Ferrari team principal Maurizio Arrivabene has revealed that he asked the design team to build this season's car with Kimi Raikkonen in mind.
The Finn endured a miserable season last year with a car which wasn't suited to his driving style, but he has hit back so far this season and came second in the Bahrain Grand Prix.
Arrivabene told reporters: "I remember it was 10th or 12th December, I was speaking to [chief designer Simone] Resta and Rory [Byrne] and we were watching a picture of the car. I asked what can you do to transfer weight a bit more to the front?
"Because I said Kimi likes to feel the car this way and Sebastian [Vettel] is more or less the same. They said we need six months. I said what can you do in three?
"They said we need to work more or less day and night so I said OK, I will work together with you guys. Come on."
Raikkonen sits fourth in the drivers' standings.
