There are a couple of important similarities between these two cars that show why Audi sedans are so popular. The first is the standard quattro all-wheel drive, a high-performance AWD system first developed for racing in the dirt and snow. The other standard feature is a 7-speed dual-clutch S tronic® with both automatic and selectable gear modes. That means lightning-fast shifts and the versatility of a transmission that is just as comfortable highway cruising as it is in high-speed corner carving.

The compact A5 comes with a 2.0-liter four-cylinder engine that produces 268 horsepower and 295 lb-ft of torque, enough to get the A5 from 0 to 60 in just 5.6 seconds. The A6 packs a more powerful 3.0-liter V6 engine, which produces 362 horsepower and 406 lb-ft of torque. The A6 is bigger than the A5, but the weight difference only comes in at less than 300 pounds, so that extra power translates into an impressive 0-60 time of 4.5 seconds.

Choosing an Audi luxury sedan means that you can enjoy industry-leading technology, safety, and comfort features. The Audi A5 and A6 each come standard with the groundbreaking Audi MMI® infotainment system with revolutionary connectivity features including optional connected navigation. Another standard feature on both models is the stunning Audi Virtual Cockpit display featuring customizable readouts and high-definition views of critical drive information. Genuine leather upholstery is also found on both sedans with several upgrades including both heating and cooling functions. When it comes to driver assistance, available Audi pre-sense city and basic provide an additional layer of confidence and peace of mind behind the wheel. Its available driver-assist technology is able to keep you one step ahead of the unexpected and protected from danger at all times.
