Comparing base trims of both the A4 and A6, these luxury sedans come equipped with identically-sized 2.0-liter turbocharged 4-cylinder engines. The A6 does have an advantage in terms of both horsepower and torque. This continues when you step up to the optional engines for both models. Both sedans come equipped with a responsive 7-speed automatic to help balance efficiency and response. The A6 also comes standard with larger 19-inch alloy wheels and a 19-gallon fuel tank. Conversely, the A4 has a much lower curb weight that helps deliver more athletic handling during high-speed cornering. Ultimately, the choice comes down to your personal preferences.

Audi A4 Interior

Interior Space

The difference in size between the Audi A4 and A6 is evident both inside and out. Both longer and wider than the smaller A4 on the exterior, the A6 unsurprisingly has a slightly larger interior as well. Choosing the A6 means that you'll receive a larger trunk, greater headroom, and greater legroom across both rows of seating. However, first-row dimensions remain similar between the two. The biggest differences are noticed in the rear, making the A6 the better choice for those who frequently travel with back seat passengers. That's not to say that the A4 is an inferior choice! In fact, the leather upholstery included as standard on both models helps all occupants of the vehicle relax and enjoy first-class comfort on the way to your destination.
