Audi A8 (2010 – 2017) At A Glance
Superb refinement. Good to drive with nimble handling. 3.0 TDI offers remarkable economy for such a large car. Stylish interior.
Some safety systems were only optional when the car was new. Apart from the dominant grille, styling may be too understated for some.
The Audi A8 luxury saloon has, for many years, been built with an aluminium body to save weight. This design allowed the 2010 version to deliver a svelte ride coupled with amazingly agile handling for such a large car. Only the Jaguar XJ could match the Audi on this front, although the BMW 7 Series and another German offering, the Mercedes S-Class, were clear rivals for refinement and comfort. Read on for our full Audi A8 review.
The third-generation Audi A8 arrived in 2010 as an understated and extremely classy car. There was nothing about its styling an onlooker had to get used to, other than the striking front grille perhaps. It looks exactly like a big, luxurious limousine should.
For interior comfort, there are few better used cars on the road and its amazing refinement, sheer quality and useful on-board technology made it the perfect flagship to the Audi range at the time.
Whether you’re behind the wheel, or lucky enough to be sitting in the back, the Audi A8 is a delightful car to be in.
Its forte is long-distance cruising, which it manages in effortless and cosseting style, helped by an advanced adaptive air-suspension system and a superb range of powerful, yet smooth, engines.
The pick is actually the smallest unit, the V6 3.0 TDI quattro – a powerplant perfectly suited to the Audi A8.
That aluminium body ensures weight is kept to a minimum, which has huge benefits for both handling and efficiency.
The 3.0 TDI is capable of impressive fuel economy, with some versions delivering a claimed 50mpg. The Audi A8 also handles very well, with an agility and composure in corners that belies its size.
Other cars in this class from this era may look more distinctive from the outside, but few can quite match the all-round abilities of the Audi A8.
Even as a used car, it remains effortlessly stylish and helps create the crucial feelgood factor that means every journey is a pleasure.

Audi A8 (2010 – 2017) handling and engines
- Engines range from 2.0 TFSI Hybrid to W12 6.3 L
- Readers report Real MPG to be between 21–48 mpg
Audi A8 (2010 – 2017): Handling and ride quality
Thanks to its incredibly lightweight aluminium body, this Audi A8 is a genuinely great car to drive, and one that handles more like a sporty hatchback.
It’s nimble in corners and deals with quick changes of direction superbly well, so that tackling tight bends is not only enjoyable, but doesn’t result in dizzy passengers.
This ability in corners isn’t to the detriment of the ride quality, and the Audi A8 is superbly cosseting. This is mainly down to the excellent Audi Drive Select system, which comes as standard.
It allows the driver to fine-tune the steering weight, throttle response, gearshift points and air-suspension settings across three pre-set levels – comfort, automatic and dynamic.
There’s a noticeable difference between the three, but the automatic setting is so capable, it tends to be most drivers’ default choice.
One small criticism regards the steering, which often feels quite artificial and over-assisted, although it’s still very responsive to inputs and feels well-weighted at higher speeds.
Even at unrestricted Autobahn pace, the Audi A8 is amazingly stable and reassuring, helped by double-glazed glass which means the cabin is near-silent.
The Audi A8 is packed with technology, but one of its smartest features allows the sat-nav and automatic gearbox to ‘talk’ to each other.
Using the digital road maps, it can factor corners or hills into the gearshifts, so avoids unnnecessary, fuel-sapping gear changes, making journeys not only more efficient, but smoother too.
Audi A8 (2010 – 2017): Engines
The Audi A8 is available with a good range of very powerful, but relatively efficient, engines.
It’s the 3.0 TDI that is the most popular, but although it’s the smallest engine, it’s certainly not the poor relation in the line-up.
If anything, its refined and smooth nature suits the Audi A8 perfectly, and it makes the most sense in terms of running costs.
The 3.0 TDI is available with the quattro four-wheel-drive system and has plenty of power and an impressive 550Nm of torque. This means it gains speed effortlessly, making it a relaxed long-distance cruiser.
It may not have the immediate pace of the more powerful engines, but that’s rarely a problem in a luxury car where comfort is the priority. Best of all, it can average close to 50mpg in some versions.
For more performance, there’s the 4.2 TDI, which is a superb engine with thunderous pulling power. It provides instant acceleration from low down and feels incredibly muscular, yet still returns around 37mpg, which is amazing given the performance on offer.
The standard gearbox on all Audi A8s is an eight-speed automatic that delivers smooth but lightning fast shifts, for the ultimate in effortless, quick progress.
If you’re feeling particularly enthusiastic, there are also steering-wheel mounted paddle shifters, so you can change gears yourself.
Audi A8 (2010 – 2017): Safety
Thanks to its flagship status, the Audi A8 has some safety tech that was rare at the time of its launch.
Alongside the expected range of airbags, ESP, ABS and Isofix child seat mounts, all versions came with Audi’s Pre-Sense system.
Pre-Sense detects the threat of a collision and prepares the car by closing windows and tightening seat belts. It also provides full braking power as soon as the driver touches the brake pedal.
Audi offered the option of upgrading the Pre-Sense system with adaptive cruise control, side assist and automatic emergency braking, which are worth looking out for on any used car you may be considering.
Audi A8 (2010 – 2017): Towing
Using an Audi A8 as a tow car might seem odd to many, but it can pull a braked trailer of up to 2200kg.
Opt for an unbraked trailer and this luxury saloon will happily tow up to 750kg.

Audi A8 (2010 – 2017) interior
- Boot space is 335–520 litres
| Dimensions | |
|---|---|
| Length | 5135–5267 mm |
| Width | 1949–2111 mm |
| Height | 1458–1471 mm |
| Wheelbase | 2992–3122 mm |
Audi A8 (2010 – 2017): Practicality
Longer and wider than its predecessor, this Audi A8 has huge amounts of passenger space – and the best place to appreciate this is in the back.
There’s an immense amount of legroom, helped by the fact that the car is more than five metres long, while the standard leather seats are supple yet supportive, helping long journeys to fly by. There’s even a long-wheelbase version for even more space.
As an optional extra, you could specify electrically adjustable rear seats, but the real benefit of these were that they added heating, ventilation and a massage function.
The same features were also available on the front seats, and the five-program massage system is genuinely relaxing and not – as with some other systems – an annoying intrusion.
In the front, the cabin design is stylish and understated, especially when compared to the Jaguar XJ. But it’s the attention to detail that really impresses, such as the neat gear lever – which is based on the design of the throttle on a high-performance speed boat – or the lovely analogue clock in the centre of the dash.
All the main controls and buttons are perfectly placed for convenience, and there’s a feeling of true luxury about the finish, with everything swathed in supple leather.
Both the front seats and steering column are electrically adjustable, so finding the perfect driving position is straightforward.
The boot, meanwhile, is a good size and with 510 litres of luggage room, has a similar capacity as the contemporary BMW 7 Series (although a Mercedes S-Class boot is larger).
You can easily fit in four golf bags, plus top models come with an electrically opening and closing bootlid as standard.
Audi A8 (2010 – 2017): Quality and finish
The sheer luxury of the Audi A8 is a joy to behold and the quality is everything you’d expect of a car of this type, with only the best materials used throughout and an impeccable finish.
There are some special features that really stand out. For example, when the Audi A8 knows you’re driving abroad – thanks to the sat-nav data – it automatically changes the headlights for driving on the right, plus even alters the clock for you.
Audi A8 (2010 – 2017): Infotainment
The interior of the Audi A8 isn’t littered with switches, and follows a minimalist style.
The likes of the stereo, Bluetooth and satellite navigation are controlled via what Audi calls its MMI system (or Multi Media Interface).
This features a dial (situated in front of the gear lever) for scrolling through the various functions, and a large colour screen that neatly slides out of the dash top.
It’s very intuitive to use and although the sheer number of functions can seem daunting at first, it only takes a short time to familiarise yourself with it.
One of the neatest features is a clever touchpad that allows you to actually write out letters and numbers with your finger, which the sat-nav will recognise.
This means you can spell out your destination without taking your eyes off the road.
Audi A8 (2010 – 2017) value for money
Audi A8 (2010 – 2017): Prices
The vast majority of Audi A8s of this generation on sale come with the 3.0 V6 TDI turbodiesel engine, and it’s the one we’d recommend.
A 12-year-old example with 80,000 miles can be yours from £11,000 in very good condition, and the same amount will bag you a 3.0 V6 TFSI petrol if you can find one for sale.
The 4.2 V8 petrol starts at a higher level, with prices from £12,000, while the rare and exotic W12-powered model will set you back from £19,000.
A seven-year-old Audi A8 will cost around £17,000 for a 3.0 V6 TDI.
Audi A8 (2010 – 2017): Running Costs
If you happen to own a money tree, the Audi A8 W12 is an incredible car to drive, sharing its engine with various Bentleys.
However, most of us will baulk at its 25.7mpg claimed average fuel economy, which is closer to 20mpg in real life.
Even the 4.0 TFSI V8 petrol only offers a claimed 30.1mpg, which is around 25mpg in daily use. If you must go down the petrol route, it’s best to look at the 3.0 V6 TFSI, with its 32.1mpg average economy.
Another petrol option is the 2.0 TFSI Hybrid model with its combined 44.8mpg. It's a rare car to find, and is not especially quick to drive, but it offers economy more akin to a diesel and entry to low emissions zones, mixed with 147g/km carbon dioxide emissions.
Most Audi A8 buyers will opt for the 3.0 V6 turbodiesel thanks to its claimed 49.6mpg, which is achievable on longer runs at a steady pace. The 4.2 TDI V8 delivers a claimed best of 39.2mpg and generally offers consumption in the mid-30s.
If you’re dead set on the W12, reckon on paying £675 each year for road tax, which compares unfavourably to the £200 a 3.0 V6 TDI model will cost you.
That V6 model will also cost less to service, although it’s still not cheap due to requiring high-quality tyres and oil.
Insurance for the less powerful Audi A8 models is not too painful, as they sit in groups 40 to 42. However, the V8 TDI and W12 models are in group 50.

All-new Audi A8 opened for orders
For first deliveries in spring 2010 at OTR prices from £54,760 to £66,240. Highlights include all-LED headlights, new touch screen Multi Media Interface (MMI) incorporating new ‘anticipatory’ satellite navigation with night vision, Audi drive select adaptive dynamics system with optional sports differential. Three enhanced FSI and TDI engines with more power and torque and economy improvements of up to 22 per cent, mated to new eight-speed tiptronic automatic transmission and latest generation quattro all-wheel-drive with asymmetric torque distribution.
All 2010 A8 models feature energy recuperation technology; 3.0 TDI versions also include engine start-stop function. The 3.0-litre V6 TDI with 250PS and 550Nm of torque (up from 233PS and 450Nm), the 4.2-litre V8 TDI with 350PS and 800Nm (up from 326PS and 650Nm) and the 4.2-litre V8 FSI with 372PS and 445Nm (up from 350PS and 440Nm).
The upgraded 4.2-litre FSI benefits from a 13 per cent improvement in fuel economy, taking its combined figure to 29.7mpg and dropping CO2 output to 219g/km. The equivalent V8 TDI gets a 19 per cent boost to 37.2mpg with CO2 emissions down to 199g/km, while the 3.0-litre TDI moves to the top of the luxury saloon class in economy terms with a 22 per cent economy hike to 42.8mpg with CO2 of 174g/km.
During 2010, an even more economy and emissions-focused version of the 3.0-litre TDI unit will be added. Driving the front wheels only, it will combine a 204PS power peak with 47.1mpg economy on the combined cycle and CO2 emissions of just 159g/km.

March 2010
Audi presented an A8 hybrid as a technology concept at the Geneva Motor Show. Its two engines – a 2.0 TFSI and an electric power unit – develop a combined total of 245PS and deliver 480 Nm (354.03 lb-ft) of torque, enabling them to provide the confident driving performance of a large six-cylinder engine. And combined with the advantages of electric power, the consistent downsizing also pays substantial benefits in fuel economy – up to 45.6mpg is possible, corresponding to a CO2 value of 144 grams per km.
The Audi A8 hybrid utilizes a parallel hybrid system – a highly efficient principle that avoids any unnecessary friction and power losses. Interposed between the four-cylinder petrol engine, which delivers 211PS, and the eight-speed tiptronic is a powerful electric motor. It develops 45PS of power and a very ample 211 Nm (155.63 lb-ft) of torque. The two power units together develop a system power of 180 kW and 480 Nm (354.03 lb-ft). This enables the Audi A8 hybrid to accelerate in 7.6 seconds from zero to 62mph and to achieve a top speed of 146mph.
The A8 concept car is a full hybrid. This means that it can be propelled by either the gasoline engine or the electric motor alone – or by the combined power of both. During coasting or braking, the electric motor acts as a generator that converts kinetic into electric energy and recharges the battery. The hybrid drive can propel the car on electric power alone at up to 40mph with a range of over two kilometers – enough for urban stop-and-go traffic.

All-new W12 FSI engine and 130mm of extra length incorporated at the rear enable flagship Audi saloon to set even higher luxury standards. Long wheelbase versions of Audi luxury saloon open for order in late July 2010 for first deliveries in December 2010 - OTR prices expected to start from around £58,000.
3.0-litre TDI (250PS), 4.2-litre TDI (350PS), 4.2-litre FSI (372PS) and 6.3-litre W12 FSI (500PS) power
130mm increase in wheelbase length, body length extended by the same amount and all incorporated at the rear to maximize passenger comfort. Additional equipment includes heated outer rear seats, sunroof, deluxe four-zone climate control and electric rear and side window blinds
Additional 130mm of wheelbase and body length concentrated at the rear to provide more passenger accommodation. Making its world public debut at the Beijing Motor Show (April 27-May 2). Priced from around £58,000, the new Audi A8 L will also be further refined by an extensively reworked version of the twelve cylinder W12 petrol engine offering further improved power and efficiency.
The 130mm increase takes the length of the new A8 L to 5,267mm, and the wheelbase has grown by the same amount to 3,122mm. Lightweight aluminium employed for all elements bar the safety boosting high strength steel B pillars ensures that the extended Audi Space Frame (ASF) body, like its standard wheelbase counterpart, weighs around 40 per cent less than an all-steel equivalent.
Choice of four engines - the 3.0-litre TDI (250PS), the 4.2-litre TDI (350PS), the 4.2-litre FSI (372PS) and, exclusively for the long wheelbase model, the W12, which in its latest application has been bored out from 6.0-litres to 6.3-litres, and incorporates FSI direct petrol injection in the interest of optimum economy and emissions control. Maximum power has increased by 50PS over the previous version to 500PS, and the 45Nm higher torque peak of 625 Nm arrives at 3,250 rpm.

'Stretch' LWB version of A8 reraches UK. Available from £60,010 OTR, the five-strong A8 L range incorporates an additional 130mm of wheelbase and body length to provide even more exceptional passenger accommodation. It is also further refined by a 6.3-litre, twelve cylinder W12 flagship model that is exclusive to the long wheelbase line-up.
Like the ‘standard wheelbase’ A8, the lengthened luxury saloon is crafted predominantly from aluminium in the interest of efficiency, comfort and driving agility. This approach reduces weight by around 40 per cent compared with an all-steel equivalent, and provides the very best operating conditions for the five engines that power the range - the 3.0-litre TDI (250PS), the 4.2-litre TDI (350PS), the supercharged 3.0-litre TFSI (290PS), the 4.2-litre FSI (372PS) and the heavily reworked W12. This remarkably refined twelve cylinder powerhouse has been bored out from 6.0-litres to 6.3-litres, and is now bolstered by FSI direct petrol injection for improved economy and emissions control. Maximum power has increased by 50PS over the previous version to 500PS, and the 45Nm higher torque peak of 625Nm arrives at 3,250 rpm.
As a result, the A8 L W12 can power to 62mph in just 4.7 seconds, and cruise serenely, where conditions allow, at a governed top speed of 155mph. And with the help of FSI technology, fuel economy belies these figures, with up to 22.8mpg achievable according to the combined cycle test – an improvement of around 9 per cent over the outgoing model which results in CO 2 output of 290g/km.
Thanks to its advanced adaptive air springs, lightweight suspension and latest generation quattro all-wheel-drive, the long-wheelbase Audi A8 manages to combine the polished ride refinement expected of a luxury car with handling poise and agility that would normally characterize performance saloons from one or two classes below.
The full extra length of the A8 L benefits rear-seat passengers, who are able to enter even more easily through wider doors which, in the W12 version, feature power assisted closure. Rear passenger comfort is also further improved by standard seat heating, an upgraded climate control system which enables precise temperature modulation in the two rear ‘zones’ and electrically operated rear window and side window blinds. In the W12, comfort is taken to even greater extremes by replacing the standard rear seat arrangement with two individual sculpted rear seats which can be heated and feature fore/aft adjustable bases and angle adjustable backrests.
March 2011
Audi has developed an A8 long wheelbase model with a next generation mobile broadband communication technology that is faster than current 3G systems. This has been engineered to feature broadband internet with long-term evolution (LTE) technology. LTE technology offers data transfer speeds of up to 100Mbps, which is similar to a fixed-line broadband connection. This means passengers in the prototype can use the LTE broadband connection to stream music, high-definition videos and other data on up to six computer or mobile phone devices with ease. Current 3G connections can only offer data transfer speeds of around 14.4Mbps.
Developed in collaboration with communications pioneer Alcatel-Lucent, the car’s mobile broadband connection is a fourth generation (‘4G’) technology that is hotly-tipped to replace the Global System for Mobile communications (GSM) and the Universal Mobile Telecommunications Standard (UMTS) systems that underpin 3G. LTE allows data to be transferred faster than conventional 3G-technology and modern digital subscriber line (DSL) connections – wired landline broadband. LTE can also cope with large numbers of users streaming data, even at peak times, because of its extra bandwidth.
August 2011
Audi announces that there will be an A8 Hybrid. The luxury saloon combines a 2.0-litre four-cylinder TFSI petrol engine with electric motor for zero emissions driving and in excess of 44mpg.
The Audi flagship model is designed as a highly efficient parallel hybrid. Its 2.0-litre TFSI engine, which has been modified in some areas, generates an output of 211PS and makes a 350 Nm torque peak available between 1,500 and 4,200 rpm. The combustion engine works together with a disc-shaped electric motor which generates 40 kW (54 PS) and 210 Nm.
The permanent magnet synchronous motor is mounted in the space usually occupied by the torque converter in front of the modified eight-speed tiptronic transmission. A multi-plate clutch that operates in an oil bath connects or disconnects the electric motor and the TFSI engine, and does so ultra-precisely and gently in all situations. The smooth and fast-shifting hybrid transmission guides the torque to the front wheels, and its wide gear spread contributes to the efficiency of the Audi A8 hybrid.
The short-term system output of 245PS and the system torque of 480 Nm serve to provide impressively strong response. According to the provisional figures generated by early-stage tests, the Audi A8 hybrid will be capable of reaching 62mph from rest in 7.7 seconds and continuing to a top speed of 146mph while returning in excess of 44mpg in the EU combined cycle test, along with CO2 emissions of less than 148 g/km.
The Audi A8 hybrid can drive at up to 62mph purely on electric power and has a range of up to 1.86 miles at a constant 37mph. This gives the driver the choice of three modes: The ‘EV’ setting gives priority to the electric drive, while the ‘D’ option efficiently controls both the engine and the electric motor. The ‘S’ mode and the tiptronic gate place the emphasis on optimal acceleration. The hybrid saloon has five operating states: with the TFSI engine alone, with electric drive only or in hybrid mode; recuperation and boosting are also possible. Two displays show the driver all operating modes in detail.

New Audi A8 for 2014
On sale in the UK from January 2014 Length of 5.140mm, wheelbase of 2,990mm, width of 1,950mm and height of 1,460mm remain unchanged, and this also applies to the A8 L models with their additional 13 centimetres of wheelbase and body length added in the interest of rear passenger space.
Built around the lightweight aluminium Audi Space Frame, the almost entirely aluminium body of the new generation A8 has been finessed by subtle resculpting of the bonnet, the single frame grille, the front bumper and the lower edge of the headlight units. At the rear, the design of the LED tail lamps has been revised and the bumper in all models bar the S8 now incorporates two rhomboid tail pipes. New chrome elements, new high gloss black window surrounds and five new colours also mark out the updated car.
The even sleeker new standard and long wheelbase bodies house a choice of seven petrol and TDI engines, the majority of which have been revised to improve performance and efficiency. The supercharged 3.0 TFSI petrol engine is boosted from 290PS to 310PS, the V8 twin-turbo 4.0 TFSI moves from 420PS to 435PS, the highly efficient 3.0 TDI clean diesel increases from 250PS to 258PS and the 4.2 TDI clean diesel gains 35PS, taking it to 385PS. Its already mighty torque output is also increased by 50Nm to a prodigious 850 Nm (626.93 lb-ft).
Paired with quattro all-wheel drive, the 4.0 TFSI now powers the A8 from 0 to 62 mph in 4.5 seconds, but under partial load the Audi cylinder on demand (COD) system deactivates four of its eight cylinders to give priority to fuel economy. The most efficient diesel engine is the 3.0 TDI, which returns up to 47.9 mpg, corresponding to 155 grams of CO2per kilometre. All engines satisfy the Euro 6 standard, helped by friction-reducing measures which reduce fuel consumption by as much as 10 per cent.
The luxuriously equipped Audi A8 L W12 quattro occupies the top rung in the A8 line-up. The short and lightweight engine with its W layout displaces 6.3 litres and produces 500PS. It also boasts best-in-class combined fuel consumption of 24.1 mpg, corresponding to 270 grams CO2per kilometre, thanks in part to a newly adopted version of the cylinder-on-demand system developed especially for this model. At low loads, it deactivates the fuel injection and ignition for six cylinders.
The 520PS S8 fulfils a different brief as the ultimate Audi sports saloon. Its 4.0 TFSI engine blasts it from 0 to 62 mph in 4.2 seconds, yet cylinder on demand technology also renders it capable of up to 28 mpg, corresponding to 235 grams CO2per kilometre.
Active Noise Cancellation (ANC), a technology that is also employed in the A8 4.0 TFSI quattro, the A8 L W12 quattro and the A8 hybrid, ensures excellent acoustic comfort by using precise antiphase noise to combat intrusive noise in the cabin while cylinders are deactivated. Active engine mounts also dampen vibration.
At the other end of the spectrum, the overtly efficiency-focused A8 hybrid combines a 2.0 TFSI engine and electric motor to produce a system output of 245PS and system torque of 480 Nm (354.03 lb-ft). The lithium-ion battery in the rear enables purely electric driving at up to 62 mph with a range of roughly 1.9 miles. The A8 hybrid returns up to 44.8mpg and emits 147 grams of CO2per kilometre.
The new A8 is equipped as standard with a fast and smooth-shifting, eight-speed tiptronic automatic transmission which transmits power to all four wheels via the quattro permanent all-wheel drive system in all six, eight and twelve-cylinder versions. A sport differential acting on the rear axle is fitted as standard to the A8 4.2 TDI quattro and the S8 and optional for all other versions bar the hybrids - it distributes power between the rear wheels as required for even greater handling adjustability.

2015 New A8 Sport announced
More luxury and lower CO2 for the Audi A8 range and a new Sport specification with an S8 look. The first versions of the updated 2016 Model Year A8 range can be ordered from 28-4-2015 priced from £59,585 OTR, and the new Sport models from June. UK deliveries will start in the summer.
Offered in standard or Long Wheelbase formats, the latest range features a rationalised choice of engines. Long Wheelbase versions will continue to be available with the highly efficient petrol-electric hybrid drivetrain and with the quintessential Audi luxury saloon power source – the 6.3-litre, twelve-cylinder, 500PS W12. Another formidable petrol engine – the 4.0-litre TFSI with Cylinder-on-Demand technology – will also remain at the heart of the 520PS S8, which is available exclusively with the standard wheelbase.
A pair of TDI units powers standard wheelbase versions, and both are also available in conjunction with the Long Wheelbase body. The 3.0-litre V6 TDI benefits from a slight power increase from 258PS to 262PS and a further reduction in CO2 output from an already impressively low 155g/km to 149g/km (in conjunction with 18-inch wheel), equating to a combined economy figure of 49.6mpg. The 4.2-litre V8 TDI retains its prodigious 385PS and 850Nm of torque, enabling it to propel the predominantly aluminium-bodied saloon to 62mph in a mere 4.7 seconds (standard wheelbase) without ruling out the potential for up to 39.2mpg. CO2 output in this version also falls from 194g/km to 189g/km.
The two TDI engines can be complemented by three levels of specification – SE, SE Executive and a new Sport option, which is reserved for standard wheelbase versions and replaces the Sport Executive trim in the outgoing range. Sport models are now more distinctly marked out visually by a new dynamic exterior package featuring front and rear treatments reminiscent of the flagship S8, combined with pronounced ‘S’ style side skirts and 19-inch alloy wheels in a seven-parallel spoke design.
Not surprisingly all three specification levels are lavish, and include features such as Valcona leather upholstery, double glazing and a 180-watt audio system, combined with advanced technology including all-LED headlights, HDD satellite navigation and the fingertip-sensitive MMI Touch infotainment control system.
Over and above the SE equipment, SE Executive versions add features such as the Audi parking system advanced with reversing camera, the advanced key for convenient locking, unlocking and starting without direct key intervention and powered, hands-free bootlid operation. New additions at this level for the 2016 Model Year include powered door closure, comfort front seats with 22-way powered adjustment and memory function and privacy glass for the rear windows.
In addition to a purposeful new look, the exterior specification of the new Sport models also includes new 19-inch seven parallel spoke alloy wheels and state-of-the-art MatrixBeam LED headlights, which use banks of LEDs that can be individually shut off to avoid dazzling oncoming and leading traffic while retaining full beam illumination. Inside, a 600-watt Bose sound system upgrade and Mobile Phone Preparation – High with Audi connect bringing in-car internet-based services and establishing a mobile Wi-Fi hotspot add to the potential for information and entertainment.
Long Wheelbase TDI, Long Wheelbase W12 and S8 models feature their own bespoke and even more all-encompassing equipment lists.
With its lightweight construction, quattro all-wheel-drive and standard four-mode adaptive air suspension the A8 has always been one of the most agile and controllable luxury saloons. A8 4.2 TDI models capitalise on these assets even more fully with the help of an additional sport differential enabling torque transfer between the rear wheels for greater adjustability, and driveability in all A8 models can be further enhanced by options such as a firmer sport version of the air suspension and a dynamic steering system.
What to watch out for
Problem of engine surge and vibration on April 2012 A8 4.2. Dealer initially denied any problem. VAG Independent reported that the car surged twice on test drive. His computer showed a number of faults: U111300 Functional Impairment due to received fault value; P034100 Camshaft position sender G40 Implausable signal; P049100 Secondary Air system bank 1 Flow too low. In addition, he found that the engine vibrated at various RPM ranges enough to be felt through the seats. He was sure this was not normal with this engine. Dealer then took car back for 3 weeks to fix. Dealer discovered coolant in the transmission fluid indicating failure of the heat exchanger and ordered a new transmission, but by 31-10-2013 the engine problem had still not been solved.
11-02-2014:75k mile 2011 Audi A8 SE TDI Quattro Auto, purchased June 2013 lost all power. Diagnosed at cost of £357 that wiring loom for automatic transmission was corroded, indicating immersion in water at some time. Quoted £4,900 to replace loom because car had been given two intermediate services since purchase date by an independent Audi specialist.
12-01-2017:Series of catastrophes reported relating to a 2015 Audi A8 3.0V6TDI LWB purchased at 11 months old with 5k miles for £47,990 in January 2016 from an Audi dealer for use as a prestigious private hire car for ferrying VIPs to and from airports, etc. Firstly, the purchaser was tied into a finance deal that did not allow the car to be used for private hire. Secondly the car was found to have repaired body damage to a rear door and rear 3/4, intermittently thumping rear suspension, and intermittently failing brakes. A series of poor body repairs followed through 2016, as well as suspension repairs that only rectified the problems for a short period of time. Additionally, the engine is performing poorly, is leaking AdBlue and the rear diff is leaking oil. On solicitor's advice, owner attempted to reject the car and leave it at the dealer's trading address. He had not been advised to reject it jointly to the finance company, which issued a default notice and also pointed out that the finance agreement he had been sold was not for business use. He was asked to collect the car.
09-04-2018:Report of 'Mechatronics' failure of 8-speed torque converter transmission of 2010/60 reg Audi A8 3.0V6 TDI at 60,000 miles.
14-09-2018:Report of failure of Bosch CP 4.2 common rail high pressure fuel pump of 2012 Audi A8 3.0V6 diesel, "which effectively writes the car off. T o clean the system properly would cost about £ 10,000." Apparently a significant problem on higher mileage A8 3.0V6 diesels and other Audis and VWs with the same angine.
