Following the general trend now, Audi has once again sent into retirement and a naturally aspirated engine with a more efficient, because weaker-displacement turbocharged engine replaced. From V10 with 5.2 liters of displacement was 4 liter TFSI V8 with twin turbochargers. The advantage is lowered by 25 percent of normal consumption.Audi S6 and Audi S7 Sportback satisfied according to test cycle of 9.6 liters per 100 kilometers, the S6 Avant 9.7 liters.
Respectable values for a 550 Newton meters brace ends 420 bhp petrol engine in a big car that can accelerate in 4.6 seconds (S6 Avant 4.7 seconds, and S7 Sportback) from the stand at highway speed. A very clever system makes its predecessor significantly lower fuel consumption.
The need for justice is once again, brought pursuant to the downsizing strategies, in the foreground. When cruising, such a big engine is rather counter-productive in terms of consumption, that is to be shut down cylinders when not just drawn from the solid. "Cylinder-on-demand" this Ingenieurskniff at Audi is called. From the third running of the 7-speed DSG and at a constant speed of 4 cylinders, the valves are not opened and the ignition and fuel injection system to be shut down. Typical application: road and highway cruising leisurely. It runs thus de facto with a four cylinder, to a demanding step on the accelerator is made. Really quite imperceptibly the engine goes back into the 8-cylinder mode. Some had to be done to make it work.
Thus resulting in a 4-cylinder mode due to the lack of ignition in the engine no vibration or noise shortcomings, Audi has dug deep into their bag of tricks. In order to obtain the riding comfort of an 8-cylinder upright in every driving situation, active engine mounts with counter vibrations for absolute freedom from vibration. For perfect acoustics, and always discreet and sonorous 8-cylinder sound is the "active noise control" responsible. Four microphones in the interior noise level to detect the unwanted frequencies. To remove this anti-noise is emitted from the speakers. It works perfectly. In our tests, we first had the onboard computer menu on the display for the 4-cylinder mode search to make sure that we find ourselves in this.
Rush is behind the wheel of the S6/S7 never. A conversation with the passenger on the performance virtues is also beyond the 200 possible tempos, without raising his voice. Typical of the "S" models - high dynamic range without any loss of comfort. This is also due to specific adaptive "Audi air suspension sport", the Audi drive select via MMI over emphasized or too easily can be dynamically tuned. You notice on brisk country road games but the tight weight of the spacious car.
Also in the interior and the design details will be given to unique, but subtle distinction to the "normal" value models. In the Audi S7 standard, the Audi S6 provide the option of built-in headrests and diamond-shaped quilted leather very valuable and exclusive sports seatjavascript:void(0)s acting for good support. For cozy interiors provide on request a special wood-aluminum rails, which are bonded complex layers. Thus equipped, the interior design is actually already in pole position. When the exterior decorated with chrome trim grille, mirror caps in aluminum look and a double-flow dual exhaust system are striking, typical "S" model features that move but still within a legitimate framework.
