Engage Dynamic mode, and the setup firms up, erasing lean through corners while optional rear-wheel steering enhances agility, making the sedan feel nimbler than its size implies.

Braking is confident with upgraded calipers, and the Quattro system ensures traction in all conditions.

Rear seating offers ample legroom and headroom for adults, with a 12.6-cubic-foot trunk expandable via 40/20/40 folding seats—practical for families or gear-hauling. Visibility is excellent, aided by a commanding driving position that accommodates various body types. Noise insulation keeps the interior serene, even under hard acceleration.

Advanced Technology and Infotainment

Audi’s dual-touchscreen setup dominates the dash: a 10.1-inch upper display for infotainment and an 8.6-inch lower for climate controls. Haptic feedback provides satisfying clicks, easing navigation despite the button-less design. Apple CarPlay, Android Auto, navigation, and a Bang & Olufsen premium audio system (optional in Prestige trim) elevate connectivity.

The Prestige package adds a head-up display, 360-degree cameras, and HD Matrix LED headlights. Driver aids like adaptive cruise, lane-keeping, and night vision (detecting pedestrians/animals) function reliably without intrusion. However, some safety features require higher trims, unlike more generous rivals.
