After unveiling the new S4 sedan?based on the redesigned, 2017 A4?at the Frankfurt auto show last fall, Audi has now seen fit to unwrap its wagon companion, the S4 Avant. Unfortunately, as Americans, we can only look on in envy.

Output climbs to 354 horsepower and 369 lb-ft of torque, and Audi claims 4.9 seconds for the zero-to-62-mph sprint (versus 4.7 for the sedan).

The standard all-wheel-drive system is rear-biased (60 percent), and an optional sport differential can apportion torque across the rear axle. Ride height is nearly an inch lower than the standard A4, and continuous damping control is optional.
