George Russell will race Mercedes' older-specification car, while Kimi Antonelli will run an upgraded package at the Singapore Grand Prix as the team bid to get to the bottom of why the updates introduced in Malaysia did not deliver the expected performance.

The world championship leaders brought their first big upgrade to their W17 cars since the end of May to last week's race but unexpectedly endured a challenging weekend on F1's return to Sepang, with Max Verstappen instead proving the dominant force and claiming Red Bull's first win of the season.
