Sauber technical director James Key admitted that the team's car was not quick enough to stay in contention for a podium finish in the Canadian Grand Prix once the track dried
Kamui Kobayashi ran second in the wet part of the race, but faded to seventh at the finish as conditions improved.
"Kamui did well to make a bit of progress initially, and we felt the race pace could be better because we'd been on higher downforce all weekend - anticipating weather conditions to a certain extent," Key told AUTOSPORT. "He did pretty well in the wet and actually we were quite competitive.
"Unfortunately we were in a situation where we couldn't use the DRS because we were at the front of the back, and our straightline speed wasn't good because we were on the higher downforce level. We never really got an opportunity to have a go back.
"Our dry pace wasn't very good here, and I think when the dry tyres came in, we suffered a bit. On the dries, it hasn't been our track, so we lost out."
Key said he never had high hopes for Montreal, but still found the degree to which Sauber struggled in the dry a disappointment.
"It could've been worse," he said. "The pace was disappointing in the dry.
"We kind of know what it is - it's a combination of things. But it was a bit worse than I thought it would be here. It's not our track at all.
"So to come out with a seventh place, we can't complain at all. It's just that it could have been a bit higher if things had worked in our favour in the race."
Yuki Tsunoda arrived in grand prix racing amid a whirlwind of hype, which only increased after his first race impressed the biggest wigs in Formula 1. His road since has been rocky and crash-filled, and OLEG KARPOV asks why Red Bull maintains faith in a driver who admits he isn’t really that big a fan of F1?
OPINION: After Lewis Hamilton responded to reports labelling him 'furious' with Mercedes following his heated exchanges over team radio during the Russian Grand Prix, it provided a snapshot on how Formula 1 broadcasting radio snippets can both illuminate and misrepresent the true situation
OPINION: Valtteri Bottas is credited with pole position for the 2021 Turkish Grand Prix, despite being beaten in qualifying. This is another example of Formula 1 and the FIA scoring an own goal by forgetting what makes motorsport magic, with the Istanbul race winner also a victim of this in the championship’s recent history
Starting 11th after his engine change grid penalty, Lewis Hamilton faced a tough task to repeat his Turkish Grand Prix heroics of 2020 - despite making strong early progress in the wet. Instead, his Mercedes team-mate Valtteri Bottas broke through for a first win of the year to mitigate Max Verstappen re-taking the points lead
Mercedes and Lewis Hamilton dominated the opening day of action for the 2021 Turkish Grand Prix, on the Istanbul circuit’s much improved track surface. But the Black Arrows squad’s position isn’t quite what it seems. Here’s why
On 8 October 1961, Innes Ireland claimed victory at the United States Grand Prix to herald the true arrival of a new Formula 1 giant. While Team Lotus endured plenty of highs and lows until the team folded over three decades later, Colin Chapman's squad made F1 history and helped shape the championship
