Design & Presence

The Audi A8 cuts an authoritative silhouette that reads executive rather than ostentatious, with a long bonnet, taut shoulder lines and a wide stance that together signal its 5.19–5.32 m length and near-2 m width. The detailing is typically Audi: restrained chrome, matrix LED lighting and a broad single-frame grille that give presence without shouting. In town the proportions make parking and narrow streets more noticeable, but on the move the A8’s size communicates status and calm. The long-wheelbase option stretches that presence further, offering a limousine-like profile for rear-seat passengers.

Interior & Usability

The cabin is a study in material quality and quiet execution, with soft leathers, real metal or wood trim and impeccably finished switchgear that feel durable and upscale. Controls centre on oversized, crisp screens and a configurable digital instrument cluster, paired with ergonomics that keep major controls within easy reach. Seats are richly upholstered and highly adjustable with available heating, ventilation and massage functions, making long journeys less taxing. Practical touches such as widely opening doors and refined climate control add daily usability for driver and passengers alike.

Space & Everyday Practicality

Space is where the A8 lives up to its limousine ambitions: five seats are standard and the trunk holds about 505 litres, large enough for airport luggage or grocery runs without folding seats. The long-wheelbase variant adds meaningful rear legroom, turning the back seats into a genuine office-on-wheels for those who spend time as a passenger. Curb weights from roughly 2,035 to 2,295 kg explain the solid, planted feel but also mean extra attention to fuel use and parking in tight urban garages. An 82-litre fuel tank helps extend the intervals between fill-ups, which matters on frequent highway trips.

Driving & Handling

The A8 range spans mild-hybrid petrol and diesel V6s, long-wheelbase choices and a high-performance S8, delivering power from around 286 hp up to 571 hp and torque figures as high as 800 Nm. Acceleration numbers underline the difference: mid-spec models reach 0–100 km/h in the mid‑5 second range while the S8 drops into the high 3s, so everyday commuting feels brisk and the S8 is genuinely sports sedan quick. Audi’s quattro all-wheel drive and adaptive air suspension balance comfort with composed handling, smoothing motorway miles while limiting body roll in corners. Heft from the car’s mass keeps the ride secure but means the steering trades razor-sharp feedback for confidence and straight-line stability.

Efficiency, Consumption & Range

Fuel consumption varies predictably: the petrol mild-hybrid sits around 9.3 L/100 km, diesel around 7.0 L/100 km and the S8 nearer 11.5 L/100 km in combined figures — real-world urban figures will be higher. With an 82-litre tank these numbers translate roughly to practical ranges of about 880 km for the petrol, roughly 1,170 km for the diesel and around 710 km for the S8 under mixed driving conditions. For buyers who rack up motorway miles the diesel offers clear efficiency and range benefits, while the petrol and S8 prioritise performance over economy. Consideration of average trip length and fuel costs will influence which engine makes the most sense for everyday use.

Assistance & Infotainment

The A8 is equipped with advanced driver assistance systems that shine on long runs: adaptive cruise with lane keeping, traffic-jam assist and an array of parking aids reduce fatigue and make dense traffic more tolerable. Infotainment combines a high-resolution digital instrument cluster and large central touchscreens with intuitive smartphone integration and available premium sound systems for a refined multimedia experience. Some menus and touch controls reward a short learning curve, after which the system is smooth and responsive for navigation, media and phone tasks. Safety tech and semi-autonomous features are useful in everyday driving, but drivers should be aware of system limits and remain engaged.

Who is it for?

The Audi A8 targets executives, frequent long-distance travellers and anyone seeking a composed, well-equipped flagship that prioritises comfort and technology over outright sportiness. Buyers who value rear-seat space and limousine-like comfort will prefer the long-wheelbase variants, while those wanting dynamic performance will find the S8 compelling despite higher running costs. For corporate fleets, chauffeur services or owners who want a discreet but sophisticated presence, the A8 delivers a convincing package. Choosing between diesel, petrol or the S8 depends on mileage, performance appetite and operating-cost priorities rather than compromise on the core luxury experience.
