A lithium-ion battery that stores braking energy, an electric compressor and a diesel engine with 349 hp (257 kW). And with 700 Nm more torque than any of its petrol-powered siblings of the past – V10 or V8. The latest generation of the Audi S6 has many groundbreaking features. However, it is almost a law of nature that power creates the desire for even more power. Therefore, weinstall the high-tech ABT Engine Control (AEC) unit in the new S6 TDI. In doing so, the performance increases to 384 hp (282 kW) and the maximum torque is boosted to 760 Nm. With the ABT Power performance upgrade, the sprint from 0 to 100 km/h is achieved in under 5 seconds. The Avant achieves this in only 4.9 seconds, instead of 5.1 seconds. The slightly lighter Saloon manages it just a hair faster. The six-cylinder diesel engine starts up in style with the ABT start-stop-switch-cap. Alongside the S6 Limousine and S6 Avant, the performance upgrade is also available for the S7 Sportback TDI, as the same engine is used.
