Felipe Nasr felt he had a productive day at the Marina Bay Street Circuit on Friday as he continued to gather data with the aero package his Sauber F1 Team have been running in recent races.
The Brazilian finished fifteenth in the first session, before taking eighteenth in the second session under the floodlights in Singapore, but Nasr feels the team still have work to do to improve ahead of Saturday’s running.
“It was a productive day,” said Nasr. “In FP1 we continued our evaluation of the aero package, as we were running a high downforce configuration for the first time.
“It was good to collect data and to get a feeling for the balance of the car. For the rest of the weekend we still have some work to do in terms of the set-up of the car.”
Team-mate Marcus Ericsson finished both sessions in twentieth position, and suffered power unit problems during the opening session that necessitated a change of engine in between FP1 and FP2, while the Swede also struggled to get the balance right with the Ultrasoft compared to the Supersoft.
“It has been a difficult day,” admitted Ericsson. “In FP1 I struggled with the car due to power unit issues, so we decided to change the engine for FP2.
“In this session I had a good feeling on the Supersoft tyres, but for some reason on the Ultrasoft compound I struggled to get them to work. So far we do not understand why that was the case, so we need to look into it and analyse what happened.”
