Pininfarina Sverige AB — a joint venture between Pininfarina and Volvo (and the first time Pininfarina has manufactured outside Italy). The C70 retractable hardtop replaces its predecessors two models: both the convertible and the coupé, the latter which had been absent from Volvo's lineup since 2003. The retractable hardtop went on sale in the U.S. in spring 2006. The Insurance Institute for Highway Safety in the United States conducted its first crash tests of several convertibles, designating the C70 a "Top Safety Pick". Top mechanism The three-section hardtop assembly, manufactured by Pininfarina in Uddevalla by its subsidiary RHTU Sverige A.B. and developed with Webasto, raises or lowers in under 30 seconds and includes a global window switch that allows simultaneous raising or lowering of all windows, and a button to power-activate the raising of the folded top stack within the trunk — specifically to increase access to cargo storage when the top is lowered. Operation of the retractable hard top is possible only when the car is stationary and requires no extra space behind the car while the roof is being raised or lowered but requires a height clearance of six feet seven inches (2,006.6 mm) — and requires the driver to hold the console button for the full operation. The top features a fabric headliner that unfurls and is tensioned by wires as the roof moves into place, as well as mesh wind blocker that clips over the rear seats when driving with two front passengers. The blocker has zippered openings for parcel storage and folds in half for trunk stowage. The trunk lid, which opens both in a rear-hinged mode to stow the folding roof as well as standard a front-hinged mode for luggage loading, is aluminum — while the three roof sections are steel. A trunk divider enables assessment of precisely how much can be loaded with the roof down. Trunk space is 13 cubic feet with the top raised (368.12 L) and seven cubic feet (198.22 L) with the top lowered. A hatch in the backrest of the rear seat enables transport of long objects inside the car, e.g., skis. Overall body rigidity is improved by approximately 15 percent when the roof is raised. Safety Safety systems include a door-mounted side impact protection inflatable which inflates upward when activated. The curtain has an extra stiff construction with double rows of slats that are slightly offset from
