Lewis Hamilton says Mercedes solved its 2020 car – the W11’s one weakness, more precisely its problems with corner rotation.
For the latest rules phase Mercedes decided to have a longer wheelbase than other teams. While the manufacturer believes this was the right choice due to improved downforce, the car also has a weakness related to car rotation in corners.
“With last year’s car for example, we had the longest car,” Lewis Hamilton said in an interview with motorsport.com.
“It’s definitely been a bit of a surprise to see that none of the other teams have gone to the longest car.
“We’ve been winning with the longest car since 2017, and they [other teams] are so stuck in the way they do things, in that ‘we’re still going to keep our car shorter.’
“Being that it’s a long car, it’s obviously got great downforce, but it’s not as nimble as a shorter car. Last year our car was good through medium and high-speed corners, but was quite poor in low-speed corners. The car would not rotate as well as we’d like.
“We started this year in winter testing and the car had similar characteristics. I had some challenges that I put towards the team in terms of how we set the car up, which changed that.
“It’s difficult to say too much, but that difficulty we had last year with the car rotating, we don’t have that problem anymore.”

The Briton goes on to say he always prefers a more responsive front end of the car and Mercedes ultimately managed to mitigate the problem.
“I’ve always preferred a more positive front end in the car. But there’s a limitation with these tyres. The front has a limitation, the rear has a limitation, grip wise.
“There’s saturation, there’s thermal deg and there’s only a certain amount you can do with the mechanical balance before it affects the other end. It’s like a see-saw.
“Last year our car was definitely very, very strong at the rear, and the car was generally driven by the rear end. The front was a lot more understeery last year.
“You struggled a lot more when you go over the tyre [grip] and no matter how much we put the mechanical rearwards it wouldn’t really fix it. This year we have made some changes.
“With the aero balance it’s a much longer process. You can’t just change it. Definitely over the winter we fixed it and moved the aero balance more rearwards, so the car was shifting different, and also at different steering angles and different yaw.
“So it definitely is working a lot better,” concluded Hamilton.
