Audi presented its new S models for the first time at the 2011 Frankfurt Auto Show (IAA). The new Audi S models are powered by a new engine – a four-litre, twin-turbo V8, which combines ample power with low fuel consumption in keeping with the times.
The S6 and S7 use the 420hp version of the new 4.0 TFSI. The twin-turbo V8 provides a constant 550Nm of torque from 1,400 to 5,300rpm.
It accelerates the S6 and S7 from 0 to 100km/h in 4.8 seconds and 4.9 seconds respectively. The Audi S8 is the new head of the Audi S model family. Its new 4.0 TFSI generates no less than 520hp and delivers a constant 650Nm of torque between 1,700 and 5,500rpm.
The result is outstanding performance: The sprint from zero to 100km/h takes just 4.2 seconds. With all three models, the electronically governed top speed of 250km/h is just a formality.
The 4.0 TFSI brings Audi’s downsizing strategy to the high-performance class. The new S6 for example offers even sportier performance compared to the engine in the previous model while reducing fuel consumption by as much as 25 per cent.
Average fuel consumption in the S6 and S7 is just 9.7ltrs per 100km. The S8 averages just 10.2ltrs per 100km, much less than its competitors and a decrease of nearly 23 per cent to the previous model despite a 70hp increase in output.
Behind the top values for the new Audi S Models are the combined technologies of the Audi modular efficiency platform, including the recuperation and start-stop systems.
A newly-developed ‘cylinder on demand’ technology plays a particularly large role. Under part load, it deactivates four of the eight cylinders for an efficiency gain that is particularly pronounced at moderate highway speeds. A package of acoustic measures including the active noise cancellation system suppresses possible intrusive noise and vibrations.
Much of this groundbreaking efficiency can be attributed to the vehicles’ lightweight body.
The hybrid aluminum construction of the S6 and S7 weighs roughly 15 per cent less than a comparable all-steel body. The ASF (Audi Space Frame) is made almost entirely of aluminum, saving around 100kg compared to a conventional steel construction. The Audi ultra-lightweight construction allows weight to be reduced in other areas as well, such as the chassis.
The new Audi S6, S7 and S8 shine with craftsman-like fit and finish, generous standard equipment and a range of high-end equipment options. Subtle yet eye-catching details on the exterior and interior signal the top position in the model series.
New to the S family is the parking system with 360° camera. Four small cameras record images of the sedan’s immediate surroundings and a computer splices them together.
The driver can call up a variety of views on the MMI monitor, including a virtual top-down view. The system enhances safety while manoeuvring and in narrow driveways. Special views allow the driver to see cross-traffic.
The new Audi S models will be launched in the Middle East next summer.
