Russell Dominates Bahrain Pre-Season Testing While Cadillac Halts Action with Red Flag Incident
George Russell delivered an impressive performance on Friday morning at Bahrain's opening pre-season test, setting the week's quickest lap and surpassing Lewis Hamilton in the process. The Mercedes driver's dominant showing was momentarily disrupted when Cadillac triggered a red flag stoppage during the session.

Mercedes' George Russell proved the class of the field during Friday's morning session at the Bahrain pre-season test, establishing himself as the pace-setter ahead of Lewis Hamilton in Ferrari machinery.
The British driver wasted little time making his mark, posting a benchmark 1m34.075s on soft compound tyres within the opening thirty minutes of action. Russell continued to sharpen his performance throughout the session, subsequently lowering that mark to a 1m33.918s—a time that would stand as the fastest of the entire week to date.
Running in parallel, Hamilton managed a respectable 1m34.209s, positioning himself as the secondary threat on the timing sheets as Mercedes demonstrated its early-season competitiveness.
The morning's running was not without drama, however. Cadillac's involvement in the session resulted in a red flag stoppage, halting proceedings as marshals addressed the incident and allowing recovery operations to proceed.
Russell's commanding display provided an encouraging signal for Mercedes as the team continues its preparations for the 2026 season, while Hamilton's performance highlighted Ferrari's competitive standing heading into the campaign.
