	The VVA platform, as used in the [[:Category:Lotus Evora\|Lotus Evora]], uses the same technique of extruding and bonding aluminium, and is designed to be easily customised to suit different sized low and mid-volume vehicles up to 1,900kg by altering the length and thickness of various extrusions.

	~~Key~~ differences to the Elise chassis in the Evoras VVA implementation ~~include that the rear subframe~~ is ~~made from aluminium, as opposed to steel on~~ the ~~Elise chassis designs, and~~ removable front sub-frame which carries the front suspension mounts and allows the sub-frame to be replaced in the event of an accident which damages the front suspension mounting points - a weakness of the Elise chassis.		One key differences to the Elise chassis in the Evoras VVA implementation is the removable front sub-frame which carries the front suspension mounts and allows the sub-frame to be replaced in the event of an accident which damages the front suspension mounting points - a weakness of the Elise chassis.

This allows large parts to be made in single piece, thus save bonding and weight.		The Elise's revolutionary chassis is made of extruded aluminium sections joined by glue and rivets.

Comparing their specification and you will know how superior the Elise is:

			Lotus's technology was originated by its supplier, Hydro Aluminium of Denmark. Hydro discovered that aluminium extrusion can be bonded by epoxy resin (glue) if it is adequately prepared by a special chemical in the bonding surface. Surprisingly, glue can bond the sections together strongly and reliably. Most important, the aluminium extruded sections can be made much thinner than traditional welding technique. Why ? because welded joints are weak, so the thickness of material should be increased throughout a member just to make a joint strong enough. Therefore Elise's chassis could be lighter yet stiffer.
