11. Interior Design

12. Suspension System

13. SUSPENSION
•Front suspension : shock absorber
•Rear suspension :
•MacPherson strut suspension.
Front suspension is replaced by
Suspension System
monoshock absorber

14. STEERING SYSTEM
• Steering system : adjusted rack and
pinion for
smooth and smaller turning radius.
• Using front and rear disk brake to
improve the car brake for fast stop.
