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 stands out with wireless Apple CarPlay/Android Auto, head-up display, wireless charging, heated front seats, ventilated seats, power tailgate, Mark Levinson audio and ambient lighting — features our data doesn't list for the Audi S6. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Lexus LS uses a 3.4L V6 Twin-Turbo Petrol producing 310kW and 600Nm of torque, sent through a 10-speed automatic to a RWD layout. It covers the 0-100km/h sprint in 5 seconds.
The Audi S6 responds with a 5.2-litre V10 making 320kW and 540Nm, paired to a 6-speed tiptronic with dsp and sports program driving all four wheels. It gets to 100km/h in 5.2 seconds.
The Audi S6 has the clear power advantage at 320kW vs 310kW. In the 0-100 sprint (manufacturer-claimed), the Lexus LS is 0.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
