The Audi S8, treatment malady which will be launched on the market in early summer 2012, vcialis 40mg is the new head of the sporty Audi S model family. It will start at 111,900 euros.
Powered by a newly developed 4.0 TFSI develops 382 kW (520 hp), the new generation S8 consumes just 10.2 liters of fuel per 100 kilometers (23.06 US mpg) according to the automaker, while the body weighs just 231 kilograms.
The 4.0 TFSI accelerates the S8 from zero to 100 km/h (62.14 mph) in 4.2 seconds. Compared to the engine in the previous model, the normally aspirated 5.2-liter V10, the twin-turbo V8 develops 51 kW (70 hp) or around 15 percent more power, yet consumes 3.0 liters less fuel per 100 kilometers (23 percent).
The S8 comes standard with a sport-tuned adaptive air suspension. The luxury sedan’s ASF (Audi Space Frame) body is made almost entirely of aluminum. Only the B-pillars are made of ultra-high-strength steel.
A number of technologies debut, such as a new active noise cancellation (ANC) system, which is used to suppress engine and wind noise. Subtle styling tweaks include polished aluminium-look door mirrors alongside discreet S8 badging and huge 19-inch alloys.
The most interesting technology in the new 4.0 TFSI S8, however, is the cylinder on demand system. It is activated at low to moderate engine loads, with the upper limit between 25 and 35 percent of peak torque, or 160 and 250 Nm (118.01 and 184.39 lb-ft), depending on engine speed. Coolant temperature must be at least 30 degrees Celsius (86 degrees Fahrenheit), third gear or higher must have been selected and the engine must be running at more than idle speed, namely between 960 and 3,500 rpm.
If these preconditions are satisfied, the system closes the intake and exhaust valves of cylinders 2, 3, 5 and 8 on both banks. The V8 continues to run as a V4 with a regular firing order (1 – 4 – 6 –7), but with only two cylinders instead of four being ignited on each revolution of the crankshaft.
The S8 offers a wide choice of interior colors, inlays and seat coverings, including particularly fine Valonea leather. The leather package, a DVD changer, the convenience key with sensor-controlled tailgate release and ambient lighting round out the list of standard interior equipment.
The S8 is also equipped with the LED headlights and double glazing.
