For the 2013 model year, the Audi A8 gets a series of new engines and trims, bringing down the model's overall starting price.
The 2013 A8 now has four engine choices instead of two. The new A8 can be equipped with a carryover 500-horsepower, 6.3-liter W12 or two new engine offerings: a twin-turbocharged 4.0-liter V-8 (replacing last year's 4.2-liter V-8) or a supercharged 3.0-liter V-6. A new Audi S8 model is equipped with a 520-hp, twin-turbocharged 4.0-liter V-8. Both 4.0-liter V-8s come equipped with cylinder deactivation, which turns the V-8 into a four-cylinder under certain conditions. All the models are mated to an eight-speed automatic transmission and Audi's Quattro all-wheel-drive system.
