Unlike the Benz, the A7’s intriguing lines only enhance its practicality. Its 1.1-inch advantage in wheelbase widens the rear door openings and opens up legroom for the back passengers. As in the CLS, artistic shaping of the headliner leaves adequate head clearance for six-footers in back, but the A7’s cargo area, accessed through the powered hatch, is 67 percent larger than the CLS’s trunk. Fold the seats using the releases on the seatbacks if you need to haul not just golf clubs but one or two sand traps as well.
The skeletal stiffness in the A7 is amazing despite the gaping hole in the rear body. Without visible crossbracing, you’d expect some flex, some extra flutter through the floor and doors from the harder impacts, but the A7 absorbs it all. Steering column isolation is likewise wondrous.
In the chassis tests, including our new slalom exercise, the A7 takes the pennant, especially on the skidpad, with 0.93 g worth of grip. Audi opted for a lighter steering heft than Mercedes, which helps hasten quick inputs, but suffused it with progressive loading and responsiveness. Neither car threatens a BMW M3 on steering charm, but both supply the satisfaction suggested by their flamboyant designs.
Pitch and roll are likewise thoroughly dampened in the A7—the four suspension/throttle modes are triggered through the data screen—and we judged the ride, though fairly unyielding on the optional 20s and sport suspension, superior overall. The Benz steps more heavily into potholes and with a greater shock through the rafters. Still, over rough surfaces, the Audi booms and slaps its tires more audibly.
