Pulled up some interesting info on the coupe 4 setup…
The mammoth task of actually developing Australia’s first low ride height AWD coupé has proven to be an engineering triumph for the relatively small, close-knit HSV development team.
“Lowering the ride height (from Avalanche wagon) changed the entire geometry of the front suspension – the roll centre, camber, toe settings, etc”, says HSV AWD Engineering Program Manager, Joel Stoddart.
“Correcting that meant designing a totally new lower control arm and steering knuckle assembly.
“At the rear it was a matter of fitting a current Coupé semi trailing arm and switching to 19 X 9-inch rear wheels (front are 19 X 8-inch) with a unique offset to maintain the correct wheel track,” commented Stoddart
As the low-ride version of Holden’s all-wheel drive system it uses different suspension components and geometry to the high-riding Adventra and Crewman off-roaders.
