Even the tallest adults will find that there’s room in the front of the RS6 above their heads and enough leg room to stretch out. Shoulder room is generous, too.
There’s a small covered cubbyhole next to the gearlever that will take a mobile phone, but flip up the central armrest and there’s a much larger cubby that’ll accept a wallet, keys and more. Both front door pockets are a decent size and will take a medium-sized water bottle, while the glovebox is big enough to hold more than just the car’s manual.
The generous space continues to the back seats, where a further couple of tall adults will be able to sit in comfort thanks to impressive head and leg room. Seating three adults side-by-side will prove uncomfortable on a long journey, however, because shoulder room is tight and the raised central tunnel hinders foot room for whoever is sitting in the narrow middle seat. You’ll get similar rear passenger space in a Range Rover Sport SVR, though.
The central part of the middle seat’s backrest flips down to provide an armrest and a small amount of covered storage, while each rear door comes with its own well-shaped pocket.
Happily, the Avant has a well-shaped and decently spacious boot, slightly larger than that of the BMW 5 Series Touring. You get a powered tailgate as standard, too, and can pay extra for a hands-free opening system.
