This stylish hatchback version of the A6 is an impressive car, although it sacrifices some access, rear-seat room, and visibility in exchange for sportiness and looks. Its rear hatch and generous interior give it practicality, room, and comfort. Handling is responsive and secure, and the ride is steady though firm, particularly on the optional 20-inch tires. The exquisite interior is very luxurious, and the infotainment system proves logical after a bit of familiarization. A midcycle freshening brought tweaks to almost every engine. The smooth, punchy 3.0-liter supercharged V6 is plenty powerful, and an even stronger 450-hp, 4.0-liter V8 powers the S7. If you need more gusto, the RS 7's engine puts out 560 hp.
