Ferrari headed the timesheets in the second practice session at the 2016 Chinese Grand Prix as Kimi Raikkonen went fastest ahead of Sebastian Vettel, with Mercedes duo Nico Rosberg and Lewis Hamilton in third and fourth, respectively.
Rosberg headed team-mate Hamilton in the first practice session on Friday as there were problems galore in Shanghai, with Williams' Felipe Massa and Renault driver Kevin Magnussen both having tyre issues and prompting two red flags.
Read on for a recap of the day's action.
Here are the results from the second session on Friday:
A terrific performance from both Ferraris indicated that they may be able to compete with the two Mercedes drivers come Sunday's race—especially as Hamilton has been handed a five-place grid penalty.
Hamilton and Rosberg were the early pace-setters in the second session but were first eclipsed by Vettel, before Raikkonen put in a storming 1:36.896 lap.
Rosberg finished two tenths down on the Finn and will be looking to get back on top in third practice on Saturday ahead of a crucial qualifying.
Daniel Ricciardo looked in very consistent form as he finished fifth-fastest ahead of Max Verstappen in the Torro Rosso.
And both Force India drivers finished in the top 10, with Nico Hulkenberg seventh and Sergio Perez ninth.
Valtteri Bottas was 10th, but his Williams team-mate Massa could only finish 14th despite avoiding trouble in the second practice session.
McLaren pair Fernando Alonso and Jenson Button were 11th and 12th, respectively.
There was early drama for Esteban Gutierrez in the Haas as his brakes caught fire, forcing him back into the pits, per Formula 1:
Meanwhile, Magnussen had to sit out the second session as the issues with his car were investigated, per Renault Sport F1.
Here is the classification from the first practice session:
Massa suffered two left-rear-wheel failures, while Magnussen's issue was a suspected broken left-rear suspension.
In total, the session was stopped for half an hour under two red flags as debris was cleared from the track and officials investigated the issues.
Formula E driver and racing commentator Karun Chandhok provided further information:
Hamilton had some problems as well as he spun twice during the session at Turn 11, but he escaped without any damage to his car and was the early pace-setter.
He was eclipsed late on by Rosberg as the German set a time of 1:38.037 to head Hamilton by 0.146 seconds.
Rosberg then had a problem of his own and crawled back to the pits at the end of the session because of an apparent "engine issue," later diagnosed as an ignition problem, per BBC Sport's Andrew Benson.
Sebastian Vettel was over half a second down on Rosberg in his Ferrari but still finished third-fastest, with Daniel Ricciardo fourth in the Red Bull.
Ferrari preceded Red Bull again a little further down the timesheets as Kimi Raikkonen was fifth ahead of Daniil Kvyat.
Jenson Button was eighth in his McLaren, with team-mate Fernando Alonso 12th following his return to action after he missed the last race through injuries sustained in a crash at the season-opening Australian Grand Prix.
The Spaniard has now been declared fully fit to take part in this weekend's action after passing medical tests following first practice, per BBC Sport.
