Formula 1 News: Mercedes may scrap upgrade as Russell title hopes fade

Mercedes is considering abandoning its Sepang aerodynamic upgrade after the package made the W17 slower rather than faster, losing performance in qualifying while struggling with drag and balance. Team boss Toto Wolff confirmed reverting to the previous specification is a real possibility, and driver Kimi Antonelli suggested Friday practice in Singapore could be used to compare the two packages. George Russell's title hopes were further damaged after he retired from third place in the Bahrain GP in Malaysia due to a power unit failure.
