Daniel Ricciardo maintained his advantage in the second practice session for the Singapore Grand Prix. Having set a new track record during the morning session he lowered it to 1’40.852, leaving him half a second clear of team mate Max Verstappen.
However an error by Sebastian Vettel meant Ferrari didn’t reveal their full potential. He set the quickest time in the first sector at one point but clipped the wall at turn ten and had to pit.
While all the other drivers set their quickest time on the ultras-soft tyres, Vettel did his on softs and ended the session outside the top ten.
The Mercedes pair got closest to the two Red Bulls but Lewis Hamilton was seven-tenths off Ricciardo’s benchmark. The top five was completed by Nico Hulkenberg, though the Renault driver had to pit before the end of the session with an unspecified problem.
The two McLarens were next, Singapore newcomer Stoffel Vandoorne ahead of Fernando Alonso, the latter being another of several drivers who brushed the wall during the 90 minutes.
Both Force Indias appeared in the top ten, separated by Kimi Raikkonen’s Ferrari. Carlos Sainz Jnr finished behind Vettel after twice going off into the turn 18 run-off.
Romain Grosjean endured a troubled session which included a couple of spins. He ended up 18th ahead of the two Saubers.
