Audi A8 Review 2024
Audi A8 At A Glance
Insurance Groups are between 20–50
On average it achieves 117% of the official MPG figure
If it’s good enough for many heads of states and royalty, the chances are the Audi A8 is just as good for you. Masses of space for all of its occupants is a given, and it drives with confident ease with a choice of petrol, diesel or hybrid power as well as the potent Audi S8 performance version. Read on for our full Audi A8 review.
The fourth-generation Audi A8 arrived in 2017 and is a luxurious saloon packed with tech that wouldn’t look out of place in a James Bond movie. Its autonomous driving capability and remote parking features still feel futuristic.
Like the BMW 7 Series and its other key rival, the Mercedes S-Class, the Audi A8 is designed to waft VIPs, celebrities and well heeled passengers from A to B in lavish style and comfort.
The interior is beautifully finished, with high-quality wood trims, smooth touchscreen controls and hand-stitched leather trims.
The Audi A8 is enjoyed best as a passenger, with the large rear seats providing a near-silent sanctuary from the outside world.
The leather materials wouldn’t be out of place in an upmarket hotel lounge, while the wide and soft cushioning provides opulent comfort over long distances, especially when fitted with the massaging and heating functions.
As well as delivering more comfort, more interior space and a more rounded ride quality than before, the Audi A8 also has some computerised party pieces up its sleeves. Audi AI traffic jam pilot, for example, allows the car to automatically control throttle and braking responses, while also steering the car in nose-to-tail traffic up to speeds of 37mph.
Autonomous driving isn’t the only fancy bit of next-gen tech. Active suspension independently raises and lowers individual wheels to give an impeccable ride quality over rough road surfaces and potholes, while all-wheel drive provides smooth and responsive handling.
Indeed, despite measuring over five metres in length, the Audi A8 is a very good car to drive and its refined throttle and steering responses make it easy to get the most of its sophisticated running gear.
Initially there were two engines – a 3.0-litre V6 TDI diesel and a 3.0 V6 TFSI petrol. Both use a 48-volt mild hybrid system to improve economy and provide a smooth, near-silent set away. A more powerful V8 diesel and plug-in hybrid joined in 2018, with the latter giving the Lexus LS a serious rival.
The Audi A8L long-wheelbase model is aimed at the chauffeur market and only comes with the 50 TDI 3.0 V6 diesel, while the hybrid and its long-wheelbase version use the 3.0 V6 petrol with electric assistance. In the Audi S8, you get a 571PS twin-turbo 4.0-litre petrol V8 for 0-62mph in a very un-limo-like 3.8 seconds.
The exterior of the Audi A8 might not be as eye-catching as its rivals, even after a 2021 facelift, but the understated design and plush interior give the Audi an upmarket feel that nudges it ever closer to the leader of the limo pack, the Mercedes S-Class.
The autonomous capability also gives an exciting preview of what Audi has in store for the next-generation Audi A3 and A4, with the technology certain to filter down into the car maker’s everyday vehicles over the next few years.

Audi A8 handling and engines
- Engines range from 50 TDI to 4.0 TFSI 571 quattro
- Readers report Real MPG to be between 26–55 mpg
Audi A8 2024: Handling and ride quality
It might be designed for passengers and the size of a small city centre apartment, but the Audi A8 is a surprisingly capable and stress-free car to drive.
The steering and pedals, for example, transmit very little vibration to the driver, while the handling is nimble and accurate. Indeed, just a deft touch is required to make slight adjustments to speed or road position.
At 5172mm long and 1945mm wide, the Audi A8 is a big car. Things grow to van-like proportions when you opt for the long-wheelbase version, with the A8 L stretching out to 5330mm.
As a result, we’d recommend fitting the optional Technology Pack Pro with its four-wheel steering, which gives the Audi A8 a much lighter feel on the road and reduces the turning circle. This makes the car a lot easier to park and turn when space is tight.
While the technology fitted to the Audi A8 generally makes life easier, it can be a hindrance at times. For example, we found the lane departure warning with emergency assist a little too keen to interfere.
The ride quality is much better than on the old Audi A8, with the adaptive air suspension – fitted as standard – smoothing out bumps in the road. Corners can be taken with pace without troubling passengers, while the body is only liable to pitching uncomfortably when you brake or accelerate hard.
From mid-2018, an active suspension system has been available, allowing the car to automatically adjust damping and ride height to improve ride quality over rough roads.
Audi A8 2024: Engines
All of the engines get ‘mild hybrid’ tech, which comprises of a small lithium-ion battery to allow the car to coast along without using the engine. Or you can go for the plug-in TFSI e with its full hybrid system that offers up to 36 miles of electric-only driving.
Given its considerable size and weight, the Audi A8 is reasonably efficient by Audi’s official figures, with the entry-level 286PS 3.0 V6 TDI (badged as 50 TDI under the company’s naming structure) returning an advertised 50.4mpg.
The 340PS 3.0 V6 TFSI petrol (55 TFSI) is the least efficient, returning 37.7mpg under the combined NEDC test. Both versions use an eight-speed automatic gearbox and there are no plans to add a manual.
The 50 TDI is the most-rounded engine in the range, with 600Nm of torque providing mountains of low-gear torque. This means the Audi A8 will complete the 0-62mph dash in less than six seconds, which makes overtaking seldom an issue.
However, despite the executive punch, the engine is smooth and refined, only emitting a low-pitched rumble when pressed hard.
You’d have to feel strongly against diesel to opt for the TFSI engine. It’s not that it’s a bad engine – far from it, as it’s refined and offers good performance when you’re heavy with the throttle.
But the running costs can be crippling. In day-to-day use, we averaged mpg in the mid-20s according to the trip computer. With a bit of hypermiling we were able to reach the NEDC figure but, if you’re economy-minded, why not choose the diesel or the plug-in hybrid?
Audi A8 2024: Safety
The Audi A8 is one of the most complete cars ever when it comes to its list of standard safety kit. Although it’s not been tested by Euro NCAP, the similar Audi A7 has and it recorded a full five-star score.
As well as the expected array of airbags, the Audi A8 comes with adaptive cruise control, active lane assist, speed limiter, swerve assist and turn assist. There’s also autonomous emergency braking, a head-up display, front and rear parking sensors, rear parking camera and traffic sign recognition.
Audi’s Pre-Sense system can detect hazards and prepare the car for what might happen, such as tightening seat belts and priming the brakes for an immediate response. All A8 models now come with Matrix LED headlights as standard.
Audi A8 2024: Towing
The Audi A8 is not the most obvious tow car, but its size, weight and strong engines lend themselves to the task of pulling an unbraked trailer of up to 750kg with ease. Go for a braked trailer and the Audi A8 can tow up to 2300kg.

Audi A8 2024: Practicality
As a passenger experience, the Audi A8 comes extremely close to matching the comfort and refinement of the Mercedes S-Class. The ride is slightly firmer than on its German rival, but the Audi A8 provides exemplary body control.
Indeed, despite weighing in at more than two tonnes, the Audi A8 wafts over rough roads without disturbing those sitting in the rear.
The smart and minimalist dashboard is dominated by a two-tier touchscreen that measures close to 20 inches. This crisp and clear display provides easy access to all of the navigation, media, ventilation and in-car operations.
Even the air vent controls are operated via smart touch controls. Audi’s Virtual Cockpit instrument binnacle is also fitted as standard, which means the driver can customise the display so maps and directions are overlaid on it.
The first-class theme is continued in the back, where an optional rear screen – standard on long-wheelbase models – operates sun blinds, seat adjustments, massage functions and mood lighting.
The controller – situated in the centre armrest – can be removed and operated like a tablet, but will run out of charge if left out of its holder for too long.
The Audi A8 will carry three adults in the back, but it works best as a two-seater due to the slight elevation of the middle seat. The door pockets are deep and wide, which means passengers can store drinks, a laptop or the phone in them.
Head and legroom is also plentiful, while the long-wheelbase version provides the sort of interior space you’d expect from the first class seat of a transatlantic aircraft.
An optional two-piece panoramic glass sunroof brings more light into the interior, while optional tablet screens can be added to the headrests to allow passengers to watch digital TV or simply follow the vehicle’s route via the navigation.
All versions get a 505-litre boot, which will easily carry three or four large suitcases.
Audi A8 2024: Quality and finish
Audi has always built its cars to an elevated standard, and this generation of Audi A8 takes it a whole new level.
It’s easily on a par with the best from BMW and Mercedes, and there’s even a comparison to made with the Audi’s cousins from Bentley – it’s that good.
Every surface has a feeling of class, and every button, switch and lever (the few physical ones there are) all work with a perfectly damped precision.
It all adds up to an overall impression of a car built by thoughtful, dedicated German precision engineers and craftspeople – which is exactly what happens in the factory.
Audi A8 2024: Infotainment
The infotainment is one of the big attractions of the Audi A8’s cabin, and by big we also mean the size of the screens.
There are twin displays for the ventilation and other in-car functions, with the 8.6-inch one for the air-con and the larger 10.1-inch monitor for almost everything else.
The clear graphics, easy-to-fathom menus and quick response of these screens make them super simple to use. The only minor gripes are that the icons could be a bit bigger and the screens clearer to see in bright sunlight.
As you’d expect of a car at this end of the market, there’s built-in sat-nav, wireless phone charging, Apple CarPlay and Android Auto connectivity, as well as voice commands.
The optional Technology Pack adds a Bang & Olufsen 3D stereo system to the already excellent in-car listening experience.
Audi A8 value for money
Audi A8 2024: Prices
The cheapest, if that’s the right word, Audi A8 costs from £76,225 for the diesel-powered standard saloon model. The petrol adds £1625 to that price, and this is for the Sport trim.
Moving up to S line spec requires a further spend of £4250, while the Black Edition ups that by an extra £2300.
An Audi A8L long wheelbase costs from £80,225, while the hybrid versions start at £88,825 for the standard model and £92,825 for the longer version.
Fancy the high-performance Audi S8? Then rummage down the back of the sofa for the requisite £105,500 starting money.
Audi A8 2024: Running Costs
There’s no low-cost way to run an Audi A8, but the standard 50 TDI offers 40.4mpg combined economy coupled to carbon dioxide emissions as low as 184g/km.
Choose the hybrid model and you get up to 148.7mpg and 42g/km allied to as much as 36 miles of EV driving, although these cost savings are set against this model’s higher initial price.
If you’d rather just have a straightforward petrol version, the 55 TFSI gives 31.0mpg and 204g/km of CO2 output.
There is some respite from the high running costs, as the hybrid has a first-year road tax cost of £10. In contrast, the Audi S8 faces a far heftier bill of £2605.
When it comes to insurance, the least costly are the 50 TDI and 55 TFSI standard models that sit in Group 44. From there, everything is more expensive and the top Audi A8 models are in the highest Group 50 bracket.

- December 2021: Updated Audi A8 priced from £74,985
October 2017
Audi A8 announced
Priced from £69,100 OTR, and due with first UK customers in early 2018, the fourth generation A8 comes in 5.17-metre ‘standard’ form or as the A8 L, which has a 13 centimetre longer wheelbase.
Compared with its predecessor the new A8 has grown substantially in length in both body styles. The interior design dispenses with the familiar rotary pushbutton and touchpad of the previous generation car. At its centre is a 10.1-inch touchscreen display which, when off, blends almost invisibly into the high-gloss black surround thanks to its black-panel look.
The user interface appears as soon as the car is opened. The Infotainment system is controllable via the large display, and a second touchscreen on the centre tunnel console gives access to the air conditioning and comfort functions and enables text inputs.
Information on destinations and media is either available on board or is delivered from the cloud at ultra-fast LTE speed. The navigation system has also evolved in line with the car which houses it – it is able to learn from the route just driven, providing the driver with intelligent search suggestions, and also incorporates highly detailed 3D models of major European cities.
The UK standard equipment list includes everything from the fully digital Audi Virtual Cockpit, the high definition colour head-up display and internet-based Audi Connect services to MMI Navigation Plus and Audi Phonebox wireless smartphone charging.
Standard LED headlights with high beam assist provide suitably precisely defined and far-reaching illumination and are paired with a rear LED light strip. The list of onboard driver aids also includes adaptive cruise assist with Stop&Go, front and rear parking sensors supplemented by a rear camera, lane departure warning with emergency assist and the Audi Pre-sense collision avoidance and mitigation system giving robust occupant protection.
Rear passengers can also control an array of functions such as ambient lighting, the optional HD Matrix reading lights and seat massage, and can make private phone calls via a separate operating unit. The rear seat remote control, with its smartphone-size OLED display, is a removable unit housed in the centre armrest and is optional for the A8 and standard for the A8 L.
The new A8 makes its debut with two V6 turbo engines: a 3.0 TDI and a 3.0 TFSI. The diesel develops 286PS, and the petrol version 340PS. An eight-cylinder TDI – a 4.0-litre with 435PS – will follow slightly later, as will the exclusive top engine version, the W12 with a displacement of 6.0 litres.
All four engines operate in conjunction with a belt alternator starter (BAS), which is the nerve centre of the 48-volt electrical system. This mild hybrid technology (MHEV, mild hybrid electric vehicle) enables the car to coast with the engine switched off, and to restart smoothly. It also has an extended start/stop function and an energy recovery output of up to 12 kW. The combined effect of these measures is to bring down the fuel consumption of the already efficient engines even further – by as much as 0.7 litres for every 62 miles covered in real world driving conditions.
The A8 L e-tron quattro with its powerful plug-in hybrid drivetrain will follow at a later date: Its 3.0 TFSI engine and powerful electric motor achieve 449PS of system power and 700 Nm (516.3 lb-ft) of system torque. The lithium-ion battery stores enough power for about 31 miles of electric driving. Fast charging will be possible via public or domestic charge points and wall boxes, or in the latter case via induction-based Audi Wireless Charging, which uses a pad in the garage floor to transfer power inductively to a receiver coil in the car with a power output of 3.6 kW.
July 2019
Audi S8 announced
New S8 combines the rarefied comfort and refinement of the flagship Audi A8 saloon with a bi-turbo V8 petrol engine channelling an impressive 571PS and 800Nm of torque to the road via predictive active suspension, dynamic-all-wheel steering and quattro drive supplemented by a rear sport differential. These advanced systems ensure the plentiful power is as gainfully employed as possible during more challenging driving, and the latest cylinder-on-demand and mild hybrid drivetrain technologies also manage it responsibly when the car is in relaxed, trans-continental cruising mode.
As a V8 engine with mild hybrid technology, the high-performance unit in the Audi S8 offers not only maximum smoothness, but with an output of 571PS, 800 Nm of torque and two turbochargers also the certainty that ample power is available for any situation.
Iron-lined cylinder barrels in the aluminium crankcase reduce friction for exceptionally smooth running, and for moments when power takes precedence automatically actuated flaps in the exhaust system accentuate the already impressive V8 sound. For the ultimate in comfort, sound intrusion that is less desirable is eliminated by active noise cancellation integrated into the sound system.
The mild hybrid system (MHEV) works continuously to reduce fuel consumption. Its 48-volt belt alternator starter and the additional lithium-ion battery enable coasting with the engine switched off, fast restart and an extended start-stop range. Fuel savings of up to 0.8 litres per 100 kilometres are possible in everyday driving. The cylinder on demand system, which deactivates individual cylinders in low-load operating situations, also helps to moderate fuel consumption wherever possible.
The unique combination of innovative suspension components enables the S8 to consummately fulfil the role of luxury limousine while also approaching corners with the poise of a sports car. The high-tech predictive active suspension, a standard feature that works in conjunction with the adaptive air suspension, helps the performance flagship to perform its dual role - it can lift or push down each wheel separately via electromechanical actuators, making it possible to actively control the trim of the body in any driving situation for the first time, thereby greatly reducing pitch or roll during acceleration or braking. The front camera, which detects larger road surface irregularities, enables this to be done predictively.
The Audi drive select system – another standard feature – also helps to further enhance the impressive adaptability of the S8. It offers a choice of five operating modes, including a new “Comfort +” profile which makes cornering more comfortable by tilting the body into bends by as much as 3 degrees to reduce the lateral acceleration acting on the occupants.
In “dynamic” mode the S8 turns in tautly. The maximum roll angle during fast cornering is roughly 2.5 degrees compared with around 5 degrees with the standard suspension. The situational distribution of roll moments enables self-steering that is neutral or minimally inclined towards oversteer. The active suspension enables another new function. The body is quickly raised by as much as 50 mm when the door handle is actuated for an even more comfortable entry and exit.
Another system designed to make the S8 feel lighter on its feet is the standard dynamic-all-wheel steering. It allows the independent adjustment of the steering angles at the front and rear axles, thereby facilitating quick and direct steering response and a tight turning circle at low and medium speeds but also supreme stability on the motorway. The factory fitted sport differential actively transfers torque between the rear wheels during fast cornering. When turning into or accelerating in a bend, most is directed to the outside wheel to literally push the car into the corner and eradicate any hint of understeer. In the case of oversteer, the differential transfers the drive torque to the inside wheel to stabilise the S8. The interplay between all these standard systems is unique in the S8’s class and ensures composed and sporty handling in all situations.
Customers keen to reap maximum reward from the engine and advanced chassis technology on a regular basis can also choose high-performance carbon-fibre ceramic brake discs with a diameter of 420 millimetres at the front axle and 370 millimetres at the rear from the option list. The ceramic brakes are internally ventilated, low-wearing and including the callipers are 9.6 kilograms lighter than cast iron discs. Each of the front callipers has ten pistons.
Bold interior and exterior design elements finely hone the character of the new S8. Details in the front bumper, side sills and the exterior mirror housings as well as the two S-specific twin exhaust tailpipes subtly convey the car’s standing in the model series. Inside a new upper inlay – available exclusively in the Audi S8 – is made of Carbon Vector with a special 3D depth effect. Directly below that is an inlay of dark, brushed matt aluminium. Matrix LED headlights provide exceptional illumination and depth of field as standard, with an upgrade to HD matrix LED headlights with Audi laser light and OLED rear lights available on request.
Every detail of the new Audi S8 reflects its special capabilities. One particular highlight are the standard sport seats, which feature wide ranging power adjustment, pneumatically adjustable side bolsters and separate three-stage heating for each seat. In addition to this, ventilation and massage functions are available. Customers can choose between the top leather grades Valcona and Unikat. The rear seats also offer numerous features for outstanding comfort and provide for a first-class atmosphere in the Audi S8.
The 38 driver assistance systems that Audi provides for the new S8 are divided into the City and Tour packages. The latter is standard for all A8 models in the UK. It includes Adaptive cruise assist – a stand-out feature that combines the functions of adaptive cruise control, traffic jam assist and lane tracking. In combination with predictive efficiency assist, it brakes and accelerates the Audi S8 in anticipation of the conditions ahead. In the City assist package, Audi pre sense side joins the systems pre sense front and pre sense rear to create Audi pre sense 360°. If the system detects an impending side impact, it can operate together with the predictive active suspension to instantly raise the body by as much as 80 millimetres. This brings the sill into a better position to absorb the impact energy, mitigating the potential consequences of the accident for the occupants.
The brain behind the driver assistance systems in the new S8 is a high-performance processing unit, the central driver assistance controller (zFAS). It continuously computes a differentiated model of the vehicle’s surroundings based on the data provided by the sensors. Fully equipped, there are five radar sensors, six cameras, twelve ultrasound sensors and a laser scanner on board.
The new Audi S8 offers an appropriately sophisticated infotainment interface with new digital services and state-of-the-art connectivity. The fully digital MMI touch response operating concept enables the driver to control nearly all functions via two large touch screen displays with haptic feedback. The driver can also use natural speech control, which offers virtually unlimited freedom when formulating questions and commands. The answers are provided either from information stored on board or from the cloud. Alexa, Amazon’s cloud-based voice assistant, is also available as an option.
All driving-relevant displays appear in the Audi virtual cockpit, which can be switched between two views. While the tachometer and speedometer are displayed as large dial-type gauges in driving mode, the map is the centre of attention in infotainment mode. Both views have S-specific red graphics. A special S-performance layout for the Audi virtual cockpit where the central focus is the tachometer, displayed as a square graph, and the output and torque are shown as percentages can also be selected in the MMI. The head-up display can display important information on the windscreen.
MMI navigation plus serves as the infotainment and media centre in the new S8. Besides the integration of the Amazon Alexa voice service, the extensive Audi connect range includes a wide variety of car-to-X services that draw on the swarm intelligence of the Audi fleet, including online traffic sign information, hazard alerts and on‑street parking search functionality. The myAudi app connects the car to the customer’s smartphone so that they can easily send destinations to the car from their home computer.

Audi A8 L TFSI E plug-in hybrid launched
Capable of covering up to 28.6 miles under electric power, the plug-in hybrid Audi A8 has 449PS and 700Nm of torque.
The A8 L 60 TFSI e quattro, which measures 5.30 metres with its extended wheelbase, will be available to order in the UK later this year, with standard wheelbase models joining the range a few weeks later. First deliveries for both variants will commence soon after in early 2020. They join the Audi A7 Sportback 55 TFSI e quattro, Q5 50 TFSI e quattro and Q5 55 TFSI e quattro SUVs which have already been available on the market since September.
A 3.0-litre TFSI generates propulsion in the A8 L 60 TFSI e quattro. The turbocharged V6 direct-injection engine with a petrol particulate filter delivers an output of 340 PS and 500Nm of torque. An electric motor with peak output of 100kW and peak torque of 350Nm serves as the electric drive, integrated with the clutch in the eight-speed tiptronic gearbox. Power is transmitted to all four wheels via Quattro all-wheel drive.
The Audi A8 L 60 TFSI e quattro delivers a system power of 449PS and 700Nm of torque. This high system torque is already available at 1,250 rpm, which is just above idle speed. When both motors work together in boost mode, the A8 accelerates to 62mph in 4.9 seconds and reaches an electronically governed top speed of 155mph.
The plug-in hybrid A8 starts in “EV” mode, where it drives on purely electric power. The combustion engine is engaged only when the driver depresses the accelerator pedal beyond a specific resistance. The pressure point is variable and based on the power from the electric drive that is currently available.
“Hybrid” mode offers two operating modes: “Auto” and “Hold”. In “Auto” mode, the predictive operating strategy is activated automatically when route guidance is started in the MMI navigation plus (standard equipment). In addition, the battery charge is spread intelligently and optimally along the route, with large electric portions in the city and in stop-and-go traffic. Generally speaking, the predictive operating strategy endeavours to drive as far as possible on electric power and to use the available battery charge completely by the time the destination is reached.
“Hold” mode pursues a different strategy: Here, the available charge state of the battery is kept at the current level with just minimal fluctuations by means of recuperation and by shifting the load point, i.e. with targeted adjustments to the management of the 3.0 TFSI.
Following a long-distance journey that is driven the conventional way, for example, this allows the subsequent urban drive to be covered on purely electric power, i.e. without emissions and in near-silence.
