A car issue in the next races in Bahrain and China prevented Palmer from showing his true form but he bounced back in the Russian Grand Prix, finishing a strong 13th having started 18th on the grid. He repeated that result in the Spanish Grand Prix, coming home ahead of team-mate Magnussen. After an early exit in Monaco, a water leak put paid to his race in Canada before he finished the European Grand Prix in Baku, Azerbaijan, in a creditable 15th.
