Safety Rundown
ANCAP safety ratings have not been published for both models yet. We will update this section when crash test results are available.
Feature Showdown
Both come with modern infotainment systems.
The BMW 7 Series counters with wireless Apple CarPlay/Android Auto, head-up display, wireless charging, panoramic roof, heated front seats, ventilated seats, power tailgate, Harman Kardon audio and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Audi S6 uses a 5.2-litre V10 producing 320kW and 540Nm of torque, sent through a 6-speed tiptronic with dsp and sports program to a AWD layout. It covers the 0-100km/h sprint in 5.2 seconds.
The BMW 7 Series responds with a Petrol making 280kW and 540Nm, paired to a auto driving the rear wheels. It gets to 100km/h in 5.4 seconds.
The Audi S6 has the clear power advantage at 320kW vs 280kW. In the 0-100 sprint (manufacturer-claimed), the Audi S6 is 0.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
