In the future, the “e-tron” label will be reserved exclusively for purely electrically driven cars in the Audi portfolio, while the new expanded range of plug-in hybrids will be identifiable by way of their “TFSI e” badging. Depending on the model series, a choice of two variants with differing performance and equipment will be available: a comfort model (50 TFSI e) and a variant with a higher output and more of a performance focus (55 TFSI e or, for the A8 specifically, 60 TFSI e).
