The station-wagon version of the S4 TDI has the same technical platform as its sedan sibling.
The 3.0-liter V6 turbodiesel is the same, with 347 hp and 700 Nm (516 lb-ft) of torque. The transmission is the same Tiptronic with 8 speeds which is using a normal torque converter, not the dual-clutch technology seen in other DSG gearboxes. The sports center differential is a self-locking type and can redistribute the torque between the front and rear wheels, but most of the time it will send it to the front wheels.

The interior for the estate was made with family needs in mind. The front seats are bucket-type but the rear bench is almost completely flat. The S4 sedan offers more head-room for the rear-seats occupants. The trunk is only 420 liters (14.8 cu-ft) but can exceed 1435 liters (50.6 cu-ft) with the rear seats folded down.

The Audi MMI has the same large display in the middle of the dashboard. It supports Android Auto and Apple CarPlay and can be accessed either via a touch-screen.

From the outside, an S4 can be easily recognized by the honeycomb front grille structure surrounded by a chrome line around it. The headlights are LED fitted as standard. For the S4, Audi offers standard 18” wheels with 245/40 tires. The customers can choose for 19” wheels fitted with 255/35-series tires.

Performances are very good for this oil-burner with a 0-100 kph (62 mph) in 4.9 seconds. Top speed is a limited 250 kph (155 mph).
