The Car Connection Audi A8 Overview
The Audi A8 is the brand's most exclusive sedan. Pitched against the likes of the BMW 7-Series and Mercedes S-Class, the A8 offers supercharged and turbocharged engines, and a heady dose of technology.
As Audi's flagship, the A8 came with a wide range of engines, including a supercharged V-6, a twin-turbo V-8, and a smooth W-12. In 2015, Audi stopped selling the turbodiesel A8 until parent-company Volkswagen can bring into legal compliance those engines, which polluted more than the automaker initially advertised. In 2017, the automaker shelved the W-12.

The A8 carries through into the 2018 model year with only minor changes, including an available Executive Package trim on V-6 versions of the car. A new model arrives in the spring of 2018 as a 2019 model.
The 2019 Audi A8
The 2019 A8 will be built with Level 3 semi-autonomous driving capability, but as of now, the legality of the system in the U.S. is in question.
The new A8 arrives in the spring of 2018 behind a look that's not much of a departure from the current car. A wider front end, larger air intakes and slimmer LED headlights match up with taillights that span the width of the car, none of which disrupts its executive-sedan mission. Inside, the A8 has wiped nearly all the switches and toggles from the cockpit, and has replaced them with touch-sensitive screens that surround the driver. Gone, and good riddance, touch-sensitive control puck.
Audi has recast the A8's body and made it stronger by blending more materials in with its aluminum frame. The sedan now has some steel panels, some magnesium pieces, even carbon-fiber-reinforced plastic that all reduce weight.
Audi replaces that weight with motors and batteries. The new A8 is its first model line that's completely electrified–not pure electric, but at least mild-hybrid capable. In the U.S., a new 3.0-liter turbo-6 with a belt-driver motor-generator and a 48-volt electrical system turns in a new of about 340 horsepower. Over its lifespan, the A8 in the U.S. will gain twin-turbo V-8 mild-hybrid models, and a plug-in hybrid edition with more batteries and stouter motors, for a 30-mile plug-in driving range and 449 hp net. That A8 L e-tron also will offer a wireless charging system.
The A8 will be fitted with a new active suspension that uses camera data to predict and react to coming road surfaces. Its all-wheel-drive system will be available with a rear differential. A new rear-wheel-steering system will dial in as much as 5 degrees of opposite steer at speeds under 37 mph, for superior parking-lot maneuvers.
Finally, on the technology front, Audi's new array of laser and radar sensors and cameras will give the A8 Level 3 self-driving ability, which means the car will take control of steering and braking and acceleration indefinitely, until it senses higher road speeds, obstacles it can't correct for, or other more complex driving situations. Audi hopes it will be able to sell the system in the U.S., but that will not come until states and the federal government agree on how self-driving cars can be made legal to operate in a systemic way.
The system will engage via a console-mounted button. Other functions, from navigation to climate control, will be operated on the A8's central touchscreens, which have pressure-sensitive haptic feedback. High-end leather, wood, and premium audio will seem quaint by comparison to the A8's new driving technology, but they'll be available.
The third-generation Audi A8
Until the 2019 model makes its debut, Audi will sell the current A8.
In its third generation, the Audi A8 delivered strong performance and good looks, though it isn't quite as dramatic as cars like the Jaguar XJ, the other aluminum-bodied vehicle in the class—or even the current Mercedes-Benz S-Class.
The A8 went on sale in the U.S. in the 2011 model year, with a 4.2-liter V-8 rated at 372 horsepower, whichquoted as having a 0-60 mph time of 5.7 seconds and an electronically limited top speed of 155 mph. A W-12 engine option was added for the long-wheelbase model in 2012.
For 2013, a pair of new engines replaced the former V-8. The lower portion of the current powertrain lineup included a supercharged 3.0-liter V-6 with 333 hp, and a 0-60-mph time of 5.5 seconds; and a 4.0-liter twin-turbo V-8 with 420 hp and a 0-60 mph time of 4.7 seconds. Above them is the performance-oriented S8, which uses a 520-hp version of the twin-turbo 4.0-liter and hits 60 mph in 3.9 seconds. The most expensive was the W-12, a 6.3-liter that makes 500 hp and is good for a 0-60 time of 4.4 seconds. A 3.0-liter turbodiesel V-6 was added for the 2014 model year, available only on the long-wheelbase model, and was rated at 24 mpg city and 36 mpg highway, according to the EPA. In 2016, the 4.0-liter V-8 was uprated to 450 hp.
In 2015, Volkswagen admitted diesel engines in this model illegally cheated federal tests and polluted beyond allowable limits. As part of unprecedented settlements with federal and state governments, Volkswagen agreed to buyback from owners diesel-equipped models of this vehicle. To determine eligibility for all affected Volkswagen, Porsche, and Audi models, Volkswagen set up VWDieselInfo.com for owners. (Owners of affected vehicles can enter their VIN numbers to see if their cars are eligible for buyback.)
Audi Drive Select coordinates steering, powertrain, and suspension with different preset modes and a programmable setting that allows the driver to control each component independently. The A8 feels a bit more nimble than some of the vehicles in its class, but it's still tuned for the tastes of its buyers—not shocking, never abrupt, always collected and calm even when it's accelerating with the quickness of a supercar.
The A8's subtle looks steer attention toward its rich finishes and high-tech features. Its infotainment system uses the latest version of Audi's Multi-Media Interface (MMI), including MMI touch, which allows fingertips to trace out individual letters of destinations, for example. There's built-in wi-fi hotspot capability and Google Earth 3D navigation-system data—the latter brings some of the most detailed, attractive map interfaces in any car. For the fitting final touch, there's a magnificent Bang & Olufsen audio system, with tweeters that rise from the dash surface when the system is switched on. The car's central display screen can also hide in the dash when not needed, for a cleaner look and an unobstructed view out the front.
For 2016, Audi nixed short wheelbase versions of the A8—only the S8 could be ordered with a short wheelbase. In addition to the longer wheelbase, Audi initially offered an A8 Sport (with the uprated V-8) that was made universal for 4.0T models in 2017. A sport exterior package that mimics the look of the S8 was made standard for A8 models in 2017 as well.
Audi A8 history
Preceded in sales by an 8-cylinder version of the A6 sedan called the V8, the Audi A8 was born after the automaker split off the special model and created its signature aluminum space-frame construction.
Audi sold the first-generation A8 from the 1998 model year through 2003. It heralded two firsts for the company: its first mass-produced vehicle with an aluminum space frame and its first car to offer six airbags. The A8 came to the U.S. with a V-8 and standard quattro all-wheel drive for most of that time, while other markets also saw six-cylinder versions as well as a W-12 engine—a 12-cylinder layout that is basically a pair of V-6s joined side by side. Later in the first generation, Audi offered a high-performance S8 in the U.S.
In its second generation, which was sold from 2004 through 2010, the A8 returned with a 4.2-liter V-8 and a six-speed automatic transmission sending power to all four wheels. This A8 was offered in both short- and long-wheelbase models. Audi also brought back the W-12, now displacing 6.0 liters and making 450 horsepower. The second A8 was distinguished by its extra-large grille, which was part of the brand's signature at that time. When the second-generation A8's run ended in 2010, it had reverted to a V-8-only engine menu.
