If the E63 AMG or M5 wagons aren’t quite enough—and you live in Europe—Audi has the hauler for you.
Please make sure all passengers have their seatbelts securely fastened and their carry-on baggage stowed before taxiing to the nearest motorway. Cross-check all instruments and make sure the road ahead is clear. Then say “all call” like you know what it means. Roll onto the entrance ramp and squeeze the throttle gently—but with determination—until the pedal is planted firmly to the floor. Roadside objects are hurled aside and the pavement seemingly narrows as the wailing, awesomely powerful V-10 in front of you—force-fed by two turbos—pulls relentlessly until you hit a gentle, artificial ceiling at an indicated 180 mph. The Audi RS6 Avant is not a plane, but it feels about as close as you can get on the street.
