Ferrari has again decided not to use its most recent upgrade package in this weekend’s Mexican Grand Prix after testing it back-to-back with a previous specification.Sebastian Vettel and Kimi Raikkonen ran the two different versions in practice at the Autodromo Hermanos Rodriguez today. Afterwards Vettel told media: “We’re sticking to the old package.”
At the previous race in Austin, Vettel said the team became more competitive because it removed “three or fourth months” worth of upgrades from its car.
Vettel ended the second practice session behind both Red Bulls and, unusually, Carlos Sainz Jnr’s Renault. He admitted Ferrari hasn’t got the best out of its car over a single lap yet.
“I think in the long run it’s not too bad but for one lap we’re struggling quite a bit to get the balance right and squeeze everything out of the tyres.”
“The difficulty is that you don’t have any grip so we’re sliding a lot. And the problem is if you don’t have a lot of grip and downforce because the air is so thin you don’t get the tyres to work.
“When the tyres don’t work it’s really tricky. That’s why you can see quite big jumps in lap time. If you don’t get it right you’re quite far off the pace.
“I think that will be the main job to get right for tomorrow because you have one lap in quali. I think with the hyper-soft it should be a bit easier but still it’s tricky to keep a clean balance from the beginning to the end of the lap.”
