Page 1 | Page 2 The new WH Grange is the result of the most comprehensive development program for any HSV long wheelbase model. The prospect of healthy export orders has encouraged HSV to allocate extra resources to position the new WH Grange further away from mainstream Holden long wheelbase models and other models in the HSV range. The WH Grange introduces an exciting and different approach to high performance long wheelbase luxury and style. The sleek, low profile of Holden’s new WH long wheelbase range provided the ideal starting point for HSV to redefine the Grange combination of driver involvement and spacious luxury accommodation. Grange buyers now have the choice of the proven supercharged V6 or the new LS1 5.7 V8. For those luxury buyers who require an efficient and effortless six cylinder engine, HSV’s supercharged V6 offers 180 kW and a solid wall of torque and is available to special order. For those who prefer the immense reserves of a potent V8, the 250 kW HSV version of the new Chevrolet LS1 V8 introduces a sophisticated free-revving feel while adding another performance dimension to Grange luxury motoring. The exterior styling has been the focus of the most spectacular changes. For the first time, HSV has been able to comprehensively re-style the front and rear sections of a Holden Long wheelbase model. Ian Callum from HSV’s TWR parent company has given the WH Grange a lower, more disciplined look that sets it apart from traditional large Australian luxury cars and positions it aggressively as a more affordable alternative to the best European and Japanese luxury models. The front and rear bumper sections unique to the Grange combined with the deep side skirts, change the profile of the Grange and leave it with a squat, ground hugging stance that belies its size. At the front, Ian Callum has given the WH Grange a bold new look. The challenge was to develop a distinctive identity that moved the new model into a luxury niche clear of HSV’s elite Senator Signature range. Drawing on a tradition established by sporting Bentley sedans, the WH Grange has its own chrome grille profile filled with chrome mesh, a theme that is repeated in the lower air intake. The new grille with its large centre emblem leaves the bonnet free of ornamentation to emphasise the raised centre bonnet section which in turn reinforces the muscle-bound nature of the new model. HSV has gone to considerable lengths to keep the exterior detailing simple and elegant. The flush front fog light profile is unique to the Grange while the boot lid spoiler also exclusive to the Grange is more subtle than usual in a car with this much performance. The way that the exhaust tip is contoured to match the sweep of the rear bumper is indicative of the attention to detail. Badgework is classy and restrained. The unusual 10 spoke 18 inch alloy wheels have a substantial, structural look for visual balance, the perfect match for a large and powerful luxury package. The WH Grange’s look of potent luxury is reinforced by a new HSV suspension level. Initially, HSV intended to draw on the chassis development from the standard wheelbase VT models but it soon became apparent that a fresh approach specific to the new long wheelbase model was required. The brief was to retain the smooth, limousine like qualities that remain a pre-requisite for long wheelbase luxury motoring while injecting new levels of driver involvement and excitement. The big increase in the body stiffness of Holden’s new WH wheelbase platform dictates fewer compromises. The result was HSV’s new prestige suspension. The starting point was the grippy Bridgestone S02 18 inch tyres specifically designed for the VT GTS. The suspension was then tuned to exploit their extra grip while retaining the comfort levels and driving effort expected in a benchmark luxury car. Specific HSV springs included heavier rear springs tuned for the extra rear weight bias of the long wheelbase platform. Monroe Sensatrac dampers were specifically developed for the WH Grange application with firmer valving than the Senator to provide extra control under more extreme conditions while offering initial compliance for a smooth, luxury ride. Standard rear self-leveling maintains this control regardless of load, essential in a long wheelbase model where the rear seat comfort is as important as the front. Page 1 | Page 2 |
