Grosjean: “Performance drops suddenly”

Romain Grosjean completed a productive test session this Tuesday in Abu Dhabi. The pilot Haas was the most diligent on the Yas Marina track with 137 laps covered and finished with the fourth fastest time to his name.

The former GP2 champion was able to compare the tires from the 2018 season with those used this year. Contrary to Kimi Räikkönen, the Frenchman noted significant differences.

“It was a very productive day, confirmed Romain Grosjean. We have reviewed the range from mediums to hypersofts. These are excellent, they will make excellent qualifying tires. On the other hand, their lifespan is shortened at the moment. »

“There is a gain on all types of rubber tried, but the problem is that performance drops suddenly. Degradation is good up to a point and, beyond that point, it's a fall.", underlined the Frenchman.
