What People Are Saying Give it to me straight


The 2013 Audi A8 is offered with three different powerplants – a supercharged V6 with start/stop technology, a twin-turbocharged V8 with on-demand cylinder deactivation and a W12.
by KBB (Feb, 2013)
An eight-speed automatic transmission is standard.

The replacement 4.0-liter V-8 is the twin-turbocharged and features cylinder deactivation that allows it to run as a V-4, just like in the A8.

For those other times, when you're grasping toward an apex in a speeding rage, the carbon brakes are fantastic.

Behind them are vented discs sporting six-pot calipers up front and single-piston calipers in the rear.

But here it's making 520 horses and 481 pound-feet of torque.
by Car and Driver (Mar, 2013)


The last S8 was powered by a high-revving, naturally aspirated, 5.2-liter V-10, an engine that seemed somewhat out of place in a luxury sedan.
by Car and Driver (Oct, 2011)
For 2013, the Audi expands the A8 lineup to four trims: a 3.0T V6, 4.0T V8, S8 and W12.
by KBB (Feb, 2013)
The gain is said to be five percent overall on the European cycle, but when cruising on four cylinders at 50 mph the improvement can be up to 10 percent.

The most obvious changes are the standard 20-inch wheels—21s are available—the aluminum mirror caps, and the grille detailing.
by Car and Driver (Oct, 2011)
A bevy of airbags, antilock brakes and an electronic stability system are standard.
by cars.com (Dec, 2011)
Similarly, the eight-speed ZF automatic can be shifted with steering-wheel-mounted paddles, but they become superfluous once you drop the shift lever into sport and the transmission perks up.
by Car and Driver (Mar, 2013)


For 2013, the Audi A8 is available with a multitude of safety, audio and interior enhancements as optional equipment.
by KBB (Feb, 2013)
Microphones in the headliner gather information on sounds in the cabin and the control unit receives additional data from the crankshaft sensor.
by AutoBlog (Nov, 2011)
This is a villainous luxury car, one so wicked that merely hopping behind the wheel should make you a person of interest to Interpol.
