Audi's A7 came out as an outstanding tech car, loaded with innovative cabin and performance features. The S7 is the sport version of that car and takes the tech even higher with impressive performance upgrades.

Like the A7, the S7 gets Quattro all-wheel drive, but it also comes standard with Audi's Sport Differential, which vectors torque across the rear wheels to improve handing. The only letdown in the handling department is the S7's air suspension, which is not quite as capable as magnetic dampers when it comes to controlling sway.

The S7 is a four-door hatchback, providing more accessible cargo area than a sedan with a traditional trunk.

The electric power-steering boost can be adjusted between Comfort and Dynamic settings. It delivers very precise control, but the wheel never has much heft.

An LCD between the speedometer and tachometer shows useful information, such as turn-by-turn directions and trip data.

The S7 comes standard with a powerful, 650-watt audio system, but the optional Bang & Olufsen system is much better.
