A motorcar with an openable hard top

A motorcar with an openable hard top is of the type in which the roof (2) comprises a front portion (3) connected releasably to the upper cross-member of the windscreen (5) and a transparent rear portion (4) which is articulated about a horizontal transverse axis (6) to two side pillars (7) of the body. The roof (2) can be opened in known manner by being pivoted rearwardly about the said transverse axis (6) until it bears on the rear boot lid (10) which has two front arms (11) that extend upwards and are articulated to the body about the same horizontal transverse axis (6) about which the roof (2) is articulated. When the roof is in the closed position, the end edge (4a) of the transparent rear portion (4) of the roof (2) is situated at the same height as the bases of the two side pillars (7) of the body to which the roof (2) is articulated. The transparent rear portion (4) of the roof acts as a rear window when the roof is in the closed position, and has a curved profile such as to act as an anti-turbulence element with respect to the passengers when the roof is in the open position.
