Jarno Trulli's lap of Suzuka.

Mild Seven Renault F1 driver Jarno Trulli describes a lap of Suzuka, venue for this weekend's Japanese Grand Prix:

"Approaching Turn 1, I will be at the maximum speed that we generally see at this circuit although it is slightly dependent on wind: this is typically 320 kph. Turn 1 is very fast and I just drop to 5th gear, braking quite lightly to take the corner at 250 kph. Turn 2 requires much heavier braking as I must go down to 3rd and 150 kph."

"Exiting Turn 2 leads me into the very tricky section behind the pits which consists of a number of continuous left-right corners which require a very smooth style and a finely balanced car."

"The first of these, Turn 3, is approached with very light braking as I take it in 4th gear at 225 kph. I am almost immediately turning right into Turn 4, again with a light touch on the brakes to slow to 185 kph, before holding 4th gear for Turn 5, which is taken at approximately 200 kph. Turn 6 is a little trickier in that it is almost two corners, which I take at approximately 170 kph, this time in 3rd gear. Turn 7, the final corner in this sequence, is approached at 230 kph and I can actually turn into this corner without braking, just slightly scrubbing speed to apex at 205 kph in 4th gear."

"Approaching Turn 8, I will get up to 290 kph in top before having to brake very hard and change back down to 4th gear to take the corner at 210 kph. Turn 9 is much tighter and I will take it in 2nd gear at approximately 130 kph."

"Passing under the bridge, I will approach the hairpin at 270 kph in 5th gear. Braking for this corner is quite difficult as I have to shed almost 200 kph but as I enter the braking zone, there is still a lot of lateral force on the car from the small kink that precedes the corner. The hairpin itself is taken in 1st gear at 70 kph."

"Turn 12 is an extremely long corner but taken completely flat out. I will enter it at 180 kph in 3rd gear and exit at 295 kph. The loads are high enough that the car tends to bog down through the corner, meaning the approach to Turn 13 will only see me at 300 kph."

"Turn 13 is a 4th gear, 200 kph which has an important exit in order to get the right line for Turn 14, which I must take in 3rd gear at 150kph."

"Approaching Turn 15, I should reach 315 kph in top gear for this very fast, quite bumpy corner that I will take at approximately 290 kph."

"Leading up to the chicane, my speed will have built up again to 385 kph before braking hard for this complex, both parts of which are taken in 1st gear at 65 kph. I need to use the kerbs here and therefore require good ride from the car."

"The final corner is in fact flat and I accelerate through it, exiting at approximately 270 kph in 5th gear, crossing the line in top at around 310 kph."
