Audi S8 2025: Ultimate Luxury Performance Review

The Audi S8 stands as a benchmark in the ultra-luxury performance sedan segment, combining ferocious power with refined sophistication. Powered by a twin-turbocharged 4.0-liter V8 engine producing 563 horsepower and 590 lb-ft of torque, it accelerates from 0-60 mph in as little as 3.2-3.8 seconds, all while maintaining everyday usability through quattro all-wheel drive and an 8-speed Tiptronic transmission.

Powertrain Excellence

At the heart of the Audi S8 lies its robust powertrain, engineered for both explosive acceleration and efficiency. The 4.0-liter TFSI V8 features direct fuel injection, variable valve timing, and a 48-volt mild-hybrid system that includes cylinder deactivation for improved fuel economy. This setup delivers peak power at 6,000 rpm and torque from as low as 2,050 rpm, ensuring instant response.

Paired with the smooth-shifting 8-speed automatic transmission, power reaches all four wheels via Audi’s legendary quattro system. Manufacturers limit top speed to 155 mph electronically, though independent tests suggest even greater potential.

• Twin-turbo 4.0L V8: 563 hp, 590 lb-ft
• 0-60 mph: 3.8 seconds (official), 3.2 seconds (tested)
• Top speed: 155 mph (governed)
• Transmission: 8-speed Tiptronic
• Drivetrain: Quattro AWD

Dynamic Handling and Suspension Innovations

The S8’s chassis tuning elevates it beyond typical luxury sedans. Standard all-wheel steering enhances maneuverability at low speeds and stability at high speeds. The optional predictive active suspension uses a front camera to scan road imperfections ahead, preemptively adjusting dampers for optimal comfort and control.

Drive select modes—Comfort, Auto, Dynamic, and Individual—allow customization of throttle, steering, suspension, and transmission settings. This adaptability makes the S8 suitable for serene highway cruises or spirited track runs.

Luxurious Interior and Technology

Inside, the S8 pampers with premium materials like Valcona leather, wood inlays, and ambient lighting. The driver’s seat offers 22-way power adjustments, massaging functions, and ventilation. Dual touchscreens dominate the dashboard: a 10.1-inch upper screen for infotainment and a 8.6-inch lower for climate and vehicle controls.

Advanced driver aids include adaptive cruise control, lane-keeping assist, and night vision. The Bang & Olufsen sound system delivers immersive audio, while wireless Apple CarPlay and Android Auto ensure connectivity.
