Sportiness meets efficiency – three new S-models from the Audi A6 and A7 series offer customers in Europe the ideal performance models for the long haul. For the first time, Audi has combined a V6-TDI engine with an electric powered compressor and a 48-volt primary electrical system. The S sport suspension with damping control, dynamic all-wheel steering and the ceramic brake system tick all the boxes for dynamic cornering and deceleration. The striking design with the sophisticated looks of an S model lends these sporty full-size models particular presence.
Audi S6 Sedan: Combined fuel consumption in l/100 km: 6.3 – 6.2(37.3 – 37.9 US mpg)*; Combined CO2 emissions in g/km: 165 – 164 (265.5 – 263.9 g/mi)*; Audi S6 Avant: Combined fuel consumption in l/100 km: 6.5(36.2 US mpg); Combined CO2 emissions in g/km: 171 (275.2 g/mi); Audi S7 Sportback: Combined fuel consumption in l/100 km: 6.5(36.2 US mpg); Combined CO2 emissions in g/km: 170 (273.6 g/mi)
* Fuel consumption and CO2 emission figures given in ranges depend on the tires/wheels used as well as the selected equipment
“Torque kick”: electric powered compressor and 700 Nm of torque
The huge torque peaking at 700 newton-meters (516.3 lb-ft) constantly available on demand to the driver across an engine speed range of 2,500 to 3,100 rpm is the ideal basis for performance-minded customers in Europe. The S TDI models offer high driving dynamics and efficiency – an especially attractive combination for long-distance driving. With the S6 and S7 TDI models Audi systematically takes the successful drive concept of the SQ7 TDI (combined fuel consumption 7.6 – 7.2 l/100 km (30.9 - 32.7 US mpg)*; combined CO2 emissions 199 – 189 g/km (320.3 - 304.2 g/mi)* to the next level. For the first time, Audi’s engineers have paired an electric powered compressor with a 48-volt primary electrical system.
This takes the three-liter V6 TDI’s total power output to 257 kW (349 hp). Power transmission is handled by the eight-speed tiptronic automatic transmission, which always operates in tandem with quattro permanent all-wheel drive.
Spontaneous helper: the electric powered compressor
The electric powered compressor delivers high starting performance. As well as very vigorous acceleration, the electric supercharger provides a repeatable boost function when accelerating. This means the EPC pre-empts any hint of turbo lag, and enables high responsiveness and powerful acceleration in every driving situation.
The EPC’s response time is under 250 milliseconds, its peak output is seven kilowatts and its maximum speed is 70,000 rpm. The electric turbocharger’s boost function extends all the way to an engine speed of 1,650 rpm. Thanks to dual supercharging, in other words the EPC working in tandem with the exhaust turbocharger, the full-siz...
