Sainz "confused" over issues which impacted his qualifying last season

Carlos Sainz is still "confused" about an instability issue he had at Renault which impacted his ability to score quick times in qualifying sessions.

Sainz has now left Renault but still does not know what caused the instability problems. The McLaren driver said to Motorsport.com, "when it comes to finding the limits of the Renault car, it was where I tend to struggle a bit."

Sainz has said that the instability problem first came about early in the season and found that trying to fix the problem resulted in a loss of speed.

Sainz has now moved to McLaren and will hope that he can push the car to its maximum in order to score better results in qualifying.
