The newest S models are powerful but elegant sporty cars. They are powered by a newly designed 4.0 TFSI engine, which provides 309 kW (420 hp), yet respectively averages just 9.6 or 9.7 liters of fuel per 100 km (24.50 or 24.25 US mpg) – thanks in part to new cylinder on demand technology. A sophisticated chassis, lightweight bodies and a refined interior complete the profile of these perfect new Audi athletes.
Strong performance, superb dynamics, elegant understatement and everyday practicality: the new S models by Audi combine all of these characteristics with the latest in state of the art. Its V8 engine, the 4.0 TFSI, provides 309 kW (420 hp) yet consumes just 9.6 or 9.7 liters of fuel per 100 km (24.50 or 24.25 US mpg). The cylinder on demand system, which switches off four of the eight cylinders in many driving situations, contributes significantly to this efficiency.
The new S models are sports cars for everyday life. Their twin-turbo V8 delivers 309 kW (420 hp) from a displacement of four liters while transmitting 550 Nm (405.66 lb-ft) of torque between 1,400 and 5,200 rpm. The 4.0 TFSI reacts instantaneously because the approach concerning cylinder heads – the inlet side is outside and the exhaust-gas side is inside – allows for short gas-travel paths with minimal friction losses. Two twin-scroll turbochargers ensure that considerable torque is generated faster than otherwise.
The Audi S6 accelerates from zero to 100 km/h (62.14 mph) in 4.6 seconds; the S6 Avant and the S7 Sportback each need just one-tenth of a second longer. The S6 and the S7 Sportback each averages 9.6 liters of fuel per 100 km (24.50 US mpg), while the S6 Avant consumes 9.7 l/100 km (24.25 US mpg).
The all-new cylinder on demand system, which switches off four of the eight cylinders during part-load operation, contributes significantly to this efficiency. At the same time, the active noise control (ANC) system largely counteracts unwanted noise by broadcasting targeted cancellation sounds into the vehicle interior via the sound system’s loudspeakers. Active engine mounts simultaneously offset low-frequency vibrations via countermeasures.
The seven-speed S tronic and quattro permanent all-wheel drive are standard equipment in all three new S models; the latter operates in conjunction with torque vectoring. Upon request, Audi will complement it with the sport differential, which actively distributes power between the rear wheels. adaptive air suspension sport is also standard. This suspension’s stiff setup with controlled damping lowers the vehicle body of the S7 Sportback by ten millimeters (0.39 in) and that of the S6 by 20 millimeters (0.79 in). The Audi drive select dynamics system incorporates not only the air suspension but also optional components such as the sport differential and dynamic steering. The driver can vary its operation step-by-step.
