Previously, the S8 was equipped with a turbocharged 4.0-liter 520-horsepower V8 engine. When the S8 Plus was introduced for the 2016 model year, Audi simultaneously dropped the less powerful engine. Every S8 is now an S8 Plus, with 605 horsepower. For comparison purposes, the base A8 L delivers 333 horsepower.

The S8 Plus features a 4.0-liter twin-turbocharged and intercooled, dual-overhead-cam, direct-injection, 32-valve V8. Torque is abundant with 517 pound-feet available, at just 1,750 rpm. Audi’s overboost function produces an even greater 553 pound-feet of torque for brief periods.
