The first category in which we'll compare these three luxury sedans is performance. Standard power for both the Audi A4 and A5 Sportback comes in the form of a balanced 40 TFSI® (2.0T) 4-cylinder with 201 horsepower and 236 lb-ft of torque. Both also come paired with a seven-speed S tronic® dual-clutch automatic transmission. For A4 and A5 Sportback shoppers craving additional power, drivers can upgrade to an optional 45 TFSI® (2.0T) 4-cylinder with 261 horsepower and 273 lb-ft of torque.
On the other hand, the Audi A6 receives the 45 TFSI® as standard. However, only the A6 can be optioned with an available 55 TFSI® (3.0T) 6-cylinder with 335 horsepower and 369 lb-ft of torque. One commonality between all three models is the legendary quattro® all-wheel drive system. No matter which you choose, you'll enjoy the confidence of the world's most proven and capable all-wheel drive system.
