Audi unveils new S models
Dubai, September 18, 2012
German luxury car manufacturer, Audi, has introduced its new S models – the Audi S6, S7 and S8 – the high performance versions of its top-selling Middle East saloons.
The new S models are powered by a new engine - a four-liter, twin-turbo V8, which combines ample power with low fuel consumption, a statement from the company said.
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 5,200 rpm. It accelerates the S6 and S7 from 0 to 100 km/h in 4.6 seconds and 4.7 seconds respectively.
The Audi S8 is the new head of the Audi S model family, the statement said. 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/h takes 4.2 seconds.
The 4.0 TFSI brings Audi’s downsising strategy to the high-performance class. The new S6 offers even sportier performance compared to the engine in the previous model while reducing fuel consumption by as much as 25 per cent, it said.
Average fuel consumption in the S6 and S7 is 9.6 liters per 100 km. The S8 averages 10.1 liters per 100 km, a decrease of nearly 23 per cent to the previous model despite a 70 hp increase in output.
The newly developed ‘cylinder on demand’ technology plays a large role. Under part load, it deactivates four of the eight cylinders for an efficiency gain that is particularly pronounced at moderate highway speeds, it said. A package of acoustic measures including the active noise cancellation system suppresses possible intrusive noise and vibrations.
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 100kgs compared to a conventional steel construction, it said. 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° 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.
Fuel is provided via Audi’s FSI direct injection system. Switchable flaps in the intake ports induce a rolling type of movement in the incoming air for improved combustion.
Like almost every Audi engine, the new 4.0 TFSI also follows the principle of downsising, where forced induction replaces displacement. One turbocharger per cylinder bank compresses the intake air.
Prices start from $81,376, $91,177 and $127,940 for the Audi S6, S7 and S8 respectively including 5 years service and 3 years warranty. – TradeArabia News Service
