feature, the BMW 5 Series Gran Turismo being BMW’s first four-door model to
boast doors with frameless side windows – and this is also the first large-scale
production model from BMW to feature doors in aluminium shell construction.
The use of aluminium doors alone, replacing conventional steel doors, reduces
the overall weight of the BMW 5 Series Gran Turismo by no less than 28 kg or
62
lb. A further advantage is that the frameless side windows let in even more
light to brighten up the interior.
Despite this particular feature, the BMW 5 Series Gran Turismo, as yet another
innovation in automotive engineering and car production, is available with an
electrically operated sunblind on each of the side windows at the rear.
On account of its particular deformation characteristics, aluminium demands
a much more intricate production process than steel. But the development and
use of a new structural concept serves nevertheless to retain the proven shell
structure of the doors, offering the demanding design features so typical of
BMW also in the use of aluminium.
Unique: two-piece tailgate with highly practical, independently
operating opening and closing functions.
The two-piece tailgate featured for the first time on a BMW combines excep-
tional comfort with utmost variability in loading the car. The tailgate is made up
of a small opening beneath the rear window and a large opening like on BMW’s
X-models, both opening independently of one another.
As an option, the large tailgate section may also be closed automatically at the
touch of a button.
A central pressure-cast aluminium frame ensures supreme strength and
stiffness and is indeed the largest pressure-cast component ever to be used in
a car with this kind of precision and accurate operation. These features alone
make the two-piece tailgate of the BMW 5 Series Gran Turismo quite unique
versus all the car’s competitors.
Both the small and the large tailgate opening come with bracket hinges turning
to the outside, and the large opening also comes with its own Soft Close
Automatic closing mechanism.
