The new Audi A8 L Security
Supreme protection for passengers
- High-security version of the new A8 launched
- A8 L Security meets highest level of security criteria
- Choice of two high-end engines: V8 4.0 TFSI or W12 FSI
Launch of the most exclusive model version in Audi's new A8 car line
the A8 L Security. The high-security version of the luxury sedan meets
the highest level of criteria that apply to civilian vehicles. An
array of high-security equipment features complement the armor
plating. The new Audi A8 L Security is available with two outstanding
engines, the 4.0 TFSI and the W12.
At 5.27 meters (17.29 ft) long and with a 3.12 meter (10.24 ft)
wheelbase, the new Audi A8 L Security is a representative sedan that
is, visually, barely distinguishable from the production version. And
like its mainstream counterpart, its sporty, elegant design is now
even more expressive: The hood, the Singleframe grille and the bumper
have acquired sharper contours. The headlights have been made flatter
and the LED rear lights have been modified too. The exhaust system is
terminated by two large trapezoidal tailpipe trims on both sides of
the tail end.
LED headlights are part of the standard specification in conjunction
with the V8 engine; the W12 comes with Audi's innovative Matrix LED
technology. With these headlights, the high-beam comprises 25 small,
individual light-emitting diodes per unit that can be switched on and
off or dimmed individually as needed. The headlight system can very
precisely mask other road users out of the cone of light, without
significantly reducing illumination of the road.
When developing the A8 car line, Audi included the high-security
version in its plans right from the outset, resulting in an integral
overall concept that is far superior to retrofit solutions. The
deformation properties of all key components were investigated to
ensure the new A8 L Security exhibits excellent crash behavior which
also seeks to minimize the impact on the other party. Complete with
its quattro permanent all-wheel drive, it is still the lightest luxury
sedan in the high-security segment.
Its basis is a modified production body made largely from aluminum
according to the Audi Space Frame (ASF) principle at the Neckarsulm
plant, the home of the A8; as a result, it weighs roughly 40 percent
less than an equivalent body made from steel. The components that are
specific to this version are made by hand in a secure production zone.
It takes specially trained workers about 450 hours to fit them, before
the body is sent back to the plant for final assembly.
The new Audi A8 L Security has been officially certified by the German
Ballistics Testing Center in Munich; it complies with the requirements
of the class VR 7 ballistic protection standard in accordance with the
BRV 2009 guideline. BRV stands for "Bullet Resistant
Vehicles". Class VR 7 imposes the strictest criteria on civilian
high-security sedans: The body panels and glazing of the passenger
cell must withstand firing with NATO sub-caliber ammunition. In
certain areas, the armor plating on the A8 L Security even complies
with the criteria for the classes VR 9 and VR 10. Resistance to
explosives is tested in accordance with the ERV 2010 guideline
(Explosion Resistant Vehicles).
The high-security sedan's occupant cell, which is integrated into the
body as a unitary element, features extremely tough, highly resistant
materials heat-formed armor steel, aramide fabric, ceramic, a
special aluminum alloy, and multi-laminated glass. The protective
materials overlap at transitions, for maximum security.
The aluminum side sills incorporate massive ballistic-proof profiles
that afford increased protection against explosive weapons an area
in which the requirements have become considerably tougher in recent
years. The armor-plated vehicle floor made from a special aluminum
alloy has the same purpose. The new Audi A8 L Security can withstand
attack by military hand grenades. Even an explosive charge, as
specified in the test program, does not pose a lethal threat to
passengers, as demonstrated by tests involving dummies.
For the door windows, windshield and rear window, Audi uses special
glass with a splinter-inhibiting polycarbonate layer on the inside. As
an option, there are electromechanical side windows that almost fully
open the panes. A doorstop function holds the door in any desired
The communications box in the trunk of the high-security saloon is one
of its central elements. It houses the control units for the vehicle
and communications electronics, as well as a supplementary battery and
elements of the optional components that increase passenger protection
still further. The highly armor-plated communications box has
comparatively lightweight ceramic doors, and its frame is made from
aluminum. Special protection for the battery and fuel tank can also be
supplied as an option.
The standard equipment of the new Audi A8 L Security also includes the
intercom system that the passengers can use to communicate with the
outside world with the windows shut. It comprises a loudspeaker in the
Singleframe grille, along with microphones for the interior and for
the vehicle's surroundings.
Optional high-security equipment
Audi can supply a wide range of options to enhance protection in the
new A8 L Security. These include the emergency exit system, a
technology for which the brand holds the patent. If the driver or rear
passenger presses a sealed switch while pulling one of the inside door
handles, pyrotechnic fracture bolts in the hinges detach the door from
the body so that it can then be opened with a light push.
Another feature is the fire extinguisher system, which is activated at
the press of a button or by heat sensor. The extinguishing agent is
supplied through pipes on the underbody from two tanks fitted in the
trunk. Nozzles spray it into the wheel arches, onto the underbody and
tank, and into the engine compartment.
The emergency fresh-air system operates with two pressurized
cartridges housed in the protected zone. At the push of a button it
supplies the interior with breathing-quality air through vents in
most cases for long enough to drive through or out of a hazard zone.
The system generates overpressure inside the vehicle and thus prevents
infiltration by toxic gases. Another option is the security start a
feature that allows the driver to start the engine remotely by radio
Numerous additional solutions round out the offering. These include
selective unlocking of doors, a smoke extractor for the interior, an
LED signal system for convoy driving, pennant holder, flashing lights,
a siren, a preparation for or installation of analog and digital radio
networks for security authorities and organizations, a built-in phone,
an accident data recorder, an additional rear camera and a heated
windshield including partly heated side windows. Audi is also able to
meet special requests of customers.
The interior of the new Audi A8 L Security is an elegantly styled
relaxation zone offering a bespoke-standard build quality. There are
two electrically adjustable individual seats in the rear. The front
comfort seats, with an equally wide range of adjustment options, can
also be supplied with massage and ventilation functions.
On request Audi will fit the relaxation seat an extensively
adjustable front-passenger seat with electric-control footrest,
ventilation and massage function. A continuous center console with
large storage compartments is also available, rounded off by the Rear
Seat Entertainment with two 10.2-inch displays. Optional features such
as a folding table, a cool box and auxiliary heating make for an even
more pleasant trip.
The range of upholstery materials, inlays and colors available for the
interior has been revised. The highlights include the new Unicum
leather, which is especially natural and breathable. The range of
inlays offered by Audi includes poplar brown silver and fine grain ash
natural gold brown; these have a finish enhanced with silver and
bronze pigments respectively. Especially discerning customers will
find many other individual features in the Audi exclusive range.
For all its array of functions, the new Audi A8 L Security has a
clear, easily understandable operating concept. One of its central
elements is the MMI terminal on the console of the center tunnel. The
driver can control a wide range of navigation and multimedia functions
by character input using the large rotary pushbutton and a touchpad
the MMI touch.
There is a choice of two high-end engines for the new A8 L Security
the 4.0 TFSI and the W12 FSI; both are to Euro 6 emission standard.
The eight-cylinder engine with a displacement of 3,993 cc develops 320
kW (435 hp), 11 kW (15 hp) more than in its predecessor. It delivers a
600 Nm (442.54 lb-ft) of torque to the crankshaft between 1,500 and
5,000 rpm. It accelerates the new A8 L Security from 0 to 100 km/h
(62.14 mph) in 7.5 seconds. Its average fuel consumption is a modest
10.9 liters of fuel per 100 kilometers (21.58 US mpg).
The high-tech character of the V8 biturbo is manifested in numerous
details, such as the twin-scroll turbo chargers that provide for the
early and rapid development of torque, in the innovative thermal
management and in the layout of the cylinder heads. Their intake end
is on the outside and the exhaust end on the inside. The turbos and
their intercooler are located in the inner V. This layout results in
short gas flow paths with minimal flow losses and spontaneous
The twelve-cylinder engine in the new Audi A8 L Security is a
naturally-aspirated power unit. Developing 368 kW (500 hp) and 625 Nm
of torque (460.98 lb-ft), it propels the large high-security sedan
from 0 to 100 km/h (62.14 mph) in 7.1 seconds. Its top speed is
governed to 210 km/h (130.49 mph). The W12 averages 13.5 liters of
fuel per 100 kilometers (17.42 US mpg). Like the eight-cylinder
version, that is the best performance among its direct field of
The W12 engine, with a displacement of 6,299 cc, is notable for its
extremely compact layout. Its crankcase consists of four rows of three
cylinders. Two rows face each other, offset by 15 degrees, and combine
to form a single, wide bank. The two cylinder banks are arranged at an
angle of 72 degrees. The crankshaft has a crankpin offset of 12
degrees so that the twelve cylinders ignite in the ideal interval of
On both engines, an eight-speed tiptronic with a high overall spread
takes charge of the transmission. Its fully electronic control is
operated from a selector lever or by paddles on the steering wheel.
The quattro permanent all-wheel drive system distributes the power to
all four wheels. The basic setup is sporty, with a bias towards the
rear wheels; if need be, the system transmits most of the power to the
axle with the better traction.
The new Audi A8 L Security provides luxuriously smooth ride comfort.
Its chassis, brakes and electronic control systems have been specially
developed to handle the increased weight; the strength, materials and
wall thicknesses of the control arms, for example, have been
redefined. The adaptive air suspension complete with controlled
damping is incorporated into the driving dynamics system Audi drive
select, with which the driver can vary the way a whole range of
technical modules operate. As an alternative to hydraulic
rack-and-pinion steering there is dynamic steering, where the ratio is
adapted to the road speed.
The high-security sedan comes with forged 19-inch wheels as standard.
The tires have the unconventional dimension 255/70 and the high load
index 117. Polymer rings on the rims enable the vehicle to continue
traveling at a maximum speed of 80 km/h (49.71 mph) even after a
puncture. A direct-measurement tire pressure monitoring system is
likewise standard, and Audi can supply a full-specification spare
wheel as an option.
Equipment and trim
The interior of the new Audi A8 L Security presents a First Class
atmosphere as well as the luxurious seats, standard equipment items
include four-zone automatic air conditioning with an ionizer, electric
rear blinds, the Bose surround sound system and a TV tuner. The MMI
navigation plus interprets the route in advance and transmits the data
to the control units for the tiptronic, the headlights and the
optional adaptive cruise control with stop & go function. Another
standard feature is the parking system plus with surround view
The Audi pre sense safety system can reduce the severity of accidents
and their consequences in many cases. The new A8 L Security comes with
the pre sense basic version as standard, complemented by the pre sense
rear function, which is linked to the Audi side assist lane-change
assistant. Safety and comfort can be enhanced by other systems if
desired: Audi pre sense front as a component of adaptive cruise
control (ACC) stop & go, night vision assistant, and Audi lane
assist, which identifies lane markings.
The new Audi A8 L Security also leads the way in terms of multimedia
the standard-fit hardware component Audi connect including car phone
provides Internet connectivity. The system delivers tailored online
services into the car for the driver's benefit, and the passengers can
connect their mobile devices to a Wi-Fi hotspot. Separate phone
receivers are available as an option.
Orders can already be placed for the new Audi A8 L Security W12, with
deliveries starting in the third quarter of 2014. Audi provides
extensive services to support its customers and offers special
training for drivers and vehicle owners.
