Here's how much each will cost.
Audi has released details regarding the pricing of its new S8 plus and RS7 performance. The Audi S8 plus debuted earlier this year as a regular S8 on steroids. The super saloon now has 605 hp and 516 lb-ft of torque thanks to its 4.0-liter twin-turbo V8 motor. This extra power launches the super saloon from 0-60 mph in 3.8 seconds and onto 190 mph, if you have the Dynamic package. New wheels and carbon fiber accents are added to the exterior and red contrast stitching and a premium sound system complete the luxurious interior.
Luckily, the S8 plus is now coming to the States and will start at $114,900. Expect the it to go on sale around December 2015. The RS7 performance that debuted this year also gets a power upgrade. The four-door coupe now has 605 hp and 516 lb-ft of torque coming from its 4.0-liter twin-turbo V8. If that much torque is not enough, an overboost function increases it to 553 lb-ft. All of that power launches the family cruiser from 0-60 mph in 3.7 seconds, 0.2 seconds quicker than the already fast as hell standard RS7. A Dynamic package removes the 155 mph speed limit, upping it to, you guessed it, 190 mph. The super saloon gets carbon ceramic brakes and RS sport suspension with Dynamic Ride Control (DRC) to help control its power.
As for looks, the car receives a new front bumper, rear diffuser, black sport exhaust tailpipes, carbon fiber mirror housings, matte titanium trim and 21-inch cast aluminum wheels. Inside, blue carbon twill inlays and blue contrast stitching enhance the quality of the cabin. The best part is that the RS7 performance can get up to 25 mpg. The RS7 performance will cost around $129,000. If you have that sort of cash and need a speedy four-door then expect to see the RS7 performance arrive on US shores around December 2015.
