Jolyon Palmer out at Renault, Carlos Sainz in, after Japanese GP
Kvyat back to partner Gasly at Toro Rosso
Jolyon Palmer will leave Renault after this Sunday's Japanese GP with Carlos Sainz replacing him from the next race in Austin.
Daniil Kvyat, dropped from the last two grands prix, will in turn return to a seat at Toro Rosso to race alongside the newly-promoted Pierre Gasly from the US GP.
Sainz had already signed a deal to race for Renault next season but the Spaniard will now join his new team four races early.
Palmer had previously insisted he would complete the 2017 season with Renault but announced his imminent departure on his Instagram page several hours after qualifying at Suzuka.
"Tomorrow's Japanese GP will be my last race for Renault," he said.
"With my grid penalty I'll be starting near the back but I will be giving it my all as always.
"Thanks everyone for the support during the last 2 years, it means a lot!"
Palmer is set to start the race from 18th after receiving a 20-place grid penalty for engine component changes.
