In a structure such as that described in WO2009/122178, it is necessary to provide an adhesive bond between composite panels and the tubular framework. We describe a chassis comprising a framework of interconnected tubular-section metallic members and a plurality of composite panels, each panel being adhesively bonded to a plurality of the metallic members, wherein at least one bond between a composite panel and a metallic member is formed by an arcuate formation integral with and extending from an edge of a planar section of the composite panel and fitting around an exterior of the metallic member, and a layer of adhesive along the gap there between extending substantially from the edge of the planar section across a part of but less than the complete angular extent of the arcuate section. We also describe a method of forming a vehicle chassis, comprising the steps of assembling a framework of tubular-section metallic members, providing a plurality of composite members, at least one of which has a planar section and, at an edge thereof, an arcuate formation substantially matching an external profile of a metallic member, applying an adhesive bead along the arcuate formation to a predetermined depth and covering an angular extent of the arcuate formation that is less than the complete extent thereof, bringing together the at least one composite member and the metallic member so that the metallic member sits within the arcuate formation and a spacing between them is less than the predetermined depth.

A vehicle with a load space to provide a chassis comprising a framework (10) comprising a pair of spaced-apart elongate longitudinal members (12, 14) connected by a pair of spaced-apart elongate lateral members (20, 22) and bracing for the thus-defined framework, a rear suspension attached to the rearmost lateral member (20) and comprising a trailing-arm arrangement (52), and a front suspension attached to the front most lateral member (22) and comprising a leading-arm arrangement (58). This creates a rigid core for the chassis, which also provides all four suspension mounting points.

A vehicle suspension comprises an assembly of a hub carrier and a support arm, the support arm being attached to the hub carrier at two points spaced from each other in the direction of travel and extending inwardly therefrom to a support arm attachment point for fixing to a chassis, and a trailing link extending from the assembly in a direction transverse to that of the support arm, toward a trailing link attachment point for fixing to the chassis. The trailing link preferably extends from the assembly in a forward direction, and is preferably connected directly to the hub carrier. A strut can extend upwardly toward an attachment point for fixing to a chassis, to provide a spring and damper. The support arm can comprise a pair of arms extending divergently from the attachment point to each of the two points. A toe control link extends generally parallel to but spaced from the rear arm, linking the hub carrier to the chassis to provide geometry control under high load conditions. The invention further relates to a vehicle, comprising a chassis and at least two wheels, one on each side of the vehicle, each wheel being attached to the chassis via such a suspension.

The provision of impact structures is difficult in the case of small vehicles, due to the shortage of working depth. We propose to use the wheel and tyre as part of the deformable structures, which reduces the overall weight of the vehicle and requires little or no additional space in which to provide the impact structures. There is still a need to control the movement of the wheel under impact, but we have found that this can be done by appropriate design of the suspension components so that they react in a defined manner to an impact and guide the wheel in the correct manner. The present invention therefore provides a vehicle comprising a chassis, at least one wheel, and a hub carrier on which the wheel is mounted, together with a suspension connecting the hub carrier to the chassis that includes a plurality of first links extending towards the chassis in at least one of an inward or an upward direction and at least one second link extending towards the chassis in a longitudinal direction, and a crushable structure attached to the chassis at a location aligned with a path of the wheel under impact after collapse of the longitudinally extending link.

ELG Carbon Fibre Ltd and Gordon Murray Design Ltd have combined to create novel carbon fibre materials made from recycled carbon fibre waste that would have otherwise gone to landfill. These new materials are suitable for a whole range of applications which may include Aerospace, Military and Transportation as well as emerging markets that demonstrate a need for low cost carbon fibre reinforcements. Utilizing recycled carbon fibre in Gordon Murray Design’s patented iStream® process, for example, has created the opportunity for recycled carbon fibres to be introduced into mass production, low cost vehicle chassis structures.

Gordon Murray Designs innovative and ground breaking iStream automotive manufacturing technology allows significant reductions in setup, production costs, vehicle mass, and lifecycle CO2 emissions, whilst offering cost effective design flexibility that exceeds current Euro NCAP occupant and pedestrian impact regulations. The project consortium of Gordon Murray Design, Innoval Technology Limited, Constellium and Brunel University (BCAST) aim to develop an iStream monocoque that is 30 - 40% lighter than the incumbent steel/glass fibre composite structure. Using a novel high strength extrusion alloy combined with advanced composite panels based on recycled carbon fibre, the project aims to further reduce CO2 emissions through significant lightweighting, whilst maintaining the high volume, low cost benefits of the original disruptive iStream technology. The project also aims to take another major step, making full use of the iStream process, towards a new generation of lightweight vehicles for the UK market that can have a major impact on the UK government’s carbon reduction targets for the UK vehicle fleet
