Renault's Jenson Button drives a lap of the Indianapolis F1 circuit:
"I approach the first corner at the maximum speed I reach on the circuit, which is around 325 km/h, obviously in top gear."

"The first right-hand corner is quite tight, and I have to brake very hard in order to get my speed down to around 115 km/h, and drop down to 2nd gear. I hold 2nd gear through turn 2, but am able to increase my speed to about 130 km/h."

"Turn 3 is actually taken flat and presents no problems: I will apex in 3rd gear at 190 km/h."

"Turn 4 is extremely difficult, as I will approach it in 4th gear at 240 km/h but need to brake deep into the corner with a lot of lateral acceleration on the car, getting down to 135 km/h in second gear. I need to be very careful not to lock the inside front wheel under braking for this corner."

"Exiting turn 4, I can quite easily take turn 5 flat, at between 240 and 255 km/h in 4th gear. I actually reach 265 km/h, still in 4th gear, before approaching the very long turn 6."

"This is taken in 2nd gear at around 120 km/h, but it is an extremely long corner through which I will be experiencing over 2g lateral acceleration for around five seconds."

"Before turn 7, I will only just reach full throttle at approximately 170 km/h before braking again, and going through this turn at around 110 km/h. I will be looking for a clean exit onto the back straight, along which I will reach just over 300 km/h in 5th gear before going into the next, very tight part of the circuit."

"At the end of the straight, I will need to drop down to around 105 km/h in 2nd gear for turn 8, and will briefly touch 150 km/h in second gear before turn 9. This is the tightest corner on the circuit, and I will take it in 1st gear, apexing at just 60 km/h."

"I can hold 1st gear right up to turn 10, reaching around 100 km/h and then dropping back to just under 70 km/h for the corner itself."

"The short straight leading to turn 11 will see me in 3rd gear, at around 210 km/h, before braking for the corner, which I will take in 2nd gear at 135 km/h."

"The exit of turn 11 is the most critical part of the circuit, as it leads back onto the speedway section, which although it contains two corners is taken flat out. The first of these I will take in 4th gear at 250 km/h and accelerate all the way through, exiting in 5th gear at 295 km/h. The final corner, which is steeply banked, will see me in 6th gear at around 315 km/h before coming back to the pit straight."

"I am completely flat on the throttle from the exit of turn 11 right through to turn 1: this represents over 22 seconds of full-throttle running, which, along with the run from La Source to Les Combes at Spa, is the longest of any circuit we go to."
