The track layout was just released:
The 3.4-mile track has 20 turns, a maximum elevation change of 133 feet, a back straightaway that is three-quarters of a mile long and a width that will vary between 39 and 52 feet.
Hellmund said Turn 1 could be the circuit's signature corner and that it would also be one of the four designed spots to give drivers their best chance for passing
He said the best way to create such opportunities is with a good straightaway that leads to a turn with more than a 90-degree angle. Hellmund said that's the plan for turns 11, 12 and 20.
In addition, turns 3, 4, 5 and 6 and will be a nod to the Maggots/Becketts section at Silverstone in England, and turns 12, 13, 14 and 15 will have the feel of the Hockenheimring in Germany.
There's also a shout-out to Istanbul Turn 8 in turns 16, 17 and 18.
