Hangul

The Hangul is Taejo Togokahn's T-180 from the Speed Racer film, built by Togokahn Motors.

Technical Details
The Hangul is equipped with the standard auto-jacks that are installed on all T-180s in the WRL.

Distinguishing features include Togokahn's proprietary thermionic reciprocator, the powerful TM 9-71 engine, which outputs 567 dyne cm of torque for 29 bars of mean effective pressure, and a modified Kinginrin reverse helix exhaust port. To keep the wheelbase from breaking down from the immense horsepower, the joint system uses single-forged Bromium Hydrate wishbones.

Thunderhead
The vehicle is first seen very briefly in the beginning of Thunderhead. Although after the first jump, it is replaced by the Nosok T-180 for the remainder of the race. Taejo and his sponsor are also not listed in the placements.

Most likely, its appearance in that scene was an editing error.

Fuji Helexicon
In the Fuji Helexicon race, the car is wrecked after colliding with Billy Ray's Surge Box.

The Videogame
Taking place a year after the film, Speed Racer The Videogame features Taejo racing against Speed Racer and the other talented racers of the WRL on both the Console and DS versions of the game.

Console
In the console versions, the Hangul is unlocked upon beating Championship 1 of Class 2 (Pola Cola Cup). The car has average stats overall with focus on acceleration and lacking strength.

DS
In the DS version, the Hangul is unlocked upon amassing 600,000 fans, being the final unlockable car.
