2018 vs. 2019 Audi A8: What’s the Difference?

  • Audi’s flagship luxury sedan has received a big update for 2019.

  • The 2019 Audi A8 has a new look, a new mild hybrid engine and tons of fresh technology.

  • A new turbocharged V6 with a mild-hybrid system improves performance without sacrificing fuel economy.

The full-size German luxury sedan has long been a desirable class of cars for drivers who want it all. In this segment, you’ll find bold, yet understated styling, powerful performance and some of the most luxurious interiors on the market.

Audi’s offering in the full-size flagship sedan segment is the A8, which is all new for 2019. It continues to lead the pack for Audi’s sedans with the ultimate in interior comfort, whether you’re behind the wheel or relaxing in the back seat. Let’s take a look at what’s new for the 2019 Audi A8.

2018 vs. 2019 Audi A8 exterior


The 2018 Audi A8 was already a pretty big sedan and it got even bigger with the 2019 update. It grows by two inches in length and one inch in height. That makes it slightly bigger than one of its closest competitors, the BMW 7 Series. There’s plenty of room to stretch out in both the front and the back seats, making it the kind of car you’d want to be in for an airport shuttle or just for a fancy, roomy family car.

As for exterior design, the 2019 A8 doesn’t look all that different from the 2018 model to the untrained eye. It’s a conservative design with the 2019 model having a more angular grille and more defined body lines throughout the body than its predecessor. The most noticeable difference in the exterior is in back where one wide, horizontal taillamp spans the back of the 2019 car rather than the more traditional taillights on the 2018 model.

Most casual observers might not even notice that the A8 has been updated from the outside, but it has a nice, premium look that will keep you under the radar while looking classy.

2018 vs. 2019 Audi A8 interior


The interior changes in the new Audi A8 is a good example of a nice car getting even nicer. There’s little to complain about from the inside of a 2018 A8, but the 2019 update brings a cleaner design, nicer materials, more room and more features all around.

The biggest difference you might notice is the placement of the infotainment system. The screen mounted to the dash like a tablet in the 2018 model has been replaced with a dual-screen system positioned lower in the center stack and aimed up toward the driver making for ergonomically friendlier operation. The 2019 A8 also replaces buttons with more touchscreen controls.

With a ton of room and very comfortable seats, there isn’t a bad seat in the 2019 A8.

2018 vs. 2019 Audi A8 mechanical


As of this writing, there’s only one engine available in the 2019 A8, but we’ve been told that a turbocharged V8 is on the way that’s expected to make around 460 horsepower.

2018 Audi A8 Engines

  • 3.0-liter supercharged V6; 333 hp, 325 lb-ft of torque; 19 miles per gallon in the city/20 mpg on the highway

  • 4.0-liter turbocharged V8; 450 hp, 444 lb-ft of torque; 16 mpg city/26 mpg hwy

2019 Audi A8 Engine

  • 3.0-liter turbocharged V6; 335 hp, 369 lb-ft of torque; 19 mpg city/29 mpg hwy

The new V6 in the A8 gets its big improvement in torque with no impact on fuel economy thanks to a new mild-hybrid system. It has a 48-volt electrical system that can assist the engine, which improves performance and saves fuel.

One thing that sets the A8 apart from many of its competitors is standard all-wheel drive with the Audi quattro system.

2018 vs. 2019 Audi A8 technology


The latest technology from Audi is on display in the A8 flagship sedan. The 2019 model has a new MMI infotainment system with two screens. It’s highly customizable so you can personalize it to make it uniquely yours. It’s also available with a 12.3-in high-resolution virtual cockpit in front of the driver in lieu of traditional gauges.

In the back seat, there’s available smart remote control. It’s a screen in the rear armrest along with buttons that can adjust climate controls, seating positions and lighting. You can even get a rear seat foot massager. There’s also an available rear-seat connectivity package with two detachable Android tablets and a DVD player.

2018 vs. 2019 Audi A8 pricing


The A8 gets a slight price hike for 2019. The 2018 model has a starting MSRP of $82,500 and the 2019 model starts at $83,800. That puts it toward the top of its class in pricing above the Lexus LS and around the same price as the BMW 7 Series, but not as expensive as the Mercedes-Benz S-Class. The price of the A8 can cross the $100,000 mark and we think it will go quite a bit higher when the V8 becomes available.

2018 vs. 2019 Audi A8 conclusion 


The 2019 update for the Audi A8 might be subtle on the outside, but the upgrades to the interior and technology along with the clever new mild hybrid powertrain make it a pretty significant update to Audi’s flagship.
