( http://www.TFLcar.com ) The 2013 Audi S8 is powered by a 4.0-liter V-8 force-fed by not one but two turbochargers. This engine is a little monster and produces 520 hp versus the previous model's 450 and get this it puts out a tire scorching  torque: 479 lb-ft of torque. Nathan recently had the chance to drive this new flagship Audi in the hills above Los Angeles and he came away more than impressed by the Audi's sheer power and handling. Check out this first drive review as Nathan spends some time behind the wheel of the new 2013 Audi S8.
