedes has secured pole position for every main Grand Prix so far this season (with only Lando Norris breaking that streak in the Miami Sprint), extending that monopoly this weekend is far from a foregone conclusion. With all eyes on the Principality, the latest edition of the Monaco Grand Prix promises to deliver a spectacular, multi-team battle for pole.
