The reason for this move is the fact, that certification to WLTP is not economically viable for A3 Sportback, which is on the market already since 2014 and is expecting the all-new generation in near future.
Audi A3 Sportback e-tron was German company's only plug-in hybrid vehicle, which remained after it also removed Q7 e-tron from the market earlier. Instead, they are now turning to all electric Audi e-tron SUV which was introduced a month ago but is still expected on the market.
