Special-edition A8 L W12 will be produced in a limited series of just 50 units.

Audi is calling this a concept but also says it will be produced as a limited-series edition.

This is the Audi A8 L W12 exclusive concept, powered by a 6.3 liter W12 petrol engine with 500 PS (368 kW / 493 hp) and 625 Nm (461 lb-ft) of torque.

But what's really special about this edition is the highly-refined interior finish with high-grade leathers.

The finish comes courtesy of Italian design house Poltrona Frau. The seats are upholstered in a Cognac-colored leather with highlights of granite gray piping. Wood inlays of olive ash in a light gray-brown veneer complement the additional leather finish of the dashboard, center console, door trims, seat consoles and the tunnel. Even the car's key is done-over in leather.

The sills on this special A8 come trimmed with "Audi exclusive concept" lettering. The outside of the car is painted Monsoon Gray.

Audi will make only 50 units of the A8 L W12, with each unit identified by a series number.
