Without parallel worldwide, the
new engine gives the BMW M550d xDrive Sedan, BMW M550d xDrive
Touring, BMW X5 M50d and BMW X6 M50d performance figures head
and shoulders above those of the diesel models currently topping
their respective model series. The new M Performance TwinPower
Turbo technology lays on a significant increase in output and
torque across an extremely wide rev range. And yet despite this
enhanced power delivery, fuel consumption and emissions figures
in the EU test cycle are almost unchanged.
Premiere: six-cylinder
in-line diesel engine with three turbochargers.
The market launch of the first BMW M Performance Automobiles
also sees the premiere of the most powerful diesel engine ever
fitted in one of the brand's models. The new unit shows BMW
demonstrating its commitment to the development of ultra-sporty
yet impressively efficient diesel powerplants. Globally unique
technological highlights open the door to a new dimension in
power development. The six-cylinder in-line engine developed for
the BMW M Performance Automobiles uses its 2,993 cc displacement
to generate maximum output of 280 kW/381 hp, giving the new
diesel unit a specific output of 93.6 kW/127.3 hp per litre of
displacement. No less imposing is the engine's maximum torque of
740 Newton metres (546 lb-ft), all of which the driver will find
on tap as low down as 2,000 rpm.
Playing a central role in this
increase in power is M Performance TwinPower Turbo technology.
For the first time, a BMW engine will feature three
turbochargers. The size, arrangement and interplay strategy of
the turbos are designed to guarantee maximum power delivery
across a wide rev band. The system comprises two relatively
small turbochargers and one large turbo, which join forces
precisely to deliver the amount of power required. According to
the driving situation, the low moment of inertia of the small
turbochargers is exploited to the full to deliver razor-sharp
responses, while the link-up with the large turbo is maximised
to generate as much charge pressure as possible.
This innovative and globally
unique multi-stage turbocharging concept represents a
particularly efficient method of boosting output. In addition,
the efficiency of the new diesel engine is further optimised by
innovations including a new development stage in common-rail
direct injection technology, featuring piezo injectors working
with maximum pressure of 2,200 bar. The impressive quantity and
quality of the technical innovations on hand complement the
unrivalled development expertise of BMW in the development of
diesel engines. The new powerplant strikes the most effective
balance between output and fuel consumption of any
series-produced unit of its kind.
The BMW M550d xDrive: a
new benchmark in sporty driving pleasure and efficiency in the
BMW 5 Series segment.
The unique properties of the new six-cylinder diesel engine play
a key role in enabling the BMW M Performance Automobiles to
redefine the relationship between driving pleasure and economy -
and therefore ensure the BMW M550d xDrive and BMW M550d xDrive
Touring act as extremely effective advertisements for BMW
EfficientDynamics technology in the BMW 5 Series segment. These
models embody a particularly high-level application of the
principle of increased performance coupled with ultra-low fuel
consumption and CO2 emissions. The typically M
interpretation of the BMW 5 Series' characteristics also allows
drivers to experience the harmony of sporting capability and
ride comfort, fascination and everyday usability in
extraordinary depth.
Both the Sedan and Touring
models prove more impressively than ever that the hallmark
pulling power of a diesel engine can be converted into
inspirational driving dynamics. The BMW M550d xDrive Sedan
accelerates from 0 to 100 km/h (62 mph) in 4.7 seconds, while
the BMW M550d xDrive Touring covers the same sprint in 4.9
seconds. The two models showcase the efficiency benefits of
diesel technology equally convincingly. In the EU test cycle the
Sedan records fuel consumption of just 6.3 litres per 100
kilometres (44.8 mpg imp), the Touring 6.4 l/100 km (44.1 mpg
imp). CO2 emissions are 165 grams per kilometre for
the BMW M550d xDrive Sedan and 169 g/km for the BMW M550d xDrive
Touring. Both models also meet the requirements specified by the
EU6 exhaust standard.
Model-specific modifications
governing power transfer, chassis and design enable a textbook M
conversion of engine output into sporty driving pleasure. The
standard-fitted eight-speed Sports automatic transmission comes
with gearshift paddles on the steering wheel and is given
model-specific settings, enabling even more rapid gear changes
and helping the engine's performance characteristics to be
exploited to the greatest possible degree. Meanwhile, BMW xDrive
improves the cars' cornering dynamics, as well as enhancing
traction and directional stability. The electronic
all-wheel-drive system follows a control strategy tailored to
each model. This allows the threat of understeer in extremely
dynamic driving situations to be counteracted by adjustments to
the power split, without the DSC (Dynamic Stability Control)
system linked up to xDrive having to intervene. Meanwhile, the
air channelling properties, handling and appearance of both BMW
M550d xDrive variants benefit from aerodynamically optimised
body elements at the front and rear, Ferric Grey exterior
mirrors and air intake bars, and exclusive 20-inch light-alloy
wheels (available as an option).
The BMW X5 M50d and BMW
X6 M50d: an imposing presence in both the acceleration and
efficiency rankings.
Outstanding powertrain and chassis technology in combination
with xDrive intelligent all-wheel drive allow the BMW X5 Sports
Activity Vehicle and BMW X6 Sports Activity Coupe to display
extraordinary poise and assurance. The BMW M Performance
Automobiles based on the two BMW X models take these character
traits to a whole new level. Thanks to the most powerful diesel
engine in the BMW engine range, allied to the optimised power
transfer, handling properties and aerodynamic balance for which
M cars are renowned, the BMW X5 M50d and BMW X6 M50d set new
standards in their respective classes in terms of sportiness,
conceptual harmony and efficiency.
With its maximum output of 280
kW/381 hp and peak torque of 740 Newton metres (546 lb-ft) the
engine developed for the BMW M Performance Automobiles also
brings a level of performance to the two BMW X models which no
other diesel-powered car in their segments can match. The BMW X5
M50d accelerates from 0 to 100 km/h (62 mph) in 5.4 seconds, the
BMW X6 M50d in just 5.3 seconds, while average fuel consumption
in the EU test cycle stands at 7.5 litres per 100 kilometres
(37.7 mpg imp) for the Sports Activity Vehicle and 7.7 l/100 km
(36.7 mpg imp) for the Sports Activity Coupé - only slightly
above the figures for the existing diesel variants of the two
models. CO2 emissions are 199 grams per kilometre for
the BMW X5 M50d and 204 g/km for the BMW X6 M50d.
The eight-speed Sports
automatic transmission with enhanced gearshift dynamics and the
xDrive all-wheel-drive system - tuned to suit the individual
model and emphasise the traditional rear-wheel set-up of BMW
cars - transfer drive to the road with characteristic élan.
Chassis technology which has likewise been modified using BMW M
GmbH expertise ensures that the hallmark agility of BMW X models
is geared even more intently to enhancing sporting capability.
The BMW X5 M50d and BMW X6 M50d also underline their dynamic
tendencies in the form of model-specific body features, which
optimise both the supply of cooling air for the engine and the
cars' aerodynamic properties. 19-inch (BMW X6 M50d: 20-inch) M
light-alloy wheels are also fitted as standard on these models.
20-inch light-alloy wheels in Ferric Grey developed exclusively
for the BMW M Performance Automobiles can be specified as an
option. Plus, Ferric Grey metallic exterior mirror caps and air
intake bars - another distinguishing feature of BMW M
Performance Automobiles - give the cars an even more individual
visual appearance.
