The mild hybrid sports sedan category has a pair of new faces by way of Audi: the automaker is fleshing out its lineup with performance-oriented and more efficient variations on their A6 and A7 models.

The 2020 S6 and S7 mild hybrids are coming to both Europe and the U.S., albeit in slightly different forms. Both should offer mileage numbers that average out at around 30 MPG, but that’s somewhat speculative at this point and time. All of the mild hybrid series will come with a 48-volt electrical support for their internal combustion engines. But no V8s here—the drivetrain of these variations is built around a V6. The vehicles will receive a 2.9L turbocharged engine that’ll produce in the neighborhood of 450 horsepower.

Most interesting of the body styles represented is the sports wagon, the S6 Avant, which is a contemporary version of the limited-ed model that reached U.S. shores in the early 2000s, and was the best-looking wagon around. The new take on the Avant looks terrific…and fast. Its front end is terse, tasteful and capable, it features some pleasingly angular side creases, and it falls away to a graceful, classy conclusion in the rear.

At this point, however, it is unknown which S6 and S7 mild hybrid body types will be exported to America.
