The S8 is the performance-enhanced flagship of Audi's lineup. It is based off the A8 luxury sedan and features all the cutting edge innovation that Audi has to offer.

The Audi S8 is powered by a V-10 engine, similar to the engine found in the Lamborghini Gallardo. It utilizes the Audi's quattro permanent four-wheel drive system to put all hp to the ground and a six-speed Tiptronic transmission is standard. Inside it has Valcona leather upholstery, brushed aluminum and carbon inlays, Bang & Olufsen Advanced Sound System, and ambient lighting.

The S8 is a carryover model from mid 2006.
