2003 ABT AS8
In order to get maximum benefit from the skills of his engineers, the technical director of the Abt Sportsline GmbH has chosen the top model for the improvement, the A8. With its V8 supercharged engine and quattro four-wheel drive, this car provides an excellent starting point.
With 335 hp (246 kW), the A8 is already quite powerful, but for a company like Abt Sportsline, with its roots in motorsport, this figure is not enough. After installation of the Abt supercharger kit, the power unit delivers 450 bhp (331 kW) and lets the AS8 reach 174 mph (280 kph). The kit also includes a sensor-operated and water-cooled intercooler as well as exhaust temperature control. Other modifications are made to the air intake, fuel supply and injection systems.
In order to get the power of the Abt AS8 on the road in an effective and safe way, the car has been equipped with ninteen inch sports wheels and ContiSportContact-tyres. They work in tandem with the Abt sports brake system, specially designed for the highest requirements.
Developed in house, the Abt Level-Control (ALC), presents optimal comfort with lowered bodywork. When standing, the car is much lower than the regular production version. While driving, the bodywork is higher to achieve optimal driving dynamics. With a manual selector, the driver also has the possibility of individually adjusting the amount of lowering and adapt it to his or her driving style.
Abt Sportsline is also improved the styling of the A8 with front spoiler edges and a discreet spoiler on the rear of the car. Also at the rear, the Abt exhaust silencer with its four pipes also bears the signature of the company.
