The electric power steering is precise and offers good feedback, making the S5 Sportback agile and confidence-inspiring through corners. The Quattro all-wheel-drive system provides exceptional grip and traction, ensuring optimal power delivery and stability in various road conditions. 

The car feels planted and stable at high speeds, and body roll is well-controlled. Despite its sporty nature, the S5 Sportback manages to absorb most road imperfections reasonably well, making it comfortable enough for daily commuting and long-distance touring. The Audi Drive Select system allows drivers to customize throttle response and steering feel to suit their preferences.

The interior of the 2025 Audi S5 Sportback is a masterclass in driver-focused luxury and advanced technology, meticulously crafted to complement its sporty nature.

The cockpit is designed to immerse the driver, with a low seating position and highly supportive electrically adjustable sport seats that offer 4-way lumbar support. The cabin offers comfortable seating for five occupants, with decent legroom in the rear. However, the sloping roofline might slightly compromise rear headroom for very tall passengers.

 Key features include a 12.3-inch Audi Virtual Cockpit (digital instrument cluster) that offers S-specific performance displays and customizable views.
