Question 1

Chassis - Tubular Backbone

Answer

Developed for road and track use, the backbone design cloaks the power train and accurately locates the suspension for excellent power delivery with positive and precise control. Designed for huge V8 power the chassis always feel taut and responsive when pushed to the limit.

Question 2

Body shell - GRP Semi-Monocoque

Answer

Quite unlike conventional body shells the GD body shell is a one-piece rigid semi-monocoque (tub) design with double skin mouldings. A composite construction made of glass fibre reinforced plastic with critical areas strengthened with advanced woven glass materials. The tub rigidity is enhanced with front and rear bulkheads, engine bay, foot-wells, transmission tunnel and all inner mouldings as an integral part of the structure. Further occupancy protection is gained by injecting energy absorbing polyurethane foam into the body sides and the use of sliding anti-intrusion beams within the doors. The body tub is insulated from the chassis with anti-vibration mounts adding further comfort and longevity.

Question 3

Suspension - Double Wishbone

Answer

The chassis features independent double wishbone suspension with aircraft grade alloy uprights. Compared to conventional designs the suspension offers lighter unsprung weight and provides better camber control with adjustment for static camber, caster and toe-in settings. The suspension design gives the GD unrivalled levels of road holding and ride quality.
