Standard equipment on the 2020 Audi S6 includes a pair of electric turbochargers that virtually eliminate dreaded turbo lag, the time it takes a conventional turbocharger to make noticeable boost pressure (power) after the throttle is depressed. Audi announced in July that each new S6 will feature two electric turbos that make boost in 250 milliseconds, or one-quarter of second. The sport sedan’s performance is expected to at least match that of the 2019 V-8-powered S6 it replaces, but will do so with two fewer cylinders and more than a liter less engine displacement. With no small help from the twin turbos, the 2.9-liter V-6 mild-hybrid drivetrain system makes 444 horsepower and 443 pound-feet of torque, and sprints to 100 km/h (62 mph) in 4.4 seconds.
