Designed to redefine the "pinnacle of sporty performance," the model features an upgraded twin-turbo 4.0-liter TFSI V8 engine that has been tuned to produce 605 PS (445 kW) and 700 Nm (516 lb-ft) of torque - 750 Nm (553 lb-ft) with overboost.  This enables the luxurious sedan to accelerate from 0-100 km/h in just 3.8 seconds before hitting a limited top speed of up to 305 km/h (189.5 mph).

Besides the upgraded engine, the model features a retuned adaptive air suspension, a modified dynamic steering system and carbon ceramic brakes with anthracite-gray calipers embossed with the Audi logo.  Other highlights include a carbon fiber intake surrounds, a sports exhaust system and special 21-inch alloy wheels.
