The new 2027 Audi Q9 and SQ9 overtake the A8 and S8 sedans to become the brand's new flagship models. "U.S. requirements were at the center of the product-development process," said Audi CEO Gernot Döllner, speaking at a preview of the new SUV. AudiWhereas the European Q9 will be powered by a diesel V-6 with 48-volt hybrid assistance, Audi sticks with gas-burners for the USA.
