The all-metal retractable roof of the 308 CC is a further development of the design first introduced in the 307 CC, and elevates this technology to a new level of sophistication.
The two-part construction consists of a small folding roof panel, and a large, dark-tinted athermic rear screen. When the roof is retracted, the screen separates from the rear quarter panel pillars, allowing extra space in the boot.
The 308 CC’s retractable roof is the most sophisticated iteration of Peugeot’s folding roof design to date, and further evolves the concept already applied to the marque’s previous coupé cabriolet models.
Roof operation is quicker than ever before, allowing the roof to be raised or lowered in only 20 seconds, and while driving below 10 km/h. It also sets new standards as far as accurate fit, water resistance and robustness are concerned, underlining the quality of the design.
Operating the metal roof are five hydraulic actuators, linked to an enclosed electro-hydraulic pump, and a cross-tube located in the boot. The latter links individual systems such as the control rods, the locks and the pantographs with an array of strengthened shafts.
A new electronic control unit oversees the entire roof operation. To ensure an efficient and reliable seal between the roof, the doors and the windows, it lowers all four windows by approximately 50 mm before the roof is operated, and also lowers the windows by 20mm when a door is opened.
This short-drop window system is controlled by a capacitive sensor and a continuously reinitialised magnetic field. When a user’s hand approaches the door handle, the sensor recognises its presence in a matter of milliseconds, and alerts the electronic control unit, which in turn lowers the window to release it from the seal.
Newly developed sensors and logics, featuring improved operating logic, further improve operating reliability. A diagnostic cycle continuously checks sensor operation, while the roof locks are fitted with anti-rattle locking cams.
New U-shaped seals have further improved the roof’s lateral water resistance, while also benefitting noise levels, due to their effective acoustic reduction properties.
The result is a sophisticated roof system that allows a perfectly executed transition from coupé to cabriolet – all at the push of a button.
