The Audi A8 L is a mild hybrid. This combination of an internal combustion engine, a 48-volt water-cooled belt starter generator, and a powerful lithium-ion battery will be available as standard for the first time. This new unit is the basis of a whole series of improvements, which are mainly characterised by greater efficiency and increased driving comfort. The Belt Starter Generator (BSG) plays a double role: It operates as an electric motor or as an alternator. In its first function, it provides a propulsion torque of a considerable 60 Newton metres. These are utilised in the Audi A8 L for a unique function: When you reach your target speed, the combustion is switched off for up to 40 seconds between 30 and 160 km/h – for comfortable, quiet, and emission-free sailing. The BSG has enough power to restart the engine at any time. You touch the accelerator pedal – and the engine immediately kicks into action. The generator even has its advantages during deceleration: together with the powerful battery above the rear axle, it enables a more intense recuperation. This way spent energy is fed back to the vehicle. In many situations, this recovery is even more efficient than the mentioned sailing - thus the A8 L drive management constantly monitors and evaluates the situation.

Each speed entails different steering requirements: while in the lower range it is about manageability, later, apart from agility, it is mainly about stability. From a technical point of view, there is also a contrast which has often led to concessions, meaning that it is always one aspect of steering or response behaviour that has become the focus. The dynamic four-wheel steering now decisively resolves this eternal compromise. It combines dynamic steering on the front and rear axle with a central control unit. Their algorithm translates the steering movement into respectively optimal wheel angles as a function of the current speed. This achieves a comprehensive handling improvement: Your steering effort is considerably reduced when turning and parking - the vehicle's turning circle is noticeably scaled down via mutual steering of the rear wheels. You can enjoy sporty mobility, and riding like on rails at up to 120 km/h. Beyond this point, the required steering angles are again reduced, leading to relaxed and stable driving behaviour on motorways.
