Audi S8 (2023) Review
Premium SUVs may stand higher on the desirability podium than first-class sedans these days, but there is still something innately appealing about a grand saloon that also delivers crushing performance. The 420-kW Audi S8 is one such machine…
We like: Build quality, comfort, “iron-fist-in-velvet-glove performance”

Where does the 2023 Audi S8 fit in?
The current-gen Audi A8 (internal code D5) has been around since 2017. Although it was updated last year, it’s the elder statesman of the traditional Audi/BMW/Mercedes-Benz luxury sedan triumvirate. The demand for cars such as these has shrunk so significantly that Audi no longer offers normal derivatives of the A8 in South Africa; the sole variant available is the more performance-oriented S8 – tested here.
Priced at nearly R2.8 million (before options), the S8 doesn’t really have direct rivals, seeing as BMW doesn’t offer an M-Sport badged 7 Series of similar capability (yet). The Three-pointed Star, in turn, revealed the Mercedes-AMG S63 E Performance late last year, but the Affalterbach-based division’s 590-kW S-Class is another league altogether. It might come to our market one day, but don’t bet on it.
So, where does this leave the Audi S8? Who is going to buy it? Not many people, we think, but that’s more a result of market shifts than an indication that there is anything insufficient about – or wrong with – the product. It will appeal to a small group of people who place a premium on the combination of stonking performance and supreme luxury, and the ability to fly (somewhat) under the radar.
Compare the S8 with those of the BMW i7 xDrive60 M Sport and Mercedes-Benz S500 L AMG Line
How the 2023 Audi S8 fares in terms of…
Design and Packaging
Although the D5-generation Audi A8 is now the oldest of the German Big Three 1st-class sedans, it still looks relatively fresh (with marginally sharper exterior details) by virtue of its recent facelift. That said, it lacks the elegance of the Mercedes-Benz S-Class and the boldness, no, brashness of the BMW 7 Series.
The effect is subtle, but nonetheless noteworthy. At the front end, the base of the S8’s single-frame grille is wider, while chrome trim pieces, which increase in size from bottom to top, adorn the grille itself. The side air intakes are more upright than before, while the headlight design has been tweaked as well.
As before, the Audi S8 sports familiar Audi Sport exterior accoutrements, including a quartet of exhaust ends, distinctive blades around the air intakes, digital Matrix LED headlights, as well as OLED tail lights.
The sporty variant of the Ingolstadt-based firm’s grand saloon still turns heads – largely, we think, because you don’t see it on our roads very often. In all fairness, it’s also a handsome beast, particularly when riding on the stunning Y-spoke “Evo” 21-inch wheels, for which you would pay an extra R16 000.
Inside, you’ll find Audi’s Virtual Cockpit Plus, as well as the latest MMI Navigation Plus system, while a night-vision assistant system is available as an option. The touch-response operating concept remains in place, relying on a pair of displays (10.1- and 8.6 inches in size, respectively) and voice control.
As is the case with virtually all contemporary Audi models, the interior build quality and materials are top-notch – certainly superior to what you’ll find in the more plasticky S-Class. But while the S8’s cabin has most of the latest tech and more than enough digital displays and touchscreens, the compartmentalised structure of the Audi’s fascia is still relatively old-school, compared with those of its newer rivals.
Standard features include all-wheel steering, adaptive cruise control, sumptuous Valcona leather upholstery (with diamond stitching), seat ventilation (with a massage function) and a Bang & Olufsen premium audio system (you can upgrade to an “advanced” version for an extra, oh, R105 000).
If you specify the rear seat package (for an additional R60 000), you’ll get a 3-seat configuration that includes a pair of electrically adjustable outer pews. The latter seats also offer pneumatic 4-way lumbar support, a memory function and crash protection via side airbags. A rear-seat infotainment setup (compromising two 10.1-inch displays) is available; ticking that option will add R33 500 to the price.
Performance and Efficiency
As before, the Audi S8 is powered by a twin-turbo 4.0-litre V8 that serves in a variety of other VW Group models. In this application, the petrol motor churns out 420 kW at 6 000 rpm and 800 Nm from 2 050 to 4 500 rpm. The engine is mated with an 8-speed automatic transmission and, of course, Audi’s quattro all-wheel-drive system, which ensures all that power gets transmitted to the road as swiftly as possible.
And swift is exactly what this near-3-tonne limousine is! If you’re in a hurry to get to your destination, select a sporty drive mode and flatten the accelerator pedal – the S8’s nose will lift (speedboat-style) as the sedan hurls itself towards the horizon. Audi claims its “thunder saloon” can accelerate from 0 to 100 kph in only 3.8 sec, but on our test trip, the S8 bettered that. We recorded a blistering run of 3.63 sec!
While the V8 does emit a lovely roar when it’s required to perform optimally, it never becomes raucous, which is exactly what you would expect (and probably want) from a car such as this. It is a wonderful sensation to experience shattering performance being delivered with such incredible refinement. The 8-speed ‘box is a delight to use; it delivers crisp, fast shifts in response to ‘shift paddle inputs and, with so much torque at its disposal, the S8 effortlessly delivers refinement – and urge – on the daily commute.
Fuel economy? Would prospective buyers even care? For what it’s worth, Audi claims an average figure of 10.5 L/100 km, but you’re more likely to achieve around 13 L/100 km. At least it has a 72-litre fuel tank.
Comfort and Features
To reiterate, the Audi S8 is a comprehensively specified machine – a standard S8 is loaded with so many luxuries that occupant comfort levels are sky-high. So, in a way, the few options that are available simply serve to help buyers individualise their cars. The seats are superb: when you’re ensconced in the supple leather trim and relatively soft padding, you may initially forget about the Audi’s sporting pretensions. When the Audi is made to corner with verve, however, the seats also support you in all the right places.
The S8 is a big car in anyone’s book, but it’s about 20 cm shorter (in overall length and wheelbase) and a little lower than its BMW and Mercedes-Benz rivals. It’s only very slightly narrower, though, so the Audi’s cabin is very roomy and, surprisingly, it has the biggest boot capacity. More importantly, the cabin width is allied with impressive headroom, so there really is plenty of space to relax, wherever you’re seated.
Comfort levels in the rear are excellent (4-zone climate control is standard), there are sunblinds for privacy and, of course, a rear infotainment system is optional. We often criticise the German brands for charging extra for items that should be standard, but in the S8’s case, at least, Audi has found a pleasing blend of features, while retaining the ability to offer “something a little extra” for customers who want it.
The same approach pertains to safety features. The S8’s standard spec includes automated parking (a nice-to-have on a big vehicle), a very high-definition 360-degree camera display, a head-up display and a lane-change assistant with rear cross-traffic alert. If you want Night Vision, that’ll be an extra R45k.
Ride and Handling
Audi has really thrown its best tech at the S8, all of which is standard! You are made aware of this the moment when you open the driver’s door and the car raises its ride height automatically (by 50 mm) to facilitate easier ingress.
Quattro all-wheel drive ensures that the S8 puts its power down as effectively as possible, but moreover, the marque’s sport differential can vary the amount of torque transmitted to each individual rear wheel.
And then there is a frankly mind-boggling Predictive Active Suspension, which uses a camera to scan the road ahead and electro-mechanical actuators to continuously fine-tune the S8’s ride height. Audi says that when Dynamic mode is active, the body roll is cut to about half of that of a car with steel-sprung suspension. The firm also claims the damping actions can be adjusted a staggering 18 times a second!
In the past, big, fast Audis equipped with air suspensions and fitted with big wheels (usually shod with low-profile tyres) often failed to deliver supple ride qualities, but this S8 rides magnificently. In Comfort mode, it wafts along in a manner one would expect of a R3-million limo’. Cabin insulation is admirable. There is an aura of calmness and serenity about the car when driven in this mode, even when it traverses road imperfections at low speeds, which can sometimes catch out air-sprung cars that have big wheels.
When you’re in the mood to drive enthusiastically, the S8 quickly adapts to the situation with a noticeably firmer suspension setup that keeps the body as level as possible. The result is that you can hustle this car with confidence – it has so much grip and great traction out of the corners! It’s never a leary tail-happy type of car, but cool, calculated and shatteringly fast. Driven like this, there is also just enough of that V8 roar to please the driver. As is to be expected, the steering is devoid of feedback, but at least the weighting is pleasant and it’s precise and “fast” (undoubtedly aided by the rear-wheel steering system).
Price and After-Sales Support
The 2023 Audi S8 quattro costs R2 759 000 (before options, May 2023). The price includes a 1-year/unlimited km vehicle warranty as well, as a 5-year/100 000 km maintenance plan.
Verdict
Finding a direct rival for the Audi S8 is no simple task… Mercedes-Benz doesn’t offer a similarly powerful/luxurious S-Class derivative at present, and BMW’s all-electric i7 may be fast and oozing with tech, but it’s not quite as fast as the S8, plus its design is divisive, to say the least. You can have a look at a Porsche Panamera for similar money, of course, but then you’d have to sacrifice some spaciousness.
Ultimately, then, the Audi S8 is a truly niche offering that will appeal to a very particular buyer – one that does not need to drive the latest model on the market and can appreciate the visceral performance that a twin-turbo 4.0-litre V8-engined 1st-class sedan can offer. Those who do opt for Audi’s flagship sedan will undoubtedly have done their homework and know what they want. They won’t be disappointed.
