LA Auto Show Live: Audi S8 and e-tron Spyder image

This year at the 2011 LA Auto Show, Audi unveiled the latest addition to the A8 lineup for United States – the S8 model. In addition, the German automaker displayed the e-tron Spyder concept.

Powered by a twin-turbo V-8 engine good for 520 horsepower and 480 pound-feet of torque, the S8 is sure to be a riot to drive. Also debuting with the new S8 is the company’s new “cylinder on demand” technology, which is synonymous to General Motors’ Active Fuel Management (formerly called Displacement on Demand) and Chrysler’s Cylinder Deactivation System.
The system saves fuel by shutting down half of the engine’s cylinders when cruising. During acceleration, the engine works at full capacity, delivering maximum power and refinement. [more about the new Audi S8]

Power is delivered to the wheels by way of Quattro all-wheel drive and an 8-speed Tiptronic transmission. The German automaker claims that despite the bump in power and performance that the new S8 is up to 23 percent more efficient than the outgoing model.

In addition, the e-tron Spyder was presented to the public. The plug-in diesel hybrid uses both diesel and lithium ion batteries and can travel up to 30 miles on electric power.

Even if that doesn’t sound too impressive you will definitely be moved by the next figures which are 4.4 and 2.2, translated into the 0 to 100 km/h sprint time of 4.4 seconds and the average fuel consumption which is 2.2 liters every 100 km, translated into “American” with 106.92 mpg, while emitting just 59 g/km of CO2.
