McLaren targets Norris fuel issue - reports

Autosport, Motorsport.com and RaceFans report McLaren has changed Lando Norris’ power-unit peripherals to address a recurring fuel-system issue.

McLaren is reported to have made peripheral changes to Lando Norris’ Mercedes power unit to address a recurring fuel-system problem. Autosport and Motorsport.com both reported the work after linking Norris’ recent straight-line speed deficit to the issue, with Bahrain and Baku cited in their coverage.

RaceFans reported that Norris said the problem had cost him performance in recent races and that he was hopeful it had been solved. In separate Singapore coverage, Motorsport.com reported Norris finished fifth in sprint qualifying after running seventh in SQ1 and third in SQ2.

The team has not confirmed the update in the supplied material, so it remains a reported development. Norris is fifth in the 2026 drivers' championship on 188 points, and the McLaren driver has 11 wins and 16 poles from 161 Grands Prix.
