Mercedes W17 Completes Rain-Soaked Silverstone Shakedown

Mercedes has officially kicked off the 2026 Formula 1 era, completing a wet shakedown of the new W17 at Silverstone. Just hours after the car's unveiling, George Russell took to the rain-soaked Northamptonshire track to begin validating the team's latest challenger on Pirelli's grooved demo tyres.

Why it matters:

This marks the first time Mercedes has run its full 2026 package—combining the new chassis with the all-new V6 hybrid power unit—on track. With the most significant technical regulations overhaul since 2014, these initial laps are critical for validating systems and ensuring the car is ready for the intense pre-season testing schedule ahead.

The details:

• Debut Conditions: Russell navigated the wet track gingerly, giving the W17 its first real "heartbeat" in representative running conditions despite the challenging weather.
• Promotional Running: The session utilized one of Mercedes' two allotted promotional filming days, which are restricted to 200km. This allowed engineers to gather initial data without the pressure of official test limits.
• Power Unit Context: While Alpine had previously fired up Mercedes' 2026 power unit, this was the first proper shakedown of the works team's complete chassis and engine package under its own banner.
• Home Advantage: Silverstone served as the logical venue, located near the team's Brackley chassis base and Brixworth engine facility.
• Grid Activity: Mercedes joins Audi, Cadillac, Racing Bulls, and Alpine as teams that have already completed early shakedowns, meaning nearly half the grid has turned a wheel in 2026 spec.

What's next:

The focus now shifts to Barcelona for the first official pre-season test from January 26–30, which will be held behind closed doors. Following that, the team will head to Bahrain for two further tests in February that are open to fans and media, providing the first true look at the competitive order.
