Elsewhere in the range, there will be a choice of more performance-oriented dual-motor set-ups and efficiency-minded, rear-driven variants offering 0-62mph times ranging from “well under” 4sec to 7sec.
A promised electric Audi RS6 Avant successor could pack more than 600bhp, as previewed by the technically similar Porsche Macan EV.
In this application, the PPE platform accommodates a circa-100kWh floor-mounted battery that gives a claimed 435 miles of range and can charge at a rate of 270kW to gain 186 miles of range from a 10-minute top-up.
Because the battery is sited flat and arranged across the chassis, the earlier concept version of the A6 Avant E-tron is said to offer broadly comparable interior dimensions and load capacity to the current A6 – a trait that will likely carry over to the production car.
However, product marketing boss Niko Martens said EV platforms will ultimately “give more leeway and flexibility, not just in the trunk [boot] but also up the front for a potential frunk”.
Importantly, the electric concept shows how the longer wheelbase afforded by an EV platform allows for more leg room in the front and rear.
The A6 Avant E-tron measures 4960mm long, 1960mm wide and 1440mm tall, which makes it roughly the same size as its ICE forebear.
