In common with all contemporary Formula One designs, the FW30's basic architecture is built around a carbon fibre, aramid and honeycomb composite material monocoque.
The design carries over the FW29's zero keel, double wishbone suspension arrangement, along with the twin-pillar rear wing.
The FW30's front wing is one area in which the design of the FW29 was not followed.
In place of the older car's two-element wing a three-element design was introduced, similar to that used on the 2007 McLaren MP4-22.
As with the McLaren design the Williams wing's upper element features a central section that is raised up and passes over the tip of the car's, slightly lower, nose cone.
However, unlike the McLaren, the FW30's front wing is suspended from the nose cone using the forward element.

Around the drivers, in accordance with new FIA regulations, the cockpit sides are significantly raised in comparison to previous years.
The exhaust chimneys were altered from the FW29's side-exit design, to a slimmer, vertical-exit one.
Other, less obvious, chassis alterations include an increase in the number of cooling louvres in the upper surfaces of the side pods, made in response to a change in the orientation of the main radiators within the pods, and an increase in the backward sweep of the roll bar-mounted mid wing.
