Audi has just officially released a high-performance variant of their new flagship sedan, namely the S8. The S8 essentially fills the holes left by the original A8, with the powertrain being straight on the forefront. A Volkswagen 4-liter twin-turbo TFSI V8 is crammed into the all-aluminum Audi Space Frame, producing 520 horsepower that drags the car from zero to 60 in 4.2 seconds, and a top-speed of 155 mph. Being a German car, fuel economy is obligatorily on top of the list, with a 23 miles per gallon controlled by an eight-speed tiptronic transmission. As the outside comes in a classy understated appearance, the inside shows carbon and chrome details confidentially spread throughout the whole cabin, and a lot of features and details that wants to be discovered.
