2012 Audi A8 Reviews

Audi’s A8 is the third member of the big German luxury sedan crew, sharing marketplace space with the BMW 7 Series and Mercedes-Benz S-Class. It boasts the same sharply-cut-suit looks as its peers but, in some ways, is the more technically advanced car. Somehow, however, it was never as popular as the other big Germans. Which is not to say it isn’t worth looking at now.Code-named the 4H series in Audi-speak, the 2010 A8 was available in long- and short-wheelbase forms and with a choice of either a 3.0-litre V6 turbo-diesel with 184kW or a 4.2 litre petrol V8 with 273kW. Just for something left field, Audi also offered a 4.1-litre twin-turbo diesel V8 with 258kW but a stonking 800Nm of torque.All variants used an eight-speed automatic and the A8 was all-wheel drive, which is something its major competitors didn’t have.The car was facelifted for the 2014 model year at which point the magnificent petrol V8 was dropped from the line-up and two revised turbo-diesels appeared. The first was a V6 with 190kW and the other a V8 with 283kW and now 850Nm. The latter was available only as a short-wheelbase car.Standard equipment levels and inbuilt safety were major features of the big Audi and it remains an impressive car to drive and look at. The A8’s other big selling point was its aluminium chassis which helped offset some of the mass of the 'quattro' all-wheel drive system.The A8 is a lovely car to ride in and a decent thing to drive as well. It was set up with comfort in mind, but the quattro all-wheel drive system also lends an added margin of safety in terms of grip in slippery conditions.If anything, though, it lacks the imposing visuals of the BMW 7 Series or Mercedes-Benz S-Class, and from some angles, looks like an enlarged A4 or A6. The interior is pure Audi, which is another way of saying excellent.Because new tech – including safety gear – is usually first seen in the high-spec models from each carmaker, the A8 hit the market as a very safe car for the time. Even now, it boasts some equipment that is still optional on cheaper brand-new cars.Sophisticated cars often wind up with sophisticated problems later in life. The Audi is not perfect in this regard, but it is well made and used quality materials. The fundamentals are good although, like any car, poor maintenance and servicing will show up eventually. And when repairs are needed on a high-end car like this, they won’t be cheap.The first thing to look for in an A8 is any evidence or history of crash damage. That’s because the aluminium chassis and body is difficult to repair properly and requires a specialist workshop to get it right. Even the factory used specialist techniques to build the cars and a lot of the bodywork and panel alignment was somewhat hand-finished. So a close check of the frame and underbody is a must.The A8 was also caught up in the Volkswagen family’s shameful 'Dieselgate' scandal where many brands and models were fitted with devices and software designed to trick the official fuel consumption test for a better number than the car could actually achieve in the real world. The V6-powered A8s were part of this and should, by now, have been returned to Audi for a software update to negate this 'cheat'.On 4.2-litre petrol V8 variants, some owners have reported a problem with carbon build-up on the intake valves. This is due to the direct-injection system where fuel is sprayed directly into the combustion chambers rather than across the back of the intake valve. As such, the valves don’t get washed clean and carbon can build up, affecting performance. To be perfectly fair, this is not an Audi-specific problem and can affect many engines using direct-injection.The A8 hasn’t had too bad a run with safety recalls, but that’s not to say there haven’t been some recalls over the years this generation A8 was on sale.Recalls for the A8 have included problems with the glass sunroof suddenly shattering, transmission oil leaks, power steering leaks in V8 models, engine-bay seals leaking, a potential for incorrect deployment of both front airbags and seat-belt pretensioners and another to check on the oil supply to the engine’s turbochargers.You can find the full details on these recalls by visiting: https://www.vehiclerecalls.gov.au/ .There’s no specific year to avoid here, but the one A8 we’d be very wary of would be an ex-hotel limousine. Flash Aussie hotels often used big German sedans for this task, so take a close look at the rear seat (which will be as worn as the driver’s seat in a hotel limo) and the rear bumper which could be scratched from having a million suitcases dragged over it. The mileage is also likely to be higher than the average A8 thanks to a lifetime of slogging between the city and airport and sitting in traffic in between.And, obviously, any big, sophisticated car like this must have a complete and up to date service history or you could be buying all sorts of trouble down the track.Aside from those ex-hotel limos we were talking about, the A8 doesn’t seem to rack up huge mileages. So, an example with less than 200,000km showing and a clean service history should be able to offer plenty of life for the next owner.Even with its all-wheel drive and aluminium structure, the A8 was hardly a sporty car in an overall sense. So why not make the most of the luxury on tap and find a long-wheelbase version which will also accommodate lanky teenagers in the back much better. And the all-wheel drive will be a great safety bonus when those same kids start learning to drive.While the turbo-diesels have the potential to be very frugal, the Audi 4.2-litre petrol V8 remains one of the sweetest, most sonorous production V8s ever made. So that’s the one we’d go shopping for.There’s a rule in the luxury car market when it comes to second-hand examples. And that’s called the Funnel Effect. Fundamentally, it suggests that while there are enough captains of industry to lease luxury cars brand-new, there aren’t enough private buyers willing to spend that sort of money for a second-hand one. And that’s when trade-in values plummet. The Audi A8 is far from immune to this.Which means there are some great buys out there for a fraction of the cost of the walk-up price when the cars were brand-new. You’ll find decent 4H A8s out there now for $20,000 or so, and they won’t necessarily have huge mileages on board. Pony up to about $30,000 and you are in the realm of some seriously good second-hand A8s.Many of the A8’s driveline components are shared with other high-end Volkswagen Group makes and models, so even though the A8 itself was a fairly niche model, there’s plenty of knowledge and parts available.The Audi brand is also popular with enthusiast motorists, too, so there’s a big online community offering support and parts supply.You need to bear in mind, also, that the Audi is a large, heavy, relatively powerful vehicle so it will consume its fair share of tyres and brake pads and this needs to be factored into annual running costs.

Somewhere in the world, today probably, some clown is filling up the stonking Audi A8 4.2-litre V8 TDI's fuel tank with petrol.That's because the filler has yet to recognise that this near silent, elegant, rapid and authoritatively-styled German is powered by a diesel engine. Getting out the petrol, flushing the fuel lines and replacing a few injectors and filters will be expensive.Very expensive. But doubtless Audi service centres around the world are well practised. How can one blame the guy who filled it up? The A8 4.2TDI idles with almost inaudible assurance, responds instantly to a touch of the accelerator and cuts through freeway traffic with so little fuss and bereft of noise that the clink of Armagnac flutes from the rear seat can clearly be heard.VALUE All this doesn't come for nothing. The limousine will cost $238,500 before it's ready for the road. It is loaded with equipment that will keep you amused for hours - possibly days. If you let children loose in here, you may not see them for months.All this before you turn over the engine. Standard kit starts with the best materials and finest construction ever to grace the cabin of a sub-$500,000 car. It's brilliant.There's also a superb audio and sat-nav system, a touchpad with handwriting recognition, wireless for your iPad/iPhone or Android and Audi's Multi Media Interface that does everything from alter the drivetrain characteristics to help lower fuel consumption.DESIGN It's a lavish and expansive saloon with its hard bits built predominantly from aluminium - it weighs about 40 per cent less than a comparable steel body - and the soft bits from leather, padded vinyl and wool-blend carpet. It has family lines but while its possible to mistake it for an A6 on a damp night, it is clearly too much a limousine to be an A4. There's more room than most people deserve and even the boot is big enough to carry sufficient cash to buy a small country. TECHNOLOGYThe A8 rides on adaptive air suspension and the bi-turbo V8 diesel drives all wheels through an eight-speed sequential automatic. Remarkably, the 4.2-litre engine pumps 258kW/800Nm - that's not a mistake - and yet can get 7.6 L/100km.Not when you max it out over the 0-100km/h spring, however, which can be dashed in a mere 5.5 seconds. Not bad for a 2-tonne, 5.1m top-notch four-door sedan. The MMI also gets a nod for its technological excellence. SAFETY This should go without saying but the A8 is the pinnacle of Audi's safety program. Some of the equipment is optional - and no surprise here but it's expensive - but the standard lifesaving aids should be more than adequate. The A8 previews Audi's pre-sense safety system for avoiding accidents and minimising the consequences, and gets night vision assistant with pedestrian marking and adaptive cruise control with "stop and go'' feature.DRIVINGForget the word diesel and immerse yourself in 800Nm of torque flowing seamlessly to all wheels through a silky ZF eight-cog auto. Wet corners at night dissolve as a dry corner in day with the limpet grip of the tyres and AWD and the canny electronic aids. The quietness is so unnatural that the experience of cruising country highways is almost surreal.Back to reality quickly, though, when overtaking and feeling that torque thrust the car forward without a murmur. Practical car for the city? Probably not. Perfect open-road tourer - also a maybe given it has no proper spare wheel. But the liquidity of its forward motion and readiness to spring to life without flinching, is magic.Audi A8 4.2 TDIPrice: $238,500Warranty: 3 years/unlimited km, roadside assistResale: n/aService interval: 10,000km/12 monthsSafety rating: 5-starsSpare: noneEngine: 4.2-litre V8 bi-turbo diesel 258kW/800NmTransmission: 8-spd auto, AWDBody: 5.1m (L); 1.9m (w); 1.5m (h)Weight: 2070kgThirst: 7.6 1/100km; 199g/km Co2
