Cosmopolis Grand Prix

The Cosmopolis Grand Prix is a racing track featured in the Speed Racer film (and the tie-in video game).

Background
It is one of many race courses sanctioned by the WRL. Located on the center of Cosmopolis inside a massive colosseum, the track uses advanced resins to support the cars in near-impossible positions and is tweaked every year to keep ahead of evolving technologies.

This is where the final race of the film takes place in, where Speed Racer goes against Jack "Cannonball" Taylor and many other famous drivers.

Starting Grid
The starting grid has a checker-patterned floor and surrounded by grandstands with all kinds of sponsors. The cars are parked in a three-two-three-two layout, and ahead of them is a massive screen, where the countdown girl appears.

Winding Road
Directly after the starting grid, cars are greeted with a winding road which eventually leads to the Zebra Halls.

Zebra Halls
The Zebra Halls are named such as the walls have black and white paintings of zebras, each being a frame of their movement. While the cars race through this wide and long straightway, the zebras appear to be running alongside them.

Banked Turn 1
At the end of the Zebra Halls, cars are to turn while on the wall, eventually leading back to a flat road. This road eventually leads to the Moguls.

The Moguls
The Moguls refer to a bumpy long road.

Banked Turn 2
At the end of the Moguls, there's another banked turn. This turn has advertisements playing on the track while the cars drives over it. The turn leads to the Half-pipe.

Half-pipe
This section is composed of a long straight and a right turn in the form of a spiked Half-pipe.

Helix Tower
The Helix Tower is a series of right turns going up until it forms a cyclone-like tower.

The Big Drop
The Drift Tower eventually ends in a track that almost goes straight down, being a huge drop in which most cars tend to race carefully on.

The Big Bank
At the bottom there's a colossal banked turn with kanji on it going to the left, leading to a long straightway.

Grandstands Straightway
This is a long straightway with grandstands on both sides.
