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 Lexus LS counters with wireless Apple CarPlay/Android Auto, head-up display, wireless charging, heated front seats, ventilated seats, power tailgate, Mark Levinson audio and ambient lighting that the Audi S6 does not offer. 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 Lexus LS responds with a 3.4L V6 Twin-Turbo Petrol making 310kW and 600Nm, paired to a 10-speed automatic driving the rear wheels. It gets to 100km/h in 5 seconds.
The Audi S6 has the clear power advantage at 320kW vs 310kW. In the real-world sprint, the Lexus LS is 0.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
