Former Williams F1 driver David Coulthard refers to Istanbul Park as "a modern day classic". The track undulates and it has several fast corners, which require aerodynamic performance from the cars and commitment from the drivers.

The most challenging corner on the lap is the quadruple-apex Turn 8, through which the drivers pull 5G for nearly seven seconds. The entry to the corner is blind and there's a bump mid-corner that tries to throw the cars off-line.Being the first of only five anti-clockwise circuits on the calendar, it's a physical track for the drivers because the left side of the neck takes a pounding. "As long as you put the necessary work in beforehand, you're okay," says AT&T Williams driver RubensBarrichello. "However fit you are, though, you'll begin to feel your neck by the end of this race. It's tough."

Rubens Barrichello: I want to have a more competitive weekend with the team than we have had so far this season. We have new parts coming for Turkey which will hopefully work in our favour. I love Istanbul Park. It is one of the most challenging circuits on the calendar and we will aim to be flat out there. Everyone says Turn 8 is a highlight, and it is, but I also find the circuit nice from a set-up point of view with qualifying also a good challenge. I like the track as a whole.

Pastor Maldonado: I've been to Istanbul Park four or five times and I think it is a good circuit to race on. Last year I had one of my best races of the season in Istanbul racing in GP2. If we can get the car performing as we want to this weekend, it will be a good event for us. Turn 8 is my favourite part of the circuit as it is an amazing, very long and fast corner. It is also quite a technical circuit. We are improving and I hope we can jump forward with the upgrades we have here and be more competitive.

Sam Michael, Technical Director: We're bringing a number of upgrades to the FW33 over the next few races, starting with Istanbul. The package for Turkey will include new brake ducts, revised front wing and rear wings, plus some other secondary items. Combined, these components should give the FW33 a decent step-up in performance. Our objective is to get the car into the points as soon as possible.

Istanbul Park has a great layout for the drivers to get their teeth into. In particular, it boasts an excellent natural overtaking spot at the end of the back straight. Turkey has the notorious Turn 8, a left-hander which places considerable loads on the car's aerodynamics. A car that can handle those pressures, combined with one capable of some significant kerb riding through the last sequence of corners, is critical at this track.
