Great driving report here with the Audi A8L W12 quattro. Enjoy!
Another aspect of the Google-equipped A8 is the addition of mobile WLAN hotspot connectivity. Audi of America is still working out final details with a service provider but our German-market A8L was already connected. After locating the network password in the MMI system, we easily connected with an Apple iPad and effortlessly surfed and checked our email at 3G speeds while our driving partner surfed the Autobahn at three-digit speeds.
Pushing this rolling office or lounge is Audi’s most magnificent engine, the W12. Shared in twin-turbo form with Bentley’s Continental models, this twelve-cylinder engine is unique in the industry for its four banks of three cylinders arranged in a “W” configuration. This time around the W12 has grown in displacement from 6.0 to 6.3 liters, and FSI direct injection has also been added. As a result, horsepower has jumped to 500 (up 50 hp); torque has also risen to 442 lb-ft (up 33 lb-ft) as a result of the added displacement and new injection. At the same time, the new 6.3-liter W12 returns a respectable consumption figure of around 19 mpg on the European cycle (EPA figures are still pending) thanks to improved efficiencies such as lowered frictional loss in the crank and energy recuperation systems.
Another big factor in the A8L W12s improved efficiency is the gargantuan engine’s pairing to Audi’s latest eight-speed Tiptronic automatic transmission, sourced from ZF. Shifts are quicker and smoother than the old six-speed, improving both dynamics, while the two additional gears both serve overdrive functions for greater efficiency.
