Audi to unveil new S models at Frankfurt fair
Dubai, September 6, 2011
Audi will present its new S models powered by a new four-litre, twin-turbo V8, for the first time at the upcoming 2011 Frankfurt Auto Show (IAA).
The S6 and S7 use the 420 hp version of the new 4.0 TFSI. The twin-turbo V8 provides a constant 550 Nm of torque from 1,400 to 5,300 rpm. It accelerates the S6 and S7 from 0 to 100 km/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 520 hp and delivers a constant 650 Nm of torque between 1,700 and 5,500 rpm.
The sprint from zero to 100 km/hr takes just 4.2 seconds. With all three models, the electronically governed top speed of 250 km/hr 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 9.7 liters per 100 km.
The S8 averages just 10.2 liters per 100 km, much less than its competitors and a decrease of nearly 23 percent to the previous model despite a 70 hp increase in output.
The 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.
The hybrid aluminium 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 aluminium, saving around 100 kilograms 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.
New to the S family is the parking system with 360-degree 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 maneuvering 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 in summer 2012. – TradeArabia News Service
