The BMW 5 Series stands out with Harman Kardon audio — features our data doesn't list for the Audi A6. The Audi A6 counters with ventilated seats, Bang & Olufsen audio and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Interior trim differs: the BMW 5 Series gets sensatec synthetic leather upholstery while the Audi A6 offers leather. Climate control is 2-zone in the BMW 5 Series and 3-zone in the Audi A6.
Drivetrain
The BMW 5 Series uses a Petrol producing 140kW and 310Nm of torque, sent through a auto to a RWD layout. It covers the 0-100km/h sprint in 5.6 seconds.
The Audi A6 responds with a Petrol making 180kW and 370Nm, paired to a 7-speed s tronic driving all four wheels. It gets to 100km/h in 6 seconds.
The Audi A6 has the clear power advantage at 180kW vs 140kW. In the 0-100 sprint (manufacturer-claimed), the BMW 5 Series is 0.4s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BMW 5 Series measures 5,060mm long on a 2,995mm wheelbase, 121mm longer than the Audi A6 at 4,939mm (2,924mm wheelbase). The longer wheelbase on the BMW 5 Series generally means more rear legroom.

For towing, the Audi A6 leads with a 2,500kg braked capacity vs 2,000kg. That 500kg difference matters if you regularly hitch up.
