Former F1 ace Alex Wurz gives the lowdown on the notoriously tricky Istanbul circuit that hosts this weekend's Turkish Grand Prix.
Istanbul Park is a challenging track from a set-up point of view because of the variation in corner speeds and grip levels.
There are the very fast changes in direction at the start of the lap, there's a long straight and then some slower stuff at the end of the lap, which makes set-up a compromise.
The asphalt also changes a lot around the lap: it feels very slippery in the last sector and then you have a lot of grip in the first sector.
People talk a lot about the long turn eight. For me, it's just bumpy and a neck-killer; it's not a place where going haywire gives you a lot of lap-time because that's never the case in fast corners.
Our minimum apex speed is about 155mph, and if you get it right, the biggest reward you have is showing the data to your engineer. The flip side of going too hard through here is that you might destroy your right-front tyre over a long stint.
For me, the biggest challenge of Turkey - apart from the traffic going into Istanbul - is the last section of the lap. The last three corners are very slow, all about 50mph in second gear, and they're all inter-linked.
If you make a tiny mistake under braking for the third-to-last corner, your track position for the entire complex is wrong, and that can affect your speed as you accelerate onto the start-finish straight. You also have to be disciplined because it's very easy to over-drive.
Istanbul itself is a cool city. I've been there a few times and there are amazing places to go out, and great things to see.
The Bosphorus is spectacular; if you're going to the race, you should make a point of looking at it and feeling its history.
