The 2013 Audi S8 is no slouch, but German tuning house ABT Sportsline has taken to upping the ante even further. This time, ABT claims to have added more than 100 hp to the luxurious sedan's output.
ABT Sportsline claims to be the world's largest tuner of Volkswagen Group vehicles; we've previously seen the company churn out modified versions of the Audi A1 Sportback and Q3, as well as the Volkswagen Beetle and Touareg. No surprise, then, that ABT wanted to get its hands on the hottest, most luxurious new Audi on the market.
The stock 2013 Audi S8 uses a twin-turbocharged, 4.0-liter V-8 engine rated for 520 hp and 479 lb-ft of torque. That's enough to send the 4354-pound Audi from rest to 62 mph in a claimed 4.2 seconds, and on toward an electronically limited 155 mph.
ABT Sportsline, however, has tweaked the engine programming of the turbocharged Audi to produce 620 hp and 575 lb-ft. That's just a preliminary number, however, and the mad German tuners note that official power outputs could be even higher. In their testing, ABT Sportsline says the so-called AS8 will rocket to 62 mph in four seconds flat, and the tuning firm has increased the top-speed limiter to 180 mph.
In addition to the horsepower upgrades, ABT offers new 20- and 21-inch wheels wrapped in sticky performance tires, and an electronics package called ABT Level Control that keeps the Audi S8's air suspension hunkered down in order to lower the car's center of gravity. Company managing director Hans-Jürgen Abt claims that the modified AS8 is, "The best of both worlds, that is, the best in terms of both comfort and acceleration and agility."
