Lithium-ion battery

Determines the performance and operating range of the hybrid drive

train. It has 2 major advantages compared with conventional nickel

metal-hydride batteries: its high energy density means greater

power output, whilst the compact construction considerably reduces

its weight. This in turn benefits the vehicle’s luggage space – despite

the battery it has a volume of 375 litres above the loading floor.

Active battery cooling improves the availability of the hybrid system

and prolongs its operating life. Thus the Audi A8 hybrid is one of the

first cars in the luxury class to run purely on electricity with a

lithium-ion battery for a certain period.

Hybrid driving modes

The A8 hybrid can be driven purely electrically in EV mode up

to a speed of 62mph for short distances. This makes for reduced

emissions and almost silent driving. D mode is set up for optimised

fuel consumption and main drive power comes from the 2.0 TFSI

engine. The program maintains an efficient balance between fuel

consumption and performance. Features of this mode include

electric drive, gliding, start-stop, boosting and recuperation. The

boosting feature enables the electric motor to boost the combustion

engine, briefly generating additional output and torque for the

hybrid system. The S mode features sporty engine and transmission

settings and performance can be boosted by the electric motor.

Electromechanical power steering

Increases efficiency as the steering force isn’t supplied by the

engine, but is instead generated electrically when required.

e-automatic air-conditioning

Is operated by an electric air-conditioning compressor, working

independently of the engine. This means climate control is always

available – even in pure electric mode and with the engine switched

off when the vehicle is at a standstill.
