Chassis and powertrain systems are essential for vehicle dynamics, safety and comfort. Chassis components provide structural stability and strength, and absorb some of the shock of an accident, while contributing to the vehicle structure. Suspension and steering provide stability, comfort and handling on various surfaces. Brakes provide safety, deceleration and stopping ability. Power delivery to the wheels for efficiency and control is managed by the drivetrain and transmission components. Components of the engine are connected with the combustion, performance and efficiency in combustion engines. Handling, ride and comfort are improved with wheels, tires and NVH (noise, vibration and harshness) components.
