Self-Study Programme 456
The Audi A8 ’10
Audi
Service Training
The Audi A8 ’10 combines excellent road holding with a high level
of ride comfort and unique design.
The Audi A8 ’10, the sportiest of the luxury saloons, clearly stands
apart from its core competitors, combining outstanding standards
of comfort and prestige with a potentially irresistible appeal.
The Audi A8 is synonymous with the innovative Audi Space Frame
(ASF) body concept, which has been systematically refined. An
intelligent, modular front and rear Crash Management System
fully absorbs the impact energy at low speed.
The occupants of the Audi A8 ’10 reside in an interior that exudes
exclusivity and sporting elegance throughout, enhanced with a
myriad of innovative details that underscore its progressive design
and quality.
The engines of the Audi A8 ’10 and the eight-speed tiptronic have
been developed specifically with a view to better fuel economy and
lower CO
2
emissions combined with higher performance.
The Audi A8 ’10 is a beneficiary of the new design direction at Audi,
which is based on the modular longitudinal platform principle. Key
changes include the redesigned kinematics and elasto-kinematics,
the set-forward front axle and reconfigured front axle compo-
nents, the steering position under the centre of the front wheel
and the upper control arm mounting integrated into the body.
The new light system and the numerous electronic control units
arising from the increased use of infotainment systems have
inspired groundbreaking new solutions in the Audi A8 ’10.
For instance, most of the control units are installed in the luggage
compartment behind the rear seat system. A FlexRay bus system
which controls data transfer by setting fixed transmission times
has been integrated into the existing vehicle network.
The standard 2+2 zone automatic air conditioning system is based
on a new air conditioner with 15 servomotors and allows separate
climate control at head and foot level. The optional four-zone
automatic air conditioning system also features a separate rear air
conditioning system.
