Sumiya T-180

The Ki-goi car has two liveries blue for the Grand Prix and red for Thunderhead

The red form can be seen in a few shots and has a kinda fish scale pattern but is usually around the end of the pack.

The Blue Version is seen in The Grand Prix starting line in one of the First three rows but is not seen until the big drop in the background. It is also seen passing speed when both the Mach 6 and GRX crash. Lastly it’s seen being passed by speed in the halfpipe and just nearly avoiding the flying Kasatoshi car before it got wrecked.
