-speed sports automatic
transmission with double
clutch.
This innovative transmission
(optionally available for the
BMW i Convertible) has two
separate clutches for the odd
and even gears. When one gear
is disengaged, the next one is
already engaged – minimising
shift times, and maximising
precision. So you can accelerate
without any interruption of power,
just like in a sports car.
Active Steering.
Every bend is different. That is
why the Active Steering system,
available as an option for the
six-cylinder models, adjusts both
steering ratio and steering force
as a function of road speed. At low
speeds – for example when parking –
two turns of the steering wheel are
enough to go from lock to lock. At
higher speeds, the steering wheel
must be turned further to achieve
the same effect, enhancing stability.
Dynamic Stability Control
(DSC).
Highly sensitive sensors track
vehicle status on a permanent,
practically real-time basis and
optimise directional stability and
traction as required, via engine and
brake management interventions.
This makes it easier to control the
vehicle in poor conditions, enhancing
both safety and driving pleasure.
The BMW Series Convertible features a whole host of innovative technologies to
help you get the most out of each drive. Together, they ensure that you enjoy
maximum driving pleasure, in maximum safety.
THE FEELING OF DRIVING THE BMW SERIES
CONVERTIBLE IS BEYOND DESCRIPTION.

Lightweight chassis.
The almost perfect : front-rear
weight distribution ensures that the
BMW Series Convertible stays
safely on track, with neutral
steering, high directional stability
and superb traction. Together, all
these systems ensure a level of
dynamic performance that offers
a very intense driving experience.
In addition, the aluminium double-
joint trailing-arm front axle increases
dynamic ability, while ensuring
superb ride comfort.
Rollover protection system.
The rollover protection system
tucked away behind the rear seat
backs ensures the necessary
headroom in the event of a crash.
Highly accurate sensors react to
any violation of defi ned limits for
parameters such as vehicle angle,
longitudinal and lateral acceleration
or loss of ground contact. In such
a situation, the rollover bars are
deployed from behind the rear
headrests within fractions of a second.
Airbags.
In a BMW, all safety features
complement each other perfectly.
Four airbags offer specifi c protection:
the driver and front passenger
airbags and head/thorax airbags
for the front seats. They greatly
decrease the risk of injuries to the
head, pelvic and chest areas.
Occupant cell.
The body uses high-strength
materials and an optimised
structural design to ensure a
maximum of passive safety in the
event of a front, side or tail-end
collision. Thanks to defi ned
deformation zones, the body
structure can absorb impact forces,
helping to protect the occupants.
