Kimi Raikkonen topped a Ferrari 1-2 in Friday’s second practice in Shanghai as the Maranello pairing pipped Mercedes on their super-soft run.
Mercedes opted for an early run on the option tyres with Nico Rosberg posting a 1:37.133 while Lewis Hamilton, who has a five-place grid penalty for Sunday’s race, was 0.196s down.
Daniel Ricciardo slotted his RB11 into third place ahead of Max Verstappen while Ferrari opted to concentrate on long runs for the first half of the session.
Raikkonen lined up P18 as he covered an 18-lap run on the softs before questioning whether there was “any point in keeping going because it is absolutely s**t.” Sebastian Vettel was P20 as he put in 15 laps on the mediums.
Swapping to the super-softs saw a meteoric rise for Vettel, who went quickest with a 1:37.005. Minutes later, though, he was beaten by Raikkonen.
The Finn posted a 1:36.896 to edge his team-mate by 0.109s while Rosberg dropped to third, 0.237s down. Hamilton was fourth, 0.433s off the pace.
Ricciardo completed the session as best of the rest ahead of Verstappen, Nico Hulkenberg and Carlos Sainz.
After FP1’s tyre failures, all believed to be related to bodywork, Friday’s second session saw yet more issues.
Heading out for his first run, the right-hand side of Pascal Wehrlein’s headrest became detached, flapping around in the cockpit of his Manor.
Meanwhile Esteban Gutierrez’s Haas caught fire with a massive amount of flames coming from both his rear brakes. His mechanics were out in force with the fire extinguishers as he carefully pulled into the pits but it took some time – and a whole lot of foam – to put out the fires.
Gutierrez did not take any further part in the session and ended without a time to his name for the day as he also missed FP1 with an electrical issue.
Another driver not to post a lap time in FP2 was Kevin Magnussen. Following his tyre troubles in FP1, Renault opted not to let him run while they investigated the cause.
