iv-Door Sedan 3.0T
iv-Door Sedan 4.0T
4-Door Sedan 3.0L TDI
With TDI range and captivating connectivity, the 2014 Audi A8 adds very long-distance touring to its considerable portfolio of talents.
A longtime rival of the big BMW and Benz sedans, the Audi A8 has taken a longer road to the executive class. Its aluminum space frame grabbed attending when information technology was new, as did a unique W-12 engine. Just it's actually only in the well-nigh recent generation where the A8 has truly arrived--a fully fleshed out entry in this uber-professional niche. The S-Class nevertheless holds an iron grip on the segment, with the 7er a close second, but the A8 now bristles with all kinds of interesting details--and drivetrains--to lure away seekers of high-powered, high-priced German iron.
The A8 tin can now pitch itself as a legitimate contender on almost every level, and a superior on some, including in-automobile connectivity.
Audi builds some stunning cars, just the A8 is just...fine. The big High german sedans aren't charged with drawing stares, though. The A8'south mission is to let its details do the talking on a elementary silhouette with fine proportions. Those details are jewels: the LED lighting front and back looks heirloom, and there's nothing like fender vents competing for attention. The firepower'due south reserved for the cabin, where beautiful wood and patterned metal encounter up with leather and suede to compose a restrained but lavish space.

Audi fits iv engines with five power outputs to the A8. At the top of the range, a 500-hp West-12 engine turns in quick dispatch and a waterfall of torque, only it's not the quickest model. That would be the 520-hp, twin-turbo V-eight-powered S8, which drops sixty-mph runs in iii.9 seconds. A 420-hp version of the same engine slots into the A8, and at the starting terminate of the lineup, there'due south a choice between a 333-hp supercharged gas-powered Five-half dozen, or a turbodiesel Five-6 that later was implicated in Volkswagen'south emissions-cheating scandal.
Audi fits all A8s with an viii-speed automatic and all-wheel drive. Surefooted feel is its forte, but drivers can alter its attitude with Drive Select, which modifies electronic mapping of its air dampers, throttle response, shift schedule, and steering heft. Information technology brings out the all-time of the A8, giving it a improve sense of mechanical harmony, than Drive Select has done in other models.
The A8 comes in two body styles, long- and short-wheelbase. The longer machine stretches 5 inches more than between its wheels for arable rear leg room, without cutting into the A8's handling. At that place'southward room for massaging rear seats, extendable foot rests, power-recline seatbacks, and more on the long-wheelbase car.
MMI is Audi's infotainment interface, and information technology's been refactored this twelvemonth. In add-on to accepting vox and click-wheel inputs, drivers can use a finger to draw characters on a touch on-sensitive puck. Google Maps pipes in live data from T-Mobile to generate the latest, most accurate maps. And of course, in that location are pure luxury touches. A DVD entertainment organisation for rear-seat passengers is nice-but it's even better filtered through a 1,400-watt, 19-speaker Bang & Olufsen Avant-garde sound system.
Showy without excess inside, the Audi A8 is conservative without reading as dull outside.
Sedately styled, salvage for some fabled LED details, the Audi A8 stores upward its glamour for a knockout cabin.
Showy styling doesn't appear oft on cars in the A8'southward form. BMW, Benz, Audi-they reserve the splashy designs for cars like the CLS, the Gran Coupe, the A7.
The A8 lets details do its talking. The silhouette is classic four-door luxury auto, with a long, imposing nose that's big enough to firm a 12-cylinder engine. At the same time it lends the plain-spoken A8 some elegance, helps absorb its long rear doors and broad shoulders. LED lighting dorsum and front end offering act similar the nigh unimposing jewelry. Could Lincoln always describe something this subtle?
Audi saves up all that effusive pattern for the cockpit. Information technology knits together wood, leather, suede, and aluminum in a knockout cockpit with awesome attention to detail. The materials would await at home in a Bentley-a fellow VW Grouping make, no surprise-and they build up to a restrained only lavish issue that doesn't distract from the driving environs.
The details define this space. The transmission shift lever is modeled on the throttle from high-end powerboats, every bit is the sculpting of the upper dash. The optional Bang & Olufsen sound system has twin tweeters that rise similar Whack-A-Moles out of the dash on ability-upwardly. S8 models get carbon-cobweb trim and white-on-gray instruments.

A large sedan with a more athletic feel than its rivals, the Audi A8 has an amazing range of performance as well, from TDI to S8.
Full-size luxury doesn't come without a cost--in cost, or in weight. So while the Audi A8 weighs betwixt 4,400 and 4,800 pounds, it'due south one of the lighter vehicles in the super segment information technology calls home. As with the Jaguar XJ, the A8'due south heavy use of aluminum lightens and brightens its unabridged performance, endowing it with believing handling and relatively great gas mileage, and absolutely great fuel economy with its new turbodiesel engine.
This yr the A8 offers upwards a handful of powertrain choices. Four different engines come up in five unlike outputs.
With either long- or brusque-wheelbase cars, Audi offers a basic supercharged 3.0-liter V-half dozen. It's scored at 333 hp and teams-as all A8s do-with all-wheel drive and an 8-speed, paddle-shifted automatic. With a fiddling more vibration and noise than necessary, the V-6 pumps out prodigious low-end torque on its way to a five.5-second 0-60 mph run and a top speed of 130 mph.
A new turbodiesel offers up 240 hp and 406 lb-ft of torque for 0-60 mph times of half dozen.four seconds and initial EPA ratings of 36 mpg highway. This engine has been implicated in VW'south emissions-cheating scandal, and Audi has set up upwardly a web site for owners who need more than data about repairs and buybacks.
Back in the gas-powered spectrum, the A8 stuffs in a twin-turbo 4.0-liter V-8 with 420 hp and 444 lb-ft of torque, adopting a more visceral feel and dropping 0-threescore mph times to 4.7 seconds. The aforementioned basic engine twists out more turbo boost in the S8 for a total of 520 hp and a 0-lx mph time of 3.9 seconds, as well as a 155-mph top speed.
Atop the A8 range is the luxuriant torque and odd cylinder arrangement of the W-12 flagship engine. The 6.3-liter 12-cylinder pumps out 500 hp and 488 lb-ft of torque, pushing the sedan to sixty mph in four.four seconds.
The A8's automated is a joy. Audi'southward calibration ensures near perfect shifts with smooth engagement, and fuel economy of up to 29 mpg highway in gas-powered cars. Multi-gear downshifts are a snap with either a heavy foot or a quick finger on its paddle shift controls.
The all-conditions traction of its all-cycle-bulldoze system is a big part of the A8's equanimous handling. Audi splits torque 40:60 front to rear, and the system tin shift more than power to the front end (upwardly to lx pct) when traction slips at the rear. On the S8, a separate rear differential can move power side to side to aid cornering and traction. The same diff can exist had on other models in a Sport Plus bundle, packaged with adaptive dampers, summer tires, and variable-ratio steering.
Drive Select is Audi'due south way of maxim "tune it yourself." The system toggles through diverse comfort, sport, and automatic modes to change the behavior of the car'due south steering, interruption, throttle, and transmission. It can't aid, say, to introduce more than feedback in the A8'southward steering, only information technology does assistance coordinate and tailor these systems so, for instance, soft damping doesn't accept to mean slow steering.
The S8 is our selection here. Information technology's not truly a sport sedan, not at this size and non at 4,500 pounds on the curb. In its class it feels like a sprinter, ane with a compliant ride and just enough torso lean to alloy its flagship mission with the ability to exit highway off-ramps at triple-digit speeds.

The A8's interior is fabulous, with a few flaws--one of them beingness tight genu room on standard-wheelbase cars.
The Audi A8 may have a leaner frame than some of its rivals, but it doesn't trade off much interior space or refinement in the name of performance. The contrary is true on long-wheelbase models, which are some of the nearly capable long-distance machines we've driven this twelvemonth, thanks to highly adjustable and form-plumbing fixtures seats, lots of leg room, and ultra-high driving range in the TDI turbodiesel.
With the standard A8 seats come enough of adjustment-eighteen means, in fact. The seats are business firm to the core, but accept a soft layer of padding on top for excellent long-altitude and touring comfort. You may non need the extreme upgrade to 22-way adaptable seats with massaging control and ventilation. With tilt/telescoping steering, it'southward simple to find a bully driving position.
Brusque-wheelbase versions just don't accept the interior space to qualify for this executive mission. Riding on a 117.8-inch wheelbase, the shorter machine has family-sedan rear-seat leg room at best. On long-wheelbase cars, the 122.9-inch stretch between wheels doesn't incur a handling or penalty performance, and it liberates about five inches more space in back.
Climb in dorsum, and the long-wheelbase automobile has the infinite for lanky passengers we'd await in this price class. The long doors make entry and exit painless; once within, the dorsum seats can exist power-adjusted, reclined, heated, and they can exist fitted with an extending footrest and a tray table for an airline-style business-class environs.
With a 13.2-cubic-foot trunk the A8 doesn't have as much baggage infinite equally some very inexpensive family sedans. In-machine storage is good, though, and the only noise that cuts into the cabin is that from the bigger tire sizes. Information technology's easy to drown out with the B&O audio system.

An aluminum frame and high-tech rubber gear give the A8 a higher than usual baseline for safety, though no crash tests accept been performed.
The A8's aluminum infinite frame, its rear-seat side airbags and front-seat knee airbags go to a higher place and beyond the call of safety. But as of at present, neither the IIHS nor the NHTSA has crash-tested i, then information is defective.
The A8 also has a pre-crash system that tightens seat belts, and all-wheel drive is standard.
A rearview camera still is an selection, almost inexcusable in a car this expensive, but parking sensors come standard. On pricey models a surroundings-view camera system shows how information technology's done in the ultra-luxury form.
An expensive package of technology adds night vision to the A8, likewise as bullheaded-spot monitors, adaptive prowl control, and active lane command. The prowl system can finish the car from speeds of up to xix mph, if the car senses an impending collision.
With dark vision, wireless internet, and Bang & Olufsen sound, the Audi A8 is a rolling geekfest.
At this level of executive-luxury realness, y'all expect the Audi A8 to evangelize more than but the basics. It has information technology handled, with a flourish of digital awesomeness that brings a piffling of the desktop and handheld computing feel to the cockpit.
Every A8 gets standard power features, cruise control, leather, a sunroof, navigation, and an AM/FM/CD/XM audio organization with Bluetooth audio streaming, a USB connectivity kit, and Bose premium speakers. Front and rear climate command systems likewise are standard, as are power-operated rear seats and a sunroof.
The infotainment system is governed by MMI. Audi'due south interface accepts inputs by voice, by steering-wheel switches, from a knob controller, and from fingertip gestures "written" on the controller's affect-sensitive surface. MMI has its pregnant pitfalls, simply its command structure seems more intuitive than iDrive from BMW, or COMAND from Mercedes.
It's superior, too, since it tin pipe in data from the T-Mobile network to deliver Google Earth maps, rendered in intuitive, lush graphics on the fundamental screen. It means a monthly subscription fee for your car, but it also means up to 8 devices can connect to an in-motorcar hotspot.
Option packs ladle on more than equipment. A8 sedans with 5-89 and V-half dozen engines can be topped off with ventilated seats, sport tires, and leather console and armrests. Stand up-lonely options including night vision, rear-seat amusement, and full LED headlights. Serious audiophiles volition want to get for the acme Blindside & Olufsen Advanced sound arrangement, which has nineteen speakers, including small-scale tweeters at the forepart of the motel that emerge at startup, forth with more than 1400 watts of ability.
On the new TDI turbodiesel, the options are only slightly reconfigured; one Premium Package includes those 22-way power front seats with ventilation, LED headlamps, and blind-spot monitors, merely nothing that tin't exist found on other models.
As for the functioning S8 edition, information technology comes only in curt-wheelbase form. In addition to the A8's equipment, it gets sport trim, including carbon-fiber and aluminum details within and out; 21-inch wheels and tires; a surroundings-view photographic camera; an Alcantara headliner in coordinated colors or in black; ventilated front seats; Nappa leather; and parking sensors. Options include blind-spot monitors; a 4-spoke steering bike; heated rear seats; and five-spoke 21-inch wheels, likewise as the Bang & Olufsen system, the amusement system, and dark vision.
About everything is standard on the W12 model, including twin LCD screens mounted on the front-seat headrests and Bluetooth headphones. Options come up down to a new Sport package shared with the A8, which includes a sport-tuned pause, differential, driver-selectable steering, and summer tires. There'due south also an bachelor Executive Rear Seat package with a reclining seat, footrest, and seat ventilation, and a cooler box. Blindside & Olufsen sound is a $6,300 option; nighttime vision can be ordered; a package bundles adaptive cruise, lane-keeping help and blind-spot monitors; 4 years of satellite radio can be prepaid at buy; and a five-seat layout is bachelor.

Fuel economy rockets with the A8 TDI'southward 36-mpg EPA highway rating; the W12, it taketh away.
An aluminum body and a fancy eight-speed automated tin can become you far in life, not to mention on the open route. Simply to go for the best fuel economy, large luxury sedans gun for either hybrid drivetrains or diesel engines.
In the 2014 Audi A8, information technology's the latter that drives its EPA numbers into a whole new realm. The newest improver to the A8 lineup, the TDI, comes with a turbodiesel engine with 240 horsepower and 406 pound-feet of torque. It's the least quick performer of the lineup, but it'southward the i with the biggest payoff in range. Audi says its A8 Fifty TDI is EPA-rated at 24 miles per gallon city, 36 miles per gallon highway, and 28 miles per gallon combined. We've recently driven one, and saw 35.6 mpg in a 700-mile trip made upwards of mostly interstate miles.
The TDI complements a pair of engines new for the 2013 model year. Base A8s sport a supercharged 3.0-liter V-6 with stop/get-go that'due south rated at eighteen mpg city, 28 mpg highway, and 21 mpg combined, while both the short- and long-wheelbase models besides tin can exist fitted with a twin-turbo V-8. Short-wheelbase V-8s settle in at 17/28 mpg, or 21 mpg combined, while long-wheelbase sedans are pegged at xvi/26 mpg, or 19 mpg combined.
Gas mileage takes a nose dive with the 500-hp, 6.iii-liter West-12 engine. Equally a long-wheelbase model, the A8 L W12 is rated at thirteen/21 mpg, or 16 mpg combined, figures nosotros'd associate with a large luxury SUV at first glance. That's why you'll see a $2,100 gas-guzzler tariff applied to its sticker, on top of its $134,500 base toll.
