Drivetrain layout
Map engine and transmission mounts, driveshaft clearance, cooling airflow and service access before locking in the chassis layout.
A Honda-powered Ultra4 buggy in development. The K20C4 turbo and 10-speed automatic set the packaging requirements for a purpose-built chassis.

Development targets are subject to design review, fabrication and testing. Vehicle renderings show the intended direction.
The Yamaha YXZ 4S Build is where we work through front axle geometry, driveshaft movement and hydraulic steering clearance. We’re carrying those checks into EVO 2.0T mock-up, where the new chassis and powertrain layout will have their own measurements.

Check shock placement, spring clearance and suspension movement through bump, droop and steering lock.
Plan shakedown checks for steering, braking, cooling and driveline behavior before increasing test loads.
