KATANA

LIGHTWEIGHT COUPE

FR · REAR WHEEL DRIVE

Twitchy and fast to rotate. Snap oversteer on entry, unforgiving if you ignore the countersteer window. High risk, high reward.

AWD · ATTESSA SYSTEM

Heavy, planted, powerful. ATTESSA torque transfer fights your drift. Commit hard to break it loose — when it slides it stays stable.

FRONT WHEEL DRIVE

FF · FRONT WHEEL DRIVE

Shouldn't drift. Does. Throttle pushes to understeer — use the handbrake and weight transfer. Scandinavian flick is your entry. Rewarding to master.

FIGURE EIGHT

GLB TRACK · CROSSOVER LAYOUT

Intersecting loops with a centre crossover. The crossing point is where it gets real — manage your speed or meet someone coming the other way.

OVAL

PROCEDURAL · CLOSED LOOP

Clean symmetrical oval with red-white curbs and barriers. No GLB required — built at runtime. Great for learning car behaviour and chasing clean laps.
