The big man on Audi’s campus is the long, luxurious 12-cylinder version of the new A8 sedan, the Audi A8 L W12 (www.audiusa.com). No other automobile offers so much performance, luxury, and refinement in such an understated package. Priced from $133,500, the new W12 is for those who want it all but prefer flying under the radar and keeping the delights of Audi ownership to themselves. The butter-smooth W-12 engine is an Audi hallmark, delivering 500 hp and 463 ft lbs of torque. The 8-speed automatic transmission effortlessly shoots the aluminum sedan from zero to 60 mph in 4.4 seconds—that is M5 territory. The spacious and sophisticated interior, the industry’s most advanced user interfaces and connectivity, and the available Bang & Olufsen surround-sound system make riding in the cavernous backseat nearly as gratifying as driving the W12.
