2014 Chinese GP: Ferrari Formula One F1 Practice Recap

2014 Chinese GP: Ferrari Formula One F1 Practice Recap


Weather will have a big effect on tyre behaviour throughout the Chinese Grand Prix weekend, with free practice today characterised by cool weather and a possibility of rain for qualifying tomorrow. Ambient and track temperatures dipped to 13 and 15 degrees centigrade respectively during FP1 this morning, before becoming slightly warmer in the afternoon.

As a result, the drivers had to be sure of warming their tyres up properly, in order to extract the best possible performance and guard against graining. In order to warm up the compound, the driver has to gradually put more heat and energy into the tyre during the out lap, so that the compound reacts with the surface to generate grip. Graining happens when the tyre simply skates across the asphalt rather than bonding with it, causing wave-like patterns of wear across the surface of the tread. Graining was seen for some drivers during free practice, but it remained within anticipated levels.

Paul Hembery: "We’ve seen quite a big gap in terms of lap time between the two compounds today: between 1.4 seconds and 1.8 seconds depending on the team. These are exceptional circumstances because temperatures are a lot cooler than we would expect to see over the rest of the season, and with rain expected tomorrow, weather will obviously remain a big factor over the course of this weekend. There’s been some graining, but no more than we would expect under these circumstances. We’ll analyse all the data tonight but so far we would expect the teams to get about 20 laps out of a set of soft tyres and approximately 25 laps out of a set of mediums. Degradation on the medium tyres is
about half of what we are seeing on the soft tyres: in terms of performance the medium tyre loses about 0.15 seconds per lap in race trim, whereas the soft tyre loses about 0.3 seconds per lap. We’re looking at between two and three pit stops on Sunday from what we can see so far."

FP1: FP2:

Alonso 1m39.783s - Medium New Hamilton 1m38.315s - Soft New

Rosberg 1m40.181s - Medium Used Alonso 1m38.456s - Soft New

Ricciardo 1m40.772s - Medium New Rosberg 1m38.726s - Soft New

Tyre statistics of the day:

Medium Soft Intermediate Wet

kms driven * 3,722 1,744 N/A N/A

sets used overall ** 65 22 N/A N/A

highest number of laps ** 27 22 N/A N/A

* The above number gives the total amount of kilometres driven in FP1 and FP2 today, all drivers combined.

** Per compound, all drivers combined.
