Good Reasons for More Driving Pleasure.

• Supreme all-round economy featured as standard the world
over.
• BMW 530d with BMW BluePerformance fulfilling the EU6 emission
standard.
• BMW 520d with Auto Start Stop fitted as standard offering the
lowest fuel consumption and CO2 levels in its segment.

The new BMW 5 Series is the epitome of driving pleasure in the
upper midrange market. With its superior suspension technology and
outstanding comfort including numerous features carried down
directly from the luxury performance class, the new BMW 5 Series is
the ideal choice for the truly discerning motorist who uses his car
frequently and with passion as a sophisticated means of
transport.

The many qualities of the new sedan reflect the broad range of
competence offered by the world’s leading manufacturer of premium
cars, in this case in particularly concentrated form. The essential
features thus also include an unparalleled balance of fuel economy
and driving pleasure resulting from the BMW EfficientDynamics
development strategy featured in the new BMW 5 Series Sedan
worldwide as standard and in a particularly wide range of equipment
and technologies.

Outstanding economy and exemplary emission management are
therefore further good reasons to enjoy supreme driving pleasure in
the BMW 5 Series. All drive units available for the new BMW 5
Series Sedan were created as part of the BMW EfficientDynamics
development strategy. Apart from the petrol and diesel engines
optimised for minimum consumption, various transmissions offering a
particularly high standard of efficiency, lightweight construction
on a broad scale, refined aerodynamics in every detail, and
numerous other efficiency features ensure that every version of the
new BMW 5 Series offers exceptionally low fuel consumption and
emissions in its respective performance class.

In this process the new BMW 520d is increasing its leading
position as the most fuel-efficient car in its segment. In
combination with automatic transmission, the BMW 530d is even
available as an option with BluePerformance technology, making this
the fourth model within the BMW range to already fulfil the EU6
emission standard today not coming into force until the year
2014.

The petrol engines in the new BMW 5 Series: a
perfect combination of innovations for supreme
efficiency.

Offering the spontaneity, fast-revving performance and
refinement so typical of the brand, combined with unparalleled
efficiency, the petrol engines featured in the new BMW 5 Series
Sedan come with a standard quite unparalleled in the market. Both
the eight-cylinder power unit in the top-of-the-range BMW 550i and
the three straight-six engines come with outstanding technical
innovations created in the context of BMW EfficientDynamics. And
the specific combination of technologies gives each of the four
drive units its own quite unique characteristics.

The most important feature shared by all petrol engines is fuel
supply by means of second-generation direct fuel injection. Already
well-known as High Precision Injection, this advanced system uses
injectors positioned in the middle between the valves and in the
immediate vicinity of the spark plug for the precise dosage of
fuel, measurably reducing fuel consumption also in everyday
traffic.

A particularly efficient version of High Precision Injection is
to be admired in the six-cylinder engines driving the new BMW 528i
and the new BMW 523i. Direct injection in the lean-burn mode gives
these models particularly good fuel economy. Referred to as
stratified charging, this process forms various interacting layers
of different fuel/air mixtures within the combustion chamber, the
share of petrol in the mixture decreasing continuously with an
increasing distance from the spark plug. A particularly rich and
therefore ignitable fuel/air mixture is therefore available only in
the direct vicinity of the spark plug.

As soon as this mixture is ignited, the leaner layers at a
greater distance from the spark plug will also burn in a clean and
consistent process. In the V8 power unit of the new BMW 550i and in
the straight-six engine featured in the new BMW 535i High Precision
Injection is combined with turbocharging. BMW TwinPower Turbo
Technology provides power and performance characteristics a
naturally-aspirated engine would only be able to offer on much
larger capacity, making it heavier and obviously consuming more
fuel and generating more emissions.

The eight-cylinder with BMW TwinPower Turbo and High Precision
Injection is the only petrol engine of its kind with a turbocharger
and catalysts arranged within the V-section between the two rows of
cylinders, and at the same time it is the world’s most efficient
power unit in its performance class. Compared with its predecessor,
the new BMW 550i offers 30 kW more power on approximately 5 per
cent less fuel.

For the first time the six-cylinder in the BMW 535i combines BMW
TwinPower Turbo Technology and High Precision Injection with fully
variable VALVETRONIC valve control. The result is infinite
adjustment of valve stroke and valve timing on the intake side,
reducing throttle losses in the charge cycle to a minimum and
making particularly efficient use of the energy in the fuel. A
further advantage is the response of the engine optimised to an
even higher standard.

Developing 225 kW/306 hp, the power unit featured in the new BMW
535i accelerates this outstanding sedan to 100 km/h in 6.0 seconds,
combined with average fuel consumption in the EU test cycle quite
unique in this class of just 8.5 litres/100 kilometres, equal to
33.2 mpg imp. The permanent, ongoing development of drive units in
the context of BMW EfficientDynamics also means the optimisation of
weight.

Hence, the drive units in both the new BMW 550i and the new BMW
535i are made largely of aluminium, while the straight-six engines
in the BMW 528i and the BMW 523i come with a composite
magnesium/aluminium crankcase again some 24 per cent lighter than a
comparable aluminium block. Such optimisation of weight benefits
not only the efficiency, but also the agility of the respective
vehicle. All versions of the new BMW 5 Series Sedan come with
almost perfect 50:50 weight distribution front-to-rear.

In combination with rear-wheel drive, such harmonious axle load
distribution is indeed crucial to the dynamic and, at the same
time, superior driving behaviour of the new BMW 5 Series Sedan.

Full of torque, light, efficient: the latest
generation of diesel engines.

The diesel versions of the new BMW 5 Series Sedan also offer
state-of-theart drivetrain technology. All-aluminium construction,
common-rail direct fuel injection of the latest generation and
turbocharging give both the fourand six-cylinder diesels truly
impressive torque and pulling force, supreme smoothness and
unparalleled efficiency.

The BMW 530d and the BMW 525d come with two representatives of a
new generation of straight-six diesels – outstanding power units
featuring a wide range of innovations for unusually efficient and
clean combustion. Further weight reduction compared with the former
engine in each case also serves to improve the efficiency and
agility of both models. Both engines displace 3.0 litres and come
with an optimised turbocharger system with variable intake geometry
providing superior power and torque from an early point. Fuel
supply through common-rail direct injection of the latest
generation is provided by piezo-injectors operating at a pressure
of up to 1,800 bar on the BMW 530d and 1,600 bar on the BMW
525d.

Compared with their respective predecessors, the new BMW 530d
and the new BMW 525d offer an increase in engine output by 7 and,
respectively, 5 kW, with average fuel consumption in the EU test
cycle down by up to 4 per cent. As an option the new BMW 530d with
automatic transmission may be further upgraded by BMW
BluePerformance Technology. Offering this unique system, BMW is
once again increasing its lead in the introduction of exhaust gas
management, substantially reducing nitric oxide emissions (NOX) to
an even lower level.

On the new BMW 530d with BMW BluePerformance, the diesel
particulates filter and the oxidation catalyst likewise featured as
standard are supplemented by an NOX storage catalyst operating
without the slightest maintenance throughout the entire lifecycle
of the car and not requiring any additional operating media. As a
result, exhaust management of this standard already reduces nitric
oxides to the level not required by law until the introduction of
EU6 in 2014.

Consistent enhancement of its four-cylinder diesel also gives
the new BMW 520d yet a further improved balance of performance and
fuel economy. Maximum output of this 2.0-litre aluminium engine is
up by 5 to 135 kW/184 hp, peak torque is up by 30 to 380
Newton-metres/280 lb-ft. At the same time the new BMW 520d offers
average fuel consumption of 5.0 litres/100 kilometres (equal to
56.5 mpg imp) in the EU test cycle and a CO2 rating of 132 grams
per kilometre (provisional figures), thus enhancing its leadership
as the most fuel-efficient and lowest-emission car in its
segment.

Making its debut in the BMW 5 Series: Auto Start
Stop function.

The new BMW 520d comes as standard with an Auto Start Stop
function reducing the engine idle period when coming to a short
stop at road junctions or in traffic congestion: As soon as the
driver moves the gearshift lever to neutral and takes his foot off
the clutch pedal, the engine is switched off automatically. Then,
once the driver is able to go on, all he has to do is press the
clutch to start the engine without the slightest delay.

All manual gearbox versions of the new BMW 5 Series Sedan
furthermore come as standard with a gearshift point indicator. An
arrow symbol flashing on in the instrument cluster and specifying
the optimum gear shows the driver the ideal point to shift gears.
Then, depending on driving conditions, the electronic engine
control unit calculates the optimum point for shifting gears in the
interest of maximum fuel economy.

Brake Energy Regeneration including a recuperation
display.

Likewise featured as standard, Brake Energy Regeneration,
ensuring intelligent management of energy flow in the car,
concentrates the generation of electric power for the on-board
network on overrun and the application of the brakes. This takes
the usual load off the engine and ensures highly efficient
generation of electric energy largely without any additional
consumption of fuel. As long as the engine is pulling the car, on
the other hand, the generator is generally disconnected in order to
provide more power for that Sheer Driving Pleasure so typical of
BMW.

In the new BMW 5 Series Sedan the instrument cluster is
supplemented by a recuperation display. This graphic display next
to the current consumption indicator at the bottom of the rev
counter presents the generation of electric power in overrun and
while applying the brakes, the blue arrow being activated as long
as Brake Energy Regeneration feeds energy generated without
the
consumption of fuel into the on-board network.

Electric Power Steering and on-demand management of
ancillary units for reduced consumption of
energy.

On-demand management of ancillary units and Electric Power
Steering serve to further refine energy management in the car. The
coolant pump masterminded as a function of current demand, for
example, consumes far less energy than a conventional system
permanently running under full capacity. The pressure-controlled
fuel pump, the use of on-demand pump technology on the suspension
control system and the map-controlled oil pump on the BMW 528i, BMW
523i and BMW 535i, in turn, also help to maximise the use and
consumption of energy.

Introduction of a new steering system for the BMW 5 Series
likewise helps to boost efficiency. The servo motor on EPS Electric
Power Steering is activated only when power assistance is really
required or is desired by the driver. These technologies reduce the
demand for electric energy, with the amount of primary energy
converted into electricity by the generator dropping substantially
in the process. And with the loss of power on a conventional a/c
compressor also being reduced significantly by intelligent control,
the compressor on the new BMW 5 Series Sedan is separated by a
magnetic clutch from the drive belt as soon as the air conditioning
is deactivated.

Reduction of friction losses is an overriding objective pursued
consistently on all engine units and ancillaries. Use of a special
light transmission fluid in conjunction with a reduced amount of
fluid in the final drive cuts back both friction and oil splash
losses immediately after setting out. Like the new BMW 7 Series,
the new BMW 5 Series Sedan also comes with its final drive in
aluminium, warming up more quickly and reducing thermal loads at
high speeds.

The reduction of air resistance also serves to cut back fuel
consumption. As a result, all versions of the new BMW 5 Series
Sedan with the exception of the BMW 550i come with active cooling
air flaps opening or closing specifically according to current
driving conditions. This further improves the aerodynamic qualities
of the car whenever the demand for cooling air remains at a low
level, just as the extra-smooth underfloor promotes the flow of air
beneath the vehicle.

Efficient power transmission: manual gearbox with
dry sump lubrication and eight-speed automatic
transmission.

The new BMW 5 Series Sedan features a new generation of
six-speed manual gearboxes and, as an option (standard in the BMW
550i), an eight-speed automatic transmission. All transmissions
stand out through an even higher degree of efficiency, compact
dimensions and low weight. The new manual gearbox on the BMW 535i,
the BMW 525d and the BMW 520d comes with dry sump
lubrication and a modified gearset concept for even greater
gearshift comfort and even lower drag losses within the
gearset.

Fully controlled oil supply serves furthermore to avoid oil
splash losses otherwise suffered in the process of distributing
large amounts of oil. The eight-speed automatic transmission also
complies in full with the principles of BMW EfficientDynamics,
likewise featuring innovative gearset configuration with additional
gears and a larger spread of increments versus the former six-speed
automatic transmission without any negative effects in terms of
size, weight, and the inner efficiency of the system.

Shifting gears very quickly and providing direct access to the
target gear lane when shifting back for maximum acceleration, the
eight-speed automatic transmission gives the new sedan even greater
driving dynamics and performance. At the same time converter slip
restricted to the setting-off process and reduced to a minimum even
under such conditions, the high degree of inner efficiency, low
frictional losses with only two clutches open at a time, longer
transmission ratios in higher gears and transmission management for
driving smoothly at low engine speeds, all act together to
considerably reduce fuel consumption versus the former six-speed
automatic transmission.

Even this is not all: In combination with the eight-speed
automatic transmission, the six-cylinder models offer the same or
even lower consumption figures and CO2 ratings than their
counterparts with manual gearbox. As an example, average fuel
consumption of the new BMW 530d with manual gearbox in the EU test
cycle is 6.3 litres/100 km or 44.8 mpg imp, average fuel
consumption of the same model with eight-speed automatic
transmission is 6.2 litres/100km or 45.6 mpg imp.

Intelligent lightweight construction of even greater
fuel economy.

Appropriate choice of the right materials helps to optimise
weight also on the new BMW 5 Series Sedan, enhancing both the
agility of the car as well as its fuel economy and emission
rating.
This optimisation of weight comes together with a further increase
in passive safety and is ensured in particular through the
appropriate use of high-strength multi-phase steel,
ultra-high-strength hot-moulded steel, and aluminium.

The large share of high-strength and ultra-high-strength steel
gives the safety passenger cell of the new BMW 5 Series Sedan
maximum stiffness and stability without the additional use of
material. With optimised weight, the positive properties of the
steel used allow an increase in mean body strength and stiffness by
55 per cent over the former model. The standard of lightweight
construction quality defining the torsional stiffness of the
vehicle as a function of its footprint and weight has also been
significantly improved. Spring supports made of pressure-cast
aluminium enhance the driving dynamics of the new BMW 5 Series in
two respects, making the entire front section even stiffer and,
through their low weight, further improving the overall balance of
the car.

For the first time the doors of the BMW 5 Series Sedan are made
of aluminium, reducing weight by approximately 23 kg or 50 lb
versus a conventional structure. The front side panels, the engine
compartment lid and a large number of the front and rear axle
components are also made of this particularly light metal.
