So what's the difference ? I don't know about Maseratis, but Astons are a tube spaceframe clad with aluminium. The aluminium panels aren't load-bearing (i.e. it's still a spaceframe structurally, not a monocoque). Is superleggera a stressed panel method, and is it inaccurate to describe Astons as using it ?
(It's also a real sod for galvanic corrosion where the panels touch the tubes)
