Why buy a used Audi A6 Avant e-tron with Exchange and Mart?

Audi may sometimes struggle against its arch-rival BMW in terms of overall sales but in one segment at least, the Ingolstadt maker has traditionally beaten its closest rival: that of large, luxurious Executive-class estates. In its previous combustion form, their A6 Avant out-sold the rival BMW 5 Series Touring nearly two-to-one and was even further ahead of its other key segment competitor Mercedes' E-Class Estate. What then, might the marque achieve with a car that's smarter, safer and clever? This one, the A6 e-tron Avant, Audi's first all-electric luxury estate. Like the alternative A6 Sportback e-tron, it shares nearly all of its engineering with the brand's Q6 e-tron SUV; which means use of the 800V electrical architecture and Premium Platform Electric chassis the Q6 shares with the Porsche Macan Electric. It's claimed to be the most complete large load carrier Audi has ever made. Let's check it out.

About the Audi A6 Avant e-tron

This, even BMW and Mercedes would reluctantly have to admit, is a beautiful piece of engineering. It always has been. In its previous combustion form, the A6 Avant was, after all, the first cars in its class to offer things like bonded-in flush glazing, a galvanised bodyshell, V6 TDI power, four wheel drive and advanced twin-clutch automatic gearboxes. And in new-era e-tron EV guise, the cleverness continues, an extra dose of visual charisma blended with high technology and premium quality unsurpassed in this sector. This car's drawbacks, such as they are, shouldn't bother many potential buyers. No it's still not the most spacious large executive estate in its class - but these days, it's large enough for that not to matter. Yes, the extras can be expensive, but then that's the case with any premium executive car. And it's true that the handling isn't especially aimed at driving enthusiasts, though you can go a long way towards sharpening it by ticking the right options boxes. This then, is a very complete product that will doubtless continue as one of the leaders in its class for many years to come. A thorough case, if ever there was one, of vorsprung durch technic.
