Audi is introducing two new performance sedans at the LA Auto Show later this month. Both pack the same 4.0-liter twin-turbo V8, producing 605 horsepower and 516 pound-feet of torque (553 on overboost).

The more conventional of the two is the 2016 Audi S8 Plus, which is based on the A8 and emerges as its new performance flagship. 0-60 is quoted at 3.7 seconds, with top speed electronically limited to 155 miles per hour. For all that muscle and luxury, Audi will charge $115,825 (including $925 for destination). Compared to the Mercedes-AMG S63, the new Audi offers more power (but less torque) and quicker acceleration for a much lower price. The Jaguar XJR charges about the same but gives back less muscle and performance.

Joining it is the 2016 Audi RS7 Performance fastback. It packs that same engine and eight-speed automatic transmission with Quattro all-wheel drive. But in the Sportback, 0-60 is quoted at 3.6 seconds, and the top speed is derestricted to 190 mph. For the RS7 Performance, Audi will charge $129,925. That makes it more potent and just as quick, but significantly less expensive than the Porsche Panamera Turbo S.

Both feature other upgrades to the wheels, aero, and interior, and come with carbon-ceramic brakes to keep all that momentum in check. They’ll both reach showrooms next month. But while the RS7 will still be offered in the existing 560-hp spec for $108,900, the S8 Plus has already replaced the existing model on the Audi of America website.
