The promotional video provided by Audi shows the Audi in its entirety. The video allows the viewer to see the interior up close and personal as the camera zooms in. The Audi A8L W12 has a longer wheelbase with an extra 130mm of legroom which is clearly illustrated as the gentleman in the video stretches out his long legs in the back seat. Of course, we know how well Audi does with its videos considering the mini-series they have created with Justin Timberlake and Dania Ramirez which stars their newest hatchback, the Audi A1.
Back to this Audi. The Audi A8 L W12 uses a twelve cylinder engine that consists of four rows of three cylinders with a 15-degree included angle between the two offset rows of cylinders in each broad cylinder block. The engine is primed to deliver 500 hp and 460.98 lb-ft of torque at 3,250 rpm. The result is a sprint from 0 to 60 mph in 4.9 seconds, while top speed remains limited to 155 mph.
