At its market introduction in Australia, the new A8 will offer two extensively re-engineered V6 turbo engines, a 3.0 TDI with 210kW and a 3.0 TFSI with 250kW. All engines offer supreme refinement, ample performance and high efficiency. The new mild hybrid technology (MHEV, mild hybrid electric vehicle) drives down fuel consumption by as much as 0.7 litres per 100 kilometres in real driving conditions. 

Audi’s MHEV technology is based on a newly developed 48-volt primary electrical system – it supplies the 12-volt system that now becomes an electrical subsystem. The 48-volt system is fed by a belt alternator starter (BAS) connected to the engine’s crankshaft by the belt drive. A lithium-ion battery positioned safely beneath the luggage compartment floor serves as the storage unit.

Thanks to the higher voltage, the new A8 can coast along silently in a speed range from 55 through 160km/h (where speed limits permit) and proceed with zero emissions for up to 40 seconds with the engine off altogether. As soon as the driver steps on the accelerator again, the belt alternator instantly restarts the engine. In addition, start/stop operation is active from 22km/h, and when the brakes are applied, the BAS can recover up to 12kW of power, again helping to reduce fuel consumption. 

In terms of ride, Audi has rethought every aspect of the chassis of its new flagship. Revolutionary technologies and control systems make it even more comfortable, sporty and safe. 

Final Australian specification is yet to be confirmed.
