BMW takes the
development of intelligent hybrid drive systems to the next level
with the introduction of the BMW ActiveHybrid 5 – another
series-produced model in which a combustion engine and electric
motor join forces to enhance both efficiency and the brand’s
hallmark driving pleasure. The BMW ActiveHybrid 5 brings together a
BMW TwinPower Turbo six-cylinder in-line engine, an electric drive
system and an eight-speed automatic gearbox for the first time. The
latest generation of BMW ActiveHybrid technology also adds precisely
controlled – and therefore extremely effective – energy management
to the mix. All of which gives the BMW ActiveHybrid 5 an exceptional
balance of performance and fuel economy for the premium executive
car class. Its drive system generates combined output of 250 kW/340
hp, allows the car to be driven on electric power alone up to 60
km/h (37 mph), accelerates the BMW ActiveHybrid 5 from 0 to 100 km/h
(62 mph) in 5.9 seconds, limits average fuel consumption to between
6.4 and 7.0 litres per 100 kilometres (44 – 40 mpg imp) and has CO2
emissions of just 149 – 163 grams per kilometre (figures according
to EU test cycle, may vary according to the tyre format specified).
The 225 kW/306 hp six-cylinder in-line engine with BMW TwinPower
Turbo technology in the BMW ActiveHybrid 5 is the same unit renowned
for its free-revving capability, pulling power and efficiency in the
BMW 535i. The electric motor, meanwhile, develops 40 kW/55 hp and is
supplied with energy by a high-performance lithium-ion battery
integrated into the luggage area.
A harmonious blend of power from the two drive systems is
transferred to the rear wheels by the eight-speed automatic gearbox.
In addition to its full-hybrid construction, which enables purely
electric and therefore emission-free driving in urban conditions,
the BMW ActiveHybrid 5 boasts not only the sportiest performance in
its market segment but also a double-digit percentage improvement in
fuel economy over the BMW 535i.
In order to fully exploit the potential of the BMW ActiveHybrid
technology, the intelligent energy management of the power
electronics in the BMW ActiveHybrid 5 uses a host of innovative
functions to ensure the drive system runs efficiently. The
lithium-ion high-performance battery is charged when the car is
coasting or braking, the electric motor performing the role of a
generator feeding energy into the high-voltage battery. By contrast,
under acceleration the electric motor takes on a boost function.
Here, it assists the petrol engine by generating an ultra-dynamic
burst of power, lending the sedan’s sporty driving experience a
noticeably sharper edge. Added to which, while coasting at speeds of
up to 160 km/h (100 mph) in ECO PRO mode, the combustion engine can
be switched off and fully decoupled. This coasting mode combines
comfortable driving with optimum utilisation of the kinetic energy
already generated. To avoid periods with the engine running at idle
– at junctions or in traffic tailbacks, for example – the BMW
ActiveHybrid 5 is equipped with a hybrid start-stop function. Plus,
the power electronics in the BMW ActiveHybrid 5 are linked up with
the standard-fitted navigation system Professional. This allows
forward-looking analysis of the driving situation, enabling the
drive components to be primed to deliver maximum efficiency (the
effect may vary according to the quality of the available navigation
data). All the hybrid-specific components of the drive technology
and energy management systems have been developed specially for use
in the BMW ActiveHybrid 5. The result is an extremely well-rounded
overall concept, which also provides a convincing demonstration of
the BMW ActiveHybrid technology’s qualities out on the road.
Needless to say, all of the new hybrid components are designed to
last for the life of the vehicle.
The BMW ActiveHybrid 5 sees the sporty yet elegant body design of
the BMW 5 Series Sedan complemented by bespoke touches which
highlight the identity of its drive technology. The “ActiveHybrid 5”
lettering on the C-pillars, BMW kidney grille with galvanised slats
and exhaust matt chrome tailpipes set the exterior apart from the
other models in the range. Available as an option, meanwhile, are
18-inch Streamline light-alloy wheels displaying exceptional
aerodynamic efficiency. The BMW ActiveHybrid 5 is the only model in
the BMW 5 Series line-up to be available in the exterior paint shade
Bluewater metallic, and it also stands out visually from all other 5
Series variants with door sill strips bearing “ActiveHybrid 5”
lettering, an aluminium plate on the centre console with the same
ID, a bespoke engine cover and the visible “ActiveHybrid Power Unit”
inscription on the special casing for the high-performance battery
accommodated in the luggage area.
The selection of interior colours, upholstery and interior trim
elements reflect the range offered for the other BMW 5 Series Sedan
variants. And added to the standard-fitted array of
comfort-enhancing features is not only the navigation system
Professional, but also a 4-zone climate control system with
stationary air conditioning. A wide range of driver assistance
systems and BMW ConnectedDrive mobility services, as well as
virtually all the other optional extras available for the
conventionally powered BMW 5 Series Sedan, can also be specified for
the BMW ActiveHybrid 5.
award-winning six-cylinder in-line engine,
newly developed electric drive system.
This is the first time
that a six-cylinder in-line engine has been included as part of a
BMW ActiveHybrid system. The 3.0-litre petrol unit, which develops
225 kW/306 hp and peak torque of 400 Newton metres (295 lb-ft),
represents a passport to increased driving pleasure and efficiency.
The BMW TwinPower Turbo technology of the six-cylinder engine, which
has already won the international Engine of the Year Award two years
in succession, comprises a twin-scroll turbocharger, High Precision
Direct Injection and VALVETRONIC variable valve timing.
The synchronous electric motor of the BMW ActiveHybrid 5 is
integrated into the housing of the eight-speed automatic gearbox,
saving space. The link-up between the electric motor and gearbox is
controlled by a clutch and the motor’s operating temperature is
regulated by the combustion engine’s cooling system. The electric
drive system develops 40 kW/55 hp and makes 210 Newton metres (155
lb-ft) of torque available from rest. The motor is supplied with
energy by a lithium-ion high-performance battery, likewise specially
developed for the BMW ActiveHybrid 5. The high-voltage battery is
encased in a special high-strength housing and positioned between
the wheel arches in the luggage area, providing it with optimum
protection. It consists of 96 cells, has its own cooling system and
offers usable energy capacity of 675 Wh. The integration of the
lithium-ion high-performance battery into the luggage area reduces
the load capacity of the BMW ActiveHybrid 5 to 375 litres, 145
litres lower than that of a BMW 5 Series Sedan variant powered
purely by a combustion engine.
The BMW ActiveHybrid 5 has both a conventional 14-volt power supply
and a high-voltage supply with an operating voltage of 317 volts.
They are linked up by a voltage transformer ensuring that maximum
electric energy can be used to enhance driving dynamics and comfort
in any operating phase. Like the electric motor, the air
conditioning compressor is also fed with power from the lithium-ion
high-performance battery exclusively via the high-voltage supply.
This ensures a pleasant interior climate, even when the combustion
engine is switched off – i.e. when the car is at a standstill,
operating purely on electric power or in coasting mode. In addition,
the stationary climate control function can be used to cool the
interior before the engine is started up.
Intelligently controlled hybrid
technology: unprecedented precision for superior efficiency.
Up to a speed of 60 km/h
(37 mph), the BMW ActiveHybrid 5 can operate in all-electric mode
for zero emissions in town. The lithium-ion high-voltage battery can
store sufficient energy to give an all-electric driving range of up
to four kilometres (approx. 2.5 miles) at an average speed of 35
km/h (22 mph).
The internal combustion engine is only started when the driver
requires more power: it is then engaged automatically. The electric
motor provides a “boost” function to supplement the engine when
accelerating. Maximum combined power is 250 kW/340 hp, with maximum
torque of 450 Newton metres. Under combined ICE/electric power, the
BMW ActiveHybrid 5 delivers a 0 to
100 km/h (62 mph) acceleration time of 5.9 seconds.
Hybrid-specific Auto Start-Stop
function and coasting mode.
Thanks to the specially
designed Hybrid Auto Start-Stop function, there are no compromises
on comfort even when the vehicle is stopped in traffic for longer
periods – after the internal combustion engine is shut off, the
automatic climate control simply runs off the lithium-ion battery.
When the driver releases the brake, the vehicle will restart on
either the electric motor alone or the electric motor and the petrol
engine, depending on the high-voltage battery’s current charge level
and on how much power the driver wants.
Another innovation being pioneered in the BMW ActiveHybrid 5 further
improves efficiency by shutting the internal combustion engine down
not only when the vehicle is stationary, or when driving in town,
but also on overrun. In the BMW ActiveHybrid 5, this coasting mode
is available at any speed up to 160 km/h (100 mph). Coasting mode
switches off the petrol engine and disconnects it from the drive
shaft. From this point on, the BMW ActiveHybrid 5 continues moving
soundlessly, with zero emissions and with no engine braking effect.
The potential efficiency improvements are further enhanced by tyres
with reduced rolling resistance. In coasting mode too, as with
all-electric mode for urban driving, all safety and comfort
functions remain fully operational.
Intelligent energy management with
proactive analysis of the driving situation.
The advanced power
electronics coordinate the operation of the internal combustion
engine and electric motor with precise reference to the driving
situation. For even more efficient energy management in the BMW
ActiveHybrid 5, this functionality has been extended to include
proactive analysis of the driving situation. To support this, the
power electronics are integrated with the standard-fitted
Professional navigation system, which means they can access and
analyse data indicating an upcoming change in external conditions or
driver requirements at a very early stage. Based on this analysis,
the vehicle can be prepared in advance for the relevant requirements
so that all powertrain systems and the on-board electronics are
managed appropriately and in such a way as to make the most
efficient possible use of the available energy.
Factors that may cause a change in powertrain operating strategy
include the topography of the route and speed limits. For example,
if the system knows that a hilly stretch is coming up soon, the BMW
ActiveHybrid 5 can invest all the high-voltage battery’s electrical
energy in providing supplementary driving power, since the battery
will be recharged “at no cost” during the subsequent descent. On
longer downhill sections the electric motor’s generator function,
too, can be enlisted to recharge the high-voltage battery with no
loss of speed. The operating strategy can also be managed so as to
ensure that the high-voltage battery is as fully charged as possible
when nearing the end of the journey, thereby increasing the electric
driving range on the “last lap”.
The operating status of the powertrain components is shown in
intuitive, model-specific displays in the instrument cluster and in
the Control Display of the
BMW ActiveHybrid 5. As well as the energy flow and energy
recuperation display, these include a further gauge next to the rev
counter which shows the boost effect being provided by the electric
motor during acceleration. A display in the iDrive interface
provides a variety of information – for example on the lithium-ion
high-voltage battery’s current charge level and the power-sharing
between the internal combustion engine and the electric motor in the
course of a journey.

specifications of the BMW ActiveHybrid 5 include a double-wishbone
front axle and integral rear axle, electromechanical power steering
including the Servotronic speed-sensitive power assist function, a
high-performance brake system and 17-inch alloy wheels. Dynamic
Damper Control, featuring electronically controlled damping, is

which stabilises the vehicle by applying braking pressure and
reducing engine power, also incorporates functions such as Dynamic
Traction Control (DTC), the Anti-lock Braking System (ABS),
Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake
Assist, Fading Compensation, a Dry Braking function and Start-Off
The hybrid-specific safety features, which protect the lithium-ion
high-voltage battery and the power electronics, are integrated in
the BMW 5 Series’ elaborate integrated active and passive safety
concept. In a collision, high-strength structural components and
large deformation zones help to keep impact forces away from the
passenger cell and also from the hybrid drive components. Other
standard safety systems on the BMW ActiveHybrid 5 include front and
side airbags, side curtain head airbags for both rows of seats,
three-point inertia-reel belts on all seats, belt force limiters and
belt latch tensioners on the front seats and ISOFIX child seat
attachments in the rear.
In the BMW ActiveHybrid 5, too, the standard-fitted Driving
Experience Control switch offers not only Sport+, Sport and Comfort
set-ups (as well as Comfort+ mode if the optional Dynamic Damper
Control is specified), but also ECO PRO mode. The latter supports a
particularly relaxed and fuel-efficient driving style, and makes
more frequent use of all-electric mode. As an alternative to the
standard-fitted automatic transmission, a sports automatic with
faster shift times is optionally available.
BMW ConnectedDrive systems optionally available for the BMW
ActiveHybrid 5 include Park Distance Control, a rear-view camera,
Surround View, Adaptive Headlights, High-Beam Assistant, Speed Limit
Info, BMW Parking Assistant, Lane Change Warning, Lane Departure
Warning, BMW Night Vision with pedestrian recognition and the BMW
Head-Up Display. Innovative technologies also allow in-car
integration of the Apple iPhone, other smartphones and music
players, and use of the Real-Time Traffic Information and Apps
To further enhance
comfort and individuality, the standard-specification 4-zone
automatic climate control and navigation system Professional can be
supplemented by options such as active seats, active seat
ventilation, Comfort Access, the Smart Opener for the tailgate, the
Soft Close Automatic function for the doors, a power-operated glass
roof and high-end audio and rear entertainment systems.
