X6 SAC, for Sports Activity
APN, 19 Dec. 2007.
When the new BMW X6 hits the
European and U.S. markets in the second quarter of
2008, it will bring with it a few "firsts".
Despite its four doors and crossover SUV body, the new
X6 does look also like a coupé, or a coupé version
of its X5
Hence the name SAC, for Sports
Activity Coupé. The Bavarian "Activity" is
practically the equivalent of the American
"Utility", in sports utility vehicle
(SUV). True, modern crossovers are built on unitary
bodies, far away from the traditional body-on-frame
SUVs. But while the latter ones remain the toughest in
off-road applications (utility aspect),
crossovers take their revenge on tarmac (activity).
4877mm (X5: 4854), wheelbase: 2933mm
(same as the X5), width: 1983mm (X5:
1933) and height: 1690mm (X5: 1766).
Dimensions - In size
terms, the available exterior dimensions indicate an
X6 body length of 4877mm (compared to 4854mm for the
X5 and 4569 for the smaller X3), a 2933mm wheelbase
(same as the X5, compared to 2795mm in the X3), 1983mm
width (1933 for the X5 and 1853 for the X3) and 1690mm
height (1766 for the X5 and 1674 for the X3).
as a four-passenger coupé.
Being engineered as a
four-passenger coupé, the new X6 inaugurates a new
automotive niche market, where coupé lines combine
with four-wheel drive identity, without depriving the
passengers from a cargo volume of 570 litres behind
the rear seats (European measurement standards) up to
1450 litres (when folded).
Beyond the Coupé-SUV identity,
other firsts to be brought by the new X6 are the Dynamic
Performance Control system, and a range of four
turbocharged engines. This is the first time in
BMW’s history that an entire model range is
turbocharged, from the top BMW X6 xDrive50i version
with its all-new twin-turbocharged V8 producing 408hp
at 5,500rpm, to the X6 xDrive30d.
on-the-road prices: GB£41,955 for the
X6 xDrive30d, £44,135 for the X6
xDrive35d, and £42,625 for the X6
The X6 will be launched first with
the X6 xDrive30d, xDrive35i and xDrive35d. The X6
xDrive50i goes on sale later in the year (prices will
be announced nearer the launch date). In the USA
market (second quarter), the X6 will be available with
the two petrol (gasoline) engines. In the UK,
the X6 will be launched in May, with on-the-road
prices of GB£41,955 for the X6 xDrive30d, £44,135
for the X6 xDrive35d, and £42,625 for the X6

X6 xDrive50i - The V8
engine will make the X6 xDrive50i the most powerful
production X model BMW has ever produced. With its
408hp (400hp in the U.S. specification) from 4,395cc,
the new 4.4-litre returns a specific output of 92.83hp
per litre. Its 600Nm of torque (450lb.ft in the U.S.
specs, equivalent to 610 Nm) from 1,800rpm through to
4,500rpm propels the X6 from zero to 100 km/h (62mph)
in 5.4 seconds.
Top speed has been
electronically-limited to 250 km/h (155mph). Fuel
consumption on the combined cycle is 22.6 imperial mpg
(UK specs, equivalent to 18.83 US mpg, 12.5 litres /
100 km, 8 km/ litre).
packaging, the new V8 engine is also the first engine
in the world to locate twin-turbochargers and a
catalytic converter within the two banks of the
engine's V. This design allowed engineers to fit the
twin-turbochargers needed for increased performance
without having to reconfigure the double wishbone
xDrive35i - The other petrol engine choice is
the 3.0-litre twin-turbocharged six-cylinder (inline).
Already available in the 1 and 3 Series, it comes now
also in the X6 xDrive35i. Offering 306hp (300hp in the
U.S. specification) from its 2,979cc displacement
(102.72hp per 1,000cc), the BMW X6 xDrive35i produces
peak power at 5,800rpm, with peak torque of 400Nm
(300lb.ft in the U.S. specs, equivalent to 406 Nm)
from 1,300rpm through to 5,000rpm.
The X6 xDrive35i
can sprint from zero to 100 km/h (62mph) in 6.7
seconds before going on to a top speed of 240 km/h
(149mph). Fuel consumption on the combined cycle is
25.9mpg (21.6 US mpg, 10.91 litres / 100 km, 9.17
km/litre) with CO2 emissions of 262g/km.

unit achieves 520Nm of torque from 2,000rpm through to
2,750rpm, providing a zero to 100 km/h (62mph) in 8.0
seconds, with a top speed of 210 km/h (130mph), or 220
km/h (137mph) with the Dynamic Package fitted. The

xDrive35d - Also powered by the 2,993cc
six-cylinder diesel engine with third generation
common-rail technology, but with twin-turbocharging,
the X6 xDrive35d produces 286hp at 4,400rpm (95.55hp

- With BMW’s EfficientDynamics technology, the new
X6 is enhanced by a number of intelligent features,
such as the Brake Energy Regeneration.
Incorporating an Intelligent Alternator Control and an
Absorbent Glass Mat battery to recycle previously lost
energy, it lowers fuel consumption, as the alternator
reduces drag on the engine by only engaging when
required to charge the battery, instead of constantly
draining power from the engine, as is the case with a
traditional alternator. Additionally, the energy
generated by the engine on over-run (under braking or
descending a hill) was also previously wasted. Now
this lost energy is used by the alternator to charge
automatic gearbox with steering
Performance Control - Twinned with the xDrive
four-wheel drive system, Dynamic Performance
Control makes its world debut on the BMW X6. It works
by spreading drive forces from side to side at the two
rear wheels as required in a given situation.
BMW says that
Dynamic Performance Control is the only system of its
kind in the world able to provide its stabilising
effect both under power and with the engine on
over-run. Supplied by ZF (covered
by Motion Trends in June 2007) system works by
detecting possible over- or understeer of the vehicle
in, for example, a bend. When this occurs Dynamic
Performance Control will vary the distribution of
drive forces between the wheels for the best possible
stability, dynamic traction, and forward motion. This
is achieved by transferring additional wheel speed to
the outer rear wheel to push the car round the corner
rather than applying brake force to the inner wheels
as currently happens with traditional stability
In the process,
BMW says that Dynamic Performance Control improves
driving stability at all speeds, not only ensuring
maximum traction when pulling away, and precise
control when entering a bend, but also higher levels
of lateral acceleration and optimum directional
stability when accelerating out of the bend. More
- While it is the third X model to be launched by BMW,
the four-seat X6 is aimed at a different customer to
X3 and X5 owners, appealing to drivers looking for
more sports car characteristics, but still with the
driving feel of a crossover.
From the front,
large air intakes positioned on the outer reaches of
the front bumper highlight the cooling requirements of
the high-performance engine. The contour of the
central air intake, in addition, visually widens the
car for a more sporting appearance.

From the side,
BMW proportions are clear, while the roofline and
relatively long rear body overhang give the car a
stretched coupé / crossover silhouette. Flared wheel
arches, standard 19-inch light-alloy wheels and a wide
rear track (1706mm compared to a 1644mm front track)
underscore the sporting character.

and optional equipment lists vary depending on
markets) with standard 19-inch alloy wheels, Dynamic

include Adaptive Drive handling package, Active
Steering, Head-up Display, Adaptive Headlights,
High-beam Assistant, Reversing Camera and
four-zone climate control. Active
Steering offers the right steering ratio at all
speeds, maintaining direct steering behavior up to a
speed of about 88 km/h (55 mph), as required
particularly for sporty driving. A further advantage
in this case is that the driver only has to turn the
steering wheel twice from lock to lock when parking.
At higher speeds, on the other hand, Active Steering
offers a more indirect transmission ratio in the
interest of steady directional stability and, as a
result, enhanced motoring comfort.
the BMW X6, Active Steering is combined with
Servotronic, thus making an active contribution in
stabilising the car in the event of over-steer in
bends or particularly demanding brake manoeuvres. When
applying the brakes on different surfaces left and
right, for example, that is with a so-called modal
split, Active Steering counter-steers discreetly but
firmly to prevent the car from swerving out of
