Not satisfied with their current offering that already supplies an extra 120 horses to the Audi S8, ABT Sportsline are out with another boost to their kit. Their first kit was released back in May, but this update to the kit further improves the Audi sportscar's output to 675 HP and 619 lb-ft along with a series of additional tweaks to its look. Combined, the improvements drop the 62mph time from a dead stop to 3.6 seconds from the stock 4.1 seconds while also removing the 155mph top speed limiter, which allows for a new maximum speed of 180 mph. The exterior also packs a new punch of its own, lowering the height by 25mm, adding in a new custom muffler system, and a set of optional 20- and 21-inch alloy wheels. Already available, continue after the jump to see what the tuner did to the look and powerplant and reach out directly to ABT if your Audi needs a complete make-over.
