As the Singapore GP approaches, Formula 1 champion Nico Rosberg offers insights into the unique challenges drivers endure during the race. Drawing from his own experience on the circuit, Rosberg vividly explained the intense heat drivers endure while navigating through one of the longest and most demanding circuits on the Formula 1 calendar.
In 2008, the Singapore Grand Prix debuted at the Marina Bay Street Circuit, and since then, it has established itself as one of the most important tracks on the Formula 1 calendar. In contrast to the Monaco Grand Prix, the Singapore Grand Prix maintains a full race distance of over 305 kilometers, resulting in a race duration of about 2 hours. One of the biggest challenges is the weight loss the drivers experience during the race.
During a recent interview on the Sky Sports F1 podcast, Rosberg highlighted the challenges he encountered as a driver in the Singapore circuit. He particularly emphasized the potential weight loss drivers experience due to the high temperature during the race.
“I would lose eight pounds of bodyweight from sweating…You can carbon seat moulded to your body so you can hardly breathe properly…It’s like you are in a sauna on a spinning bike for two hours,” concluded Nico Rosberg

The Marina Bay Circuit has undergone construction, which resulted in the removal of many 90-degree corners at the end of this year’s Singapore Grand Prix lap. These renovations are anticipated to significantly improve tire degradation and various other aspects of the race.
As a result of the reconstruction, many teams have expressed their interests and concerns about the situation. Additionally, numerous drivers have recognized the newly added turn 16 as an important opportunity to enhance their position during the race.
“That was very, very good news…Hopefully [it will help] overtaking, which was impossible before….I’m pretty sure we’re going to be able to get closer behind, and that’s going to change a lot of things,” said Alpine driver Esteban Ocon about the new overtaking opportunity, as reported by motorsports.com
The faster lap times and quicker ends to laps reduced the chances for the team to make early decisions. Dave Robson, Williams’ head of vehicle performance, indicated that the track revisions may not negatively impact the team.
