The A8’s direct-injected V8 has 22 additional horsepower (for 372 total), and it is mated to a new eight-speed automatic transmission for better fuel economy. (The outgoing A8L returned 17 mpg overall in our tests.) Standard equipment includes all-wheel drive, adaptive air suspension, pre-collision avoidance system, and a lengthy roster of power amenities.
The A8 can be further outfitted with radar-guided cruise control, rear collision sensor, and lane-change warnings. With these systems, if the driver fails to slow down when approaching an obstacle, the A8 will sound an alarm. If there’s still no response, it will vibrate the steering wheel and begin to apply the brakes.
The 2011 A8 goes on sale around the end of 2010.
