Ayumi Kan street cars

The KaraSugoi street cars are two of the various background vehicles featured in the Casa Cristo 5000 race from the Speed Racer film.

Technical Details
As mentioned in the Supercharged featurette, KaraSugoi is the company responsible for making the 26-cylinder hotblock used in Grey Ghost's race car, the Fumée, meaning it is very likely that these cars also use this component.

Background
The two KaraSugoi cars can be seen at the start of the Casa Cristo race; One that has a yellow, white and blue livery and the other is white, red and pink. It is unknown if they make it past the first part as they do not appear in subsequent scenes.

Trivia

 * There exists concept art for a T-180 version of a KaraSugoi car, although it likely does not appear in the film itself.
 * This car has the same body shape as the Calomay Fiber T-180.
 * It also has the same body shape as an earlier design for the Hydra-Cell street car seen in the U.B. Funkeys game.
