Having learned a thing or two about improving dynamics from the RS4, the S8 features a revised version of the quattro AWD system
with an asymmetrical torque split. Rather than the 50:50 we're accustomed to seeing, the car features a 40:60 split to reduce understeer and create a more neutral rear wheel drive bias. The system can still juggle torque, directing a max of 85 percent to the rear and 65 percent to the front if needed.
Meanwhile, the six-speed Tiptronic automatic gearbox features a shorter final ratio which enables a W12-matching 5.1 seconds for the sprint to 100 km/h. Unsurprisingly, there are no ill effects to top speed, given that it is electronically governed to 250 km/h.
To match the additional power of the motor, the A8's aluminum air suspension has been upgraded as necessary. The car now rides 20 mm lower with
firmer springs and dampers, though the ride height and comfort levels are adjustable through the MMI control system. New rubber bushings and a tweaked steering system aim to further improve body control and overall feel. As for stopping power, conventional discs have been upgraded to 385 mm front and 335 mm rear carbon ceramic brakes for increased performance, lower unsprung weight and reduced maintenance.
As with the past S8, identification on the road will amount to little more than a guessing game. Changes are stealth-oriented and minor, including 'S' trademarks that include brushed metal mirrors, metal trim on the door handles, S8 badges, quad tailpipes and 20-inch wheels inspired by the Le Mans Quattro concept, wrapped in 265/35 ZR 20 tires. The S8 makes its world debut at the Tokyo Motor Show this week, and will be available late 2006 at a price of 97,500 euro (est. $137,500 CAD; $117,000 USD).
