At first glance, you'll hardly be able to tell a difference between the 2007 Audi A8 and the testing mule you're staring at here. The most obvious differences are the extra-wide fenders flares on the mule. Nevertheless, this is the next iteration of the A8, which will also sport some mechanical upgrades when it debuts in 2009. Audi will be looking to make the A8 lineup a more athletic group of luxury sedans by lowering the car's weight and distributing it better on the Modular Longitudinal Platform it will share with the bulk of Audi's passenger car lineup. We're particularly excited about the possibility of Audi dropping in the 6.0-liter V12 TDI that will first be offered in the Q7 SUV. Inspired by the same engine that propelled Audi's pair of R10 LMP1 racers to victory in the American LeMans Series, this engine produces a beastly 500 hp and 737 ft-lbs. of torque. The V12 will be crazy in the Q7 and Grade-A insane in the lighter A8. You can check out more spy shots of the A8 at the link, but we'll warn you there's not much new to see for now.
Thanks for the tip, Jason!
