ABT Power Upgrade | D5 S8 4.0T

ABT power modules give you the ability to add more power to your vehicle safely in a completely reversable manner. This power module is tuned by ABT specifically for your 2019+ Audi S8 4.0T.

Power Level

• Raises horsepower from 563 HP to 690 HP
• Raises torque from 590 LB-FT to 649 LB-FT

Quality at the Manufacturer Level

• Developed on 93 octane 
• 91 octane fuel may also be used, but power output will be less
• No extra fuel consumption
• German DOT (TUV) approved
• Extensively tested on dyno and public roads
• Based on several decades of motorsports experience (Audi factory race team in Formula E and DTM Championship) and performance tuning for street cars

Active Engine Protection

• Performance increase is only released in the optimum range of engine temperature, air temperature and height above sea level

Hardware Protection

• Separate ABT Engine Control Unit (AEC)
• Individually developed for every specific Audi and VW engine
• Non-destructive installation (includes separate wiring harness and stainless steel support brackets)

3D Optimization

• The connection between the AEC and the main engine is ensured through four analog channels, respectively two digital and two analog ones, that correct the data of the sensors (such as pressure, temperature or the positions of the actuators)
• Contrary to most competitors, the AEC works in a three-dimensional way through an engine map combining engine load and rpm.

Fitment/Application

• 2019+ Audi S8 4.0T (4N)
