The Audi S6 Avant in figures: V8 4.0 TFSI. Substantially lower CO2 emissions compared to its predecessor. Its 309 kW are accompanied by a mighty 550 Nm of torque and propel the Audi S6 Avant from 0 to 100 km/h in under five seconds. With innovative cylinder management, the start-stop system and a new system of thermal management, this is one high-performance athlete that can boast excellent efficiency too. It is this smarter force that endows the Audi S6 Avant with its uniquely progressive style of superlative sportiness and sensational dynamism.
Hard at work under the bonnet of the Audi S6 Avant is a 4.0 V8 TFSI engine featuring the innovative new Audi cylinder-on-demand technology. This keeps just four of the eight cylinders operating at partial throttle – without you noticing any difference. The engine continues to run smoothly and powerfully, but its fuel consumption and CO2 emissions are reduced accordingly.
This method of operation is what we call „intelligent performance“. Audi cylinder on demand selectively closes certain cylinders only, two in each cylinder band to be precise. As a result, engine operation is impressively smooth at partial loads too. Cylinder shut-off is controlled by several factors: the engine speed must be between 960 and 3,500 rpm, for instance, the engine temperature must be at least 40 °C, and you must be driving in at least third gear. If the full power of all eight cylinders is not required, the Audi valvelift system will close the intake and exhaust valves as well as shutting off injection and ignition for the relevant cylinders. In other words, no air is drawn in, fuel injected or exhaust gases discharged. Or, put another way: there is a substantial improvement in the fuel consumption and emissions figures.
The 4.0 TFSI V8 engine is additionally equipped with the economical start-stop system and meets EU5 emissions limits, of course. The unit employs the Audi valvelift system, which generates higher torque while cutting fuel consumption.
Thanks to its remarkably spontaneous response and exceptional power delivery across the entire rev range, the V8 engine also enables the car to be driven in an effortlessly sporty manner. Its 309 kW output and 550 Nm of peak torque catapult the S6 Avant from 0 to 100 km/h in 4.9 seconds. The engine is electronically goverend to a top speed of 250 km/h.
Fuel consumption and emissions value:
Fuel consumption, combined: 9.8 l / 100 km
CO2 emissions, combined: 227 g/km
