The Audi S6 and S6 Avant use the 309 kW (420 hp) version of the new 4.0 TFSI. The twin-turbo V8 provides a constant 550 Nm (405.66 lb-ft) of torque from 1,400 to 5,300 rpm. It accelerates the S6 from 0 to 100 km/h (62.14 mph) in 4.8 seconds and the S6 Avant in 4.9 seconds. With both models, the electronically governed top speed of 250 km/h (155.34 mph) is just a formality.
Various advances add to this top result, including the recovery and begin stop frameworks and in addition the new "chamber of interest" barrel administration framework. At the point when the V8 deactivates four chambers under part stack, the Active Noise Cancelation framework (ANC) is initiated. Four receivers incorporated into the featuring record the commotion in the lodge, which is then broke down by a PC. On the off chance that the PC recognizes meddling sound components, it shows an antiphase sound's through the sound speakers framework. This sound consolidates with the meddlesome sound and to a great extent counteracts it.
Improving decorates are accessible in a decision of four materials. Matt brushed aluminium is standard, with carbon, fine grain slag regular chestnut or layered Beaufort oak as choices. Clients can look over three hues - dark, lunar silver and goa beige (just for the seat upholstery) - for the featuring, instrument board, cover and seats. The standard seat upholstery is a blend of Pearl Nappa calfskin and Alcantara, with Milano and Valcona accessible as alternatives.
