HOLDEN says that rearward of its A-pillar, Monaro's body structure is unique, featuring some 84 major new body panels. Its two-door body is actually more taut than regular Commodore sedans - bending stiffness is increased by 23 per cent and torsional stiffness by five per cent. The differentiation between Monaro and Commodore is assured by the fact that only the bonnet and front guards are interchangeable - even the windscreen rakes back at a two-degrees-steeper angle - while the tighter, stubbier look is enhanced by the fact that rear overhang has been reduced by 100mm. The doors are 150mm longer, meaning the B-pillar is moved rearward by the same margin, while the roof is 40mm lower and the aerodynamic drag co-efficient rates at 0.31 Cd.
