Turn 2
Turn 2 is a right-hander, turning through about 159°. Turn 2 comes 805 m after T1, and T3 follows 165 m later.
- Tony D’Alberto: The longer straight into Turn 2 makes it the main overtaking spot on the extended layout. (Speedcafe)
- Richard Moore: Turn 2 is where the passing happens; through the rest of the new section the field tends to run nose to tail. (Driven / NZME)
Turn 4
Turn 4 is a right-hander, turning through about 132°. Turn 4 comes 210 m after T3, and T5 follows 135 m later. Turn 4 is the first apex of a double-apex right-hander that turns through about 208° in all, and T5 is the second.
Turn 5
Turn 5 is a roughly right-angle right-hander, turning through about 76°. Turn 5 comes 135 m after T4, and T6 follows 270 m later. Turn 5 is the second apex of that double-apex right-hander, after T4.
Turn 6
Turn 6 is an open left-hander, turning through about 72°. Turn 6 comes 270 m after T5, and T7 follows 160 m later. Turn 6 is the first apex of a double-apex left-hander that turns through about 201° in all, and T7 is the second.
- Richard Moore: A tight, technical double-apex left that takes time to work out; expect to keep refining your line through both apexes. (Driven / NZME)
Turn 7
Turn 7 is a left-hander, turning through about 129°. Turn 7 comes 160 m after T6, and T8 follows 195 m later. Turn 7 is the second apex of that double-apex left-hander, after T6.
