Power plus efficiencyThe Audi A8 4.2 TDI

You’ll sense the sheer power of the Audi A8 4.2 TDITDISynonymous with muscular torque delivery and outstanding efficiency: TDI. Today, TDI engines are sporty, smooth and economical.TDI engine as soon as you step on the accelerator: 258 kW (350 bhp) and peak torque of 800 Nm whisk you from 0 to 100 km/h in just 5.5 seconds. Yet its consumption is only 7.6 l per 100 km.

This is largely thanks to the common rail technology, which injects the fuel directly into the piston combustion chamber at up to 2,000 bar. The TDI engine, too, features innovative thermal management that cuts fuel consumption by rapidly heating up the coolant. The engine’s weight has moreover been reduced despite its greater technical complexity.
