Suspension System
Suspension SystemFront suspension is replaced by
monoshock absorber
SUSPENSION• Front suspension : shock absorber
• Rear suspension : • MacPherson strut suspension.
STEERING SHAFT ANALYSIS
STEERING SYSTEM• Steering system : adjusted rack
and pinion forsmooth and smaller turning radius.• Using front and rear disk brake
to improve the car brake for fast
stop.

Safety Design
DESIGN SAFETY CONSIDERATION
Double layer wall design with heat and sound insulation material:• Front layer made from fiberglass
• Back layer made from lightweight Al plate
Firewall as heat insulator
DESIGN SAFETY CONSIDERATION
Made from Square tube natural
silk fiber / epoxy composites with
high density foam.• Benefits:
• High impact energy absorption
• High strength• Lightweight
• Environmentally friendly
