Longitudinal member design in energy absorption zone: |
In the event of collision, impact upon occupants is lessened due to absorption of part of impact energy by the front section of this longitudinal member, especially in duration of secondary impact.
|
Steering tube design: |
Its peculiar four-cascade structure of energy absorption guarantees absorption of impact energy incurred in duration of collision, reduces the steering tube’s backward shifting, and accordingly lessens the collision’s harm to the driver to some extent.
|
Front/rear disc brake: |
The configuration of front/rear disc brake helps to arrange dual-circuit brake system in an effective way and furthermore, improve the reliability and safety of the brake system. Introduction of both front and rear disc brakes helps to stabilize braking power distribution rate and accordingly guarantee braking stability.
|
Front/rear multi-linked, all-independent suspension system: |
Such suspension system offers driving stability and occupant comfortableness. Carefully aligned five-link mechanism and shock-absorbing system help to minimize the shock from the ground surface to a comfortable extent, while guaranteeing accurate response to operations. The rear suspension’s self-tracking incurred upon high-speed swerving helps to lessen the over-steering tendency and avoid plumping into a dangerous driving status.
|
Fuel cutoff switch: |
In the event of collision, the fuel cutoff switch cuts off fuel supply by disconnecting the fuel pump’s connection with the earth, meanwhile unlocking the central door locking system and switching on the interior lamps and exterior telltale lamps, so as to avoid secondary harms as possible as could.
