These early release 2008 5
Series models represent the most significant update since their introduction in
2003. Adopting the new engines introduced in the 3 Series Coupe, the 6-cylinder
Sedans and Sport Wagon receive new model designations, reflecting a marked
boost in power. Last year’s 525i and 525xi both get the new, 230-horsepower
iteration of BMW’s remarkable aluminum/magnesium composite N52 engine, along
with new 528i and 528xi nomenclature. Similarly, the 530i and 530xi become the
535i and 535xi, the new designations signifying the addition of BMW’s latest,
300-horsepower N54 twin-turbo inline-6. Included in this upgrade is the 2008
535xi Sports Wagon, its 300-horsepower eclipsing the old 290-hp V-8 540i and
making it the most powerful Sports Wagon BMW has ever offered in the
In addition to the
horsepower boost, new performance features include a quicker-shifting Sport Automatic
transmission for the rear-drive 535i and 550i Sedans, which also provides
fingertip shift control via steering-wheel-mounted paddles. This is in addition
to the new, updated STEPTRONIC
that is now a no-cost option on all 5 Series models. New Sport Package contents
bring 18-inch wheels and run-flat performance tires to all 6-cylinder models,
including staggered-width 18-inch tires on the rear-drive 535i
New technological features
also make their appearance for ’08. First among these is BMW’s Lane Departure
Warning system, a camera-based system that monitors lane placement, and discreetly
notifies the driver via mild steering wheel vibration of any motions that might
indicate an inadvertent lane change. The convenience of Active Cruise Control
is extended via a new Stop and Go feature, which enables the system to function
even in heavy traffic. Active Cruise allows the vehicle to come to a complete
stop without losing its setting, then accelerate back up to set speed with only
a touch of the accelerator pedal from the driver. Audio options expand with a
USB Adapter for an iPod or MP3 player. And BMW’s leading-edge iDrive system
adds a row of programmable “favorites” buttons, which can be used for anything
from radio-station presets to pre-programmed destinations with the optional
navigation system.
As in the past, all BMW automobiles
and SAVs include BMW Ultimate Service, which
includes 4 year, unlimited mileage Roadside Assistance, 4 year / 50,000 mile
New Vehicle Limited Warranty and BMW Maintenance Program at no extra cost. In
addition, all 5 Series BMWs also include a 4 year membership in BMW Assist
Safety Services as standard equipment.
With all these changes for
2008, BMW’s 5 Series again reasserts itself as the class leader in the midsize
performance-luxury field.

Power &
performance features:
A more-powerful base engine,
twin-turbo performance, and a superlative V-8 all complement the most
sophisticated chassis in the class.
BMW’s engines have become legendary for their
performance, smoothness, and sophistication—attributes that apply equally well to
BMW’s inline-6s and V-8s. The 5 Series offers three of these engines—two
6-cylinders and one V-8—including the company’s first turbocharged engine in
more than three decades. From the base 528i to the range-topping 550i, the 5
Series offers the most impressive range of powerplants in the class, all backed
by 6-speed transmissions, manual or automatic.
As the first full-production aluminum/magnesium
composite engine every offered, the 3.0-liter N52 inline-6 carries on BMW’s
tradition of building cutting-edge engines that combine outstanding power,
unparalleled refinement and excellent fuel economy. For 2008, this engine
receives a boost to 230 horsepower, making the 528i/xi Sedans the most powerful
entry-level 5 Series ever offered. Similarly, the new 300-hp twin-turbo 535i/xi
Sedans and Sports Wagon are the quickest 6-cylinder-powered 5 Series cars yet. And
the range-topping 550i offers the same 360-horsepower V-8 as BMW’s 750Li
These exemplary engines reside in a chassis that
includes aluminum suspension, large-diameter disc brakes, performance tires on
17-, 18- or 19-inch wheels and options such as Active Steering and Active Roll
Stabilization. With either xDrive all-wheel-drive or traditional rear-drive,
the 5 Series sets the standard for handling, ride and braking for the class.
BMW’s
inline 6-cylinder engines: Class-leading distinction, performance and
efficiency
• Unparalleled smoothness and
sound
• A distinction from the
multitude of V-6 engines on the market
Almost all vehicle manufacturers of 6-cylinder
engines have adopted the V-6 format, whose compactness is advantageous in small
or midsize cars with front-wheel drive. By contrast, BMW’s inline 6-cylinder
engines are outstanding for their smoothness and sound, and BMW customers
treasure them for these attributes. Thus BMW retains the inline format while developing
it toward reduced weight, more compact dimensions – and ever more brilliant
performance, smoothness and sound. An increase in fuel efficiency and even
tighter control of emissions were also set as goals for this BMW engine
generation, which currently powers the 2008 528i/xi 6-cylinder models.
N52
engine: magnesium/aluminum composite construction and Valvetronic variable
valve lift
As the “base” level powerplant,
the N52 engine offers a wide variety of benefits in the 528i and 528xi Sedans.
In addition to offering a further development of BMW’s traditional inline
6-cylinder engine, the aluminum/magnesium composite construction reduces weight
compared to an all-aluminum design, which also enhances weight distribution.
The Valvetronic
variable valve lift improves performance and fuel efficiency, while detail
refinements such as an electric water pump and volume-controlled oil pump also increase
efficiency. The result is an engine that retains the legendary smoothness of BMW’s
inline 6-cylinder engines, while offering an outstanding balance of performance
and fuel efficiency.
Compared to the previous M54 6-cylinder, the N52
offers a wide variety of benefits:
• Higher revving ability. The “redline” is
7000 rpm, vs. 6500 for the M54.
• Reduced weight – 22 lb. less. Had BMW
engineers developed the previous engine to meet their goals, it would have
added about 30 lb. – and thus would have weighed fully 52 lb. more than the new
engine does.
• More compact – Because there is just one
external drive belt, vs. the previous two, overall engine length is about an
inch shorter. Here are details of how this dramatic progress was achieved –
over an engine that was already outstanding in all these respects:
Evolved Valvetronic variable valve lift. This exclusive, patented
innovation, enhancing the performance and fuel efficiency of BMW’s V-8 and V-12
engines since 2002, varies valve lift to control engine power, dispensing with
a conventional throttle. Valvetronic enhances engine power, torque and
efficiency. Compared to the original Valvetronic system, introduced on BMW’s
V-8 and V-12 engines in 2002, the N52 engine’s 2nd-generation system benefits
from several evolutionary improvements:
• Maximum engine speed increased by 500 rpm. Enabled
by making Valvetronic’s reciprocating parts more rigid.
• Maximum intake-valve lift increased from 9.7
mm to 9.9 mm, which contributes to the increase in maximum power output.
• Greater maximum intake-valve acceleration. Less
time is spent opening and closing the valves; thus they are effectively open
longer.
• Phasing of the two intake valves. Starting
from minimal intake-valve lift (i.e. idling), an increase in engine load causes
the lift and timing of intake valve 1 to increase faster than that of valve 2.
At its maximum, this phasing has valve 1 lifting 1.8 mm more than valve 2; at
about 6 mm, the two valves are again “in synch.” This refinement enhances fuel
economy under low-load driving conditions.
Improved combustion chambers. Subtle refinements to the
combustion-chamber shape conspire with the intake-valve phasing to create more
stable combustion, with benefits to fuel efficiency and emission control.
Further evolved VANOS. Double VANOS 1 is
a familiar feature of all current BMW engines. The range over which
intake-valve timing can be varied has been increased by 10ş, achieving yet
another de-throttling effect.
Higher fuel-injection pressure results in an improved
injection spray, helping reduce raw hydrocarbon emissions in a cold engine.
All-new engine electronics. Among many innovative
details, the basic ignition and valve timing functions are duplicated. The
first part was optimized for fuel consumption and emissions; the second part
was determined according to pure driving parameters. Depending upon how
perfectly the engine is running at any time, control interpolates between the
two strategies. Under ideal conditions, the engine always runs with its lowest
possible fuel consumption. In case of poor fuel quality or unfavorable
environmental conditions, the control parameters prioritize driveability. With
introduction of this latest version, the engine’s electronic control module has
been upgraded in calculating capability and renamed from MSV70 to MSV80.
Magnesium/aluminum composite construction. An important innovation – a
world’s first in modern times and exclusive to BMW. Structurally, the new
engine block consists of three major castings:
• Bedplate (magnesium alloy [3]).
The lower portion of the block (crankcase); similar in concept to a
construction element found in some racing engines as well as the M5 and M6’s
500-hp V-10. The bedplate combines with the upper crankcase to form the block’s
outer shell; the result is an ultra-rigid engine structure.
• Upper crankcase (magnesium alloy). Joining
the bedplate at the level of the
crankshaft (main) bearings, this too is a
weight-saving casting. It is mounted onto
the bedplate from above.
• Insert (silicon-impregnated aluminum alloy,
or Alusil). In this sense, the N52’s construction resembles that of current BMW
V-8 and V-12 engines, though these blocks are all-Alusil.
In addition to the
magnesium construction, other weight-saving materials include hollow
camshafts, saving
a remarkable 2.6 lb. each. Beginning as steel tubes, the camshafts are shaped
in a hydroforming procedure, subjected from the inside to a water pressure of
58,000 lb./sq in. against outer forms to achieve the cam profiles. The engine’s
camshaft cover is of a new, weight-saving plastic material. (On earlier
N52 engines, it was of magnesium.) And the chain camshaft drive, a
high-durability, low-maintenance feature of all current BMW engines, has an aluminum
chain tensioner that also saves weight. As a final weight-reducing element,
the exhaust headers’ flanges are formed from 2-mm-thick steel,
significantly lighter than the 12-mm flanges used in the M54.
Electric water pump, electronically controlled according to
coolant and oil temperatures at any moment. It runs only as much as needed, and
in doing so consumes a maximum of 200 watts vs. up to 2 kilowatts (10 times as
much) for a conventional pump. The electric pump has numerous tangible
benefits:
• By requiring less power, contributes to the
engine’s increased power output.
• Faster engine warmup, because it doesn’t circulate
coolant when the engine is cold.
• Provides coolant circulation for the Heat-at-Rest
feature now included in the climate control.
• By eliminating an external drive belt, makes the
engine shorter.
Variable-volume oil pump. To supply pressure to the
VANOS 1 at all speeds and temperatures without excess capacity at
high engine speeds, BMW engineers developed a new type of oil pump with these
advantages:
• Contributes to the engine’s increased power output,
by requiring less power from
the engine.
• Doesn’t require a bypass to divert excess flow,
which can be up to 80% with a conventional pump. This also avoids possible
excess oil temperatures and oil foaming.
Oil/coolant heat exchanger. Another feature that speeds
engine warmup; during this phase of operation, it transfers heat from the coolant
to the oil circuit. Under conditions of high engine power and high oil
temperatures, it performs the reverse, transferring heat from the oil circuit
to the coolant, from which the engine cooling system then removes excess heat.
Additional power for 2008
While those traits
illustrate the improvement over the previous-generation BMW inline-6, the N52
engine also benefits from additional power enhancements for 2008. Compared to its most direct
predecessor, the 215-hp 525i/xi engine of 2007, the 230-hp 528i/xi engine
delivers a tangible performance boost:
528i vs. 525i –
• 0-60 mph in 6.5 sec. for the 528i Sedan with manual
transmission, compared to the ’07 525i Sedan’s 7.3 sec. (In fact, the new 528i
nearly matches the 2007 530i from 0 to 60 mph, 6.5 sec. vs. 6.4!)
• 0-60 mph in 7.1 sec. with automatic transmission,
vs. 7.6 sec.
528xi vs. 525xi –
• 0-60 mph in 7.1 sec. for the 528xi with manual
transmission, vs. ’07 525xi
• 0-60 in 7.6 sec. with automatic transmission, vs.
8.2 sec.
N54 engine: twin turbocharging, piezo direct fuel
injection, high
compression
ratio
As BMW’s other approach to modern 6-cylinder power,
the N54 is as innovative as the N52 engine, though these different innovations are
aimed at further increasing performance. A pair of relatively small
turbochargers boost performance significantly, but minimize the traditional
turbocharging response lag (“turbo-lag”). In addition, high precision direct
fuel injection further enhances performance and fuel efficiency. Finally, high-tech
heat-resistant materials in the engine help facilitate performance. With the
N52 naturally aspirated engine and this even-newer N54 turbocharged unit, BMW
is announcing to the world its approach to high performance: Instead of
ever-larger engines, BMW will achieve its performance goals with smaller,
lighter, more efficient and cleaner-running engines.
First: the 300-hp N54 engine is anything but simply a
turbocharged version of the 230-hp N52. Several new “core” features distinguish
it from the N52 and facilitate the higher performance level:
• All-aluminum structure. As attractive as the
magnesium/aluminum concept is for saving weight, the extra strength of all
aluminum construction was deemed necessary for the increased power and torque.
Some, but not all, of the mag/alu construction’s weight saving was lost. Like
the N52’s, the N54 block is a completely new construction, with bedplate.
• Cast-iron cylinder liners. Whereas the N52
has an aluminum-silicon cylinder casting inside its magnesium crankcase, the
N54 has cast-iron sleeves inside its aluminum crankcase.
• Different bore and stroke. The bore has been
reduced from 85.0 to 84.0 mm; the stroke is increased from 88.0 to 89.6 mm.
This gives greater cylinder-wall thickness – again to handle the higher
stresses within the engine – but leaves the engine’s displacement essentially
unchanged at 2979 cc vs. the N52’s 2996 cc. Both round off to 3.0 liters.
• Conventional valvegear. In the research and
development that led to the N54 engine, BMW’s engineers found that
Valvetronic’s variable intake-valve lift did not lend its advantages to the
turbocharged engine. They remain valid for the non-turbo engine.
• Moderately increased weight. Naturally, the
aluminum construction, iron cylinder liners and turbochargers add some weight
to the N54; so do solid camshafts, compared to the N52’s hollow ones.
Altogether, the N54 weighs 419 lb., vs. the N52’s 357. With this moderate
weight increase, of course, come 70 more horsepower and those 300 lb-ft. of
torque; BMW engineers point out that a 4-liter engine of this performance would
weigh a good 150 lb. more!
The performance-enhancing technologies.
Now, here are the technologies and features that
actually produce the dramatically increased power and – especially – torque
that characterize the new N54 engine:
Twin turbochargers. Turbocharging is a familiar
form of increasing the performance of combustion engines – it has been around
in various forms for 100 years. At various times, BMW has set milestones in the
development of turbocharging: in 1973, the 2002 Turbo offered 170 hp, vs. 130
for its non-turbo stablemate the 2002 tii. In 1983, a BMW powered Brabham
racecar was the first turbocharged vehicle to win a Formula 1 championship.
Yet over its history, turbocharging has also suffered
some daunting drawbacks. If, as was usual, a single turbo was used, it often
had an unacceptable degree of “turbo lag” – the lag between the time the driver
mashed down the accelerator pedal to the time when the turbo responded. This
was at its worst at low engine speeds. Another was relatively high fuel
consumption. And finally, the available materials didn’t always fare well under
the high-heat, high-rpm operation of a turbocharger, which gets its energy from
hot, flowing exhaust gases and typically spins well past 100,000 rpm. After the
2002 Turbo, which ironically was introduced just about the time of the first
international energy crisis, BMW set turbocharging aside. (Except for diesel
engines, where turbocharging is a highly conventional, almost indispensable,
power enhancer.)
The N54 turbocharging concept addresses both turbo
lag and durability concerns. By utilizing two small turbos – each one serving
three cylinders – BMW has reduced the inertia that creates turbo lag. To quote
Dr. Burkhard Göschel, BMW’s Board Member for Engineering, turbo lag “has now
become a thing of the past. The engine is agile, and it performs like a big,
naturally aspirated engine, but with much better mileage.”
Materials progress, always a factor in advancing the
capabilities of engineering and technology, figures here too: BMW has drawn
upon innovative and heat-resistant materials from space technology to
facilitate the twin turbos’ dramatic contribution to performance. All turbo
components subjected to the most extreme heat (i.e. the exhaust stream) are
made of advanced steels that can withstand up to 1050şC, or 1920şF.
Direct fuel injection with piezo injectors. Fuel injection, as we have
(mostly) known it over the decades in which it has become a feature of all
contemporary automotive engines, has been of the port type: the fuel is
injected into the engine’s intake ports, where air passes through on its way to
the cylinders. Direct fuel injection sprays fuel directly into the cylinders,
or more precisely the combustion chambers. If this were as simple as it sounds,
direct injection would long since be commonplace. But the cylinder is a much
hotter, higher pressure place than the intake port and poses big hurdles for
the fuel injectors and the optimization of just how, when and how much fuel is
squirted in. Until now, the only BMW gasoline engine with direct injection has
been the 760Li V-12 engine, where this technology brings advantages in fuel
efficiency, power, torque and emission control.
The N54’s direct injection is a 2nd-generation
evolution of the 760Li’s system, and a key factor in achieving BMW’s goals for
this engine. Its main advance over the 1st-generation system is that it gives
the engineers greater degrees of freedom in the calibration of fuel quantity
and timing and the distribution of the fuel-air mixture in the combustion
chamber. With this concept, it’s possible to utilize a “leaner” mixture – thus
less fuel. The advantages in fuel efficiency, power, torque and emission
control are more significant.
A further advantage to torque and fuel consumption is
the cooling effect of fuel being injected into the hot combustion chambers.
Typically, to avoid overheating, turbochargers have had to make do with a lower
compression ratio. That ’73 2002 Turbo, for example, had a low 6.9:1 ratio, vs.
the non-turbo 2002 tii’s 9.5:1; a more contemporary example is the Volvo S60
2.5 Turbo engine’s 9.0:1 compression ratio vs. it’s non-turbo counterpart’s
10:3:1. As a higher compression ratio benefits both fuel efficiency and
(especially low-speed) torque – traditional turbo engines have suffered on both
counts – the N54 benefits mightily: its compression ratio is 10.5:1, almost
exactly the same as the non-turbo N52’s 10.7:1!
Positioned centrally in the combustion chambers for
optimum combustion, the injectors – those critical components that inject the
fuel into each cylinder’s combustion chamber – are subject to especially high
temperatures. A new-type piezo injector is another essential element in attaining
the ambitious performance/efficiency/emissions goals with the necessary
long-term durability: A “stack” of piezo crystals reacts lightning-fast to
impulses from the engine electronics, governing the injector needle’s opening
stroke and duration for ultra-precise control of fuel quantity.
According to researchers who led the piezo injector’s
development, alone it contributes 2-3% fuel savings and 20% less emissions. Its
operating principle involves applying mechanical pressure to a non-conducting crystal
to produce an electrical impulse; in turn, this impulse is so fast that it
significantly reduces the injector’s response time.
Air-to-air intercooling. Turbocharging typically
includes intercooling of the engine’s induction air, that is, some method of
cooling the compressed air that emerges, heated up by the compression process,
from the turbocharger(s). Sometimes it’s done with coolant; in this case it’s
done indirectly by outside air. Intercooling is desirable, even necessary, to
reduce the temperature of incoming air to help preclude detonation or
“knocking” that can reduce power or, in the extreme, damage the engine. Of
course the N54, like the N52 and all other current BMW engines, has knock
control.
High-rpm concept. This is shared with the N52 engine, and also
contributes significantly to the engine’s performance character. Like the N52,
the N54 has a 7000-rpm redline. Its maximum power occurs at 5800 rpm – actually
lower than the 530i’s 6600 and the new 528i’s 6500 rpm – but power stays high
and vigorous well toward that 7000 rpm.
The bottom lines. The peak power of 300 hp has already been
mentioned; this is fully 45 higher than the 530i, and 70 hp up on the 528i. The
torque increase is just as impressive: 300 lb-ft., vs. the 530i’s 220 and
528i’s 200. At least as important is the fact that this engine can deliver its
peak torque all the way from 1400 rpm (not far above idling!) to 5000 rpm.
Finally, 300 lb-ft. is significantly better than competing 3.5-liter non-turbo
engines deliver: Lexus GS 350, 274 lb-ft. at a high 3600 rpm; Infiniti M35, 268
lb-ft. at an even higher 4800 rpm. Compared to the 528i’s 200 lb-ft., the N54’s
300 lb-ft. is fully 50% greater. BMW engine engineers assert that to achieve
this kind of torque increase, it would have taken a 4-liter naturally aspirated
engine. That would have weighed too much and its fuel consumption would have
been unacceptably high. For this reason, say the engineers, “we did not take
that path.”
One BMW engine engineer, Udo Lindner, goes so far as
to assert that the N54 has “the torque of a diesel but the revving capability
of a gasoline engine.” Diesels, currently very popular in
The other bottom line, surely the most important to
performance enthusiasts, is dramatically quicker acceleration compared to their
predecessors:
535i
• 0-60 in 5.7 sec. with automatic transmission, vs.
6.6 sec. for the 530i
535xi
• 0-60 in 5.6 sec. with automatic transmission, vs.
6.9 sec. for the 530xi
535i Sports
Wagon:
• 0-60 in 5.8 sec. with automatic transmission, vs. 7.3
sec. for the 530xi Sports Wagon
With their standard manual transmissions (SOP 09/07),
all these pairings will offer comparable improvements. As in all 5 Series cars,
top speed is electronically controlled at 150 mph.
The
550i’s V-8
The
550i’s predecessor was widely acclaimed by most who drove or tested the 545i, not
merely for its strong, fuel-efficient power, but also for its highly pleasing
sound. Car and Driver (May ’04) summed it up as “among the friendliest, most
enthusiastic engines in existence.“
With 4.8
liters, the 550i’s V-8 delivers brilliant performance. Peak power is 360 hp; likewise,
peak torque is 360. With its standard 6-speed manual transmission the 550i
attains 60 mph in just 5.4 sec. from rest; with automatic, the new model does
0-60 in 5.5 sec.
Aside from such impressive
test data, this evolution pays off in real-world performance, as media critics
have found in their test drives:
• Edmunds.com, posted March 21, ’05: “It’s refined and athletic like
the old 4.4, but its torque band seems to go on forever.”

Just what BMW had in mind.
Dynamic
Stability Control:
remarkable
new braking functions
All BMW
models are standard-equipped with Dynamic Stability Control, which provides a
wide range of traction and stability functions.
While
retaining all the functions or the previous DSC, a revised system appeared in
the 5 Series and other BMWs in 2006. This Enhanced DSC adds a wide array of
customer-relevant functions that make driving even safer and more pleasant.
They are:
• Brake
Fade Compensation. Brake fade occurs as the brakes
heat up under hard use; a given degree of deceleration requires more pressure
on the brake pedal. As brake temperature rises, this function automatically
compensates by increasing the hydraulic pressure relative to pedal force.
• Brake
Standby. When the driver lifts off the
accelerator pedal abruptly, DSC recognizes that sharp braking may be about to
occur and applies just enough pressure in the brake system to snug up the pads
against the rotors. Thus by the time the driver’s foot reaches the brake pedal,
the lag time normally resulting from bringing the pad to the rotor is
eliminated, reducing stopping or deceleration distance.
• Brake
Drying. Acting on input from the rain
sensor (an element of the standard rain-sensing windshield wipers), the pads
are periodically brought up to the rotors – just enough to eliminate any film
of water between pads and rotors, but not enough to cause a brake application.
• Comfort
Stop. Especially with an automatic transmission,
unless the driver consciously eases off on the brake pedal, a jerk can occur as
the vehicle comes to a stop. Comfort Stop eases off, making for smoother stops.
Currently only in the rear-wheel-drive models.
• Start-off
Assistant. Briefly holds the vehicle when
the brakes are released while stopped facing uphill. The driver can then start
up without doing a ballet with the clutch, brake and accelerator (manual
transmission) or rolling backward on a steep hill (automatic transmission).
• Modulated
ABS function. “Analogized” control of the DSC
brake valves makes the anti-lockup function (ABS) smoother. Instead of simply
being fully on or off, application and release of these valves are now
modulated.
Character of the 5 Series:
the
essence of sport and luxury
Long
one of BMW’s true core products, the 5 Series elegantly defines the middle of
the line with compact exterior dimensions, ample interior space and a
masterfully calibrated blend of sport and luxury. Appearing in ’04 in its
current generation, the Series maintained trim exterior size while increasing
interior space and introducing new technologies – including an aluminum
front-end structure, available Active Steering and Active Roll Stabilization,
evolved suspension and a further developed iDrive control system.
That
the current generation carries on the 5 Series tradition brilliantly is
supported by this quote from Motor
Trend’s March ’05 issue: “Here’s a thoroughbred, the product of decades of
setting the benchmark all other automakers’ sport sedans aspire to. Just look
at the stance, the way the body sits on the chassis, ready to pounce on any
opportunity to show its stuff on a challenging stretch of road. The smoothness
and flexibility of BMW inline-sixes are legendary, and the 225 horses of the
2979-cc engine seem more spirited than
their numbers might otherwise suggest. And BMW is one of the only automakers
courageous enough to offer a 6-speed manual gearbox in a $50,000 sedan.”
With
even more powerful engines, available xDrive and the new Sports Wagon to extend
its capabilities, the 5 Series is today’s representative of this fine
tradition.
State-of-the-art safety and security features
In terms of safety and
security, the 5 Series is a state-of-the-art vehicle from a state-of-the-art
vehicle maker. With an extensive array of standard features, and such available
options as the new Lane Departure Warning system, Night Vision and Head-up
Display, the 2008 5 Series remains an industry leader and fully representative
of BMW’s safety values. Key standard features include:
• Dual front-impact Supplementary Restraint System (SRS) with
dual-threshold deployment, 2-stage Smart Airbags – optimized for shape and
deployment characteristics.
• Front safety belts with automatic tensioners and force limiters –
standard on all models.
• Rear safety belts with automatic tensioners – included with the
optional rear-seat side-impact airbags.
• Automatic-locking retractors (ALR) on all passenger safety belts for
installation of child restraint seats.
• LATCH attachments at the outboard rear seating positions for child
restraint seats.
• Front-seat side-impact airbags – standard.
• Rear-seat side-impact airbags – optional at nominal extra cost, so
that customers can make their own choice in this matter.
• Head Protection System – front-to-rear via BMW’s Inflatable Tubular
concept; a long airbag deploys from the ceiling, suspended on a “sail.”
• Active front head restraints – included with the front Multi-contour
seats that are optional in all 5 Series models. Responding to impact sensors at
the rear of the vehicle, the head restraints instantly pivot forward into close
proximity with the occupants’ heads. Thus occupants are able, if they prefer,
to adjust the restraints away from direct contact with their heads, yet gain
optimum protection against whiplash or more serious head/neck injuries.
• Energy-absorbing padding of body-pillar and roof areas – specific
padding at the A-, B- and C-pillars as well as along the roof above the doors.
• Fuel-tank design and location. Not only is the fuel tank designed
to remain sealed even in severe impacts, its location has been chosen to
provide optimum protection from impacts.
•
• Automatic fuel-pump shutoff upon severe accident impact. In
addition, the doors are automatically unlocked; the interior lighting and 4-way
hazard flashers are switched on. Thus even after an accident, BMW’s safety
strategy is still at work.
• Coded Driveaway Protection – BMW’s rolling-code engine immobilizer.
• Central locking system with double-lock feature. When the vehicle
is locked from the outside, the double-lock feature prevents individual
door-lock buttons from being pulled up; thus even if a thief has broken into the
car, it isn’t possible to open the doors. Owners, however, have access to
information on how to get out if one is locked in the vehicle from the outside.
• Alarm system with interior motion detector – standard on the 5
Series.

528i and 535i Sedans are available on 528xi
Cold
Weather Package. Combines weather- and
versatility-oriented features:
For all models –
• Heated front
seats, with variable heating balance via iDrive
• Heated steering
wheel
• Headlight
cleaning system, with retracting high-intensity liquid jets.
For 535xi Sports Wagon only –
• Ski bag.
STEPTRONIC
automatic transmission – 6-speed, like all 5
Series transmissions.
Sport Automatic
transmission – 535i and 550i Sedans only;
requires the Sport Package. An even sportier alternative to the standard STEPTRONIC Sport setting, this 6-speed transmission offers crisper gearshifts
in manual mode, and paddle shifters on the steering wheel. A leather boot
around the console shifter also distinguishes this transmission from the
standard STEPTRONIC.
Lane Departure Warning. A camera mounted on the windshield near the rearview mirror
monitors lane position at all times at highway speeds. The central control unit
projects the vehicle’s path based on that position. When the system projects
that the vehicle will drift out of the lane, it will warn the driver by
producing a mild vibration in the steering wheel. The warning is cancelled by
the use of the turn signals, brake actuation, or below approximately 35 mph,
indicating city traffic. The system can also be turned off via a switch on the
multi-function steering wheel or in the iDrive menu.
Active Cruise Control. Employing a radar sensor unit at the front of the vehicle,
ACC senses the speed of vehicles traveling ahead, adjusts the BMW driver’s
speed to maintain following distance, and offers the driver additional control
choices over the standard cruise control. 2008 adds a Stop & Go feature,
which allows use in heavy traffic. The system can come to a complete stop and
remain active; a touch of the accelerator pedal by the driver reactivates the
cruise control so it can resume the set speed.
Active Steering. Offered on RWD models only; offers unique benefits:
• Widely variable
steering ratio; steering-wheel movements for parking maneuvers, U-turns and
sharp corners are greatly reduced for amazing agility. With increasing vehicle
speed, the steering becomes “slower,” favoring stability over agility.
• Vehicle
stabilization; in critical situations, can intervene to preserve stability. For
example, if the driver applies the brakes while driving on a surface with
uneven traction (one side of the road slick, the other grippy), Active Steering
can recognize incipient instability and steer against it.
Park Distance Control employs ultrasonic sensors in the front and rear bumpers
to detect obstacles not be visible to the driver; emits an acoustic warning.
Includes a vehicle diagram in the iDrive display, which graphically depicts
obstacles’ locations. Standard on 550i.
Xenon Adaptive headlights
with auto-leveling and low-speed cornering lights. Stronger, daylight-like illumination; headlights “steer” to
enhance the driver’s view around curves and corners. This year adds low-speed
cornering lights in the inboard headlamps, which illuminate nearby objects at
speeds below 25 mph. Optional on 528i/xi models, standard on 538i/xi models and
550i.
Leather upholstery – though included in the Premium Package, also available
as a stand-alone options. Standard on
550i.
Light Poplar wood interior
trim. The Light Poplar offers the same
attractively grained wood as the standard Dark Poplar, but with a more subtle
effect.
Bamboo wood interior trim. Another distinctive wood grain, Bamboo provides an especially
distinctive and contemporary look, harmonizes well with all interior colors,
and is an eco-friendly, renewable resource.
20-way front Multi-contour seats. In
addition to the standard seats’ 10-way power adjustments, the 20-way power
adjustments of these remarkable and comprehensive luxury seats include –
• Thigh support
• Angle of articulated
upper backrest section, independently from overall backrest angle
• Backrest width
(the backrests’ side bolsters spread or narrow to accommodate the occupants’
back and shoulders)
• 4-way power
lumbar support, which is standard in the 535i/xi models and 550i.
Split
folding rear seats and ski bag for the Sedans.
Heated
front seats as a stand-alone option.
Heated rear seats, available for all models in combination with the Cold
Weather Package.
BMW On-board Navigation
System. The standard iDrive system has a
6.5-in. control display (color monitor) at dash center and a turn-and-push
controller between the front seats. This option includes an 8.5-in.,
higher-resolution control display plus:
• GPS Navigation
with DVD database
• Standard
controller, plus Voice Command activation of features
• Real Time
Traffic Information, which provides up-to-the-minute information on traffic and
road conditions
Head-up Display – displays important driving-related information on a 6 x
3-in. field in the windshield, just below the driver’s normal line of sight to
the road ahead:
• Check Control
and On-board Computer warnings, prioritized according to their urgency, such as
vehicle defects, engine-oil level, low windshield-washer fluid
• Navigation
instructions
• Cruise-control
set speed (standard or Active Cruise Control)
• Current vehicle
speed.
Logic7 premium stereo. The optional Logic7 premium
audio system delivers audiophile-quality sound via a digital Surround Sound
process, utilizing 13 high-quality speakers, Digital Sound Processing and
increased audio power.
Sirius Satellite Radio. Appealing path to
entertainment, news and information channels. After the first year of
ownership, a subscription fee is required for Sirius service.
High-Definition Radio. Offers enhanced digital
sound quality; FM reception becomes CD quality while AM reception becomes
equivalent to analog FM reception. There are over 1,000 radio stations
nationwide that currently offer high-definition broadcasts.
iPod/USB adapter. A separate USB adaptor for
iPods or MP3 players, which does not use the CD changer connections, provides a
convenient audio connection.
Power rear-window and manual rear side-window sunshades. For the Sedans, the option
includes both; for the Sports Wagon, only the side-window shades. The power
rear-window shade is controlled from a console switch; the side-window shades
are easily raised or lowered by rear-seat passengers.
