Valterri Bottas' maiden Singapore Grand Prix outing proved a demanding affair for the Williams driver, and not just because of the hot and humid conditions and the testing nature of the tight and twisting 3.152-mile, 23-turn street course in Marina Bay.
"It was one of the most difficult races of the whole season for me," admitted the 24-year-old Finn after stating from 16th place on the grid for Sunday's race.
"Immediately at the start we had a problem with the clutch which meant we lost a few positions," he explained. "After the safety car we had a few problems with debris in the front wing, which made the car difficult to drive.
"These limiting factors meant we couldn't go any faster today and so we did the best we could with what we had," he summed up after coming home in 13th place at the chequered flag.
"Valtteri was unable to hold position at the start due to a clutch problem and consequently struggled with his tyres fighting to regain position," confirmed Williams F1's chief race engineer Xevi Pujolar. "Valtteri's race was further compromised by debris in his front wing meaning he didn't have the pace to challenge for position."
By contrast, his team mate Pastor Maldonado had a solid workmanlike day looking after his tyres - not the most exciting day at the office but still enough to raise him up from a disappointing 18th in qualifying to 11th place just one position off the points by the end of the race itself on Sunday.
"We recovered two places at the start and after a couple of laps we were pushing towards the cars in front whilst also trying to manage the rear tyres," he explained. "My tyre management was good throughout the race and I was able to push hard in the final stages on the supersoft tyres.
"We just missed out on points in the end, but we'll be looking to progress a step further in the next race," he added.
"Pastor had a good start, gaining a few positions and managing his tyres well in the early stages," contributed Pujolar. "Under the safety car we pitted both cars for their second stops to move onto the prime medium tyre. We were looking at the data to see if we could go to the end but when it became clear that we needed to stop again we switched both cars back onto supersofts.
"Pastor was then able to fight to the end gaining two positions in the final stages to finish P11," Pujolar said. "Both Pastor and Valtteri drove a solid race today in challenging conditions but we need to find more performance from the car if we want to be consistently fighting for points."
