Audi has released the hot high-performance S8 Plus to rival the top models from Mercedes and BMW.
The new S8 Plus features an upgraded twin-turbo 4.0-litre TFSI V8 engine that has been tuned to 605 horsepower and 516 lb-ft of torque. 553 lb-ft with overboost.
As a result the big saloon accelerates from 0-62mph in 3.8 seconds before hitting an electronically limited top speed of 305 km/h (189.5 mph).
Other updates include a retuned adaptive air suspension, a modified dynamic steering system and carbon ceramic brakes with anthracite-gray calipers embossed with the Audi logo.
There are also carbon fibre intake surrounds, a sports exhaust system and special 21-inch alloy wheels.
Interior boasts comfort sport seats, brushed aluminium trim, piano accents, stainless steel pedals and Arras red contrast stitching and piping.
The S8 Plus is scheduled to go on sale in Germany in November with prices starting at 145,200 euros.
