Audi S8 4L V8 Twin Turbo Overview
The Audi S8 4L V8 Twin Turbo, introduced in 2013, combines executive luxury with serious performance. Powered by a 4.0 litre twin turbocharged V8 engine producing 563 horsepower and 800 Nm of torque, it delivers rapid acceleration through an 8 speed automatic gearbox and Audi quattro all wheel drive system. With a 0 to 60 mph time as low as 3.2 seconds and an electronically limited top speed of 155 mph, the S8 offers supercar level pace in a refined saloon package.

Advanced Performance Technology
This model features advanced engineering including direct fuel injection and cylinder deactivation to balance power with efficiency. To enhance the Audi S8 Exhaust System, a full DPF delete and custom catback Audi S8 Exhaust upgrade were carried out ahead of a planned Stage 1 pops and bangs remap. Removing the DPF and upgrading the rear exhaust section significantly reduces exhaust backpressure, allowing the engine and turbos to perform more efficiently and respond faster under load.

Luxury, Handling, and Efficiency
Inside, the S8 provides a spacious and luxurious cabin, supported by adaptive air suspension and rear wheel steering for improved agility and comfort. Weighing approximately 2100 kg, it maintains impressive composure while delivering strong performance. Following the Audi S8 Exhaust upgrade, the vehicle benefits from improved exhaust flow, sharper throttle response, and a deeper, more aggressive exhaust tone that enhances the V8 twin turbo character.

Performance Upgrades by DKU Performance
To prepare the vehicle for Stage 1 tuning, a DPF delete and custom back section exhaust system were completed. This Audi S8 Exhaust System upgrade increases sound presence while reducing restriction, ensuring the engine can fully benefit from the upcoming remap. The result is a more responsive and better sounding Audi S8 that delivers a refined yet noticeably more engaging driving experience.
