The new BMW 6 Series Convertible
is available with two engine variants from launch. The
eight-cylinder powerplant in the BMW 650i Convertible produces
300 kW/407 hp, while an exclusive variant of the six-cylinder
in-line engine with BMW TwinPower Turbo, direct injection and
VALVETRONIC –generating 235 kW/320 hp – has been developed for
the BMW 640i Convertible. Both engines team up as standard with
an eight-speed Sports automatic gearbox. Standard-fitted BMW
EfficientDynamics features include the Auto Start-Stop function
in the BMW 640i Convertible.
Chassis technology unmatched in
its segment works in tandem with the cutting-edge engines to
ensure even greater dynamic capability and a similarly
discernible improvement in ride comfort compared to its
predecessor. The new BMW 6 Series Convertible comes as standard
with Drive Dynamic Control, which allows drivers to choose their
own suspension settings, while the Adaptive Drive system is
available as an option with electrically controlled dampers and
roll stabilisation. In addition to the standard-fitted
electromechanical power steering, another unique feature in this
segment is the optional Integral Active Steering system.
The new BMW 6 Series Convertible
also underlines its progressive character with numerous BMW
ConnectedDrive features that none of its rivals can match. The
selection of optional driver assistance systems includes a
rear-view camera, Surround View, BMW Night Vision with
pedestrian recognition and BMW Parking Assistant. The new BMW 6
Series Convertible is the only car in its segment to be
available with a Head-Up Display. Making its debut in the new
soft top, the latest generation of the system uses a broader
palette of colours and three-dimensional graphics to create an
even sharper image.
Majestic power: eight- and
six-cylinder engines with BMW TwinPower Turbo
Instantaneous power development
and majestic torque are the stand-out features of the two
engines available for the new BMW 6 Series Convertible from
launch. The V8 powerplant and six-cylinder in-line unit both
have BMW TwinPower Turbo technology and direct injection, and
combine their sporting character with outstanding smoothness and
exceptional efficiency.
The 4.4-litre eight-cylinder
engine in the new BMW 650i Convertible develops a maximum 300
kW/407 hp between 5,500 and 6,400 rpm, and puts its peak torque
of 600 Newton metres (443 lb-ft) on tap between 1,750 and 4,500
rpm. This unique engine, whose turbochargers are positioned in
the V-shaped area between the cylinder banks, produces an
instantaneous and sustained wave of power, making it a feast for
the enthusiast driver. The new BMW 650i Convertible completes
the sprint from 0 to 100 km/h (62 mph) in 5.0 seconds, and the
engine electronics eventually step in to halt acceleration at
250 km/h (155 mph). This range-topping engine also boasts
extraordinary efficiency for a model in its output class, as
average fuel consumption of 10.7 litres per 100 kilometres in
the EU test cycle (26.4 mpg imp) and CO2 emissions of 249 grams
per kilometre clearly show.
The six-cylinder in-line engine
under the bonnet of the new BMW 640i Convertible complements its
BMW TwinPower Turbo technology and petrol direct injection with
VALVETRONIC fully variable valve control. All of which enables
the 3.0-litre unit to develop a maximum 235 kW/320 hp at 5,800
rpm and maximum torque of 450 Newton metres (332 lb-ft) between
1,300 and 4,500 rpm. This engine propels the BMW 640i
Convertible from 0 to 100 km/h (62 mph) in 5.7 seconds and on to
an electronically limited top speed of 250 km/h (155 mph). Its
average fuel economy in the EU test cycle comes in at 7.9 litres
per 100 kilometres (35.8 mpg imp), while CO2 emissions are 185
grams per kilometre.
Eight-speed Sports automatic and
BMW EfficientDynamics as standard
The eight-speed Sports automatic
gearbox fitted as standard in the new BMW 6 Series Convertible
boasts a combination of sportiness, shift comfort and efficiency
unmatched in its segment. Its minimal converter slip and rapid
and precise gear changes set it apart from the crowd. An
innovative gear set configuration allows this transmission to
offer eight gears and a correspondingly wide gear range – which
optimises the car’s sprinting power yet also allows the driver
to save fuel by driving at low revs – despite its compact
construction and low weight. The driver can also change gear
manually using shift paddles on the steering wheel.
In addition to the efficiency of
the engines and eight-speed Sports automatic, an extensive range
of BMW EfficientDynamics measures also contribute to reducing
fuel consumption and emissions. Technology such as Brake Energy
Regeneration, Electric Power Steering (EPS), the need-based
operation of ancillary components, intelligent lightweight
construction and low-rolling-resistance tyres ensure maximum
efficiency. Plus, the new BMW 640i Convertible is also equipped
with automatic active air flap control and the Auto Start-Stop
function. When the driver draws to a standstill at junctions or
in a traffic jam the engine is automatically switched off. As
soon as the driver releases the brake pedal, the engine starts
up again. If the driver is using the Auto Hold function, the
engine is restarted when the accelerator is depressed.
