The runners enable you to pinion your chattels with an elasticated net, fence suitcases behind an aluminium divider, or barricade something small and awkwardly shaped behind a fabric belt stretched between a pair of movable poles. Complicated? At first, but once armed with an intimate knowledge of luggage entrapment, the threatening slither of unfettered loads should rarely be heard. And as we shall see, the A6 Avant is athletic enough to encourage the kind of driving that will make you only too keen to button down your belongings.
In the cabin
But before considering the intricacies of air suspension and Audi’s new, ice-smooth diesel, more on that boot, which isn’t flaw-free. The rear seat, for instance, doesn’t fold flat – the backrest merely drops onto the cushion below to form a modest ‘ski-slope’.
Since the cushion doesn’t lift up first, to double as a protective bulkhead behind the front seats, objects planted on the folded backrest could make a dramatic entrance between the front chairs under heavy braking. However, a standard extending luggage net, capable of restraining 50kg worth of projectile, can be hooked to the ceiling behind the front seats, though with this barrier in place the car does look as if it’s about to carry a large and unfriendly dog.
Another gripe, for the puncture-prone at least, is that a spare wheel is optional – you get a sealant canister instead. Audi-man also demonstrated the electric tailgate, programmable to rise to a pre-set height.
Like the saloon, the Avant can be had with a bewildering variety of powertrains, as well as front- and four-wheel drive and air- or steel-sprung suspension. The 2.0 TDi (Audi expects this will be the bestseller in the UK) isn’t yet available – it appears during the second half of the year – but the new 2.7 litre, 178bhp V6 diesel was, and a fine thing it is, too.
The crude clatter, throb and rattle of an oil-burner is almost totally absent, even at idle, as is the grumbling increase of revs that is the usual result of a low-gear lunge for speed aboard a diesel. Instead, this satin six revs with enough zest to encourage the odd red-blooded charge at corners.
On the road
Flinging a big wagon around, even unladen, might not sound an especially edifying sport, but this Audi corners so deftly you’ll be back for more. It’s best on fast, open sweepers, but funnelling it through tighter twists is less of a wrestle than you’d expect, especially with an ESP system to counter the odd understeer surge.
No, the steering isn’t the most feel-full, and yes, the brakes could muster more bite, but this car is impressively fleet for a device so large. Since you sit comfortably and can flick at an agreeable gearshift, you’ll find yourself more than mildly entertained.
The test 2.7 TDis came with optional, self-levelling air suspension, allowing you to choose comfort, dynamic or automatic options; left in this last mode it provides a generally pliant ride on the smooth roads of the Spanish test route.
But the odd thump over torn Tarmac had us wondering whether progress might be so placid over British blacktop. If you’re facing an extended, low-speed advance across a puckered piste, opt for comfort. The steel-sprung suspension – standard on all models – is noticeably firmer, but well damped.
