2018 vs. 2019 Audi A6: What’s the Difference?

  • The 2019 Audi A6 doesn’t look much different from its predecessor, but it’s an all-new car.

  • A new mild hybrid powertrain saves fuel without sacrificing performance.

  • The all-new A6 gets a significant price increase over the 2018 model.

It might take a second look to notice, but the Audi A6 midsize sedan is all-new for 2019. While the updates to its exterior styling are subtle, there’s a lot that’s new under its skin from its engine to its new list of technology features. However, are all of the updates worth its hefty new price tag? Let’s see how the all-new 2019 A6 compares to the outgoing 2018 model.


The subtlest difference between the 2018 and the 2019 models of the A6 is the exterior styling. Audi has a distinct corporate design language, and the new A6 sticks to it very closely. Both cars are conservatively styled giving them a look that’s both premium and subdued.

Exterior dimensions of the two A6 models are almost identical with the 2019 model being a little longer and a little shorter giving it a slightly more aggressive stance. Its dimensions put it right in line with other midsize luxury sedans like the BMW 3 Series and the Mercedes-Benz E-Class.


For all of the subtlety of the exterior changes of the new A6, the interior is a big improvement over an already nice cabin. The centerpiece of the new interior of the A6 is the new MMI infotainment system with two screens in the center stack conveniently aimed up toward the driver. This system replaces the previous model’s touchscreen that was mounted to the dash like a tablet. Both systems come standard with Android Auto and Apple CarPlay compatibility.

The rest of the interior of the 2019 A6 is tastefully styled with handsome interior design and high-quality materials. The inside of the 2018 A6 is nice too, but the materials aren’t quite as nice and it doesn’t have the same premium look and feel that the new one has.

With such similar exterior dimensions, interior dimensions are similar, as well. Both variants of the A6 have five seats and can comfortably seat four adults. The A6 is toward the top of its segment for back-seat legroom meaning you’ll hear few complaints from your back seat passengers, even on long trips.


The 2018 A6 was available with two different engines and the 2019 model is available with one. Audi’s quattro all-wheel-drive system is an option on 4-cylinder 2018 models and standard with the V6. For 2019, quattro is standard on all models.

2018 Audi A6 Engines

  • 2.0-liter turbocharged inline four; 252 horsepower, 273 lb-ft of torque; 25 miles per gallon in the city and 34 mpg on the highway

  • 3.0-liter supercharged V6; 340 hp, 325 lb-ft of torque; 20 mpg city/29 mpg hwy

2019 Audi A6 Engine

  • 3.0-liter turbocharged V6; 335 hp, 369 lb-ft of torque; 22 mpg city/29 mpg hwy

With almost identical horsepower, more torque and better fuel economy, the new turbocharged V6 in the 2019 A6 beats the outgoing supercharged engine in both performance and efficiency. That’s thanks to a new mild-hybrid system in the 2019 model. It has a 48-volt electrical system that can assist the engine by generating more torque and saving fuel.

The base engine in the 2018 A6 was a nice lower-cost option than the higher-performance V6, but there’s no 4-cylinder in the cards for the new A6 at the time of writing.


There are a lot of available driver-assistance features that make the 2019 A6 safer and more pleasurable to drive. A few of those available features include adaptive cruise control, a 360-degree camera with sensors to assist with parking and a feature called pre sense that is an array of sensors and cameras so the car knows what’s going on around it at all times and can act accordingly.

Also available in the new A6 is a 12.3-in high-resolution virtual cockpit, which turns your whole dash into a screen that can display important vehicle information like a speedometer and can turn into a 3D map, making navigation a breeze. Other cool tech available includes wireless phone charging and a head-up display with navigation info.


Because of the many aforementioned upgrades to the 2019 model, the new A6 has a much higher price tag than the car it’s replacing. The 2018 A6 has a starting MSRP of $49,700 and the 2019 model starts at $58,900. That increase of almost $10,000 is because of the sole engine option being the V6 and standard AWD. From there, the 2019 A6 can go well into the high $60k range when you get into the higher trims and add more options. The starting price of the new A6 makes more sense when you consider the fact that the starting price of a V6-equipped 2018 model is $58,000.

If the high-performance engine isn’t that important to you, you may want to look elsewhere for a similarly optioned luxury sedan with a milder engine for a more affordable price. For example, the BMW 3 Series and Mercedes-Benz E Class both start lower in the $50,000 range, but aren’t as performance-oriented and don’t have standard AWD. 


The new price of the A6 might be hard to swallow at first, but when you consider what you’re getting, even at the base level, it’s not such a bad deal. It’s still an expensive car, even for its class, but if you want strong performance blended with good fuel economy and the latest technology, the A6 is worth your consideration. It’s a good upgrade over the 2018 model, but it would be nice if a more affordable starting point was still available.
