A vehicle chassis structure comprises multiple non-ferrous tubular elements 150, 152, 154 joined to form a framework with a reinforcement panel 158 adhesively attached to at least first and second tubular elements 150, 152 which are joined to each other by a welding process. In one embodiment, panel 158 overlaps the welded join 155 between tubular elements 150, 152; alternatively the panel can be rebated so that it does not overlap welded join 155. Panel 158 is preferably a composite panel, such as a glass fibre composite or a carbon fibre composite. Tubular elements 150, 152, 154 are preferably of a lightweight alloy such as an aluminium, titanium or magnesium alloy, which may be reinforced to form a metal matrix composite, and the tubular elements preferably have a non-polygonal cross-section, for example circular or elliptical cross-section. Panel 158 may be a glass fibre composite or a carbon fibre composite.
