Core summary
The B10 S5 combines the shape of a sedan with a lifting rear hatch. It is a new generation, not merely another specification of the previous S5 Sportback.
This guide concerns the B10 S5, with the 2026 US model as its performance reference. Audi calls it a Sedan, but the rear glass rises with the luggage hatch. That distinction matters if the car must carry bulky bags as well as look appropriate outside an office.
Cariary sees the S5 as an everyday performance purchase rather than a lap-time statement. Before choosing it, decide whether you want the extra engine character over an A5 and whether the sloping rear body actually fits your passengers and luggage.
History & generations
The B10 changes the context of the S5 name. Older listings may describe a two-door Coupe, a Cabriolet or the previous Sportback. Those cars are not interchangeable with this new liftback. A registration year alone is a poor way to separate generations during a model change.
The photographs show European B10 examples. They illustrate the body, not a promise that every pictured feature or hybrid specification is fitted to a US-market car.
Body, platform & design
The long roof arc ends in a short rear deck, retaining a sedan-like outline despite the hatch. The white car provides paired front and rear views; the blue display car is a separate example. Look beyond wheel style to the shape of the passenger compartment.
Check rear headroom with the front seats set for their usual occupants. Also open the hatch under your garage ceiling: a useful large opening still needs clearance above the car.

Engine & drivetrain
Audi's US figures describe a turbocharged V6 producing 362 hp and quote 4.3 seconds from 0–60 mph. These are manufacturer figures, not a Cariary road test. Quattro and a seven-speed dual-clutch transmission define the basic drivetrain.
Do not apply a European MHEV-plus description automatically to a US car. Ask for the original-market specification. On a test drive, assess parking-speed take-up and stop-start behaviour, not just one hard acceleration run.
Trim differences
An S5 is a powertrain and chassis model, not simply an A5 wearing an S line appearance package. Equally, an S badge does not prove that every assistance, audio or seat option is included. Compare actual equipment lists rather than dealer photographs.
For daily use, seat comfort and parking visibility can matter more than the largest wheel option. Obtain tyre-replacement quotations for the exact wheels fitted before treating an appearance upgrade as a free benefit.
Interior & seating
The screen-focused cockpit should be evaluated with your own phone connected and the seat in a comfortable position. Try the climate, navigation and frequently used menus while stationary. A large display is useful only if ordinary tasks remain easy to find.
Load the bags you routinely carry through the hatch. Check whether their height requires removing the parcel shelf and whether rear-seat passengers still have room after the front seats are adjusted.
Efficiency & range
Build an ownership budget around your route, not the most optimistic figure from a different country's test cycle. Frequent short journeys, winter temperatures and wheel choice can change the result. A mild-hybrid label, where applicable, does not mean plug-in electric commuting.
Compare insurance, servicing and tyres with an A5 as well as with rival performance models. The S5 premium should buy an experience you will actually use.
Safety & equipment
Demonstrate the fitted parking and driver-assistance functions rather than assuming a brochure's full feature list applies. Check the vehicle identification number for open campaigns and ask about calibration after windscreen or accident repairs. Assistance remains a support for the driver, not permission to disengage from traffic.
Strengths
The S5's distinctive proposition is combining a V6 performance drivetrain with practical hatch access and four passenger doors. It can suit an owner who wants one car for commuting, weekends and longer trips without choosing an SUV.
The value of that combination depends on your real use. A liftback is not automatically more useful if the objects you carry are too tall for its roofline.
A useful middle ground between a conventional executive sedan and a more uncompromising performance car. Buy for its daily versatility, while checking market-specific drivetrain and equipment details.
Considerations
Generation and market confusion are the main shopping traps. A cheaper previous-generation Sportback may still be attractive, but should be judged on its own merits rather than presented as the same vehicle. Likewise, a European display car is not evidence of US standard equipment.
On a used example, inspect service documentation and all electronic functions before prioritising cosmetic extras.
Recommended use
Shortlist the S5 when you want discreet performance and more luggage flexibility than a conventional trunk. It is less compelling if most trips involve tight parking, little luggage and no opportunity to enjoy the larger engine.
For regular bulky loads, compare a wagon or upright SUV instead of assuming the liftback solves every packaging problem.
Rivals & related
A BMW M340i is a useful six-cylinder sedan comparison; the difference in luggage opening is worth testing directly. Within Audi, an A5 asks whether the S5's extra performance is necessary. Compare similarly equipped, same-market cars, not a base price against a loaded demonstrator.
FAQ
Is this the old S5 Coupe? No: this page covers the B10 liftback Sedan. Is 4.3 seconds a 0–100 km/h claim? No, it is Audi's US 0–60 mph figure.
Does every photographed detail match the US model? No. European examples illustrate the generation; equipment and electrification must be checked for the original market.

Manufacturer references identify the dated specifications used here. Cariary buying assessments are editorial analysis, not a claimed first-hand road test or a diagnosis of an individual vehicle. Photographs carry individual source and licence credits. Confirm the exact build, market and equipment before purchase; photographs of another trim do not establish your car’s specification.
