Audi has pledged to only introduce electric vehicles from 2026, but there's still life left in the ol' internal combustion engine. To level up the RS6 Avant and RS7 Sportback, the Four Rings are introducing a hotter Performance derivative with an upgraded version of the twin-turbo, 4.0-liter engine. The potent TFSI V8 now makes 621 horsepower (463 kilowatts) and 850 Newton-meters (625 pound-feet) of torque delivered to a Quattro system.
